Hydroxyethylcellulose (Hydroxyethylcellulose)

Hydroxyethylcellulose is a non-ionic, cellulose-derived polymer widely used in cosmetic formulations as a thickener, stabilizer, and rheology modifier for water-based systems. It builds viscosity and improves flow control, helping create clear to slightly hazy gels with a smooth, non-tacky spread and good slip. By enhancing suspension, it can help keep insoluble particles, exfoliants, or pigments evenly dispersed, and it supports overall formula stability by reducing phase separation and improving texture consistency over time. Hydroxyethylcellulose is commonly found in facial cleansers, shampoos, shower gels, micellar and toner-like formats, serums, gels, masks, and styling products, where it contributes to a refined sensorial profile and controlled viscosity. Use level and performance are formulation-dependent and typically optimized with pH, electrolyte content, and the broader surfactant or emulsifier system to achieve the desired clarity, yield value, and application feel.
