Description

DETERGENT COMPOSITION The present invention relates to detergent compositions suitable for topical application for cleansing and removing oily soil from the human body, particularly for removing make-up from the skin. In particular, it relates to such compositions which are formulated to remove make-up primarily from the face effectively while delivering the clean, refreshed skin feel benefits normally associated with foaming cleansers.

Compositions formulated to remove make-up from the skin are well known. These generally contain high levels of solvents, such as cosmetic oils, which are effective in penetrating and dispersing the oily layer of waxes and pigment-particles which constitutes the make-up soil. Such make-up remover compositions may be designed for wipe-off use, for example, using a cotton pad, or may be designed for rise-off with water, in which case they may also contain surfactants to allow co-emulsification of the make-up base and solvent oil.

However, it is normally found that make-up removers which are thus formulated as oils or emulsions of the water/oil or oil/water type leave the skin with a greasy after-feel. They also tend to be non-foaming, or to provide very little lather during rinse-off. Consumer preference in the main is for a clean, refreshed skin feel after cleansing. The desire to achieve this result, especially when heavy make-up has been worn, frequently results in following a double cleansing routine.

Conventional foaming cleansers, such as bar soaps, facial washes, bath foams, shampoos and shower gels, are well known which provide copious lather on mixing with water, remove light soil (for example sebum) from the skin surface and leave the skin feeling clean and refreshed. However, such products tend to be rather poorly effective at removing heavy soil like make-up, and may also have a noticeable drying effect on the skin.

In recent years, a new class of"2-in-l"cleansers has emerged, which are claimed to combine the benefits of effective make-up removal with the easy rinsability, lathering and skin feel attributes normally associated with foaming cleansers. The failure of these products to win significant market share is a consequence of the compromises that have had to be made in their formulation. Thus, known "2-in-l"cleansers which have been derived from conventional facial foam formulations usually fail to remove make-up completely, whilst those which have been derived from conventional make-up remover formulations fail to deliver the sensory benefits associated with thoroughly clean, refreshed skin.

It is also known to formulate another class of"2-in-1" products which provide both a cleansing and a moisturising benefit from different product phases. For example WO 96/02230 discloses a composition comprising a surface active agent and a benefit agent in which the surface active agent and benefit agent are separate but combinedly dispensable from a single packaging means in a predetermined ratio as discrete domains Separating the benefit agent from the surface active agent is said to result in improved deposition of the benefit agent. However, whereas WO 96/02230 is primarily concerned with depositing a substance onto the skin, the present invention achieves the reverse effect of removing substances from the skin.

One of the problems which may typically be encountered with such dual purpose compositions is that they contain an insufficient level of remover component, or an insufficient amount is effectively active in use, such that removal of heavy soil such as make up compositions is not satisfactory.

Another problem associated with such dual cleansing and moisturising or soil-removing compositions is instability.

According to WO 94/03152, concerne with shower gels comprising a non-soap detergent, silicone oil and cationic polymers, the maximum average droplet size of the silicone oil that can be used is 2 microns, if product stability is to be maintained. The concept of stability however extends to all aspects of the formulation, including dye and antimicrobial stability, in that it is important that the product does not show any signs of deterioration on storage over a period of time.

A further problem which may be associated with prior art cleansing compositions is their low foaming ability. High levels of foaming, together with good foam quality is an important attribute which can heavily influence a users perception of the quality and effectiveness of the product.

We have found a way of formulating such compositions such that they can deliver effective oily soil removal, in particular good removal of make up, while still providing the sensory benefits associated with foaming cleansers.

Further, we have found that the stability of a dual cleansing and soil removing product, and the delivery and effectiveness of the removal agent can be improved by providing a composition in which the cleansing and removal components are separate but combinedly dispensable from a packaging means as discrete domains.

Thus, according to a first aspect of the invention, there is provided a two part cleansing and oily soil removing liquid composition comprising :- a) a first part containing an aqueous domain containing one or more surface active agents selected from anionic, nonionic, amphoteric, zwitterionic and cationic surfactants, soaps and mixtures thereof, wherein the surfactant. containing composition contains an effective amount of a short chain polyol oily soil removal agent; and b) a second part containing an aqueous or non-aqueous domain containing one or more agents for removing oily soil, said aqueous or non-aqueous domain being in a non-emulsified state; wherein the two parts provide domains which are greater than 1000 microns in size, and are separate but combinedly dispensable from a single packaging means as discrete domains.

The composition is suitable for thoroughly cleansing the skin. The oily soil removal agent is included in the composition to remove oily soil, such as make-up from the skin.

The invention also provides a method for improved removal of oily soil from the skin by using the aforementioned cleansing and oily soil removing composition, the method comprising: i) dispensing the surface active agent and the agent for removing oily soil from a packaging means ; ii) applying the surface active agent and the agent for removing oily soil to the human body ; and iii) removing the resulting mixture of oily soil and cleansing agents by rinsing with water.

In a further embodiment,-the invention also provides a packaged cleansing composition for topical application and use. A suitable package for use in this embodiment of the invention is preferably a multiple compartment package, such as a two compartment package.

An advantage of the present invention is that it leads to even better removal of oily soil by a surface active agent containing aqueous liquid composition during use. In particular, it has been found that the inclusion of relatively small amounts of short chain polyol oily soil remover in the surfactant containing part of the two part composition can provide a composition which has superior make up removal, but which avoids some of the disadvantages of prior two part foaming cleansing compositions, in particular related to stability of the composition.

Further, use of the preferred short chain polyol oily soil removing agents in the first surfactant containing part of the composition has been found to be compatible with the preferred surfactants for use in the composition, which include alkyl polyglucosides, monoalkyl phosphates, and mixtures thereof.

Without being bound by theory, it is believed that the oily soil removal agent in the second part of the composition is dispersed into relatively large droplets during rubbing-in of the composition in use, and these droplets readily remove oily soil, such as make-up, from the skin. By appropriate choice of the short chain polyol oily soil removing agent and its level which is incorporated into the first surfactant containing part of the composition, in the case where the former contains water-immiscible components, it is unnecessary to employ emulsion technology to prepare the initial composition. It is also believed that the relatively large droplets of the oily soil removal agent from the second part of the composition, formed in situ during rubbing in of the composition and facilitated by the dispersing of the oily soil removal phase as a single phase or domain, are more effective than relatively small emulsion droplets in removing oily soil.

Make-up removal may be enhanced by delivering the effective agents to the make-up film in locally high concentration.

The relatively large droplets are then though to be reduced in size during use, due to the rubbing action used during application, thus facilitating their dissolution as a dispersed phase in the aqueous surfactant phase of the composition.

The use of a relatively small amount of a specific type of oily soil removal agent in the surfactant phase has been found to boost the make up removal efficiency even further, whilst avoiding the disadvantages which were previously thought to exist when oily soil removal agent was incorporated into the surfactant containing phase, including stability of the first surfactant containing part of the composition. The presence of the oily soil removal agent in the composition has also been found to contribute positively to other attribues of the first surfactant containing part of the composition, including the physical and antimicrobial stability.

Conveniently, the domains of the compositions according to the invention may take the form of stripes of the first and second part compositions, which may conveniently be coextruded side by side (i. e. not mixed) from a two compartment package which has stored the first and second parts of the composition in isolation from each other in separate chambers prior to use.

The invention offers additional avantages not necessarily related to efficacy as such, but more related to the problems of avoiding formulation instability and delivering other consumer benefits, which include: (a) incompatibility of formulation ingredients, which might lead to instability and separation during storage, can be avoided by partitioning the ingredients into different domains; (b) two different structuring systems may be used to provide optimal product viscosity, consumer feel and appearance for each domain, with the structuring systems being more closely adapted to the requirements of each domain ; (c) two different preservative systems may be used for optimal stability for each domain, with the preservative systems being more closely adapted to the requirements of each domain; (d) similarly, two dye/pigment systems for each domain may be used to convey a consumer benefit, for example to renforce the concept that the product is an effective and true 2-in-1 product; (e) formulation ingredients may be kept in separate domains until use when they may be combine and react to give a consumer-perceivable sensation, for example heat generation, change in viscosity or appearance, and in particular a thinning of the combined composition when the surfactant containing part and the oily soil containing parts are mixed, resulting in improved distribution of the composition on the skin and improved oily soil removal; (f) any W-light sensitive material may be kept in only one chamber with W filtering ability, thus allowing a cost saving on quantity of such W filtering packaging; and (g) use of multiple chamber packaging rather than a single chamber may reduce path length of light through the product, thus improving apparent clarity.

The first and second parts of the composition may typically be present in the topical composition at volume ratios to each other of 20: 80 to 80 : 20, preferably from 60: 40 to 40: 60. Conveniently, and for simplicity of packaging arrangements, the topical composition will comprise the first surfactant containing part and second oily soil removing part at volume ratios to each other of 50: 50.

The surface active agent to be contained in the aqueous domain of the composition may be selected from any known surfactants suitable for topical application to the human body.

The surfactant containing part of the two part composition according to the invention also comprises a relatively low level of a short chain polyol oily soil remover. Suitable short chain polyol oily soil removers preferably contain at least two polyol groups, have carbon chain lengths of C4 or less, and have molecular weights less than about 100.

Particularly preferred polyol oily soil removers include propylene glycol and glycerol, especially propylene glycol.

Effective amounts of such short chain oily soil agents in the first surfactant part of topical compositions are about 0.5-15 wt%, preferably 3-15 wt% of the first surfactant containing part of the composition. In some cases a level 10-15 wt% of short chain polyol oily soil removing agent is preferred, though in some circumstances an undesirable reduction in viscosity of the composition may occur when the level of short chain polyol oily soil removing agent is higher than about 12%. At these levels, the make up removal efficiency of the two part composition is found to increase, but without causing adverse effects in relation Go stability of the surfactant component of the composition.

Compositions containing these levels of short chain polyol oily soil removing agent may also contribute to the physical stability of the composition, both in terms of the high and low temperature stability, and also the stability towards any dyestuff which might be present.

In particular when the short chain oily soil remover is propylene glycol, it has been found that levels of propylene glycol in the composition of greater than about 6 wt%, preferably 10% or more of the first surfactant containing part of the composition has been found to contribute positively to the antimicrobial stability of the surfactant containing composition When propylene glycol is used as the oily soil removing agent in the first surfactant containing part, this has also been found to contribute positively to the stability of this part of the composition, in particular when a preferred anionic surfactant species, alkyl polyglucosides or mono-and/or dialkyl phosphates, or mixtures thereof, are used.

It is highly preferred that the surfactant containing phase does not contain any polyethylene glycols, or at least contains less than about 10wt%, preferably less than 5wt% of the surfactant containing part of the composition of polyethylene glycols, since it has been found that these may react adversely with other components of the surfactant containing composition, in particular when mono-and/or dialkyl phosphate surfactants or alkyl polyglucoside surfactants, or mixtures thereof are utilise, thereby adversely affecting the stability of the composition. It has also been found that polyethylene glycols may also be incompatible with many dyes which may otherwise have been desirably included in the surfactant containing part.

The removal agents used in the second part of the 2 part compositions according to the invention are preferably liquids or solutions, and may comprise straight or branched chain hydrocarbons (for example mineral oil, isohexadecane), esters (for example isopropyl palmitate), silicones (for example cyclomethicone), natural or synthetic triglycerides (for example castor oil, sunflower oil, macadamia nut oil, glyceryl tri (2-ethylhexanoate)) and plant extracts (for example Witch hazel, Cornflower extract).

However, conveniently the removal agent may comprise : a) polymeric polyols such as polyethylene glycols (for example PEG 200-600) ; b) polyhydric alcohols such as propylene glycol, glycerol and sorbitol ; c) solvents such as ethanol ; d) nonionic surface active agents having HLB numbers < 10; and f) mixtures thereof.

Particularly preferred removal agents in the second part include propylene glycol and glycerol. In a preferred aspect the removal agents in the second part of the composition are a mixture of propylene glycol and glycerol, preferably in a ratio to each other of 1: 3 to 3 : 1, in which ratios optimum make up removal may be obtained, whilst such compositions have also been found to have good stability, especially low temperature stability.

The domain comprising the removal agent may also contain water, in an amount from 0 to 70%. It may also contain one or more hydrophilic surface active agents which are included to facilitate formation of an oil-in-water emulsion during the final rinsing step, provided that such an emulsion is not present in the formulated domain.

The removal agent is preferably present in the overall composition in an amount of from 1 to 70 wt%, most preferably from 5 to 60 wt%, even more preferably in the region 30-55wtW of the removal agent part of the composition.

In a preferred aspect, the surfactant used in the surfactant containing part of the composition is a surfactant which is electrolyte sensitive, and the oily soil removing agent part of the composition contains an electrolyte, thereby providing a surfactant part of the composition which thins on mixing, and assisting oily soil removal in the manner described above.

It is also a preferred aspect of the invention that the surfactant containing part of the composition contains silica, conveniently of average particle size of greater than 10 microns. Preferred levels of silica are between 3 and 15%, more preferably between 5 and 12%, optimally about 10% by weight of the surfactant containing part of the composition. Silica levels at around this level in the surfactant containing part of the composition have been found to contribute positively to the make up removal capability of the composition, but at higher levels the processability-of the composition may be impaire.

Silicas may also be incorporated at similar levels. in the second oily removal agent part of the composition.

Other fine powders, such as micronised polyethylene having a particle size greater than 10 microns, may also be beneficially included in the topical compositions.

Compositions according to the invention preferably contain relatively low levels of short chain monohydric alcohols such as ethanol, so that the viscosity of the composition does not fall too low Preferably the composition in total contains less than about 5% by weight of short chain monhydric alcohols, though in some circumstances the presence of a small amount of short chain monohydric alcohol (e. g. 2% or more) may be beneficial to the antimicrobial properties of the composition.

Other possible optional ingredients include structurants or thickeners, which may be added to either or both phases of the composition to maintain stability during storage and provide appropriate viscosity during dispensing and use.

Suitable materials for structuring the aqueous foaming surfactant phase include electrolytes which may induce changes in size or geometry of surfactant micelles ; water soluble polymers which are tolerant to surfactants ; and inorganic materials such as clays or amorphous silica.

The choice of preferred thickeners for the second phase comprising the removal agent depends on whether this phase is aqueous or non-aqueous (for example, whether it is oil or polyol based). Suitable thickeners for aqueous or polyolbased phases include hydrophilic polymers ; inorganic materials and mixtures thereof. Suitable thickeners for oilbased phases include oil soluble polymers, waxes, and inorganic materials, particularly those which are hydrophobically modifie.

Further examples of structurants and thickeners are given in the International Cosmetic Ingredient Dictionary, Fifth Edition, 1993, published by CTFA (The Cosmetic, Toiletry & Fragrance Association), incorporated herein by reference.

Other typical components of such compositions may preferably include opacifiers, preferably 0. 05 to 0.5 wt% ; preservatives, preferably 0. 05 to 1.0 wt% ; and perfumes, preferably 0.1 to 0.5 wt%.

In relation to the physical presentation of compositions according to the invention, it is an essential feature of the invention that the oily soil removing solution and aqueous foaming surfactant solution are separate but combinedly dispensable from a packaging means. Typically, the latter may be a single packaging means. Such a packaging means includes those systems which comprise two or more separate compartments.

A wide variety of such packaging means are known in the art, including dual compartment pump dispensers and double tubes which may be configured with the compartments side-by-side or with one inside the other. Particular examples include the multi-cavity dispensing container described in US Patent 5,020,694 and the multi-chamber tube described in US Patent 4,964,539.

It is highly preferable that the aqueous surface active agent and the removal agent may be dispensable from a single packaging means, for example in a predetermined ratio according to the use for which the composition is intended.

An advantage of dispensing the surface active agent and removal agent in combination is that it avoids the inconvenience of having to post-mix the two components.

This is particularly advantageous when the separate components of a composition need to be mixed in precise ratios in order to achieve the desired effect.

Although in the preferred situation, the single packaging means may comprise dual-compartments, wherein the aqueous surface active agent and oily soil removal agent are separately contained, a greater number of compartments is possible, and even a unitary compartment system can be envisaged.

For example, in a unitary system, the discrete domains of the composition of the invention may be realised as separate stripes of surface active agents and of removal agent, or as droplets of one agent suspended in the other, optionally in encapsulated form.

Another method of ensuring that the surface active agent and removal agent are separate involves filling of the separate domains of the composition into a single chamber pack by coextrusion or injection, such that suspended droplets or a striped product is produced in which individual stripes or droplets contain either the surface active agent or removal agent.

Compositions of the invention may conveniently be formulated as products for washing the skin, for example, facial or hand washing compositions, though they may be formulated as bath or shower gels, or products for washing the hair.

The compositions of the invention generally may be pourable liquids or semi-liquids e. g. gels or pastes EXAMPLES The invention will be further illustrated by reference to the following non-limiting examples.

The following compositions represent part of topical compositions according to the invention. Compositions 1-5 represent suitable first surfactant containing parts of a topical composition, whilst compositions represent suitable second parts of the composition containing oily soil removing agent. The parts of the topical composition are suitable for combining, and packaging in and dispensing from twin cylinder packs of the type generally described in US 5,020,694 or US 4,964,539, referred to above.

The compositions may be made by techniques generally known in the art. For example, for the surfactant composition, the components of the composition excluding the silica, polyethylene powder, perfume and preservative may be mixed together, and the silica and polyethylene powder then added and mixed under vacuum. Finally, the perfume and the preservative are added and mixed in. For the second part, the acrylate co-polymer may be dispersed in water under high shear, and the oily soil removing agent and preservative added with stirring to form a homogenous dispersion. The remaining components may then be added with stirring under vacuum.

The components may then be dosed into the chambers of a dual compartment package, which dispenses the two parts of the composition in equal volumes.
