LANXESS has launched Cosmelin, a new line of readily biodegradable esters for the cosmetics and personal care industry. The products target makers of skin care, hair care, sun care and decorative cosmetics.
The esters meet the OECD 301 standard for ready biodegradability. They are designed as functional substitutes for cyclomethicone and dimethicone, two silicone compounds widely used in cosmetics. According to the company, the esters degrade faster and more completely in the environment after use.
The range works in silicone-containing and silicone-free formulations. In silicone-free products, it can serve as a high-performance alternative to silicone. Textures run from very light and fast-spreading to rich and film-forming. The company says the esters are designed for low irritation and low comedogenicity, which makes them suitable for sensitive skin.
Applications vary by segment. In skin care, the esters provide moisturization without heaviness and can support the skin barrier. In sun care, they dissolve organic UV filters well and form water-resistant, lightweight films that do not leave a white cast. In color cosmetics, they aid pigment dispersion and allow glossy or matte finishes. In hair care, they reduce friction, add shine and help smooth the cuticle.
The portfolio spans monoesters, diesters, polyol esters and trimellitates. Three products are named so far. Cosmelin 5131 is isononyl isononanoate, with an ultra-light, powdery feel. Cosmelin 5145 is cetyl ethylhexanoate, which gives a rich, silky finish. Cosmelin 5141 is triisotridecyl trimellitate, aimed at high gloss and long-lasting makeup.
Vince Patram, Head of Global Marketing Lubricant Additives at LANXESS, said the line responds to rising demand for clean beauty and eco-friendly ingredients. He said it does so without sacrificing the skin feel consumers expect from premium products.
