Description

CarboMer 351

CarboMer 351 is a high-purity crosslinked Polyacrylic Acid polymer designed for use as a rheology modifier, stabilizer, and thickening agent in pharmaceutical, personal care, and cosmetic formulations. It produces medium-to-high viscosity gels with excellent clarity, spreadability, and stability, making it well suited for aqueous and hydroalcoholic systems.
CarboMer 351 appears as a white, lightweight, hygroscopic powder that rapidly hydrates when dispersed in water. When neutralized, it forms smooth, transparent gels with pseudoplastic flow behavior, providing ease of application while maintaining viscosity and suspension capability at rest.
In pharmaceutical, cosmetic, and personal care applications, CarboMer 351 is used in:
• Topical gels, lotions, and creams requiring clear and stable viscosity
• Hydroalcoholic systems including sanitizers and antiseptic gels
• Ophthalmic and mucosal formulations that demand clarity and gentle texture
• Oral care products such as gels and viscous rinses
• Emulsion systems where uniform thickening and stabilization are required
• Controlled-release matrices and transdermal delivery platforms
CarboMer 351 provides excellent compatibility with a variety of actives and excipients. Its ability to stabilize emulsions, suspend particulates, and provide smooth, elegant rheology makes it a versatile polymer for both pharmaceutical and cosmetic formulations. It delivers consistent performance in both low- and high-shear processing environments.
CarboMer supplies CarboMer 351 with control over viscosity, crosslink density, particle size, residual monomers, moisture content, and microbial purity. The material meets stringent internal quality specifications and is suitable for regulated product development and commercial manufacturing.
The material is packaged in sealed, moisture-protective, tamper-evident containers. Available in laboratory, pilot, and commercial-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and complete traceability.
Each batch is tested for identity (IR), viscosity after neutralization, loss on drying, pH (after neutralization), residual solvents, and microbial limits. CarboMer provides technical and formulation support to ensure optimal dispersion, hydration, and neutralization procedures for achieving desired gel properties.
As with all CarboMer rheology modifiers, CarboMer 351 is backed by secure global supply, stringent quality control, and expert formulation guidance to support safe, stable, and high-performance product development.
