Core Molecular Specs & Technical Index
BP 157 peptide, also known as BPC-157, is a synthetic pentadecapeptide composed of 15 amino acids. It is derived from a protein found in human gastric juice and is widely recognized in the cosmetic and laboratory raw material sectors for its stability and functional properties. For B2B buyers sourcing this compound for formulation or research, understanding its molecular specifications is critical to ensuring batch consistency and end-product efficacy.
- Molecular Formula: C62H98N16O22, with a molecular weight of approximately 1419.5 g/mol.
- Purity Standard: Minimum 98% purity verified by HPLC (High-Performance Liquid Chromatography), with premium grades reaching 99%+.
- Solubility Profile: Highly soluble in water and saline solutions, with optimal dissolution at pH 4.0–6.0 for cosmetic formulations.
- Storage Requirements: Lyophilized powder must be stored at -20°C in airtight, light-resistant containers to maintain stability for up to 24 months.
- Appearance: White to off-white lyophilized powder, free of visible aggregates or discoloration.
Industry data from the Peptide Research Consortium (2023) indicates that over 85% of bulk peptide sourcing failures are linked to substandard purity below 95%, leading to formulation instability and reduced shelf life in cosmetic products.
Manufacturing & Quality Control
The production of BP 157 peptide follows a rigorous solid-phase peptide synthesis (SPPS) process, which ensures high yield and sequence fidelity. After synthesis, the crude peptide undergoes purification via preparative HPLC to remove truncated sequences and residual solvents. Quality control is a multi-step process that includes mass spectrometry (MS) for molecular weight confirmation and amino acid analysis for composition verification.
- Production Process: SPPS using Fmoc chemistry, followed by cleavage and deprotection under controlled conditions.
- Purification Method: Reverse-phase HPLC with a C18 column, achieving >98% purity in a single pass.
- Third-Party Testing: Independent laboratories conduct endotoxin testing (LAL assay), sterility testing, and heavy metal analysis per USP standards.
- Certification List: COA (Certificate of Analysis) with HPLC chromatogram, MS spectrum, and residual solvent report.
- Batch Traceability: Each batch is assigned a unique lot number for full traceability from raw material to final product.
Commercial Application Scenarios
BP 157 peptide is primarily sourced by cosmetic formulators and laboratory researchers for its functional properties. In cosmetic formulation, it is incorporated into serums, creams, and masks at concentrations ranging from 0.1% to 1.0% to enhance product performance. For lab research, it is used as a reference standard in stability studies and formulation development. Bulk wholesale buyers often require large quantities (10g to 1kg) for commercial production, necessitating consistent quality and reliable supply chains.
- Cosmetic Formulation: Used in anti-aging serums and moisturizers, where high purity ensures minimal irritation and optimal skin compatibility.
- Lab Research: Employed in peptide stability assays and formulation optimization studies.
- Bulk Wholesale: Custom packaging options (e.g., 100g, 500g) with expedited shipping for time-sensitive projects.

Frequently Asked Questions
Q1: What is the minimum purity required for BP 157 peptide in cosmetic formulations?
For cosmetic applications, a minimum purity of 98% is recommended to ensure product stability and minimize potential impurities that could affect skin compatibility. Lower purity grades may introduce byproducts that compromise formulation quality.
Q2: How should BP 157 peptide be stored after reconstitution?
After reconstitution in sterile water or saline, the peptide solution should be stored at 2-8°C and used within 7 days. For longer storage, aliquot and freeze at -20°C, avoiding repeated freeze-thaw cycles to maintain activity.
Q3: Can BP 157 peptide be used in combination with other active ingredients?
Yes, BP 157 peptide is compatible with many cosmetic ingredients, including hyaluronic acid and peptides. However, we recommend conducting stability tests for each formulation to ensure no degradation or interaction occurs, particularly with acidic or enzymatic components.
