Product Overview
This is a high-purity botanical extract obtained through targeted extraction and spray-drying processes. The standardized active ingredient (Salicin) content is **25%**. Salicin is a natural prodrug found in willow bark, which is metabolized in the body into active compounds with soothing, anti-inflammatory, and analgesic effects. It is often referred to as "natural aspirin." Compared to synthetic salicylic acid, this product is significantly milder and less irritating.

Key Functions & Characteristics
1. Skincare (Cosmetic Ingredient)
- Pore Unclogging: Provides keratolytic action to help remove dead skin cells that clog pores, improving blackheads, whiteheads, and acne-prone skin.
- Soothing & Anti-inflammatory: Effectively inhibits the synthesis of inflammatory mediators (e.g., prostaglandins), helping to calm inflamed acne and folliculitis.
- Anti-aging Synergy: Promotes epidermal cell renewal, improving skin smoothness and radiance when combined with other active ingredients.
- Mild Alternative: Unlike direct salicylic acid (BHA), salicin requires enzymatic conversion in the skin to release its active form, resulting in significantly lower irritation — ideal for formulating gentle anti-acne products.
2. Hair Care
- Anti-dandruff & Itch Relief: Inhibits *Malassezia* yeast on the scalp, regulates the scalp microbiome, reduces dandruff, and relieves itching.
3. Health Supplements / Pharmaceuticals (Oral grade requires separate validation)
- When taken orally, provides systemic anti-inflammatory, analgesic, and antipyretic effects, commonly used to relieve joint pain, headaches, and mild fever.
Key Advantages
1. Precise Concentration: The 25% standardized content offers an optimal cost-performance balance — more effective than lower concentrations and more economical/formulatable than higher concentrations (e.g., 50% or 98%).
2. Easy Dissolution: Optimized processing ensures good dispersibility even in cold water, simplifying manufacturing.
3. Dual Identity: Suitable for "acid peel" cosmetic claims while retaining the mild, natural botanical extract positioning.
4. Stability: Excellent powder stability when stored in a cool, dry, dark place (24-month shelf life); resistant to oxidative discoloration.
