摘要
nanoemulsion with coconut oil by temperature phase inversion method for preparing compositions the invention, belonging to the cosmetics sector, more specifically cosmetics or similar personal care products, characterized by the special physical form of nanoemulsions containing esters of carboxylic fatty acids and use of quaternary ammonium compounds, refers to the coconut oil nanoemulsion preferably for hair treatment. in a jacketed reactor with a mechanical stirrer the heated aqueous phase is added in an auxiliary tank at a temperature of 40 to 100 ºc, over the heated oil phase directly in the main reactor at a temperature of 4 to 100 ºc, stirred at 30 to 1000 rpm for 3 180 minutes. then, the mixture is cooled in a cooling bath at a temperature of 5 ± 2 ºc with gentle agitation until reaching a temperature of 22 ± 2 ºc, in order to obtain ehl (hydrophilic-lipophilic balance) from 8 to 12. a the aqueous phase consists of 45 to 96% water, preferably 70 to 80%, alkyl trimethyl ammonium chloride (50% quaternary ammonium) from 0.01 to 3%, preferably 1%, and the oil phase consisting of monooleate of ethoxylated sorbitan (tween 80); 1 to 15%, preferably 1 to 15%, of sorbitan monooleate (span 80), preferably 1 to 15%, coconut oil 2 to 40%, preferably 6 and 10%, (percentages expressed by mass) with the product obtained then, compositions can be prepared containing nanoemulsified coconut oil.
