Poly(acrylic acid) (PAA; trade name Carbomer) is a synthetic high-molecular-weight polymer of acrylic acid. The IUPAC name is poly(1-carboxyethylene). They may be homopolymers of acrylic acid or crosslinked with an allyl ether of pentaerythritol, allyl ether of sucrose, or allyl ether of propylene. In a water solution at neutral pH, PAA is an anionic polymer, i.e. many of the side chains of PAA will lose their protons and acquire a negative charge. This makes PAAs polyelectrolytes, with the ability to absorb and retain water and swell to many times their original volume.
Dry PAAs are sold as white, fluffy powders that are frequently used as gels in cosmetic and personal care products. Their role in cosmetics is to suspend solids in liquids, prevent emulsions from separating and control the consistency in the flow of cosmetics. Carbomer codes (910, 934, 940, 941, and 934P) are an indication of molecular weight and the specific components of the polymer. For many applications, PAAs are used in form of alkali metal or ammonium salts, e.g. sodium polyacrylate. In the dry powder form, the positively charged sodium ions are bound to the polyacrylate, however, in aqueous solutions, the sodium ions can dissociate. Instead of an organized polymer chain, this leads to a swollen gel that can absorb a high amount of water.
Polyacrylic acid and its derivatives are used in disposable diapers, ion exchange resins, adhesives, and detergents. Detergents are often copolymers of acrylic acid that can be used in both zeolites and phosphates in washing powder formulations. They are also popular as a thickening, dispersing, suspending, and emulsifying agent in pharmaceuticals, cosmetics, and paints. Cross-linked polyacrylic acid has also been used in the processing of household products, including floor cleaners. Acrylic acid is also the main component of Superabsorbent Polymers (SAPs), cross-linked polyacrylates that can absorb and retain more than 100 times of their own weight in liquid. PAA may inactivate the antiseptic chlorhexidine gluconate.
The neutralized polyacrylic acid gels are suitable to obtain biocompatible matrices for medical applications such as gels for skincare or skin disease treatment products. PAA films can be deposited on orthopedic implants to protect them from corrosion. Crosslinked hydrogels of AA and gelatin have also been used as medical glue, which has a high bonding strength.
