  • Hair Care (Primary Use):

    • Substantivity: Hair strands develop a negative charge (anionic) when damaged or wet. The positively charged Steartrimonium Methosulfate is strongly attracted to and binds to these sites, forming a thin, lubricating film.

    • Detangling & Smoothing: This film smooths the hair cuticle, reduces static flyaway, and dramatically improves wet and dry combability.

    • Softness & Manageability: Steartrimonium Methosulfate (STME 85) imparts a soft, silky feel to hair.

    • Moisturization: Helps hair retain moisture.

    • Common Products: Cream rinses, conditioners, deep treatments, leave-in products, and 2-in-1 shampoos (where it is often compatibilized with anionic surfactants).

  • Skin Care:

    • Steartrimonium Methosulfate (STME 85) acts as an emollient and skin conditioning agent, providing a soft, smooth afterfeel in lotions and creams.
