摘要:
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:
Reaction products of maleic anhydride and/or itaconic anhydride with one or more olefinically-unsaturated fatty compounds as compatibilizers for cellulose/plastic composites.
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 new sun protection compositions with improved water resistance which are distinguished by the fact that they have an effective content of diol dimer fatty acid esters and, more particularly, dimer diol dimer fatty acid esters.
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.
摘要:
A polyalkylene glycol having the general formula:HO--[R--O--].sub.n Hin which n has a value of at least 2 and R is an alkylene radical containing at least 20 carbon atoms is provided. Preferred polyalkylene glycols have an alkylene radical which is a branched alkylene radical containing at least 10 carbon atoms in the main chain and a degree of polymerization such that n is from 4 to 7. The polyalkylene glycol is prepared by the acid-catalyzed polycondensation of a monomeric alkylene glycol at elevated temperature.
摘要:
A process for the production of cellulose/plastic composites, characterized in that cellulose, more particularly wood, a plastic, more particularly polyvinyl chloride, a compatibilizer containing carboxylic anhydride groups, and a catalyst from the group of heteroaromatic compounds are combined, mixed together, preferably at a temperature in the range from 50° to 130° C., and the dry blend obtained is subsequently heated to a temperature above the melting temperature of the plastic, subjected to the desired shaping process, and allowed to cool.
摘要:
Fuel compositions containing fuels and glycerol are disclosed. The addition of glycerol increases the combustion value of the fuels, and enables combustion to take place more uniformly and with less slag formation. The use of glycerol for improving the combustion value and combustion efficiency of liquid or solid fuels is thus also disclosed.
摘要:
Processes for producing conjugated linoleic acid are described which comprise: (a) isomerizing a linoleic acid lower alkyl ester in the presence of an alkali metal alcoholate to form a conjugated linoleic acid lower alkyl ester; (b) saponifying the conjugated linoleic acid lower alkyl ester in the presence of an aqueous lye to form a saponification product; and (c) neutralizing the saponification product with phosphoric acid.
