Abstract
Structuring systems, specifically thread-like structuring systems and/or disk-like structuring systems wherein structuring agents aggregate together to form disk-like structures that can interact with other disk-like structures to result in a structuring system, and processes for making such structuring systems, stabilized liquid compositions comprising such structuring systems, systems that utilize such structuring systems for stabilizing liquid compositions, and methods for utilizing the stabilized liquid compositions to provide a benefit, are disclosed.
Claims47
A water-containing liquid detergent composition comprising:
- a) a fabric substantive agent having limited solubility in said liquid detergent composition;
- b) a crystalline, hydroxyl-containing stabilizer;
- and optionally,
- c) a nonsurfactant adjunct suitable for laundry or dishwashing detergents wherein said adjunct is soluble in said liquid detergent composition.
An aqueous laundry and/or dishwashing liquid composition comprising a thread-like structuring system and a benefit-providing material wherein the thread-like structuring system stabilizes the benefit-providing material such that the benefit-providing material provides its benefit upon use.
A stabilized water-containing liquid laundry detergent composition comprising a thread-like structuring system having an average aspect ratio of from about 1.5:1, preferably from at least 10:1, to about 200:1.
A stabilizing system wherein an aqueous laundry and/or dishwashing liquid composition is stabilized by an effective amount of a thread-like structuring system.
A water-containing liquid detergent composition comprising:
- a) a defoaming and/or aesthetic agent having limited solubility in said liquid detergent composition;
- b) a crystalline, hydroxyl-containing stabilizer;
- and optionally,
- c) a nonsurfactant adjunct suitable for laundry or dishwashing detergents wherein said adjunct is soluble in said liquid detergent composition.
An aqueous, heavy-duty laundry detergent comprising:
- at least 5% water, preferably at least 20% water;
- 5% to 40% of a surfactant system comprising anionic, nonionic or mixed anionic/nonionic surfactants, optionally including amine oxides;
- from 0.1% to 5% of a crystalline, hydroxyl-containing stabilizer;
- from at least about 0.01% to about 5% of detersive enzymes;
- from 0.1% to 10% of a fabric-substantive agent selected from silicones having all of a cationically charged moiety, a silicon-containing moiety and a polyoxyalkylene moiety;
- said composition having a pH at 1% in water of at least 7.5.
A stabilizing system wherein an aqueous laundry and/or dishwashing liquid composition is stabilized by an effective amount of a structuring system comprising a thread-like structuring system and a non-thread-like structuring system.
A method for increasing the viscosity of an aqueous laundry and/or dishwashing liquid composition comprising the step of adding an effective amount of a thread-like structuring system to the liquid composition such that the viscosity of the liquid composition is increased compared to the viscosity of the liquid composition without such as structuring system.
A method for increasing the viscosity of an aqueous laundry and/or dishwashing liquid composition comprising the step of adding an effective amount of a structuring system comprising a thread-like structuring system and a non-thread-like structuring system to the liquid composition such that the viscosity of the liquid composition is increased compared to the viscosity of the liquid composition without such as structuring system.
A water-containing liquid detergent composition comprising:
- a) a fabric substantive agent having limited solubility in said liquid detergent composition;
- b) a material of the formula:
- Z—(CH(OH))a-Z′
- where a is from 2 to 4;
- and Z and Z′ are hydrophobic groups;
- and optionally,
- c) a nonsurfactant adjunct suitable for laundry or dishwashing detergents wherein said adjunct is soluble in said liquid detergent composition.
