  • Patent number: 5100672
    Abstract: The composite film according to the invention consists of an occlusive layer, and a reservoir layer consisting of a silicone polymer matrix containing a cosmetically and/or pharmaceutically active gelled aqueous phase in the form of dispersed inclusions, the whole being coupled with a removable protection. The matrix comprises a web on the side opposite the occlusive layer. This film can be applied to the skin to cause cosmetically or pharmaceutically active substances to enter via transcutaneous effects. The invention also relates to processes for the preparation of these films.

  • Patent number: 5026552
    Abstract: The material according to the invention comprises a mesh (3) confining a hydratable gel (4) in a thin film is its holes. The gel is used for its properties of absorption of the water provided by a moistening of the surface of the skin; it is rehydrated at least partially and with the mesh resuming its natural flexibility molds to the irregularities of the body; then it dries under the influence of the normal skin temperature, the dry form being resumed while it continues to adhere to the skin. Because the gel is confined in its mesh, it can be pulled off all in one piece, so that the gel thereby performs a skin sloughing treatment.

  • Patent number: 4765922
    Abstract: A skin cleansing composition, in the form of a rod or stick, contains a fatty phase, a water phase and a consistency agent. The consistency agent is a mixture of at least one fatty acid having 12 to 22 carbon atoms and a lactate of the formula. ##STR1## wherein R represents an alkyl or alkenyl radical having 13 to 17 carbon atoms or a mixture consisting essentially of said alkyl and/or alkenyl radicals.

  • Patent number: 4732692
    Abstract: This cosmetic composition contains from 0.05 to 3% by weight of at least one amphoteric surface-active agent chosen from the compounds of formulae (I), (IV), (V), (VI) and (VII), from 0.05 to 3% by weight of at least one anionic surface-active agent chosen from the compounds of formula (VIII) to (XI) and from 0.02 to 8% by weight of at least one nonionic polymer (poly-.beta.-alanine, alkyl and hydroxyalkylcelluloses, starch derivatives) and/or anionic polymers (polyacrylamide, polyacrylamidosulphonic acid and its salts, sodium polymethacrylate), the total concentration of surface-active agent(s) not exceeding 5% by weight. Despite this reduced concentration of surface-active agent(s), which endows it with a satisfactory innocuousness, this composition has an excellent cleansing power. ##STR1## R.sub.1 to R.sub.13, R'.sub.1, n, m, and p have specified meanings.
