Derived from grey biotechnology, the liquid polymer is in line with current trends and consumer expectations that are shifting toward more naturally derived products. Formulators therefore 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-certified ingredient enables new formulation possibilities and addresses the market demand for biodegradable solutions, making it a win-win solution for formulators and consumers."

Starch fermentation

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

Solvay’s Rheozan BLC belongs to a new generation of biotechnology-based ingredients that can revolutionize the chemical industry, harnessing the power of nature to combine higher performance with more safety and sustainability toward a more circular economy,” said the company in a release.
