Import Acetyl Tetrapeptide-11 — Buy in wholesale FOB from Supplier in China

Acetyl Tetrapeptide-11 from Zhenyibio Technology Inc. is a synthetic cosmetic peptide with established INCI nomenclature, molecular formula C27H38N4O7 and molecular weight 530.61, supplied as a 99% pure white powder under enterprise standard. The Xi'an-based company specifies this material for anti-wrinkle and anti-aging applications where skin adhesion, tightness and elasticity are targeted. The peptide's mechanism as a skin conditioner positions it within the premium active ingredient segment of cosmetic ingredient portfolios. Buyers should confirm batch-specific CoA data, as the 99% purity figure requires analytical substantiation for each lot.

The enterprise standard under which this material is produced indicates an in-house or industry-association specification rather than a national pharmacopoeial or internationally harmonised standard. Typical industry practice for cosmetic peptides at this purity level employs solid-phase peptide synthesis (SPPS) with acetyl capping at the N-terminus, followed by preparative HPLC purification and lyophilisation or spray-drying to powder form. Residual solvents (acetonitrile, trifluoroacetic acid, dichloromethane), residual metals from catalysts, and free amino acid content are standard quality parameters that should be quantified. The white powder appearance is consistent with amorphous or microcrystalline peptide material, with typical bulk density ranging 0.2-0.6 g/cm3 for such products.

End users span cosmetic formulators, contract manufacturers, and R&D laboratories developing high-end face and body care. The material suits incorporation at active levels typical for signal peptides, though specific recommended use concentrations should be confirmed with the supplier. Zhenyibio Technology Inc. is located in Xi'an's high-tech district, a region with established pharmaceutical and biotechnology manufacturing infrastructure. The supplier's response metrics show zero platform-tracked activity, so buyers should initiate contact through multiple channels to assess responsiveness and technical competence before committing to volume orders.

Zhenyibio Technology Inc. is headquartered at No.29 Kejiliulu in Xi'an's Gaoxin District, Shaanxi Province, China, a location within one of the country's major biotechnology and pharmaceutical manufacturing clusters. The supplier holds a harbor trust tier, representing basic platform verification without enhanced due diligence or premium supplier status. The Kejiliulu address suggests a commercial or light industrial facility rather than a dedicated GMP manufacturing plant, though this should be confirmed through direct enquiry and, where possible, virtual or physical audit. No information is provided about founding year, employee count, annual production capacity, revenue figures, or named clients, and none should be invented.

The supplier's response rate and average response hours are both recorded as zero, indicating no platform-mediated communication history at the time of listing. This does not necessarily reflect operational incapacity but does mean buyers cannot rely on platform-tracked responsiveness metrics when planning procurement timelines. Zhenyibio Technology Inc. positions its Acetyl Tetrapeptide-11 for high-end cosmetic applications, emphasising skin feel and anti-aging efficacy in its product description. Buyers should independently verify whether the company performs peptide synthesis in-house or acts as a distributor, as this distinction affects technical support capability, batch-to-batch consistency guarantees, and regulatory documentation depth.
