Bacterial Cellulose-Carboxymethyl Cellulose (BC:CMC) dry formulation as stabilizer and texturizing agent for surfactant-free cosmetic formulations

Generic cosmetic creams (oil-in-water emulsions) were prepared using dry Bacterial Cellulose and Carboxymethyl (BC:CMC) to study the possibility of partially or completely replacing surfactants, while ensuring a long-term stability required organoleptic characteristics. BC:CMC was benchmarked against two hydrocolloidal Avicel products (PC-591 PC-611), commonly used as thickeners stabilizing aids in cosmetics production. The emulsions then characterized regarding storage stability, rheology, texture microscopic features. full replacement 5.5 % surfactants with only 0.75 consistently showed similar results those obtained namely concerning viscosity texture. Although producing larger oil droplets, provided for very effective stabilization through Pickering effect by structuring continuous phase. more tested (PC-591) higher concentration (1.5 %) achieve rheological profile but ineffective phase surfactant-free formulation adopted protocol. By matches strong market need since both end users manufacturers increasingly seek natural ingredients formulations.
