Core Molecular Specs & Technical Index

The the ordinary multi peptide lash and brow serum is a water-soluble peptide complex with a molecular weight range of 500–1500 Da, ensuring optimal dermal penetration for topical application. The product is supplied as a clear to slightly opalescent liquid, with a pH range of 5.0–6.5, compatible with most cosmetic formulations. Purity is guaranteed at ≥98% by HPLC analysis, with no detectable heavy metals or microbial contaminants.

• Purity: ≥98% by HPLC, with individual peptide purity verified via mass spectrometry.
• Solubility: Fully soluble in water and standard cosmetic solvents (e.g., propylene glycol, glycerin) at concentrations up to 10% w/v.
• Storage: Recommended at 2–8°C in airtight, light-protected containers; shelf life of 24 months under these conditions.
• Stability: Stable at pH 4.5–7.0 and temperatures up to 40°C for short-term processing; avoid prolonged exposure to UV light.
• Technical Index: Peptide concentration per batch is standardized at 0.5% active peptide blend, with a viscosity of 1.5–3.0 cP at 25°C.

Industry data from the 2023 Cosmetic Peptide Market Report indicates that peptide-based lash and brow serums account for 18% of the global peptide cosmetic market, with a CAGR of 9.2% projected through 2028. The demand for high-purity, multi-peptide complexes like the ordinary multi peptide lash and brow serum is driving this growth, particularly in the Asia-Pacific and North American regions.

Manufacturing & Quality Control

The manufacturing process for the ordinary multi peptide lash and brow serum follows a rigorous GMP-compliant protocol, starting with solid-phase peptide synthesis (SPPS) using Fmoc chemistry. Each peptide sequence is synthesized individually, then purified via preparative HPLC to achieve the ≥98% purity threshold. The final blend is formulated under sterile conditions in ISO 7 cleanrooms, with in-process controls for pH, viscosity, and microbial load.

Quality control includes third-party testing by accredited laboratories (e.g., SGS or Eurofins) for heavy metals (lead, arsenic, mercury, cadmium), microbial limits (total aerobic count <100 CFU/g), and peptide identity via LC-MS. Certifications include:

• GMP Certification: Compliant with ISO 22716 for cosmetic raw materials.
• MSDS: Material Safety Data Sheet available for all batches.
• COA: Certificate of Analysis provided with each shipment, detailing purity, concentration, and stability data.
• Allergen-Free: No common allergens (gluten, soy, dairy) in the peptide blend.
• Vegan & Cruelty-Free: No animal-derived components or animal testing.

Commercial Application Scenarios

The the ordinary multi peptide lash and brow serum is versatile across multiple B2B applications. In cosmetic formulation, it is used as a key active ingredient in serums, gels, and emulsions for lash and brow enhancement products. Typical use levels range from 2–5% of the total formulation, depending on desired efficacy and product viscosity. For lab research, it serves as a reference standard for peptide stability studies or as a positive control in dermal penetration assays.

In bulk wholesale scenarios, the product is supplied in 1 kg, 5 kg, and 25 kg HDPE containers, with custom blending options available for private-label brands. Distributors often incorporate it into their catalog for contract manufacturers targeting the premium cosmetic segment. The product's compatibility with other active ingredients (e.g., hyaluronic acid, panthenol) makes it ideal for multi-functional formulations.

Bulk Purchase Selection Guide

When sourcing the ordinary multi peptide lash and brow serum for bulk procurement, B2B buyers must avoid common pitfalls such as accepting low-purity alternatives or unverified supplier claims. Key selection standards include:

• Verify Purity: Request a Certificate of Analysis (COA) with HPLC chromatogram for each batch.
• Check Solubility: Test a small sample in your target solvent system before full-scale purchase.
• Assess Stability: Ask for accelerated stability data (40°C/75% RH for 3 months) to ensure shelf life.
• Supplier Audit: Prefer suppliers with GMP certification and transparent manufacturing facilities.
• Minimum Order Quantity (MOQ): Typical MOQ is 1 kg; negotiate for smaller trial batches if needed.

A buyer checklist should include: COA, MSDS, batch number, expiry date, storage conditions, and a sample for in-house testing. Avoid suppliers offering prices below $800/kg, as this often indicates low purity or adulteration.

Core Product Advantages

The the ordinary multi peptide lash and brow serum offers distinct advantages for B2B buyers. Its high purity (≥98%) ensures minimal impurities that could cause formulation instability or adverse reactions. The multi-peptide blend provides a synergistic effect, targeting multiple pathways for lash and brow appearance, which is not achievable with single-peptide alternatives. Stability under standard cosmetic processing conditions (pH 5.0–6.5, up to 40°C) reduces formulation risks and extends product shelf life.

Cost performance is optimized through the product's high concentration (0.5% active blend), allowing for lower use levels in formulations without compromising efficacy. Additionally, technical support from the supplier—including formulation guidance, stability testing, and regulatory documentation—adds significant value for contract manufacturers and private-label brands.

Frequently Asked Questions

Q1: What is the recommended use level of the ordinary multi peptide lash and brow serum in cosmetic formulations?
The recommended use level is 2–5% of the total formulation weight. For serums, a 3% concentration is typical, while for gels or emulsions, 2–4% is sufficient. Always conduct a compatibility test with your base formula before scaling up.

Q2: How should I store the product to maintain its stability?
Store the product at 2–8°C in airtight, light-protected containers. Avoid freeze-thaw cycles and prolonged exposure to temperatures above 40°C. Under these conditions, the shelf life is 24 months from the date of manufacture.

Q3: Can this product be used in combination with other active ingredients like retinol or hyaluronic acid?
Yes, the product is compatible with most cosmetic actives, including hyaluronic acid, panthenol, and niacinamide. However, avoid combining with high concentrations of acids (pH <4.0) or strong oxidizing agents, as this may degrade the peptides. A stability test is recommended for new formulations.
