Polyacrylic Acid (PAA) is a synthetic, high-molecular-weight polymer produced by the polymerization of acrylic acid. It contains numerous carboxylic acid groups along its polymer backbone, giving it useful thickening, viscosity-modifying, dispersing, suspending and water-absorbing properties.
Polyacrylic Acid is available in different molecular-weight and cross-linking grades. Depending on the grade and intended application, it can be used as a pharmaceutical excipient, formulation aid, rheology modifier, suspending agent and polymeric material.
Swapnroop Pharma manufactures and supplies Polyacrylic Acid in India for qualified pharmaceutical, nutraceutical, cosmetic, chemical and specialty formulation applications.
Polyacrylic Acid and related acrylic acid polymers can provide important functional properties in pharmaceutical formulations.
Depending on grade, its functions may include:
Polyacrylic Acid can be incorporated into selected oral, topical and semi-solid formulations where viscosity, suspension stability or gel formation is required.
Its carboxylic acid groups can interact with water and other formulation components, allowing the polymer to modify rheology and produce structured systems.
Applications may include:
Polyacrylic Acid is a broad polymer family. Carbomers are highly cross-linked polyacrylic-acid-type polymers commonly used as pharmaceutical excipients.
Therefore, Polyacrylic Acid and Carbomer should not automatically be treated as identical products. The exact polymer grade, molecular weight, cross-linking and regulatory designation should be specified in the product documentation.
Polyacrylic Acid has the general repeating-unit structure:
[–CH₂–CH(COOH)–]ₙ
Its molecular weight varies according to the polymerization process and grade. Unlike a small molecule, it does not have one fixed molecular weight.
The material may be supplied as a white to off-white powder, granules or solid polymer, depending on molecular weight, concentration and grade.
Polyacrylic Acid is highly hydrophilic and can swell substantially in water. Its viscosity and rheological behavior are strongly affected by molecular weight, concentration and pH.
Swapnroop Pharma supplies Polyacrylic Acid for pharmaceutical and specialty formulation applications, with grade selection based on the customer's required polymer characteristics.
Important grade attributes may include:
Polyacrylic Acid should be stored in tightly closed, moisture-protective packaging in a cool, dry and clean environment.
The product should be protected from excessive moisture, heat and contamination. Storage requirements should follow the applicable SDS and approved product specification.
Depending on the grade and customer requirements, documentation may include:
