What is Carbomer Powder?
Carbomer is a high molecular polymer cross-linked by acrylic acid and allyl sucrose or allyl pentaerythritol. It was first produced by G00drich Company of the United States, and its trade name is Carbopol. This product is loose white powder, acidic, hygroscopic and special slightly smelly, soluble in water, ethanol, glycerin. The molecule contains 56% to 58% carboxyl groups, so it is weakly acidic. When carbomer is dispersed in water, due to the repulsion between the negative charges generated by the ionization of the carboxyl group, the curly polymer stretches and expands in volume. The pH of the 0.5% aqueous dispersion is 2.7-3.5. The 1% aqueous dispersion can be neutralized by alkaline substances to form a gel. Commonly used aqueous dispersions have a concentration of 0.1% to 3.0%.
Function
1. Carbomer has the function of protecting the skin. Because it has a certain affinity with the skin, adding it to skin care products can reduce the irritation and damage of irritating substances to the skin and mucous membranes.
2. Carbomer has anti-ultraviolet effect, which can enhance the skin's resistance to ultraviolet rays and reduce the damage of ultraviolet rays to the skin.
3. Carbomer can also reduce the viscosity. Carbomer has a certain degree of looseness, and it is a slightly acidic substance with particularly strong dilution.
The main functions of carbomer are thickening, suspending, emulsifying, etc., and can be used as gelling agent, adhesive, coating material, rheology modifier (wetting agent, lubricant, suspending agent, Stabilizer), etc., are widely used, especially have greater application prospects in new drug delivery systems. It has been widely used at home and abroad.
