Description
A CONCENTRATED CLEANING COMPOSITION
Field of the invention
The present invention is in the field of cleaning compositions. In particular, it relates to a concentrated liquid cleaning composition for providing a liquid detergent on dilution in water.
Background of the invention
Consumers are involved in various cleaning activities as part of their household chores. Some of them may prefer to use cleaning compositions or products for better performance. Often products are available in various formats such as, bar, powder, liquid, tablet, or unit dose pod etc., and liquid is one of the preferred formats by consumers.
A cleaning composition in liquid format may contain detersive actives, sequestrants, bleaching agent, anti-foaming agent, enzyme, preservatives etc. Apart from these, it also contains significant amount of water. Preferably, water acts as carrier for said ingredients and helps in forming a homogenous composition. It also helps in providing a rheology suitable for dosing and applying the composition easily on the surfaces to be cleaned. However, high water content makes the product bulky. Thus, packaging of the product requires substantial amount of materials, such as, polyethylene, polyethylene terephthalate etc. The packaging materials are often sourced from non-renewable resources. In this regard there are continuous efforts to reduce such consumptions.
One of the ways to reduce such consumptions, is to have a product in concentrated format. A consumer is expected to dilute such product in water to form a liquid detergent and store it in a container. Such products are often termed as ‘Do it Yourself’ or abbreviated as ‘DiY’, which implies that a consumer prepare their own detergent from a precursor/concentrate by diluting it in water. Further, in-use, the consumer doses an aliquot of the liquid detergent into to a bucket/bowl of water or in tub of a washing machine forming a wash liquor and use it for washing. Thus, same product may be available in three forms, namely, concentrate, liquid detergent and wash liquor depending on extent of dilution. Typically, they vary in detersive content. Moreover, they differ in attribute and functionality. For example, wash liquor typically lowest in detersive active content among the forms, has viscosity like water and used immediately after preparation. On other hand, liquid detergent has attributes, such as, efficacy, appearance, sensory, stability etc., and they are supposed to be stored in a container for later
use. It is expected that those attributes are such that consumers may relates the liquid detergent to conventional liquid detergents available in market.
Viscosity of liquid products is one of the key attributes. It can be correlated to pourability of the product. It also often relates to sensory of the product. For example, consumers relate high viscosity to high amount of detersive agent in the product, which drives manufactures to provide liquid detergents in viscous form. Thus, it is desired that the liquid detergent formed on dilution of a ‘DiY’ product has viscosity such that a consumer can relate it with conventional liquid detergents available in market.
One of the challenges of developing concentrated liquid products is to achieve desired viscosity of the liquid detergent formed on dilution. Typically, the viscosity of concentrated products drops with dilution in water resulting in low viscous liquid. This may not be preferred by consumers. It is possible to formulate a concentrated product with significantly high viscosity by adding a thickener such that when diluted it provides a viscous liquid detergent similar to conventional liquid detergent. However, such concentrated products face pourability issue and may not be liked by consumers either.
In this context, WO 2014/173659 A1 describes a fluid cleaning composition comprising: (a) a surfactant combination comprising: (i) a synthetic surfactant; and (ii) a glycolipid biosurfactant which is present at a level in the range 10 to 95 %wt. of the total surfactant in said surfactant combination, and (b) a benefit agent suspended in said fluid cleaning composition characterised in that the benefit agent comprises an encapsulate.
WO 2020/126592 A1 relates to a liquid detergent composition comprising (a) from 8 to 30 %wt. of a surfactant system comprising: (i) a primary surfactant of the formula R1-(OR')n-O-SO3 -M+, wherein: R1 is saturated or unsaturated C8 to C16 alkyl chain; R' is ethylene; n is from 1 to 18; M+ is a suitable cation which provides charge neutrality selected from sodium, calcium, potassium and magnesium; and (ii) at least one secondary surfactant selected from amphoteric surfactants, alkyl sulphates, alkylbenzene sulphonate and derivatives; (b) from 0.001 to 0.2 wt percent of polyethylene oxide having molecular weight higher than 200,000 g/mol, (c) from 0.05 to 2 %wt. of fatty acids comprising a saturated hydroxy fatty acids having 8 to 18 carbon atoms, saturated non-hydroxy fatty acids having 8 to 18 carbon atoms, or mixtures thereof; (d) 0.1 to 5 percent by weight of an inorganic salt selected from the group consisting of sodium chloride, magnesium sulphate, sodium sulphate and combinations thereof; and (e) water.
DE 19648439 discloses use of mixture glycolipid and surfactants for manufacturing manual dishwashing detergent.
Instead of the prior arts, there is a need for an improved concentrated cleaning composition for providing a liquid detergent on dilution in water. It is desired that the concentrated composition has easy pourability, yet on dilution provides a liquid detergent matching one or more attributes of conventional liquid detergents.
Surprisingly, the present inventors have found that a concentrated cleaning composition comprising a combination of a rhamnolipid, a hydrotrope and a water-soluble inorganic salt provides a liquid detergent on dilution, which have a viscosity similar to that of the conventional liquid detergents.
Summary of the invention
