Import Allantoin — Buy in Bulk from Supplier in China

Allantoin (CAS 97-59-6) is a heterocyclic compound derived from the oxidation of uric acid, commonly synthesised for cosmetic and pharmaceutical use. Hebei Tianao Technology Co., Ltd supplies this white crystalline powder with established application in skin-soothing formulations. The compound exhibits zero-order kinetics in topical delivery and maintains stability across a broad pH range, typically 4.0 to 9.0 in finished formulations. Standard cosmetic-grade allantoin carries a purity specification of 99.0% minimum on a dry basis, with loss on drying not exceeding 0.5% at 105 degrees Celsius. The material is odourless or nearly so, with a characteristic slightly bitter taste, and dissolves sparingly in cold water at approximately 0.5 g per 100 ml at 25 degrees Celsius.

Chemically, allantoin is 5-ureidohydantoin, a diureide of glyoxylic acid with the molecular formula C4H6N4O3 and molecular weight of 158.12 g per mol. Industrial production typically proceeds via oxidation of uric acid with alkaline potassium permanganate, or through acid-catalysed condensation of urea and glyoxylic acid. Cosmetic-grade material must meet heavy metal limits, typically lead below 10 ppm and arsenic below 2 ppm, with total bacterial count below 1000 CFU per gram and absence of specific pathogens. The material is non-comedogenic and exhibits very low sensitising potential, with a long history of safe use in leave-on and rinse-off products at concentrations up to 2.0%. Standard packaging for bulk pharmaceutical and cosmetic raw material is 25 kg net weight in fibre drums with polyethylene liner, though this supplier's exact packaging configuration should be confirmed directly.

Primary buyers include formulators of therapeutic moisturisers, anti-ageing serums, after-sun products, and nappy rash ointments, as well as manufacturers of oral care and wound healing dressings. Allantoin functions as a keratolytic agent at higher concentrations and as a cell proliferant and soothing agent at typical cosmetic levels of 0.2% to 0.5%. Regulatory status varies by market: it is listed in the EU Cosmetics Regulation inventory, permitted in China under the national standard for cosmetic ingredients, and generally recognised as safe for topical use in the United States. Buyers should verify Hebei Tianao Technology Co., Ltd's specific certificates of analysis, confirm whether material is synthetic or plant-derived, and establish exact lead times and Incoterms before committing to shipment.

Hebei Tianao Technology Co., Ltd is a chemical supplier located in China, classified within the imported supplier tier and harbour trust level on the marketplace where it lists allantoin. The company profile provides no response rate or average response time data, suggesting that direct communication channels may be untested or that enquiry volume has been limited. As a harbour-tier supplier,eliness signals are present but not strong, and buyers should conduct standard due diligence including requesting a current business licence, VAT registration certificate, and any available export authorisation before placing trial orders.

The listing offers allantoin for cosmetic and personal care applications but does not state specific production capacity, factory audit status, or in-house quality control capabilities. No ISO, GMP, or other certification numbers are provided in the source material, nor are specific MOQ, price, or lead time figures confirmed. The supplier mentions flexible order quantities and multiple packaging options, though exact configurations must be negotiated. Buyers should request a certificate of analysis for the specific batch, confirm whether material is synthetic or vegetable-derived, and verify storage and handling conditions prior to shipment.
