The mixture acts as a binding agent (ensures the desired cohesion of powdery, powdery or creamy products, prevents solids and liquid components from segregating), combability aid (reduces or prevents tangling of the hair due to changes or damage on the hair surface, thus improving combability), Emulsion stabilizer (supports the emulsion formation and improves the resistance and durability of emulsions), film former (forms a film on skin, hair or nails when applied), antistatic agent (reduces static charges by neutralizing the electrical charge on the surface, for example of hair) and as hair fixative.
