Acetyl Tetrapeptide-15: Bulk Supply & Technical Specs
Technical Specifications and Purity Grades of Acetyl Tetrapeptide-15
Acetyl Tetrapeptide-15, chemically known as N-Acetyl-L-tyrosyl-L-prolyl-L-phenylalanyl-L-phenylalaninamide, is a synthetic cosmetic peptide widely utilized as a skin soothing agent. In industrial procurement, the primary specification is purity, typically expressed as a percentage by HPLC. Standard commercial grades range from 95% to 99% purity, with higher grades reserved for premium skincare actives. The peptide content, often determined by quantitative amino acid analysis, is another critical parameter. For formulators seeking a drop-in replacement, it is essential to verify that the peptide content and purity align with the original material to ensure equivalent performance. At NINGBO INNO PHARMCHEM, we supply Acetyl Tetrapeptide-15 with a typical purity of ≥98%, suitable for demanding cosmetic applications. Please refer to the batch-specific COA for exact values.
Beyond standard purity, one non-standard parameter that experienced formulators monitor is the peptide's behavior under thermal stress. In our field observations, Acetyl Tetrapeptide-15 solutions may exhibit a slight viscosity increase when stored at temperatures below 5°C, which can affect pumping and mixing in automated production lines. This is not a degradation sign but a reversible physical change; gentle warming to room temperature restores normal flow. Additionally, trace impurities from synthesis, such as residual solvents or deletion sequences, can influence the final product's color. Our manufacturing process minimizes these impurities, ensuring a consistent white to off-white powder that does not impart unwanted hue to formulations.
For those evaluating cost-efficiency, our product serves as a seamless equivalent to branded versions. We have benchmarked our Acetyl Tetrapeptide-15 against leading commercial samples, confirming identical chromatographic profiles and in vitro soothing activity. This makes it a reliable choice for brands aiming to reduce raw material costs without reformulation.

Certificate of Analysis (COA) Parameters and Batch Consistency
Every shipment of Acetyl Tetrapeptide-15 from NINGBO INNO PHARMCHEM is accompanied by a comprehensive Certificate of Analysis. The COA documents key parameters that ensure batch-to-batch consistency, a critical factor for industrial formulators. Typical entries include appearance (white to off-white powder), identification by HPLC retention time and mass spectrometry, purity (≥98%), peptide content (≥85%), water content (Karl Fischer, ≤5%), and residual solvents (GC, meeting ICH limits). We also report specific optical rotation and pH of a 1% aqueous solution, though these are informational and not specification limits.
Batch consistency is maintained through rigorous in-process controls. We have observed that minor variations in lyophilization conditions can affect the bulk density of the powder, which may impact volumetric filling in automated packaging. Our production team adjusts cycles to keep bulk density within a narrow range, typically 0.3–0.5 g/mL. This attention to detail ensures that your formulation process remains uninterrupted. For a practical guide on incorporating this peptide into sensitive skin products, see our Acetyl Tetrapeptide-15 formulation guide for skin soothing agent applications.
| Parameter | Specification | Typical Value |
|---|---|---|
| Appearance | White to off-white powder | White powder |
| Purity (HPLC) | ≥98.0% | 98.5% |
| Peptide Content | ≥85.0% | 88.2% |
| Water Content (KF) | ≤5.0% | 3.2% |
| Residual Solvents | Meet ICH Q3C | Conforms |
Industrial Handling, Stability, and Bulk Packaging Solutions
Acetyl Tetrapeptide-15 is supplied as a lyophilized powder that is hygroscopic. Proper handling requires a dry environment; we recommend opening containers under controlled humidity (<40% RH) to prevent clumping. For long-term storage, the peptide should be kept at -20°C in sealed, light-protected containers. Under these conditions, stability studies indicate a shelf life of at least 24 months. In solution, the peptide is stable at neutral pH but may hydrolyze under strongly acidic or alkaline conditions. Formulators should avoid prolonged exposure to high temperatures during processing.
Our bulk packaging options are designed for global logistics efficiency. Standard offerings include 1 kg and 5 kg net weight in pharmaceutical-grade HDPE bottles, overpacked in aluminum foil bags with desiccant. For larger quantities, we provide 25 kg fiber drums with double PE liners. All packaging is compliant with international shipping regulations for non-hazardous chemicals. We do not offer IBC or 210L drums for this product due to its high value and low density. Shipments are consolidated at our Ningbo facility and dispatched via air freight or sea freight, depending on urgency and volume. Each package is labeled with product name, batch number, net weight, and storage conditions.
Comparative Performance: Acetyl Tetrapeptide-15 as a Drop-in Replacement
When sourcing Acetyl Tetrapeptide-15, procurement managers often seek a drop-in replacement that matches the performance of established suppliers. Our product has been validated in side-by-side assays measuring the soothing effect on sensory neurons. In a typical in vitro model using capsaicin-stimulated keratinocytes, our peptide reduced PGE2 release by 45% at 0.01%, comparable to the reference standard. This performance benchmark confirms that formulators can substitute our material without adjusting concentrations or expecting changes in efficacy.
Cost-efficiency is a primary driver for switching. By optimizing solid-phase peptide synthesis and purification, we achieve high yields that translate to competitive bulk pricing. Supply chain reliability is another advantage; we maintain safety stock of key raw materials and can scale production to meet tonnage demands. Our quality system ensures that every batch meets the same specifications, eliminating the need for incoming QC revalidation. For brands that have qualified a specific grade, we can provide a technical dossier to support the equivalence claim.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for Acetyl Tetrapeptide-15?
Our standard MOQ is 100 grams for initial trials. For commercial production, we typically supply in 1 kg increments. We can accommodate smaller quantities for R&D purposes; please contact our sales team for a quote.
