Abstract:
The invention relates to a method for the preparation of cosmetic compositions having the texture of a cream. Said preparation is made at the time when the composition is used and includes bringing the following elements into contact with each other: (A) a liquid phase; (B) a powder containing a gelling agent for the liquid phase (A); and (C) an active cosmetic ingredient, whereby the elements are brought into contact by adding phase (A) to phase (B), subjecting a solid powder containing phase (B) and phase (A) in an immobilized form to mechanical stress, said mechanical stress releasing phase (A). The invention also relates to compositions which can be used in the above context, especially (1) compositions containing phase (B) (to which phase (A) is added prior to use); and (2) solid compositions comprising phase (B) and phase (A) in an immobilized form (and which are transformed into a cream when they are applied to the skin).
