Yinherb Lab High Quality Pro-Xylane Powder CAS. 439685-79-7 99% Purity Min
Generic Name: Hydroxypropyl Tetrahydropyrantriol
CAS Number: 439685-79-7
Molecular Formula: C₈H₁₆O₅
Molecular Weight: 192.21 Da (exact calculated value)
Chemical Classification: Synthetic sugar derivative (xylose-based tetrahydropyran ring derivative)
Structural Core: Prepared by chemical modification of natural xylose (extracted from beech wood), forming a polyol structure containing a tetrahydropyran ring. The molecule has 3 hydroxyl groups (-OH) and 1 hydroxypropyl (-CH₂CH(OH)CH₃) substituent.
Synthesis Features: Produced via a two-step green synthesis process using water as solvent, with no toxic by-products. The product is biodegradable, complying with environmental standards.
Appearance: Colorless to pale yellow transparent viscous liquid, or white crystalline powder at room temperature (varies with purity and concentration).
Solubility: Highly soluble in polar solvents such as water, propylene glycol and glycerin; slightly soluble in ethanol; insoluble in non-polar solvents like oils and fats.
Stability: Excellent stability within the pH range of 3.0–8.0 (compatible with most skincare formulations), heat-resistant (no decomposition under short-term heating at ≤80℃), non-oxidizable, and well-compatible with other active skincare ingredients (e.g., vitamin C, hyaluronic acid).
Purity Requirement: Cosmetic-grade products typically have a purity of ≥98% (tested by HPLC), while industrial-grade products have a purity of ≥95%.
What is Pro-Xylane Powder?
Pro-Xylane Powder (CAS 439685-79-7, ≥98% HPLC) is a patented anti-aging active derived from natural beech wood xylose, developed by L'Oréal. As a unique C-glycoside, it powerfully stimulates GAGs and collagen synthesis, reinforcing skin matrix structure, improving firmness and elasticity, and reducing wrinkles. Gentle yet effective, it's ideal for sensitive skin and high-end anti-aging formulations.
Core Features
Natural xylose-derived C-glycoside with deep anti-aging & firming efficacy;
high water solubility & skin penetration; biodegradable, non-toxic, low irritation; compatible with most cosmetic actives (retinol, vitamin C, peptides);
stable in wide pH range (3–8);
improves skin texture, reduces wrinkles, restores plumpness.
Pro-Xylane Powder Mechanism of Action and Additional Efficacy
Anti-aging and wrinkle reduction: It can activate the synthesis of glycosaminoglycans (GAGs) in skin fibroblasts. These substances are important components of the skin's extracellular matrix and can promote the regeneration of type IV and VII collagen. This strengthens the connection between the dermis and the epidermis, enhances skin firmness and elasticity, and thereby fades fine lines and wrinkles. In vitro and in vivo tests have shown that it can improve skin quality by 17%.
Moisturizing and barrier repair: It can promote the skin to produce hyaluronic acid which is good at locking water. Meanwhile, the glycosaminoglycans it stimulates can form a colloidal structure that stores water, reducing skin moisture loss. In addition, it can promote the construction of skin proteoglycans, enhance the compactness of skin cells, and help repair the damaged skin barrier, making the skin smoother and more delicate.
Pro-Xylane Powder Application
Cosmetics field: It is a star ingredient in high-end anti-aging skin-care products. It is widely added to essences, creams, eye creams and other products. For example, L'Oréal's Revitalift Laser X3 series uses it as a core active ingredient with a 3% dosage.
Other industrial fields: It can be used as a film-forming additive in water-based coatings to optimize the flexibility and adhesion of the coating film; in the textile industry, it can be used as a softener or hydrophilic finishing agent for textiles to improve the softness and hydrophilicity of fabrics; it can also be used as an auxiliary component of surfactants in chemical industry to adjust the formula of emulsions and detergents.
