Abstract
In making compounds to increase the water vapour porosity of the fat component of cosmetic preparations (see Group VI) 2-methyl dodecanol is converted into its bromide by treatment with 48% HBr and reacted with sodium malonic ester to give 2-methyldodecyl malonic acid ester which is then saponified to give 2-methyl-dodecyl malonic acid which, on heating at 10 mm. pressure, decarboxylates to 4-methyl-myristic acid. This may be converted to the ethyl ester by boiling with an ethanol-toluene-mixture, the ester being reduced with lithium aluminium hydroxide to 4-methyl tetradecanol which is converted to the bromide which, with sodium malonic ester gives 4-methyl tetradecyl-1-malonic ester which, on saponification and decarboxylation gives-6-methyl palmitic acid from which, as above, 6-methyl hexadecanol may be produced and, as above, through the bromide and 6-methyl hexadecyl-1-malonic ester, and saponification and decarboxylation, give 8-methylstearic acid. This may be converted to its ethyl ester which is reduced to give 8-methyl octadecanol. Dihydro citronellol myristinate is prepared by reacting myristic acid chloride with dihydro citronellol in pyridine.ALSO:The water vapour porosity of the fat component of cosmetics is increased by adding thereto 1 to 10% by weight of a branched chain aliphatic compound having 5 to 20 carbon atoms in the open chain and having a branch chain containing less than 3 carbon atoms spaced at least 1 carbon atom from the end carbon atoms in the open chain and bring an alcohol or an acid or a straight chain ester of said alcohol or acid with said straight chain having 5 to 20 carbon atoms. The fat component may be the conventional fatty materials used in cosmetic creams, lotions and salves, such as lanolin, petrolatum, vegetable oils, waxes and fatty acids. Lists of acids alcohols, and esters are given and examples of the preparation of 4-methyl myristic acid, 6-methyl palmitic acid, 8-methyl stearic acid: 8-methyl octadecanol, 6-methyl hexadecanol: dihydro citroneleol myristate are given.
