A cosmetic composition containing a dermatologically acceptable carrier or vehicle and certain essential oils as a preservative. The essential oil provides antimicrobial assurance against Apergillus niger, Candida albicans, Staphylococcus aureus and Pseudomonas aeruginosa. A method of preparing the preserved cosmetic composition is also described.

Preservation of cosmetic compositions

A permanent waving process is disclosed in which an essential oil is incorporated into hair fibers. The incorporated of the essential oil into the hair fiber not only provides capacity to remove bad odors resulting from freshly permanent waved hair but also gives to the hair a supple and smooth feeling. The essential oil is incorporated in the oxidizing or neutralizing solution of the permanent waving process. The essential oils employed are those containing at least one component, ingredient or constituent having an ethylenically unsaturated bond, i.e. ##STR1##

Process of incorporating essential oils into hair fibers and permanent

An opacifier composition for use in permanent waving compositions and neutralizer compositions associated therewith. The opacifier composition is an aqueous emulsion containing: (a) methyl ester of hydrogenated rosin acids, (b) an alkylene glycol such as octylene glycol, and (c) a mixture of nonionic surfactants, such as the polyoxyethylene ethers of fatty alcohols, for example lauryl alcohol. The use of the opacifier composition eliminates or minimizes hair breakage which occurs with other opacifier systems such as those employing latex emulsions.
