New Lanolin Acid Quaternary Salts for use in Hair Treatment Preparations
Justin P. McCarthy , Lee R. Mores , Mitchell L. Schlossman

ABSTRACT

Synopsis

The action of QUATERNARY AMMONIUM SURFACTANTS on HAIR has been studied for many years. Several of the characteristics, which are important in formulating with these SALTS, are dependent upon their molecular configuration. In this paper, lanolin compounds which essentially comprise QUATERNARY DERIVATIVES (QUATS) of LANOLIN ACIDS are described. The preparation of a derivative of lanolin consisting essentially of the reaction product of a lanolin acid and a specific diamine followed by quaternization is outlined. The chemical and physical properties of quats are briefly reviewed and compared with emphasis on these new lanolin acid derivatives, and their chemistry and processing is highlighted. Each of these quaternary salts was incorporated into hair conditioning preparations and evaluated on human hair.
