Definitions
- the present invention relates to thickened liquid bleaching compositions.
- the invention relates to thickened liquid bleaching compositions which contain hypochlorite and which are particularly suitable for use in toilet rim mounted toilet bowl cleaning devices.
- Toilet bowls require regular cleaning and disinfecting in order to prevent the accumulation of unsightly deposits, reduce odours and inhibit bacterial growth.
- Liquid hypochlorite-based bleaching agents are widely used and effective in this context. Typically the liquid bleaching agent is squirted neat from a bottle around the bowl and under the rim, with manual scrubbing if necessary.
- a liquid hypochlorite-based bleaching agent in a liquid dispensing device for the toilet rim.
- the formulation has to work at high dilution, due to the action of the flush water.
- a shear thinning rheology is desirable for effective liquid dispensing and dosing.
- an adequate foam profile is necessary so that product efficacy can be perceived by the consumer when the liquid is dosed into the toilet bowl.
- US 4,337,163 discloses a thickened bleach composition containing as the thickening agent a mixture of a first detergent such as an amine oxide and a second detergent selected from alkali-metal salts of saturated C 8-18 fatty acids, alkali metal acylsarcosinates, alkali metal alkyltaurides, sugar esters, and alkali metal C 10-18 alkyl ether sulphates with 1 to 10 moles of ethylene oxide and/or propylene oxide.
- a first detergent such as an amine oxide
- a second detergent selected from alkali-metal salts of saturated C 8-18 fatty acids, alkali metal acylsarcosinates, alkali metal alkyltaurides, sugar esters, and alkali metal C 10-18 alkyl ether sulphates with 1 to 10 moles of ethylene oxide and/or propylene oxide.
- WO 86/01823 discloses a thickened hypochlorite solution with less than 4% amine oxide and one or more cosurfactants selected from sarcosinate, alkyl ether sulphate and alkylsulphonate in amounts less than that of the amine oxide.
- US 4,588,514 discloses a thickened hypochlorite solution with a surfactant system including relatively large amounts of amine oxides, soaps or sarcosinates for thickening and a lesser amount of alkyl ether sulphate for storage stability.
- cleaning compositions comprising hypochlorite, tertiary amine oxide surfactant and sarcosinate surfactant may be found in WO-A-95/33810 and WO-A-97/06233.
- formulations described above are all pourable formulations intended for direct application by the user to the surface to be treated. Because of their increased viscosity, they are said to exhibit superior adhesion to vertical or inclined surfaces such as toilet bowls.
- the present inventors have found that it is possible to formulate a thickened liquid bleaching composition which contains hypochlorite and possess the correct balance of foam profile, rheology and efficacy such that it is suitable for use in toilet rim mounted toilet bowl cleaning devices.
- the present invention provides a liquid hypochlorite bleaching composition which is suitable for use in a toilet rim mounted toilet bowl cleaning device, the composition having a shear thinning rheology and being capable of generating a foam height of at least 3 cm immediately after the toilet flush when used in a toilet rim mounted cleaning device; wherein the composition comprises:
- the invention further provides the use of said composition according to claim 4.
- composition of the invention has a shear thinning rheology.
- compositions according to the invention will have a viscosity between 2500 and 5000 mPa s at a shear rate of 1 s -1 and a viscosity between 1000 and 2500 mPa s at a shear rate of 161 s -1 when measured according to the above protocol.
- composition of the invention is capable of generating a foam height of at least 3 cm immediately after the toilet flush when used in a toilet rim mounted cleaning device.
- the foam height is measured when the composition is dosed at 0.17 g per flush from a dispenser mounted on the rim of a Villeroy & Boch toilet model "Magnum”, with 6 litres of water released per flush.
- liquid hypochlorite bleaching compositions which are thickened with a particular combination of amine oxide and sarcosinate surfactants have the desired properties as described above for suitability for use in toilet rim mounted toilet bowl cleaning devices.
- Suitable amine oxide surfactants for use in thickened liquid hypochlorite compositions according to the invention may be generally described as those tertiary amine oxides of the formula R 2 R'NO, in which each R is a lower alkyl group, for instance methyl, and R' is a long chain alkyl group having from 12 to 18 carbon atoms, for instance a lauryl, myristyl, palmityl, cetyl or stearyl group.
- the inventors have found that the chain length of the long chain alkyl group in the amine oxide surfactant is especially important for delivering optimum properties.
- the total amount of amine oxide surfactant used in thickened liquid hypochlorite compositions of the invention is also important for optimum performance, and it is most preferred that the amount is at least 6 wt%.
- the amount will typically range from 6 to 15 wt%, more preferably about 10 wt%, by total weight of amine oxide surfactant based on total weight of the composition.
- Suitable sarcosinate surfactants for use in thickened liquid hypochlorite compositions according to the invention include acyl sarcosinates or mixtures thereof.
- the acyl sarcosinate surfactants are derived from natural fatty acids and the amino-acid sarcosine (N-methyl glycine).
- Preferred are long chain acyl sarcosinates having the formula RCON(CH 3 )CH 2 COOM, in which M is an alkali metal cation, especially sodium or potassium, and R is a branched or straight chain C 8 -C 18 alkyl group.
- Suitable long acyl sarcosinates include sodium lauroyl sarcosinate, sodium myristoyl sarcosinate, sodium stearoyl sarcosinate, the corresponding potassium salts, and mixtures thereof.
- Sodium lauroyl sarcosinate is most preferred. This material is commercially available from Croda Chemical, UK under the trademark CRODASINIC ® LS30.
- the amount of sarcosinate surfactant that may be used for use in thickened liquid hypochlorite compositions according to the invention preferably ranges from 0.1 to 10 wt%, more preferably from 1 to 5 wt%, and most preferably from 2 to 3 wt%, by total weight of sarcosinate surfactant based on total weight of the composition.
- compositions of the invention comprise hypochlorite in an aqueous matrix.
- the hypochlorite may be a simple hypochlorite salt such as those of the alkali or alkaline earth metals or a compound which produces hypochlorite on hydrolysis, such as organic N-chloro compounds. It is preferred to use an alkali metal hypochlorite such as sodium hypochlorite.
- the amount of hypochlorite present in thickened liquid hypochlorite compositions according to the invention preferably ranges from 0.1 to 10 wt%, more preferably from 1 to 8 wt%, and most preferably from 3 to 6 wt%, by weight of hypochlorite based on total weight of the composition.
- the composition of the invention also contains a source of alkalinity which keeps its pH at or above 11.5, not only during production of the product but also during storage.
- a source of alkalinity is meant a mixture of ingredients which is able to keep the pH at or above the required level.
- the pH of compositions of the invention will preferably be from 8 to 13, more preferably from 9 to 13.
- Suitable sources of alkalinity are known in the art and are generally made up of highly alkaline compounds such as alkali metal hydroxides and alkali metal salts of weak acids such as alkali metal carbonates and silicates.
- Particularly suitable sources of alkalinity are mixtures of alkali metal hydroxide and alkali metal silicate such as sodium silicate.
- composition of the invention may also contain other optional components to enhance consumer appeal such as such as perfumes and colorants.
- Such components should be sufficiently stable to hypochlorite at the pH of the composition to ensure adequate storage stability.
- Ultramarine Blue (UMB) and copper phthalocyanines are examples of widely used hypochlorite-stable pigments which may be incorporated in the composition of the present invention.
- composition of the invention is particularly suitable for use in toilet rim mounted toilet bowl cleaning devices.
- a preferred type of dispenser for use with the composition of the invention may be generally described as a device which is adapted to be suspended over the toilet rim, and which comprises a cartridge adapted to contain the composition, and a dispensing mechanism for the composition which releases the composition in response to the action of the flush water.
- a most preferred type of dispenser for use with the composition of the invention comprises a reusable holder which is adapted to engage with the cartridge, which is replaceable when empty.
- the holder incorporates a securing means such as a hook which is shaped to be clipped over the rim of the lavatory bowl, and has a distribution plate which projects into the path of flushing water from the lavatory when the dispenser is secured to the rim of the lavatory bowl.
- the plate typically bears a wicking device to spread the composition over the surface of the plate.
- the wicking device may for example be a porous pad, or more preferably a system of channels which direct the passage of the composition by capillary action.
- the composition is delivered from the cartridge to the surface of the plate where it is exposed to flushing water and washed off the plate and carried to the lavatory bowl.
- a composition according to the invention was prepared having ingredients as shown in the following Table: INGREDIENT LEVEL wt% sodium lauroyl sarcosinate (1) 2.00 C12-18 alkyl dimethyl amine oxide blend (2) 10.00 sodium hydroxide 1.00 sodium silicate 1.00 sodium hypochlorite 4.87 Demineralised water, minors To 100% (1) Added as CRODASINIC ® LS30, commercially available from Croda Chemicals (30 wt% active solution) (2) A blend of amine oxide containing 25 wt% C 12 alkyl dimethyl amine oxide, 40 wt% C 14 alkyl dimethyl amine oxide and 35 wt% C 16 and C 18 alkyl dimethyl amine oxide (each by weight based on the total weight of amine oxide).
