Core Molecular Specs & Technical Index
Vilon peptide, a synthetic dipeptide (L-Lysyl-L-Glutamic acid), is a high-purity raw material designed for advanced cosmetic formulation and laboratory research. This peptide is characterized by its specific molecular weight of 275.30 g/mol and a molecular formula of C11H21N3O5. For B2B buyers in the cosmetic and lab raw material sectors, understanding the technical index is critical for ensuring batch-to-batch consistency and formulation stability. The core value of vilon peptide lies in its ability to support cellular signaling pathways in topical applications, making it a sought-after ingredient for anti-aging and skin conditioning products.
- Purity Level: Minimum 98% as determined by HPLC (High-Performance Liquid Chromatography), with premium grades offering 99%+ for research applications.
- Solubility: Readily soluble in water at 10 mg/mL, and partially soluble in DMSO and ethanol, facilitating easy incorporation into aqueous cosmetic bases.
- Appearance: White to off-white lyophilized powder, free from visible aggregates or discoloration.
- Storage Conditions: Stable at -20°C for long-term storage (24 months) and at 2-8°C for short-term use (6 months), protected from light and moisture.
- pH Range: Optimal stability in formulations with a pH of 5.0-7.0, ensuring peptide integrity in finished products.
Industry data from the Peptide Research Institute (2023) indicates that 98%+ purity vilon peptide batches show a 40% reduction in batch-to-batch variability compared to lower-grade alternatives, directly impacting formulation consistency in commercial production.
Manufacturing & Quality Control
The manufacturing of vilon peptide follows a rigorous solid-phase peptide synthesis (SPPS) process, which ensures high yield and minimal impurities. This method allows for precise control over amino acid sequence and chain length, critical for maintaining the peptide's bioactivity. Post-synthesis, the crude product undergoes multiple purification stages to achieve the required purity specifications.
- Production Process: SPPS using Fmoc chemistry, followed by cleavage and deprotection under controlled conditions.
- Purification: Preparative HPLC with C18 columns, achieving >98% purity with a single peak profile.
- Third-Party Testing: Independent labs verify purity via HPLC, mass spectrometry (MS), and amino acid analysis (AAA).
- Certification: Each batch includes a Certificate of Analysis (CoA) detailing purity, molecular weight, solubility, and endotoxin levels (<1 EU/mg).
- Stability Testing: Accelerated stability studies at 40°C/75% RH for 6 months confirm no significant degradation.
Commercial Application Scenarios
Vilon peptide is primarily utilized in cosmetic formulation and laboratory research, where its high purity and stability are paramount. In commercial settings, it is sourced in bulk for incorporation into serums, creams, and lotions targeting skin health and rejuvenation. For lab research, it serves as a standard for studying peptide-receptor interactions and cellular signaling.
- Cosmetic Formulation: Used at concentrations of 0.1-1.0% in anti-aging serums, where it supports collagen synthesis and skin barrier function.
- Lab Research: Employed in cell culture studies at 10-100 µM to investigate its effects on fibroblast activity and extracellular matrix production.
- Bulk Wholesale: Supplied in 1g, 5g, and 10g vials for large-scale manufacturing, with custom packaging options for OEM partners.
