As a cationic surfactant, BTMS Conditioning Emulsifier performs excellently in hair care products. Hair often becomes static and tangled due to daily combing and environmental factors, but its cationic properties neutralize the negative charge on the hair surface, effectively reducing static and making hair smooth and manageable. In conditioners, hair masks, and shampoos, it penetrates the hair shaft, fills in damaged areas of the cuticles, provides long-lasting nourishment, making hair soft and shiny, improving combability, and reducing breakage risk, especially suitable for dry and damaged hair.

In skincare products, the emulsifying function of BTMS Conditioning Emulsifier is crucial. It promotes the uniform mixing of oil and water phases, forming a stable emulsion system, which ensures the stability of textures in products such as lotions, creams, and body lotions. When applying skincare products containing this ingredient, one can distinctly feel the soft and moisturizing skin sensation it provides. It forms a thin protective film on the skin surface, locks in moisture, enhances skin barrier function, and replenishes moisture for different skin types, improving roughness and making the skin smooth and delicate. Moreover, it can adjust the viscosity of the product, ensuring that the product is neither too runny nor too thick when applied, thereby optimizing the user experience.
