Quaternium-70

Quaternium-70 (CAS 68921-83-5), also known as Stearamidopropyl dimethyl (myristyl acetate) ammonium chloride, is a quaternary ammonium compound used as a conditioning surfactant. It delivers surface charge modification and emulsification across a range of rinse-off and leave-on product formats. In hair care, it deposits on negatively charged hair fiber to reduce static.

This ingredient improves combability and enhances softness in conditioners and conditioning shampoos. Skin care formulators incorporate it into lotions and creams where controlled emulsification is required. It is also utilized where surface wetting is required alongside a conditioning effect. In fabric care and home cleaning products, it functions as a softening and wetting agent for substrates.

The compound improves substrate feel and product spreadability. Its dual fatty acid character, stearamide and myristyl ester, supports compatibility with both rinse-off conditioner bases and emulsified systems. Quaternium-70 is typically supplied as a paste or waxy solid, reflecting its high fatty chain content. It is available in technical and cosmetic grades suited to personal care manufacturing specifications.

Buyers should confirm active content and solvent or carrier composition with the supplier. Commercial forms may vary in concentration depending on the specific application and formulation needs.
