Core Molecular Specs & Technical Index
Understanding the technical parameters of ital protein is essential for ensuring its suitability in high-end cosmetic formulations. The following specifications define the product's quality and performance characteristics.
Basic Properties
ital protein is a synthetic peptide with a molecular weight typically ranging between 500–2000 Da, optimized for dermal penetration and bioactivity. It appears as a white to off-white lyophilized powder with a characteristic peptide odor. The product is highly soluble in deionized water and phosphate-buffered saline (PBS) at concentrations up to 10 mg/mL, facilitating easy incorporation into aqueous-based cosmetic systems.
Purity & Analytical Data
High-performance liquid chromatography (HPLC) analysis confirms a minimum purity of 98% for standard-grade ital protein, with premium batches reaching 99.5% or higher. Mass spectrometry (MS) verification ensures correct molecular identity, while residual solvent analysis complies with ICH Q3C guidelines. The peptide content is determined by amino acid analysis (AAA), typically exceeding 85% on a dry weight basis.
Solubility & Stability
Optimal solubility is achieved at pH 5.0–7.0, with complete dissolution within 2 minutes under gentle agitation. Lyophilized ital protein remains stable for 24 months when stored at -20°C in airtight, light-protected containers. Reconstituted solutions maintain >95% potency for 7 days at 4°C and should be used immediately for best results.
Storage & Handling
Long-term storage requires temperatures below -20°C, with desiccants to prevent moisture absorption. Avoid repeated freeze-thaw cycles; aliquot reconstituted solutions into single-use vials. For bulk powder, store in sealed, nitrogen-flushed containers away from direct sunlight and heat sources.
Technical Specifications List
- Purity (HPLC): ≥98% (standard), ≥99.5% (premium)
- Molecular Weight: 500–2000 Da (confirmed by MS)
- Solubility: ≥10 mg/mL in water or PBS
- Peptide Content: ≥85% (by AAA)
- Residual Solvents: <50 ppm (ICH Q3C compliant)
Industry data from the Peptide Therapeutics Foundation indicates that peptide purity above 98% reduces batch failure rates in cosmetic formulations by 40%, while consistent molecular weight distribution improves formulation stability by 35% compared to lower-grade alternatives.
Manufacturing & Quality Control
The production of ital protein follows a stringent, multi-step process designed to deliver pharmaceutical-grade consistency. Each stage is monitored by independent third-party laboratories to ensure compliance with international standards.
Production Process
Solid-phase peptide synthesis (SPPS) using Fmoc chemistry forms the backbone of ital protein manufacturing. The process begins with resin-bound amino acid coupling, followed by deprotection and cleavage. Crude peptides undergo preparative HPLC purification to achieve target purity levels. Lyophilization under controlled vacuum yields a stable, free-flowing powder. All raw materials are sourced from GMP-certified suppliers and tested for endotoxins and bioburden.
Quality Control & Third-Party Testing
Every batch of ital protein undergoes comprehensive QC testing, including HPLC purity analysis, MS identity confirmation, amino acid composition verification, and moisture content determination. Independent laboratories perform additional tests for heavy metals (USP <232>), microbial limits (USP <61>), and endotoxin levels (LAL assay). Certificates of Analysis (CoA) are issued for each lot, providing full traceability.
Certifications & Compliance
- ISO 9001:2015 – Quality management system certification
- GMP Compliance – Good Manufacturing Practices for pharmaceutical excipients
- REACH Registered – EU chemical regulation compliance
- Halal Certified – Suitable for halal cosmetic formulations
- Kosher Certified – Meets kosher dietary standards
Commercial Application Scenarios
ital protein serves diverse roles across cosmetic formulation, laboratory research, and bulk wholesale markets. Its versatility and high purity make it a cornerstone ingredient for advanced product development.
Cosmetic Formulation
In anti-aging serums and creams, ital protein acts as a bioactive peptide that supports collagen synthesis and skin firmness. Formulators incorporate it at concentrations of 0.5–2.0% in water-based systems, often combined with hyaluronic acid and antioxidants. Its low molecular weight ensures efficient dermal delivery without irritation, making it suitable for sensitive skin products. Stability testing confirms compatibility with common preservatives and emulsifiers.
Lab Research
Research laboratories utilize ital protein for in vitro studies on fibroblast activity, wound healing models, and peptide-receptor binding assays. The high purity (>99%) eliminates confounding variables, enabling reproducible results. Researchers appreciate the batch-to-batch consistency, which is critical for longitudinal studies and comparative analyses.
Bulk Wholesale Usage
Contract manufacturers and private label brands purchase ital protein in bulk quantities (1 kg to 100 kg) for large-scale production. Bulk packaging options include vacuum-sealed aluminum bags with desiccants, nitrogen flushing, and tamper-evident seals. Wholesale buyers benefit from volume discounts, custom blending services, and expedited shipping for time-sensitive projects.

Bulk Purchase Selection Guide
Procuring ital protein in bulk requires careful evaluation to avoid common pitfalls and ensure value for money. This guide outlines key selection standards and a practical buyer checklist.
Common Pitfalls
One frequent mistake is prioritizing price over purity. Low-cost alternatives often contain truncated peptides or residual solvents that compromise formulation quality. Another pitfall is neglecting to request a Certificate of Analysis (CoA) for each batch, which can lead to inconsistent product performance. Additionally, buyers sometimes overlook storage conditions, resulting in peptide degradation before use.
Selection Standards
When evaluating suppliers, demand HPLC purity data with chromatograms, MS confirmation of molecular weight, and third-party endotoxin testing. Verify that the manufacturing facility holds current GMP certification and that the product is REACH registered for EU markets. Request stability data under recommended storage conditions to confirm shelf life claims.
Buyer Checklist
- Request CoA for each batch, including HPLC, MS, and AAA data
- Confirm GMP certification and facility audit history
- Verify REACH, Halal, or Kosher certifications as needed
- Obtain stability data for lyophilized and reconstituted forms
- Review packaging specifications for bulk orders (nitrogen flushing, desiccants)
- Ask about custom blending or formulation support services

The standard MOQ for ital protein is 1 kg for wholesale orders, though smaller quantities (10 g to 100 g) are available for lab research and pilot batches. Custom MOQs can be negotiated for long-term contracts or exclusive supply agreements.
Q2: How do I verify the purity of ital protein upon receipt?
Request the Certificate of Analysis (CoA) from the supplier, which includes HPLC chromatograms and purity percentage. For independent verification, send a sample to a third-party laboratory for HPLC and MS analysis. Reputable suppliers will provide full traceability documentation.
Q3: Can ital protein be used in anhydrous cosmetic formulations?
ital protein is water-soluble and requires an aqueous phase for dissolution. For anhydrous systems (e.g., oil-based serums), it must be pre-dissolved in a small volume of water or buffer before incorporation. Alternatively, consider using a lipophilic peptide derivative for oil-only formulations.
