What is it?
- The Carbomers are large molecules prepared from relatively small chemical compounds called monomers. The monomers used to make Carbomer polymers are acrylic acid and polyalkenyl polyethers.
- The Carbomers are all chemically similar, differing from each other in molecular weight and viscosity. Carbomers have the ability to absorb and retain water, and these polymers can swell to many times their original volume.
- On a label of a cosmetic or personal care product, the name Carbomer may be associated with a number such as 910, 934, 940, 941 and 934P. These numbers are an indication of molecular weight and the specific components of the polymer.
- Carbomer is a term used for a series of polymers primarily made from acrylic acid. The Carbomers are white, fluffy powders but are frequently used as gels in cosmetics and personal care products. Carbomers can be found in a wide variety of product types including skin, hair, nail, and makeup products, as well as dentifrices.
Why is it used in cosmetics and personal care products?
- The Carbomers help to distribute or suspend an insoluble solid in a liquid. They are also used to keep emulsions from separating into their oil and liquid components. Carbomers are often used to control the consistency and flow of cosmetics and personal care products.
