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.

摘要:
The invention is directed to a cosmetic composition which contains at least one poly-α-olefin produced by subjecting at least one primary alcohol to dehydrating polymerization at a temperature of 60° C. to 340° C. in the presence of acidic alumino layer silicates. The primary alcohol is an alcohol from the group of unsaturated monofunctional alcohols, branched monofunctional alcohols and difunctional alcohols. The poly-α-olefin is a high-spreading oil component which imparts an almost instantaneous and relatively long-lasting feeling of smoothness to the skin and has good dermatological compatibility.

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.

Compounds of the formula (I): wherein each of R1-R12 is independently hydrogen or a linear C1-20 alkyl group each of A1 and A2 is a 1, 2 or 3 ring carbon atom wherein A1 is substituted by R9 and R10 and A2 is substituted by R11 and R12; and wherein at least one of R1-R12 is a linear alkyl group having from 1 to 20 carbon atoms are emollients for use in cosmetics, lubricants and pharmaceutical preparations.
摘要:
A process for producing unsaturated fatty compounds having improved low-temperature properties bya) splitting lauric oils into fatty acids and glycerol,b) subjecting the fatty acids to fractional crystallization to obtain a fraction of unsaturated fatty acids, andc) hydrogenating the unsaturated fatty acids, optionally after converting the unsaturated fatty acids into their lower alkyl esters, to form unsaturated fatty alcohols having an iodine value of from about 85 to about 100.
