D-Cycloserine
D-Cycloserine, supplied by Zhenyibio Technology Inc., is a cosmetic-grade fine chemical with the molecular formula C3H6N2O2 and a molecular weight of 102.09 g/mol. This off-white powder has a minimum purity of 99%, verified by HPLC testing, and is identified by the CAS number 68-41-7. The product is the D-isomer form of 4-Amino-3-isoxazolidinone, a compound recognised for its stability and solubility in aqueous formulations.
The material is primarily used as an active ingredient in advanced skin care formulations, particularly those targeting anti-aging and skin-barrier support. Its fine chemical grade ensures low impurity levels, which is critical for cosmetic applications where consistency and safety are paramount. Typical industry standards for such amino acid derivatives include a moisture content below 1% and a heavy metal content within pharmacopoeial limits, though these values should be confirmed with the supplier for this specific batch.
Formulators in the premium cosmetics sector source D-Cycloserine for its ability to enhance product performance in creams, serums, and lotions. The product is packaged in bulk quantities suitable for international export, and buyers should verify compatibility with their manufacturing processes. Common applications include amino acid infusions for hydration and cold creams, where its wettability and stability improve texture and efficacy.

Sourcing D-Cycloserine from Zhenyibio Technology Inc. - China Import Guide
Before ordering D-Cycloserine from Zhenyibio Technology Inc., verify the batch-specific certificate of analysis to confirm purity, moisture content, and heavy metal levels. Request documentation for HPLC testing methods and ensure the product meets the 99% minimum purity threshold required for cosmetic applications. Cross-check the CAS number and molecular formula to avoid misidentification.
For logistics, confirm whether the supplier offers FOB or CIF terms, as these will impact shipping costs and responsibility for freight. Lead times for bulk orders should be clarified, particularly if your production schedule is time-sensitive. Packaging compatibility with international transport regulations, such as IATA for air freight, should also be addressed to avoid delays at customs.
Quality checks should include visual inspection of the off-white powder for consistency in color and texture, as well as laboratory testing for purity and contaminants. Arrange for pre-shipment inspection if possible, and ensure all documentation, including the CoA and material safety data sheet (MSDS), is provided in English. This will facilitate compliance with import regulations in your country and streamline the customs clearance process.
