Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

【Technical field】

The present invention relates to stable aqueous heavy duty gel laundry detergent compositions containing anionic surfactants, fatty acids, and especially selected structurants to provide exceptional cleaning benefits and phase stability. This structurant consists of conventional detergency builders such as sodium sulfate and optionally citrate. The anionic surfactant component consists of linear alkyl benzene sulphonate, alkyl sulphate and alkyl ethoxylated sulphate.

[0002]

[Background Art]

In the prior art, there are many examples of laundry detergent compositions having good cleaning properties. While many of these are liquids, the formulation of gel detergent compositions prescribes a number of issues including high viscosity at the poured shear rate, instability on storage, unacceptable grease screening, and undesirable appearance. Presented to the trader.

[0003] Attempts to formulate gel laundry detergent compositions in the past have involved the use of conventional builders, such as citrate, as structurants. These compositions are gels and have reasonably good phase stability. However, builders are expensive and often undesirable in formulating detergent compositions having the amount of builder required to structure a heavy duty gel detergent composition. Therefore, there is a continuing need for supplemental or alternative structurants for use in aqueous heavy duty gel detergent compositions that are inexpensive and provide the same or improved structuring.

[0004] Aqueous heavy duty gel detergent compositions containing certain anionic surfactants, fatty acid surfactants and certain structurants including sodium sulfate provide excellent cleaning performance and attractive product properties, That is, it has now been found that it is structured, phase stable and has a rheology that allows easy pouring from the product container.

[0005] Without being limited by theory, it is believed that these novel compositions have an internal structure consisting of a planar lamellar phase. The presence of such a phase in the detergent composition may be determined by light or electron microscopy.

BEST MODE FOR CARRYING OUT THE INVENTION

According to the present invention, a stable aqueous heavy-duty gel detergent composition surprisingly comprises a specific anionic surfactant, a fatty acid surfactant and a structurant comprising sodium sulfate specified in the relative proportions specified below. It has now been found that it is prepared when combined. Specifically, by weight of the composition: (a) about 10 to about 40% by weight of the composition, an anionic surfactant system; (b) about 5 to about 20% by weight of the composition, a fatty acid; and (c) About 0.5% to about 6%, preferably about 2%, of a structuring agent containing sodium sulfate
A gel laundry detergent composition is defined, characterized in that it comprises from about 3% to about 6%, more preferably from about 3% to about 5%, most preferably from about 4% to about 5%.

Preferably, the structurant further comprises, in addition to sodium sulphate, a detersive builder (preferably citrate). The weight ratio of sodium sulfate to detersive builder is
From about 10: 1 to about 1:10, preferably from about 5: 1 to about 1: 5, more preferably from about 3: 1 to about 1: 3, most preferably from about 2: 1 to about 1: 2. Additional builders suitable for use in the present compositions are carboxylate, polycarboxylate, aminocarboxylate, polycarboxylate, carbonate, bicarbonate, phosphate and phosphonate. Sodium sulfate is preferably present in the detergent composition from about 0.25% to about 6%, more preferably from about 0.5% to about 5%.

The anionic surfactant system comprises about 5 to about 25% by weight of the composition of an alkyl polyethoxylate sulfate (where the alkyl groups have about 10 to about 22 carbon atoms and the polyethoxylate chains have about 0.5 to about 15, preferably about 0.5 to about 5 ethylene oxide moieties). And the detergent composition preferably contains a detergent material selected from the group consisting of detergent amines, modified polyamines, polyamide-polyamines, polyethoxylated polyamine polymers, quaternary ammonium surfactants, and mixtures thereof.

[0016] The anionic surfactant system can include a surfactant selected from the group consisting of linear alkyl benzene sulfonate, alkyl sulfate, alkyl ethoxy sulfate, and mixtures thereof.

The composition is structured and has a specific rheology. The rheology is given by the following equation: η = η ₀ + Κγ ^(n-1) (where η is the viscosity of the liquid at a given shear rate, η ₀ is the viscosity at an infinite shear rate, and γ is the shear rate Where n is the shear rate exponent and Κ is the consistency).

Electrolyte- Without being limited by theory, it is believed that the presence of the electrolyte acts to control the viscosity of the gel composition. Thus, the gel properties of the composition are affected by the choice of surfactant and by the amount of electrolyte present. In a preferred embodiment of the invention, the composition comprises 0% of a suitable electrolyte or an acid equivalent thereof.
To about 10%, more preferably about 2% to about 6%, and even more preferably about 3% to about 5%. Sodium citrate is a highly preferred electrolyte for use herein.

"Solvent" means a solvent commonly used in the detergent industry, including alkyl monoalcohols, di- and tri-alcohols, ethylene glycol, propylene glycol, propanediol, ethanediol, glycerin and the like. By "hydrotrope" is meant a hydrotrope commonly used in the detergent industry, including short-chain surfactants that help solubilize other surfactants. Other examples of hydrotropes, cumene sulfonate, xylene sulfonate or toluene sulfonate, urea, C ₈ or less short-chain alkyl carboxylates, and C ₈ include the following short-chain alkyl sulfates and ethoxylated sulfates.
