Abstract
The present disclosure relates to stable aqueous compositions of alkyl sulfates, which are suitable for numerous commercial applications due to their favorable cleaning and foaming properties. More particularly, the disclosure relates to stable aqueous compositions of alkyl sulfates in combination with select hydrophobic agents, such as essential oils.
Claims18
A composition comprising:
- from about 65% to about 85% by weight of the composition of water;
- from about 3% to about 10% by weight of the composition of sodium lauryl sulfate;
- from about 1% to about 15% by weight of the composition of a hydrophobic agent, wherein the hydrophobic agent is selected from the group consisting of geraniol, menthol, carvone, and mixtures thereof;
- from about 1% to about 4% by weight of the composition of a preservative, wherein the preservative is selected from the group consisting of potassium sorbate, sodium benzoate, tocopherol, and mixtures thereof;
- from about 1% to about 15% by weight of the composition of a first solvent, wherein the first solvent is triethyl citrate;
- from about 1% to about 15% by weight of the composition of a second solvent, wherein the second solvent is isopropanol;
- and
- a pH adjusting agent, wherein the pH adjusting agent is selected from the group consisting of citric acid, malic acid, acetic acid, fumaric acid, humic acid, and mixtures thereof;
- wherein the ratio of hydrophobic agent to sodium lauryl sulfate is from about 1:0.66 to 1:5, the composition has a turbidity less than about 20 NTU, and the composition has a b* value of about 0 to about 5.
