PHENYLETHYL RESORCINOL
1. Basic information
Chemical name : 4-(1-phenethyl)-1, 3-hydroquinone
Trade name : SymWhite 377 (commonly found in cosmetics)
Chemical formula : C₁₄H₁₄O₂
CAS No. Youdaoplaceholder0:85-27-8
Appearance : White to pale brown/beige crystalline powder
Molecular weight : 214.26 g/mol
2. Physical and chemical properties
Characteristic parameter values
Melting point 78-82°C
Solubility Slightly soluble in water (3.85g/L at 20 ° C) readily soluble in propylene glycol, polar oils and organic solvents (such as chloroform, ethyl acetate)
Density 1.171 g/cm³
Stability should be stored away from light, sealed, and in an inert gas environment
3. Core efficacy
Effective whitening
Mechanism of action : Strongly inhibits tyrosinase activity (a key enzyme in melanin synthesis), reducing melanin production.
Comparison of effects : 0.5% concentration has better whitening effect than 1% kojic acid (untested by light exposure).
Antioxidant & anti-aging
Eliminate free radicals and delay photoaging of the skin.
Safety
Non-carcinogenic, clinically proven high stability;
Some people may be allergic and need to be tested in advance.
4. Application areas and specifications
Areas of use :
Whitening skin care products (essence, lotion, cream), freckle removal and anti-aging cosmetics.
Regulatory Restrictions (China) :
Limited : ≤0.5%;
Use Limitation : Only for "whitening specialty products", not for ordinary cosmetics.
5. Production and supply
Synthesis process : Produced by Friedel-Crafts alkylation of resorcinol and styrene, with an optimized yield of up to 88%.
Product specifications :
Purity ≥99%;
Packaging: 1kg/25kg sealed, light-protected packaging.
Storage requirements : Cool, dry, inert atmosphere.
6. Market Positioning
Advantages : Highly active, low irritation whitening ingredients, known as the "Hermes of whitening";
Prospects : Derived from the natural ingredient silver pine, it combines innovation and efficacy.
Note: The actual application should strictly follow the cosmetic regulations of each country, and individual skin tolerance should be evaluated.
