摘要:
An emulsifier for use in making PIT or microemulsions is comprised of (a) from 45 to 60% by weight of a partial glyceride, (b) from 5 to 25% by weight of an alcohol polyglycol ether, (C) from 5 to 15% by weight fatty alcohol, and (d) from 0 to 15% by weight of a wax ester wherein the monoglyceride content of the partial glyceride is less than 50% by weight and wherein the monoglyceride is comprised of palmitic and stearic acid residues in a ratio by weight of from 40:60 to 60:40. Emulsions containing these emulsifiers neither gel nor crystallize in storage.

The disclosed invention provides wax dispersions with an average particle size of 0.5 to 100 μm containing (a) a wax phase with a melting point above 25° C. which contains at least one oil or wax component selected from dialkyl(ene) ethers, dialkyl(ene) carbonates, dicarboxylic acids, hydroxyfatty alcohols, and mixtures thereof and at least one emulsifier, and (b) a water phase. The wax dispersions are particularly useful as a basis for cosmetic preparations and, more particularly, for impregnating and wetting utility and sanitary wipes used for personal hygiene and body care.
摘要:
The invention relates to a glycerol ether mixture which consists essentially of a) at least one C12-22 glycerol monoalkyl ether, b) at least one C12-22 glycerol dialkylether and optionally c) at least one C12-22 glycerol trialkyl ether and/or d) at least one C12-22 fatty alcohol, components a) and b) together making up at least 50% by weight of the glycerol ether mixture and the ratio by weight of component a) to component b) being in the range from 3:1 to 1:2. The invention also relates to a process for producing the glycerol ether mixture and to cosmetic compositions containing the glycerol ether mixture.

摘要:
The disclosed invention relates to a cosmetic composition containing at least one branched oligo-α-olefin, characterized in that the side chains at one branch point at least are ethyl, propyl or longer branched alkyl chains, the branched oligo-α-olefin being obtainable by oligomerization of a) at least one branched α-olefin containing 5 to 18 carbon atoms, b) at least one linear α-olefin containing 4 to 10 carbon atoms, c) a mixture of a branched α-olefin containing 4 to 18 carbon atoms and a linear α-olefin containing 3 to 18 carbon atoms or d) a mixture of various branched α-olefins containing 4 to 18 carbon atoms and linear α-olefins containing 3 to 18 carbon atoms in the presence of a catalyst selected from the group consisting of organic acids, cationic ion exchangers, silica gels, layer silicates, inorganic acids or Lewis-acid-based catalysts. The specific oligo-α-olefins are distinguished by particularly high spreading power, by an improved sensory impression of the final cosmetic formulation and by particularly good stability in antiperspirant/deodorant formulations.
