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

Trends and consumer expectations are shifting toward more naturally derived products. Formulators must develop high-performing products with advanced aesthetics, fewer synthetic chemicals and more eco-friendly materials.

“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-validated 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 home and personal care formulas, these nature-engineered fibers build a regular three-dimensional mesh, creating a highly effective suspension mechanism.
