Description

CarboMer FD21

CarboMer FD21 is a high-performance crosslinked Polyacrylic acid polymer designed for fast hydration, efficient thickening, and excellent stabilization in pharmaceutical, cosmetic, and personal care formulations. It provides high clarity, smooth gel texture, and robust rheological control, making it an ideal choice for modern gel systems, hydroalcoholic formulations, and topical products requiring rapid processing and consistent performance.
CarboMer FD21 appears as a white, free-flowing, hygroscopic powder that disperses quickly in water. Upon neutralization, it forms clear, medium-to-high viscosity gels with pseudoplastic flow behavior. This shear-thinning profile improves ease of application while maintaining viscosity and suspension capability at rest.
In pharmaceutical, cosmetic, and personal care applications, CarboMer FD21 is used in:
• Fast-hydrating topical gels, serums, and dermatological products
• Hydroalcoholic gels for sanitizers, antiseptics, and active-loaded solutions
• Ophthalmic and mucosal formulations requiring clarity and gentle texture
• Creams, lotions, and emulsion systems that require viscosity stability
• Oral care gels and viscous rinse formulations
• Controlled-release drug delivery systems and transdermal platforms
CarboMer FD21 offers excellent compatibility with surfactants, alcohols, electrolytes, and active pharmaceutical ingredients. Its rapid hydration capability enhances processing efficiency, while its consistent rheology supports formulation stability across a range of temperatures and environmental conditions.
CarboMer supplies CarboMer FD21 with control over viscosity, crosslink density, particle size distribution, residual monomers, moisture content, and microbial quality. The material is produced under rigorous quality systems suitable for regulated pharmaceutical and cosmetic manufacturing.
The material is packaged in sealed, moisture-resistant, tamper-evident containers. Available in laboratory, pilot, and commercial-scale quantities. Documentation includes Certificate of Analysis (CoA), Safety Data Sheet (SDS), and full traceability.
Each batch is tested for identity (IR), viscosity after neutralization, loss on drying, pH (after neutralization), residual solvents, and microbial limits. CarboMer offers detailed formulation guidance to ensure optimal hydration, dispersion, and neutralization for stable, high-performance gels and emulsions.
As with all CarboMer rheology modifiers, CarboMer FD21 is backed by global supply assurance, stringent quality control, and technical expertise to support the development of safe, effective, and aesthetically refined formulations.
