Abstract

An in-vitro opacified and structured detergent composition includes a surfactant component present in an amount of about 7 to about 50 weight percent actives and including (1) an alcohol ethoxy sulfate having a C8-C20 backbone that is ethoxylated with from about 1 to about 10 moles of ethylene oxide, (2) at least one non-ionic surfactant comprising an alkoxylated alcohol, and (3) at least one anionic surfactant comprising a linear alkylbenzene sulfonate. The detergent composition also includes water present in a total amount of from about 30 to about 90 weight percent, free fatty acids in a total amount from about 1 to 15 weight percent, a magnesium cation in a total amount of from 0.05 to 1 weight percent, and colloidal particles such as encapsulated fragrances. The composition has a yield point value of at least 0.075 Pa at 20° C.

Dependent claims

A fluid-gel detergent composition having a yield for transitioning between a gel stage and a fluid stage under sheer stress comprising:

A. a surfactant system present in an amount of about 7 to about 50 weight percent based on a total weight of said detergent composition and comprising;
(1) an alcohol ethoxy sulfate having a C8-C20 backbone that is ethoxylated with from about 1 to about 10 moles of ethylene oxide;
(2) at least one non-ionic surfactant comprising an alkoxylated alcohol;
and
(3) at least one another anionic surfactant comprising a linear alkylbenzene sulfonate;
B. water present in a total amount of from about 30 to about 90 weight percent based on a total weight of said detergent composition;
and
C. a free fatty acid or a salt thereof present in an amount of from about 1 to about 15 weight percent based on a total weight of said detergent composition, wherein the salt of the fatty acid is capable of being neutralized in the composition to release the free fatty acid;
and
D. a magnesium salt comprising a magnesium cation component and a counterion component, wherein the magnesium cation component is present in an amount of from about 0.05 to about 1.0 weight percent based on a total weight of said detergent composition;
and
E. colloidal particles,
wherein the colloidal particles are homogenously dispersed in said detergent composition;
wherein said detergent composition has a yield point value equaling to or greater than 0.075 Pa at 20° C.;
wherein before the yield point is reached, said detergent composition acts as a gel or plastic;
and
wherein after the yield point is reached upon applying sheer stress onto said detergent composition, said detergent composition flows freely.

14 more elements

A method of forming a stable, structured and opacified detergent laundry detergent product having a yield point, said method comprising the steps of:

A. mixing a surfactant system, a fatty acid or a salt thereof, water, and at least one addictive ingredient to form a first mixture, wherein the first mixture does not include a magnesium salt;
wherein the surfactant system is present in an amount of about 7 to about 40 weight percent based on a total weight of said detergent composition and comprises:
(1) an alcohol ethoxy sulfate having a C8-C20 backbone that is ethoxylated with from about 1 to about 10 moles of ethylene oxide;
(2) at least one non-ionic surfactant comprising an alkoxylated alcohol;
and
(3) at least one another anionic surfactant comprising a linear alkylbenzene sulfonate;
wherein water present is in a total amount of from about 30 to about 85 weight percent based on a total weight of said detergent composition;
and
wherein the free fatty acid or a salt thereof is present in an amount of from about 1 to about 15 weight percent based on a total weight of said detergent composition, wherein the salt of the fatty acid is capable of being neutralized in the composition to release the free fatty acid;
and
B. mixing the first mixture with a magnesium salt, wherein the magnesium salt comprises a magnesium cation component and a counterion component, wherein the a magnesium cation component is present in an amount of from about 0.05 to about 1.0 weight percent based on a total weight of said detergent composition;
and
wherein after the addition of a magnesium salt, the mixture becomes instantaneously opacified with turbidity value greater than 250 NTU at 20° C. and has a yield point greater than 0.075 Pa;
wherein before the yield point is reached, said detergent composition acts as a gel or plastic;
and
wherein after the yield point is reached upon applying sheer stress onto said detergent composition, said detergent composition flows freely.
