Ultra-high Efficiency Whitening & Spot-lighteningAs a potent competitive inhibitor of tyrosinase, its molecular structure is similar to tyrosine. It can bind to the active site of tyrosinase in advance, blocking the melanin synthesis pathway at the source. The whitening efficiency is 32 times higher than that of arbutin and 210 times higher than that of kojic acid. At a 1% concentration, the inhibition rate of tyrosinase reaches over 90%, and it has significant fading effects on sun spots, chloasma, freckles and post-inflammatory hyperpigmentation.
Multi-functional Skin Care & High SafetyBesides whitening, it also has strong antioxidant properties, which can scavenge free radicals, reduce UV-induced skin damage and delay skin aging. Compared with traditional whitening ingredients such as hydroquinone, it has no cytotoxicity, low skin irritation, and is suitable for sensitive skin (a skin patch test is recommended before use). It has excellent light and heat resistance, remains stable in a pH range of 4.0-8.0, and is not easy to decompose or discolor, ensuring a long shelf life of finished products.
Good Formulation Compatibility & Wide ApplicationIt is soluble in ethanol, propylene glycol, butylene glycol and other organic solvents, and slightly soluble in water (solubility 265mg/L at 25℃). It can be compounded with niacinamide, vitamin C, hyaluronic acid, ceramides and other mainstream skincare ingredients to achieve synergistic effects. The recommended addition amount in cosmetics is 0.1%-0.5% (not exceeding 1%). It is widely used in high-end whitening serums, spot-lightening creams, facial masks and post-medical aesthetic repair products.
Independent R&D & Customization ServiceOur professional R&D team has optimized the production process, using self-developed solid superacid catalyst system to increase the reaction conversion rate by 30%, reduce by-products and improve product purity. We can provide customized services such as microencapsulation and water-soluble formulations according to customer needs, solve formulation stability problems, and provide one-stop technical support for product development.
Sufficient Stock & Efficient DeliveryWe keep a regular inventory of 500kg of 99% cosmetic-grade 4-(α-Methylbenzyl)resorcinol powder. Gram-level samples can be shipped on the same day, kilogram-level trial orders and ton-level bulk orders can be arranged for logistics within 72 hours. We support sea freight, air freight and other international transportation methods, provide professional moisture-proof and light-proof packaging, and ensure product quality during long-distance transportation. Complete export documents including COA, MSDS and customs clearance materials are available to ensure smooth foreign trade customs clearance.
Strict Quality Control & Favorable Cooperation PolicyEvery batch of products undergoes 5 rounds of quality inspection including raw material testing, in-process control, purity analysis, heavy metal detection and microbial limit test. Heavy metal content is less than 5ppm, and total microbial count is ≤100CFU/g. For long-term cooperative customers, we offer free sample testing, factory inspection arrangements, preferential bulk prices and priority production scheduling rights to achieve mutual benefit and win-win results.
Dosage Control: The optimal addition amount in cosmetics is 0.1%-0.5%. Excessive addition will not enhance the whitening effect but may increase skin irritation risk. It is recommended to use with sunscreen products to maximize the whitening and spot-lightening effect.
Storage Conditions: Seal and store in a cool, dry and well-ventilated warehouse, away from direct sunlight and high temperature and humidity environments. The shelf life can reach 24 months under proper storage conditions.
