Description

THICKENED AQUEOUS DETERGENT COMPOSITIONS WITH IMPROVED CLEANING PERFORMANCE
TECHNICAL FIELD
The present invention relates to thickened aqueous detergent compositions.
BACKGROUND OF THE INVENTION
Liquid detergent compositions comprising long chain surfactants such as amine oxides are well known in the art. Such compositions are typically those as in US 4 282 109, EP 274 885, EP 233 666, DE 28 37 880 and EP 30 401.
It is desirable that such compositions have good cleaning properties. However, it has been found that long chain amine oxides do not provide the optimum cleaning performance. It is a first object of the present invention to provide cleaning compositions comprising long chain surfactants with improved cleaning.
In response to this object, it has been found that the incorporation of short chain surfactants is beneficial and meets this object thereby enhancing the cleaning performance.
However, it has been observed that the incorporation of short chain surfactants at amounts needed to enhance performance in such compositions results in the decrease of viscosity of the composition. Yet, it is considered essential that the compositions should exhibit a high degree of viscosity so that the compositions adhere to the vertical surfaces and surfaces inclined to the horizontal. Thus, it is a further object of the present invention to provide a liquid composition which comprises long chain surfactants and short chain surfactants, which retains viscosity.
In response to this object, it has been found that viscosity may be retained even upon the addition of short chain surfactants, by the use of a mixture of amine oxide and alkyl sulphate, more specifically a mixture of a C^-C^g chain amine oxide and a Ci2_c14 alkyl sulphate.
A further advantage of the present invention is that there is no need for an additional thickening agent.
Thickening compositions comprising long chain surfactants are well known in the art.
US 4 282 109 discloses a thickened bleach composition comprising hypochlorite and a thickening amount of a surfactant blend, comprising amine oxide Cιo-ci8 anc* alkyl sulphate C.Q-C12 at a ratio of 3:4 or more.
EP 274 885 discloses thickened bleaching compositions comprising alkali metal hypochlorite and straight chain C^ amine oxide with a mixture of branched and straight chain C^5 amine oxides. There is no mention of short chain surfactants.
EP 233 666 discloses a process for the manufacture of a thickened bleaching compositions comprising hypochlorite, a hypochlorite-soluble surfactant and an alkali metal salt of a fatty acid. The detergent actives include amine oxides, preferably lauryldimethylamine.
DE 28 37 880 covers bleaching compositions comprising alkali metal hypochlorite and mixtures of branched and linear amine oxides of varying chain length, ( 5-C17) for increased viscosity. There is no mention of other long or short chain surfactants.
EP 30 401 covers thickened bleaching compositions comprising hypochlorite and a certain number of product characteristics including pH and viscosity. Mixtures of Cg-C^g amine oxides and fatty acids are preferred as thickening agents. No other surfactants are disclosed.
SUMMARY OF THE INVENTION
The compositions of the present invention have a viscosity of from 40 cps to 4000 cps; comprising a viscosity-decreasing short chain surfactant, said surfactant comprising a hydrophobic portion and a hydrophilic portion, wherein the chain length of the hydrophobic portion is Cg to C^Q.
The composition also comprises a viscosity restoring long chain surfactant mixture. Said mixture comprises an amine oxide according to the formula R1R2R3NO, wherein Rl is a linear C12 to C^g alkyl group and R2 and R3 are independently C^ to C3 alkyl groups and an alkali metal alkyl sulphate according to the formula R4OSO3M, wherein R4 is a C12 to ci4 alkyl group and M is an alkali metal. The compositions also preferably comprise hypochlorite.
All ratios, percentages and parts given herein are by % weight of the total composition unless otherwise specified.
DETAILED DESCRIPTION OF THE INVENTION

According to the present invention the ingredients of the compositions are selected so that the compositions are hypochlorite compatible.
An optional requirement of the compositions according to the present invention is that the pH is greater than 10, preferably greater than 11, more preferably greater than 12. This is achieved by the addition of from 0.4% to 2% of a caustic alkali. Suitable caustic alkalis for use herein include sodium and potassium hydroxide. Compositions according to the present invention comprising hypochlorite preferably have a pH greater than 12 for hypochlorite stability.
Another optional component of the present invention is an alkali metal salt of a Cg-Cig fatty acid. Said fatty acids are used as suds suppressors. Suitable fatty acids for use herein can be any Cg-C^g fatty acid, preferably fully saturated, preferably a sodium, potassium or lithium salt, more preferably the sodium salt. Suitable fatty acids may be selected from caprylic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid and mixtures of fatty acids suitably hardened, derived from natural sources such as tallow, coconut oil, ground oil and babassu oil.
Compositions according to the present invention comprise from 0.1% to 2%, preferably from 0.5% to 1% by weight of the composition of fatty acids.
The detergent compositions herein may additionally comprise as an optional ingredient an organic surface- active agent selected from anionic, nonionic, cationic and zwitterionic surface-active agents and mixtures thereof. The compositions according to the present invention may also comprise a number of additional ingredients such as colourants and perf mes. Additionally, the compositions according to the present invention may comprise silicates used as corrosion inhibitors and silicones as suds suppressors. The compositions according to the present invention are preferably aqueous and comprise from 80% to 95%, more preferably from 85% to 90% of water.
The compositions according to the present invention are prepared by methods well known in the art such as the methods described in GB 1 329 086. The compositions according to the present invention can be prepared by mixing all of the ingredients in a non-metallic apparatus at room temperature or in warm water. If fatty acid is used, it is melted before being added to the mixture. Preferably, the surfactant blend is first prepared by adding the short chain surfactant to the long chain components. Perfume and the alkali metal hypochlorite are then added whilst stirring. Colourants are added after all the other ingredients have been mixed.
The compositions of the present invention may be used for a variety of cleaning purposes such as cleaning hard surfaces whereby said compositions thickened nature results in longer adhesion to the surface than non- thickened compositions.
The compositions according to the present invention can be illustrated by the following examples. EXAMPLES

3. A detergent composition according to claim 1, further characterized in that the ratio of said amine oxide to total amount of said C12-C14 alkyl sulphate and said short chain alkyl sulphate is less than 3 : 4.
4. A detergent composition according to any of the preceding claims, comprising from 2% to 5% of said long chain C^2 to C^g amine oxide.
5. A detergent composition according to any of the preceding claims, comprising from 1% to 4% of said long chain C12 to C14 alkyl sulphate. 6. A detergent composition according to any of the preceding claims, comprising from 1% to 5% of said short chain surfactants.
7. A detergent composition according to any of the preceding claims, wherein said C^-C^g amine oxide is a dimethyl amine oxide.
8. A detergent composition according to any of the preceding claims wherein said amine oxide is a mixture of C^4 and C^g amine oxides.
9. A detergent composition according to any of the preceding claims wherein the preferred C^2 to C14 alkyl sulphates are selected from sodium dodecyl sulphate and sodium lauryl sulphate.
10. A detergent composition according to any of the preceding claims, having a viscosity of from 100 cps to 2000 cps.
11. A detergent composition according to any of the preceding claims, further characterized in that said composition comprises an alkali metal hypochlorite.
12. A detergent composition according to claim 11, comprising from 0.4% to 4% of said hypochlorite.
13. A detergent composition according to claim 11, having a pH of above 10.
