More Information
Summary:NEW MATERIAL:A compound of formulaI(R is 9-21C aliphatic hydrocarbon group). EXAMPLE:1,5-Dimethyl-2-isopentylhexyl myristate. USE:Useful as a component in cosmetics or drugs for external use in direct contact with the skin or an oily component incorporated with an oil or emulsion, e.g. a medicine, in the liquid state at room temperatue, and having a lower cloud point than expected from the molecular weight without giving the irritation to the skin surface even in continuous use, and having improved stability in air for the ester of a saturated fatty acid. PROCESS:1,5-Dimethyl-2-isopentylhexanol of formula II or a reactive derivative thereof and a 10-22C fatty acid or a reactive derivative thereof, e.g. an acid halide, are reacted with a dehydrohalogenating agent, e.g. pyridine, in a solvent, e.g. benzene, at 50-100 deg.C under heating and stirring to give the aimed compound of formulaI.
