Import Acetyl Tetrapeptide-33 — Buy in wholesale FOB from Supplier in China

Acetyl Tetrapeptide-33 is a synthetic cosmetic peptide with molecular formula C20H32N8O6 and molecular weight approximately 480.52 g/mol, supplied by Chengdu Youngshe Chem Co., Ltd from their facility in Chengdu, Sichuan province. The material is offered at greater than 95% purity as quantified by HPLC analysis, a standard analytical threshold for cosmetic-grade peptide actives destined for premium skincare formulations. This tetrapeptide is typically incorporated at use levels between 50 and 500 parts per million, a concentration range that balances biological activity with formulation stability and cost efficiency in finished goods.

The peptide consists of four amino acid residues in acetylated form, a common structural modification that enhances skin penetration and metabolic stability compared to unmodified analogues. Synthetic production via solid-phase peptide synthesis (SPPS) is the standard industry method, yielding consistent batch-to-batch reproducibility that formulators require for regulatory compliance and claim substantiation. The material is classified as a cosmetic-grade active rather than a pharmaceutical ingredient, which affects its regulatory pathway and documentation requirements in most jurisdictions. Typical storage conditions specify refrigerated temperatures, usually 2-8 degrees Celsius, to prevent hydrolysis and maintain potency throughout the product shelf life.

Primary applications include anti-aging serums, firming creams, and specialised dermatological products targeting collagen protection and skin elasticity restoration. Buyers are predominantly B2B cosmetic manufacturers, contract formulation houses, and ingredient distributors serving the personal care sector. Trade terms commonly offered include FOB and CIF, with letter of credit and telegraphic transfer as standard payment instruments. Minimum order quantities vary according to pack size and destination. Buyers should confirm current lead times, exact MOQ thresholds, and certificate of analysis availability directly with Chengdu Youngshe Chem Co., Ltd before placing orders.
