I. Basic Information (Foreign Trade/Chemical Standards)
English: (S)-Pro-xylane; S-Pro-xylane
Chinese: S-Pro-xylane; (S)-Hydroxypropyltetrahydropyrantriol
CAS No.: 439685-79-7 (Same number as racemic Pro-xylane, marked with S-configuration)
Molecular Formula: C₈H₁₆O₅
Molecular Weight: 192.21
Appearance: White to off-white crystalline powder
Solubility: Easily soluble in water, ethanol, and propylene glycol; stable in aqueous solution
Configuration: S-configuration (β-S stereospecific), significantly higher activity than the racemic form
II. Core Advantages (Exclusive Selling Points of S-Configuration)
High stereoselectivity, stronger activity
The S-configuration is the only active conformation, with biological activity 1.5–2 times that of racemic Pro-xylane, resulting in a lower effective concentration and more pronounced effects.
The Golden Ingredients for Dermal Matrix Reconstruction: Targets and stimulates the synthesis of glycosaminoglycans (GAGs), hyaluronic acid, and type IV/VII collagen, strengthening the dermal-epidermal junction (DEJ) for fuller, firmer, and more elastic skin.
Gentle and Non-Irritating, Suitable for Sensitive Skin: Non-acidic, non-retinol, non-photosensitive, non-peeling, suitable for long-term anti-aging for all skin types.
Green Chemical Source: Derived from beech xylose, the synthesis process is environmentally friendly and biodegradable.
Excellent Formula Compatibility: Works synergistically with peptides, hyaluronic acid, AA2G, astaxanthin, PQQ, and other ingredients without conflict.
