The mixture of alcohols consists essentially of (A) at least one C12 or C14 primary alcohol and (B) at least one C13 or C15 primary alcohol. The weight ratio of the even carbon number alcohols (A) to the odd carbon number alcohols (B) is from about 0.25:1 to about 4:1, preferably from about 0.5:1 to about 3:1. At least 70% by weight of each alcohol is linear and substantially all of the remainder of each alcohol is branched at the two carbon position. The compositions of this invention have unique properties in that they are substantially non-greasy, lack oiliness and greasiness, have low cloud points and pour points, have a bland odor, low toxicity, and are stable. The properties make such compositions useful as a vehicle or carrier, emollient or solubilizer for toiletry and cosmetic formulations, e.g., hair cream, hand cleaner, bath oil, suntan oil, brilliantine, anti-perspirants, perfumes and colognes, cold creams, electric pre-shave, eye and throat oil, fingernail polish, topical pharmaceutical ointments, lipsticks, stick rouge, skin lotions and creams, skin moisturizers, cleansing creams and after bath splash and lotions.Other References
