Import Acetyl Tetrapeptide-5 — Buy in wholesale FOB from Supplier in China

Acetyl Tetrapeptide-5 is a synthetic tetrapeptide with the molecular formula C14H24N8O5, supplied by Chengdu Youngshe Chem Co., Ltd as a lyophilised powder for cosmetic formulation. The peptide functions as an aquaporin inhibitor, modulating water transport across cell membranes to reduce oedema and improve skin hydration in topical applications. This ingredient is specifically positioned for premium eye cream formulations and broader anti-ageing skincare products targeting periorbital concerns.

The material is produced through solid-phase peptide synthesis, a standard method for cosmetic-grade peptides, with purification to achieve batch consistency and target purity levels typical for cosmetic peptide raw materials. The lyophilised form ensures stability during storage and transport, requiring reconstitution in aqueous or cosolvent systems prior to formulation. Typical cosmetic peptide specifications include purity by HPLC of 95% or higher, though buyers should request the Certificate of Analysis for each lot to confirm actual test results. The powder is generally soluble in water and common cosmetic solvents, with pH stability in the range typical for neutral to mildly acidic formulations.

Primary applications include eye creams targeting puffiness and dark circles, facial serums for hydration support, and anti-ageing creams where moisture retention is a formulated benefit. Buyers are typically contract manufacturers, private-label skincare brands, and R&D laboratories developing dermatological formulations. The supplier indicates bulk quantities are available, though exact MOQ, pricing, and lead time should be confirmed directly with Chengdu Youngshe Chem Co., Ltd. Standard cosmetic peptide documentation, including MSDS and COA, should be requested prior to purchase.

Chengdu Youngshe Chem Co., Ltd is located at 6, 23rd Floor, Building 1, No 666 Jitai Road, New and Hi-Tech Zone, Chengdu, Sichuan Province, China, postal code 610000. The company operates from a high-tech zone address, which in China typically indicates access to biotechnology and pharmaceutical development infrastructure, though the listing provides no specific details about manufacturing facility scale or in-house synthesis capabilities. The trust tier is classified as harbour, and the response rate shows 0.00 with zero average response hours, suggesting either a newly registered account or incomplete engagement metrics on the platform.

The supplier profile does not state year of establishment, number of employees, annual revenue, specific certifications held, or named clients. There is no mention of GMP compliance, ISO certification, or third-party audit status in the available data. Buyers should verify directly with Chengdu Youngshe Chem Co., Ltd whether the company performs peptide synthesis in-house or sources through partnerships, what analytical capabilities exist for batch release testing, and whether they provide regulatory support documentation such as cosmetic safety assessments or REACH registration status for EU buyers. The company's focus appears to be on cosmetic peptide raw materials for B2B supply, positioning it within the broader Chengdu biotechnology cluster.
