ABSTRACT:
A process for reversibly applying a cosmetic composition to the skin or comprising: a) contacting the skin or hair with the cosmetic composition, the composition comprising at least one amphiphilic material which is capable of forming a water-insoluble liquid crystal phase of greater than one-dimensional periodicity and a cosmetic agent and b) when desired, removing the cosmetic composition by applying to the skin or hair a cleansing composition comprising a surface active agent and a hydrotrope capable of destroying the liquid crystal phase formed in a step a). An advantage of such a system is that the cosmetic agent is strongly adhered to the skin or hair when applied and can be effectively removed when desired.
