Hydroxypropyl Tetrahydropyrantriol

Hydroxypropyl Tetrahydropyrantriol (CAS 439685-79-7), also known commercially as C-beta-D-xylopyranoside-2-hydroxypropane, is a synthetic xyloside derivative used in cosmetic formulations. It is valued for its ability to stimulate the skin's natural glycosaminoglycan synthesis.

It functions as a bioactive moisturizing agent rather than a simple humectant, targeting the dermal matrix to support skin firmness. This ingredient works at a structural level to maintain hydration and support the skin's underlying architecture.

In prestige skincare, it is incorporated into anti-aging serums and creams where the goal is to boost hyaluronic acid production. It also aids in the synthesis of chondroitin sulfate within the skin layers to improve overall density.

Day and night moisturizers targeting loss of elasticity use it as an active ingredient at low inclusion levels. It also appears in targeted eye contour treatments and neck creams where dense hydration and structural support are the primary objectives.

Pharmaceutical topical preparations exploring dermal matrix support represent an emerging application area for this ingredient. Its unique mechanism of action makes it a versatile choice for advanced dermatological research and development.

The product is typically supplied as an aqueous solution, with concentration levels standardized for cosmetic active use. Cosmetic-grade material is the primary commercial specification available to formulators in the industry.

Packaging is generally suited to small-to-mid volume procurement, reflecting its use as a high-value active rather than a bulk commodity. This ensures the stability and integrity of the chemical during transport and storage for manufacturers.
