Kostol TMC-25

Kostol TMC-25 is a versatile, cationic emulsifier designed for hair and skin care formulations. Its cationic chemistry provides superior adhesion to hair and skin, offering conditioning, detangling, static control, and frizz reduction in hair care products, and skin conditioning with a silky, non-greasy after-feel in skin care products. This emulsifier creates stable, white to off-white emulsions with a medium break and smooth sensory profile. It is PEG-free, sulfate-free, and manufactured without volatile materials, ensuring safety in lab and production environments while meeting regulatory requirements in markets prohibiting such additives.

Kostol TMC-25 is highly compatible with a wide range of cosmetic ingredients and can be used in both leave-on and wash-off systems, including shampoos, conditioners, creams, lotions, shave products, hair masks, and styling products. It is approved for use with leading clean beauty brands such as Clean at Sephora, Credo Beauty, and Whole Foods Premium Body Care. The recommended emulsifier-to-oil ratio is 1:4 to ensure proper balance and stability in formulations.

Formulators should note that cationic emulsifiers like Kostol TMC-25 are typically incompatible with anionic ingredients, such as certain acrylate copolymers, xanthan gums, and CMC thickeners. Coordinate with your regulatory team to ensure compliance with regional guidelines. The Koster Keunen formulation team has developed a variety of personal care formulas, including hair conditioners, masks, and skin care products, showcasing the versatility of Kostol TMC-25.
