Polyoxyl 15 Hydroxystearate is widely used in the pharmaceutical and cosmetic industries as a solubilizer and emulsifier. In pharmaceuticals, it helps improve the solubility of poorly water-soluble drugs, enhancing their bioavailability and effectiveness. It is commonly found in injectable formulations, oral liquids, and topical creams, where it stabilizes the mixture of oil and water-based ingredients. In cosmetics, it is used to create smooth, stable emulsions in products like lotions, creams, and serums, ensuring even distribution of active ingredients and improving texture. Its non-irritating nature makes it suitable for sensitive skin applications. Additionally, it aids in the delivery of active compounds, enhancing the performance of skincare and personal care products.
