摘要:
Unsaturated coconut and/or palm nut fatty alcohols having an iodine number in the range from 65 to 85, which essentially comprise unsaturated fatty alcohols and mixtures of saturated fatty alcohols of the formula (I): R1OH (I) in which R1 is a saturated or unsaturated, linear or branched alkyl radical having 12 to 20 carbon atoms, obtainable by fractionating coconut and/or palm nut fatty acid methyl esters to obtain a fraction containing predominantly C16-C18 portions, fractionating the C16-C18 fatty acid methyl ester fraction into a predominantly saturated distillate and a predominantly unsaturated bottom product, and hydrogenating the bottom product with retention of the double bonds to give the corresponding alcohols; are disclosed.
摘要:
The disclosed invention relates to sterol and/or stanol esters of ethercarboxylic acids corresponding to general formula (I):R(OAlk)nOCH2COOH, in which R is a C1-50 alkyl, alkenyl and/or alkylphenyl group derived from an alcohol, OAlk stands for ring-opened ethylene oxide, propylene oxide and/or butylene oxide units and n is a number of 0 to 100, and to a process for making said sterols and stanols. The inventive sterols and stanols have a number of uses, including as steroid precursors, as emulsifiers and as a hypocholesterolaemic active component of foods.

摘要:
A process for making branched, substantially unsaturated ester oils involving: (a) providing an unsaturated C16-22 fatty acid; (b) dimerizing the unsaturated C16-22 fatty acid; (c) removing a monomer fraction accumulating during dimerization, the monomer fraction containing branched, substantially unsaturated fatty acids; (d) converting the branched, substantially unsaturated fatty acids contained in the monomer fraction into corresponding branched, substantially unsaturated fatty acid methyl esters having double bonds; (e) hydrogenating the branched, substantially unsaturated fatty acid methyl esters, with their double bonds intact, to form corresponding branched, substantially unsaturated fatty alcohols; and (f) esterifying the branched, substantially unsaturated fatty alcohols to form the branched, substantially unsaturated ester oils.
摘要:
Described is the use of oleophilic monomeric and/or oligomeric diesters of carbonic acid with the same or different oil-soluble and ecologically compatible mono-functional and optionally polyfunctional alcohols as a component of oil-based or water-based drilling fluids and other fluid drill-hole treatment agents. The invention in one embodiment comprises oil-based fluids, and particularly inverted fluids of the W/O type, which in the continuous phase at least in part contain oleophilic carbonic acid diesters. In a further important embodiment the invention relates to water-based emulsion fluids which in the dispersed oil phase at least in part contain said oleophilic carbonic acid diesters. The invention further comprises drill-hole treatment agents, and especially drilling fluids of the above-mentioned types, the continuous or dispersed oil phases of which, respectively, consist of oleophilic carbonic acid disasters or contain said ester type in admixture with other ecologically compatible oil mixing components. Preferred mixing components for a use in combination which the carbonic acid diesters are appropriate carboxylic acid ester oils, oleophilic alcohols and/or oleophilic ethers.
摘要:
Methods of use of carbonic acid esters corresponding to general formula I: ##STR1## in which R.sup.1 is an alkyl radical derived from an aliphatic saturated primary alcohol containing 1 to 22 carbon atoms and R.sup.2 is an alkyl radical derived from an aliphatic, saturated primary alcohol containing 1 to 8 carbon atoms and/or has the same meaning as R.sup.1 and n is a number of 2 to 20 while m is 0 or has the same meaning as n, as foam control agents for the sugar beet or potato-processing food industry and/or in fermentation processes are provided. In the industrial processing of sugar-containing plant juices, as carried out on an industrial scale in the case of sugar beet, particular difficulties are caused by excessive foaming in the defecation units, during transport of the beet, in the diffusors and in the carbonizing tanks and before the evaporators, thus, use of the esters in these processes is advantageous. Other areas of use include the production of potato products, such as chips or French fries, in the production of baker's yeast using molasses or other industrial fermentation processes, such as the production of medicaments, to reduce foaming to a level which does not interfere with the industrial production process.
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.
