Abstract
Dicyclohexylalkanes, their preparation, cosmetic and pharmaceutical formulations containing these compounds, and their use in these formulations as oil components for cosmetic and pharmaceutical purposes.
Claims9
In a cosmetic or pharmaceutical formulation containing an oil component in combination with cosmetically or pharmaceutically acceptable ingredients, the improvement wherein the oil component contains a spreadably effective amount of a dicyclohexylalkane of the formula I ##STR2## where x, y, and z are each from 0 to 24 and the sum x+y+z is from 4 to 24.
In a cosmetic hair care formulation which contains a film-former and an oil component, the improvement wherein the oil component contains a mixture of dicyclohexylalkanes of formula (I) ##STR3## in which the alkyl chain in formula (I) contains a total of 10 to 14 carbons and the cyclohexyl groups are randomly distributed in the chains on secondary carbon atoms thereof, and in which x, y, and z may each be zero, provided that their sum is at least 6, the dicyclohexylalkane having an extinction coefficient of about 0.01 at 275 nm and a pour point of -49.degree. C., the dicyclohexane being present in amount of 0.1 to 3.0% by weight of the total formulation.
