Strong Tyrosinase Inhibition with Remarkable Brightening Effect
We adopt precision organic synthesis and multi-stage recrystallization to produce high-purity phenylethyl resorcinol. Independent lab tests show its tyrosinase inhibitory activity is over 30 times higher than kojic acid. Each batch undergoes HPLC testing to control purity, heavy metals and microbial limits, and full COA documents are provided to meet international cosmetic raw material safety standards for factory inspection.
Ultra-Low Irritation, Safe for Sensitive Skin Formulations
Multi-layer membrane filtration removes unreacted toxic intermediates, with heavy metal content controlled below 5ppm. Unlike hydroquinone and high-concentration kojic acid, Symwhite rarely triggers redness or stinging. The whole production workshop follows GMP cosmetic management systems, covering 7,900 square meters of aseptic space to guarantee safe raw materials for long-term external skincare use.
Stable Chemical Properties Adaptable to Multiple Production Conditions
This fine off-white crystalline powder features low hygroscopicity and uniform particle size, free of agglomeration during mixing, cold emulsification and filling. It maintains stable whitening activity under routine cosmetic processing temperatures without discoloration or efficacy loss. It mixes well with tranexamic acid, niacinamide and plant extracts without chemical incompatibility.
Large Production Capacity & Year-Round Stable Bulk Inventory
Our annual Symwhite output reaches 120 tons, and permanent bulk stock is kept all year round. After order confirmation, ready goods can be delivered within 3–7 working days to prevent clients’ production shutdown caused by raw material shortages. We accept flexible order volumes from small 1kg sample bags to 25kg industrial drums for diverse brand demands.
Factory Direct Wholesale Price & Complete Export Supporting Documents
As a direct manufacturer without intermediate dealers, we offer tiered preferential bulk prices for mass orders. We provide full export documents including COA, cosmetic safety assessment reports and free sales certificates, greatly simplifying overseas customs clearance and local cosmetic brand registration procedures for global buyers.
Spot Fading & Brightening Facial Serums & Essences
Phenylethyl Resorcinol is the core active ingredient for dark spot correction serums and brightening essences. It targets melanin deposits to lighten sun spots, acne marks and dull complexion. Its stable powder property fits cold mixing production, suitable for daily concentrated whitening care products for all skin types including sensitive skin.
Even-Tone Moisturizing Creams & Facial Lotions
Manufacturers blend this Symwhite powder with niacinamide, vitamin C derivatives and plant soothing extracts into daily whitening face creams. It gradually evens overall skin tone while maintaining skin hydration. The low-irritation formula supports long-term continuous use without damaging the skin barrier, matching clean-label skincare trends.
Professional Post-Sun Repair & Brightening Mask Products
This whitening powder is added into after-sun soothing masks and exfoliating brightening sheet masks. It inhibits UV-induced melanin overproduction to prevent skin darkening after sun exposure. It disperses evenly with mask base materials and retains full activity during low-temperature mask production processes.
