Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate is often used in a blend with other ingredients such as emollient squalane and film-forming polymers to enhance stability, texture, and create stick formulas. EWG's Skin Deep® rates Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate as a moderate hazard ingredient due to concerns about its persistence and bioaccumulation in the environment and its potential to be an environmental toxin. The ingredient is also classified as a low human health priority by Environment Canada. Versastique™ Clear M 5T is a multi-functional material that provides a better way to formulate through simplified creation of functional and esthetic solid stick applications. With translucent and clear stick properties, Versastique is ideal for natural, mineral and synthetic ingredients in cosmetics, personal care, skin care, sun care and health care products.
