Description

Aqua SF-1 is a high-performance acrylates copolymer designed for use as a thickening, film-forming, stabilizing, and rheology-modifying agent in cosmetic and personal care formulations. It is typically supplied as a white to off-white free-flowing powder or as a pre-neutralized dispersion, depending on grade and supplier.

When dispersed in water and neutralized, Aqua SF-1 forms clear to slightly hazy gels with excellent viscosity build, smooth flow behavior, and strong formulation stability. It is widely valued for delivering lightweight texture, enhanced sensory feel, and long-lasting film formation.
