Import Acetyl Tetrapeptide-9 — Buy in wholesale FOB from Supplier in China

Acetyl Tetrapeptide-9 is a synthetic cosmetic peptide with molecular formula C22H33N7O9 and molecular weight of 539.54 g/mol, supplied by Zhenyibio Technology Inc. from their facility in Xi'an, Shaanxi Province, China. The material is a white crystalline powder with certified purity of 99%, registered under CAS number 928006-50-2. It is manufactured to enterprise standard and holds INCI approval for use in cosmetic formulations. The peptide functions by stimulating synthesis of type I collagen and lumican, a small leucine-rich proteoglycan that organises collagen fibrils into functional networks.

The mechanism centres on lumican-mediated collagen fibre organisation. Lumican binds to collagen fibrils and regulates their diameter, spacing, and overall architecture. Acetyl Tetrapeptide-9 strengthens this connection, improving the skin's resistance to mechanical traction and increasing dermal firmness. Typical cosmetic peptide batches require storage in sealed containers away from moisture and light, with standard shelf life of*REDACTED* two years from manufacture when kept at 2-8°C. The powder is soluble in water and common cosmetic solvents, permitting formulation into aqueous systems at typical use concentrations of 0.001-0.01%.

Cosmetic formulators incorporate this peptide into anti-ageing serums, firming creams, and body lotions targeting loss of elasticity. The primary buyers are contract manufacturers and brand owners in the skincare sector, particularly those developing products for mature skin or post-pregnancy body care. When sourcing from Zhenyibio Technology Inc., buyers should confirm batch-specific CoA data, peptide content by HPLC, and microbial limits. The supplier's harbour trust tier and zero recorded response rate mean direct enquiry is essential to establish communication channels and negotiate specific terms.

Zhenyibio Technology Inc. operates from No.29 Kejiliulu in the Gaoxin District of Xi'an City, Shaanxi Province, China, placing it within the Xi'an National Civil Aerospace Industrial Base zone known for biotechnology and pharmaceutical clustering. The company holds harbour trust tier status on the sourcing platform, which indicates basic verification of business licence and operational presence rather than advanced audit or inspection history. The address provided is a specific street location in a recognised high-tech development zone, not a residential or virtual office address.

The supplier profile shows a response rate of 0.00% with zero average response hours recorded, which suggests either a new listing, dormant account, or data collection gap rather than necessarily poor performance. No information is provided about manufacturing facility scale, GMP certification, R&D headcount, annual revenue, or named domestic or international clients. Buyers must independently verify production capacity, whether the peptide is manufactured in-house or sourced from a third-party API facility, keel, and whether the company holds any cosmetic ingredient GMP or ISO 22716 certification. The listing positions Zhenyibio as a supplier of cosmetic active ingredients for B2B export, with Acetyl Tetrapeptide-9 representing one peptide in what may be a broader catalogue.
