Quaternium-83

Quaternium-83 (CAS 91723-55-6), also marketed as Varisoft 445, is a conditioning quaternary ammonium compound used in personal care formulations.

Where is Quaternium-83 used?

• Hair care: deposits onto hair and skin surfaces to reduce friction
• Rinse-off conditioners and treatment masks: adsorbs onto negatively charged, damaged hair fibers to reduce combing force and static
• Leave-in conditioning sprays and detanglers: lightweight, non-greasy conditioning without excessive buildup
• Skin-conditioning emulsions: emulsifier and surface modifier for spreadability and tactile feel
• Cleansing systems: substantive conditioning agent
• It remains effective where standard cationic conditioners are neutralized by anionic surfactants.

Good to know: Buyers should confirm active content concentration with suppliers, as commercial forms vary in solids content.

Commercial specifications

• Liquid or paste, often in a solvent or isopropanol base
• Active content concentration varies in solids content
