Description
Poly(acrylic acid) is either a white powder or a viscous liquid, depending on its molecular weight. Soluble in water, form a colloidal solution, with good chemical stability. Store in a cool, dry place away from strong alkalis and oxidants.
Characteristics

Acrylic acid is a colorless liquid with a distinctive acrid odor. Flash point 130°F. Boiling point 286°F. Freezing point 53°F. Corrosive to metals and tissue. Prolonged exposure to fire or heat can cause polymerization. If polymerization takes place in a closed container, violent rupture may occur. The inhibitor (usually hydroquinone) greatly reduces the tendency to polymerize.

Fireproof. Separated from strong oxidants, strong bases, strong acids and food and feedstuffs. Keep in the dark. Store only if stabilized. Store in an area without drain or sewer access. Storage conditions may vary according to the type of inhibitor used. Refer to the manufacturer's instructions for proper storage conditions. See Notes.
Carbomers are discolored by resorcinol and are incompatible with phenol, cationic polymers, strong acids, and high levels of electrolytes. Certain antimicrobial adjuvants should also be avoided or used at low levels. Trace levels of iron and other transition metals can catalytically degrade carbomer dispersions. Certain amino-functional actives form complexes with carbomer Carbomers also form pH-dependent complexes with certain polymeric excipients.

Poly(acrylic acid) Use and Manufacturing
It is prepared by initiating polymerization of acrylic acid in the presence of ammonium persulfate.
Poly(acrylic acid) (PAA or Carbomer) is generic name for synthetic high molecular weight polymers of acrylic acid. They may be homopolymers of acrylic acid, crosslinked with an allyl ether 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 t
Drug Function and Efficacy
This product is a broad-spectrum antifungal drug. Its mechanism of action is to inhibit the synthesis of fungal cell membranes and affect their metabolic processes. It has antibacterial effects on dermatophytes, Candida, etc., and also has certain therapeutic effects on certain Gram-positive cocci.
