Description
Cosmetic grade montmorillonite benonite clay:
Cosmetic grade montmorillonite is a kind of colloidal product which is prepared by purification, modification and modification of trioctahedral smectite and special dioctahedral montmorillonite. Its highly hydrophilic property makes it form a non Newtonian liquid thixotropic gel in water or alcohols and high polarity cleaning agents such as glycerol and sorbitol. It has excellent expansibility, colloid dispersion, suspension, thickening and thixotropy in water, and is an excellent anti settling agent for waterborne systems. In cosmetics instead of sodium carboxymethyl cellulose (CMC), it can improve the smoothness, stripiness and stability of the paste. As a component of cosmetics, montmorillonite is used to produce natural ecological moisturizing cosmetics. It has the properties of decontamination, detoxification, antipruritic, beauty and moisturizing.

Mechanism of Action:
Montmorillonite can form a layer of mucosal protective barrier on the skin surface to reduce the evaporation of skin moisture; at the same time, it can form an organic complex with other components in cosmetics to prolong the action time of drugs on the skin surface, so as to play a synergistic effect.
