What is poly acrylic acid used for?
Polyacrylic acid is considered to be a first mucoadhesive polymer and the protonated form at an acidic pH is responsible for mucoadhesion. It is used as artificial tears to treat dry eye syndrome. Polyacrylic acid forms the hydrogen bond between its –COOH groups and sialic –COOH groups of the mucin glycoprotein.

What type of polymer is Carbopol?
crosslinked polyacrylic acid polymer
Carbopol® 676 polymer is a highly crosslinked polyacrylic acid polymer. It has short flow characteristics and relatively high viscosity performance.
What is Carbopol made of?
Carbopol 934 is cross-linked with allyl sucrose and polymerized in benzene. Carbopol 71, 971, and 974 are cross-linked with allylpentaerythritol and polymerized in ethyl acetate. Carbomer polymers contain 56%–68% of carboxylic acid (–COOH) groups and 0.75%–2% of cross-linking agents.
Is Carbopol toxic?
The Carbopol® polymers, like other high molecular weight polymers, demonstrate a low toxic and irritation potential based on their physical and chemical properties.
What is the difference between carbomer and Carbopol?
What is the substitute of Carbopol?
Amigel® is an alternative to carbomer and other synthetic agents of petrochemical origin. Made of 100% polysaccharide of natural origin with exceptional gelling and thickening properties, Amigel® is an incomparable stabilizing agent for the formulation of emulsions and suspensions.
