Deposition from surfactant systems

摘要

The invention presented in this application relates to a fragrance deposition system for high surfactant applications such as shampoo and body wash. The system will provide a long lasting release of the fragrance and is more efficient at low levels and does not deposit particles that can cause adverse properties.

主权项

1. A surfactant system comprising at least one surfactant and an emulsion of a modified starch and a hydrophobic active ingredient, wherein the emulsion is stable without the at least one surfactant, wherein said modified starch is modified with at least one quaternary ammonium cationic derivative and at least one hydrophobic derivative selected from the group consisting of octenyl succinic anhydride and dodecenyl succinic anhydride on the same polymer backbone, wherein the modified starch contains between 0.2 and 0.7 wt. % of cationic nitrogen and between 3 and 10 wt. % of said hydrophobic derivative, based on the dry weight of said modified starch, and wherein the hydrophobic active ingredient is an oil.
