Quaternium-83

Quaternium-83 (CAS 91723-55-6), also marketed as Varisoft 445, is a conditioning quaternary ammonium compound used in personal care formulations. It deposits onto hair and skin surfaces to reduce friction. This compound improves manageability and delivers a smooth, soft feel. In rinse-off hair conditioners and treatment masks, it adsorbs onto negatively charged, damaged hair fibers to reduce combing force and static.

Leave-in conditioning sprays and detangling formulations rely on it for lightweight, non-greasy conditioning performance without excessive buildup. It provides excellent results in professional hair care applications. Skin-conditioning emulsions incorporate it as an emulsifier and surface modifier to improve spreadability and tactile feel. It also functions as a substantive conditioning agent in various cleansing systems.

This material is particularly effective where standard cationic conditioners are neutralized by anionic surfactants. It maintains its performance profile across a wide range of cosmetic and personal care pH levels. Quaternium-83 is typically supplied as a liquid or paste, often in a solvent or isopropanol base to aid handling. It is available in technical and cosmetic grades suited to personal care manufacturing.

Buyers should confirm active content concentration with suppliers, as commercial forms vary in solids content. Proper storage and handling ensure the stability and efficacy of the ingredient in final products.
