TEGO FILMSTAR BST1(Behenoyl Polyglyceryl-3/Hydrogenated Dilinoleic Acid/Sebacic Acid Crosspolymer)
TEGO FILMSTAR BST1 is a bio-based, cruelty-free, vegan suitable, biodegradable film former. It is extracted from plant-based materials, including rapeseed/canola (Brassica) and castor (Ricinus communis). It forms a uniform protective layer due to its hydrophobic structure, enhancing UV filter efficiency without affecting texture, sensory properties, or formulation stability—even in lightweight sprays and fluid formulas.
- It enables high SPF with fewer UV filters, supporting sustainable and microplastic-free formulations
- It provides excellent emulsion compatibility and dermatological benefits such as soothing and skin barrier repair.
- It offers a next-generation, eco-conscious solution for high-performance sun care products.
- It is recommended for both classic sun protection and daily SPF skincare.
- TEGO FILMSTAR BST1 is suitable for a broad range of formulation including lotions, creams, sprays, fluids and sticks.
