Abstract
An improved method for predicting stability of liquid detergent composition, identifying and designing liquid detergent compositions that provide said desired stability, consumer acceptance and performance.
Claims11
A liquid detergent composition consisting essentially of:
- (a) from about 8% to about 18% by weight of a surfactant system comprising from 0.01 wt % to about 9 wt % by weight of the composition of C8-15 alkyl benzene sulfonate and from 0 wt % to about 5 wt % by weight of the composition of a nonionic surfactant;
- (b);
- from about 0.01 wt % to about 5 wt % by weight of the composition of a formulation salt modifier;
- and
- (c) from about 20 wt % to about 85 wt % by weight of the composition of an liquid carrier being essentially free of cumene sulfonate;
- wherein the liquid detergent compositions gives a Formulation Tolerance greater than 33, and has a viscosity of from about 100 to about 800 centipose.
3 more elements
A method of making a liquid laundry detergent composition comprising the steps of:
- a) forming a liquid matrix containing the surfactant system, the liquid carriers being thoroughly admixed by imparting shear agitation to for a liquid phase;
- b) predissolving solid form ingredients to form solution and adding them, except for an enzyme component, to form a mixture;
- c) adding solid form ingredients except for an enzyme component to form a mixture.
- d) agitating the mixture to form a solution or a uniform dispersion of insoluble solid phase particulates within the liquid phase;
- and
- e) adding a enzyme component to the solution or uniform dispersion to form the composition;
- wherein agitation is continued for a period of time sufficient to form compositions having a desirable transparency.

Method for designing a liquid detergent composition comprising the steps of:
- (a) selecting a surfactant system comprising from about 8% to about 18% by weight of total surfactant, wherein from 0% to about 5% of the surfactant system comprises a nonionic co-surfactant and from about 0.01% to about 9% of the surfactant system of a C8-C14 linear alkyl benzene sulfonate anionic co-surfactant;
- (b) selecting a formulation salt modifier;
- (c) selecting a liquid carrier being essentially free of cumene sulfonate;
- and
- (c) calculating a Formulation Tolerance by a formula FT=(HIC/IS)*Σy (weight % of surfactant y in the surfactant system) such that the FT is larger than 33.
