Inverse latex based on white mineral oils, squalane or hydrogenated polyisobutene, cosmetic compositions, dermocosmetics, dermopharmaceuticals or pharmaceutical compositions containing them

摘要

Composition comprising oil and aqueous phase, at least one water/oil emulsifier and at least one oil/water emulsifier, in form of auto-invertible inverse latex comprising 20-70 (preferably 25-50) wt.% of branched or crosslinked polyelectrolyte, and containing solvent component of oil phase in form of squalane, hydrogenated polyisobutene, or white mineral oils, is new. The composition contains polyelectrolyte in form of either homopolymer based on monomer with weak acid group partially or totally salt-converted, or in form of copolymer based on monomer with strong acid group, copolymerized either with at least one monomer with weak acid group, or with at least one neutral monomer. Independent claims are also included for: (1) cosmetic, dermo-cosmetic, dermo-pharmaceutical, or pharmaceutical preparation, in form of milk, lotion, gel, cream, soap, bath foam, balm, shampoo or conditioner, including 0.1-10 wt.% of composition as claimed; and (2) use of composition as claimed in production of cosmetic, dermo-cosmetic, dermo-pharmaceutical, or pharmaceutical preparations.
