Polyacrylic Acid, commercially known as , is a versatile polymer derived from acrylic acid. This high-performance material serves as an effective thickening, suspending, dispersing, and emulsifying agent across multiple industries.

Poly(acrylic acid) (PAA) is a polymer with the formula (CH2-CHCO2H)n. In water solutions at neutral pH, PAA functions as an anionic polymer, where many side chains lose protons and acquire negative charges. This characteristic makes partially or wholly deprotonated PAAs effective polyelectrolytes with exceptional water absorption and retention capabilities, allowing them to swell to many times their original volume.

• Cosmetics & Personal Care: Clear gels, hydro-alcoholic gels, lotions, creams, styling gel, facial moisturizer, sunscreen, shampoo, anti-aging treatment, eye cream, cleansers, and scrubs
• Pharmaceutical: Suspending agents, gel bases, emulsifiers, binding agents, artificial tears, and antiglaucoma treatments
• Healthcare: Key component in BufferGel formulation for microbicide and spermicide applications, providing protection against HIV and sexually transmitted diseases
• Industrial Specialties: Textile printing, printing inks, emulsion-based lubricants, polishes, waxes, paints, waterproof and oil-proof coatings

This ingredient's versatility makes it indispensable across cosmetic and industrial applications where precise viscosity control, suspension stability, and water retention are critical requirements.
