Compatibility
Works well with:
Cetrimonium Chloride Behentrimonium Chloride Cetyl Alcohol Dimethicone Panthenol Hydrolyzed Keratin
Use caution with:
Anionic surfactants at high concentrations
Amodimethicone carries a positive charge due to its amino groups and can form complexes or lose efficacy when combined with high levels of anionic surfactants. It is typically co-formulated with a nonionic or cationic surfactant (such as Trideceth-12 and Cetrimonium Chloride) to aid dispersion in aqueous systems. Compatibility with anionic ingredients should be tested at intended use concentrations.
Formulation notes
Amodimethicone is an amino-functional silicone that selectively deposits onto damaged, high-charge areas of the hair fiber, providing targeted conditioning, smoothing, and repair. It forms a flexible, substantive film that reduces friction, enhances shine, and improves combability without excessive buildup. Because it is not self-emulsifying in water, it is typically supplied as a pre-emulsified blend or requires a suitable surfactant system to disperse evenly in rinse-off and leave-on hair care formulas.
