Description of Hydroxypropyl Tetrahydropyran Triol
Pro-Xylane is a synthetic skincare ingredient chemically known as Hydroxypropyl Tetrahydropyran Triol (CAS 439685-79-7). It was developed through green chemistry processes starting from xylose, a natural wood sugar, making it both effective and environmentally conscious. The molecule is designed to mimic glycosaminoglycans (GAGs), which are essential components of the skin’s extracellular matrix.

Application of Hydroxypropyl Tetrahydropyran Triol (Pro-Xylane)
1. Anti-Aging & Wrinkle Reduction
Pro-Xylane addresses multiple signs of aging through comprehensive dermal matrix support:
- Reduces appearance of fine lines and wrinkles
- Improves skin firmness and elasticity
- Enhances skin density for a more youthful appearance
- Provides cumulative benefits with continued use
2. Enhanced Hydration & Moisture Retention
By stimulating natural hyaluronic acid production and improving skin barrier function:
- Increases skin hydration levels by up to 28%
- Improves transepidermal water loss (TEWL) measurements
- Creates a plumping effect for smoother skin texture
- Supports skin’s natural moisture barrier
3. Skin Firming & Lifting
The reinforcement of the dermal-epidermal junction provides noticeable firming benefits:
- Improves skin elasticity by up to 9%
- Creates a lifting effect for facial contours
- Enhances skin resilience against environmental stressors
- Reduces sagging and loss of skin tone

Synthesis of ultra-fine tantalum carbide powders by a combinational method of sol–gel and spark plasma sintering
Abstract: A variety of methods have been reported for the preparation of TaC powders, such as self-propagating-high-temperature synthesis (SHS) [6], molten salt synthesis [7], metal thermal reduction [8], [9], sol-gel process [10], [11], [12], liquid precursor conversion method [13], [14] and chemical vapor deposition (CVD) [15]. Among these methods, the sol–gel process is an effective method to obtain ultra-fine TaC powders because of the intimate contact of the reagents at a molecular or colloidal scale [10]. Yan et al. [11] synthesized TaC powders with a particle size of about 30 nm at 1500 °C using tantalum alkoxide, allyl-functional novolac resin and acetylacetone as raw materials.
