New Biodegradable Rheology Agent

Solvay has introduced a new biodegradable rheology agent, Rheozan BLC, a natural and ready-to-use liquid polymer solution that delivers high suspension power in the home and personal care products, yet without any impact on the formulation viscosity.


“Solvay’s new Rheozan BLC combines the best of science and nature. It is an innovative and flexible ingredient that leverages the full power of biotechnology with beneficial functions and excellent sustainability credentials,” said Jean-Guy Le Helloco, Global Vice President, Home and Personal Care at Solvay. “This COSMOS-certified ingredient enables new formulation possibilities and addresses the market demand for biodegradable solutions, making it a win-win solution for formulators and consumers.”

Rheozan BLC is derived from grey biotechnology. Its synthesis is based on starch fermentation by carefully selected bacterial strains that generate very uniform cellulose fibers. When added to the home and personal care formulas, these nature-engineered fibres build a regular three-dimensional mesh, creating a highly effective suspension mechanism. It can suspend and stabilise visual cues such as pigments, natural exfoliating particles, perfume capsules, air bubbles, opacifier or emulsion, and insoluble agents such as zinc pyrithione or minerals.
