Abstract
Novel compositions of matter consisting of amido propyl dialkyl amino beta hydroxy ethyl ammonium halides of mink oil have been found to be excellent emollients having surprisingly good hair conditioning properties. They are prepared for example by reacting either ethylene chlorohydrin or ethylene bromohydrin in a medium of water and propylene glycol, with an amide obtained by reacting, under anhydrous conditions, mink oil with either dimethylaminopropylamine or diethylaminopropylamine using an alkaline catalyst such as sodium hydroxide.
