3. What Is Hydroxypropyl Tetrahydropyrantriol?
Hydroxypropyl Tetrahydropyrantriol is a sugar-derived cosmetic ingredient identified under CAS No. 439685-79-7. It is commonly used in skincare formulations as a functional cosmetic active to support skin conditioning, texture improvement, and formulation stability.
In the cosmetics industry, this ingredient is recognized for its good water solubility, formulation compatibility, and stability across a broad pH range, making it suitable for use in modern emulsions, serums, and creams. It is supplied as a raw material for industrial cosmetic manufacturing, not as a finished consumer product.
