Compositions and methods for controlling deposition of water-insoluble ingredients

摘要

A composition useful in a delivery system for water-insoluble ingredient(s) containing at least one organic phospholipid capable of forming bilayers in aqueous solution; at least one amphoteric surfactant present in an amount by weight equal to or greater than the amount of the phospholipid; at least one nonionic surfactant present in an amount by weight equal to or greater than the amount of the phospholipid; and at least one cationic polymer, wherein the cationic polymer functions to control the amount of water-insoluble ingredient(s) deposited on keratinous substances. A method for treating keratinous substances with the compositions and delivery systems is also disclosed. In addition, the amount of water-insoluble ingredient(s) to be deposited can be controlled by varying the amount of the phospholipid, the nonionic surfactant, or both.
