Carbomer, which has a variety of cross-linked acrylic polymers and copolymers, is one of the basic components of many daily necessities. Carbomer can be seen in a series of product components from cosmetics and personal care products to printing ink, coating adhesive, industrial products and so on. Since the development and production of Carbomer, many industries have relied on carbomer to increase the viscosity of products, forming gelatin, stabilizing emulsion and suspended particles. In addition, it has the characteristics of improving product texture and realizing the long-term stability of shelf products. Kapom is also known as "the best friend of the formula designer".

Carbomer powder

The main component of carbomer is acrylic acid (polyacrylic acid), which is synthesized by free radical precipitation polymerization in organic solvent. The solvent in this process makes the monomer, initiator and other additives soluble in the reaction medium, but the resulting polymer product is insoluble in. According to records, "benzene" was previously used as the preferred process solvent for carbomer synthesis, but "benzene" is unfavorable to health and safety problems. Now, an alternative solvent system (such as a mixture of ethyl acetate and cyclohexane) is used instead of benzene.

A preparation method of carbomer

1. Acrylic acid and a small amount of tape and potassium carbonate (K2CO3) were dissolved in ethyl acetate or cyclohexane cosolvent（ K2CO3 is added with acrylic acid to neutralize a small part (usually ≤ 3%) of acrylic acid groups and to help promote the precipitation of the resulting polymer in the cosolvent system.)

2. The mixture was heated to 50. D egree. C. in a nitrogen atmosphere and a peroxide initiator such as di (2-ethylhexyl) peroxydicarbonate (pre dissolved in a cosolvent) was slowly added to the reaction vessel within 6 hours.

3. With the progress of polymerization, insoluble carbomer products precipitate from the solvent to form the slurry of carbomer particles in the solvent.

4. After the reaction is completed, Carbomer is separated from the slurry and the polymer solid is dried to produce carbomer product in powder form.
