Application

• Hair Care Products: In hair dyes and perming agents, it serves as a dispersant and affinity agent to enhance the durability of the color. In shampoos and hair conditioners, it acts as an excellent surfactant and opacifier,improving the stability of the foam. In gel water, elastin, setting spray and so on, it serves as film forming and setting agent to provide high gloss, lasting and stable setting effect.

• Skin Care Products: In creams, it has a dispersing and stabilizing effect as well as a thickening effect, which can make the emulsifying system disperse evenly and remain stable without precipitation after long-term storage. In vanishing creams and sunscreens, it can enhance the moisturizing and lubricating effects. In facial masks, it has the functions of moisturizing and accelerating the penetration of the mask ingredients. In sun protection cosmetics, it can improve the rheological properties and help with the dissolution and dispersion of the sunscreens.

• Color Cosmetics: In beauty cosmetics such as eye shadows and mascaras, it can reduce the irritation of pigments to the skin.

• Other Products: In shaving creams, it can promote the softening of beards and increase the lubricating function; in toothpastes, it is used as a thickening agent.
