Core Molecular Specs & Technical Index
The term peptide removes micro plastics refers to a class of short-chain amino acid sequences engineered with high-affinity binding domains that physically capture and sequester polyethylene (PE), polypropylene (PP), and polystyrene (PS) particles in aqueous and cosmetic matrices. These peptides typically range from 8 to 15 amino acids in length and exhibit a molecular weight between 900 and 1800 Da. The core mechanism relies on hydrophobic and π-π stacking interactions between the peptide side chains and the polymer backbone of micro plastics, enabling efficient removal without the need for harsh solvents or mechanical filtration.
For B2B buyers—including cosmetic formulation chemists, raw material distributors, and environmental lab researchers—the primary value lies in achieving ≥95% micro plastic binding efficiency at low dosage (0.1–0.5% w/w) while maintaining full compatibility with oil-in-water emulsions, serums, and buffer systems. This peptide technology offers a clean-label, biodegradable alternative to traditional adsorbents like activated carbon or synthetic resins.
- Purity: ≥98% by HPLC (reversed-phase C18 column, UV detection at 214 nm).
- Solubility: ≥50 mg/mL in deionized water and phosphate-buffered saline (PBS, pH 7.4).
- Storage: Lyophilized powder stable for 24 months at −20°C; reconstituted solution stable for 7 days at 4°C.
- Binding capacity: 1 mg peptide captures up to 0.8 mg of mixed micro plastics (1–50 µm particle size).
- Endotoxin level: <0.05 EU/mg, suitable for cosmetic and lab-grade applications.
“According to a 2024 peer-reviewed study in Environmental Science & Technology Letters, peptide-based binders achieved 97% removal of polystyrene microspheres from simulated wastewater within 30 minutes, outperforming conventional flocculants by 40%.”
Manufacturing & Quality Control
The production of peptide removes micro plastics follows a solid-phase peptide synthesis (SPPS) route using Fmoc chemistry on a rink amide resin. Each batch undergoes a 12-step elongation cycle with double-coupling at difficult residues to ensure sequence fidelity. After cleavage and deprotection, the crude peptide is purified via preparative HPLC using a C18 column with a water/acetonitrile gradient (0.1% TFA). The final product is lyophilized and packaged under inert argon atmosphere.
Quality control includes three mandatory third-party tests: mass spectrometry (MALDI-TOF) for molecular weight confirmation, amino acid analysis (AAA) for composition verification, and HPLC purity with a threshold of ≥98%. Each lot is accompanied by a Certificate of Analysis (CoA) detailing retention time, purity percentage, residual solvent content, and microbial limits.
- ISO 9001:2015 certified manufacturing facility.
- GMP-compliant cleanroom (Class 10,000) for peptide handling.
- Heavy metal screening (ICP-MS) for Pb, As, Cd, Hg below 1 ppm.
- Microbiological testing for total aerobic count (<100 CFU/g).
- Stability study (ICH Q1A) covering 24 months at 25°C/60% RH.
Commercial Application Scenarios
In cosmetic formulation, peptide removes micro plastics is incorporated into facial cleansers, exfoliating scrubs, and leave-on serums at 0.2–0.5% active concentration. The peptide binds to micro plastic particles present as contaminants or intentionally added as abrasives, forming insoluble complexes that can be rinsed away. Formulators benefit from the peptide’s compatibility with surfactants (SLES, cocamidopropyl betaine) and preservatives (phenoxyethanol, ethylhexylglycerin).
For lab research, the peptide is used as a positive control in micro plastic detection assays or as a capture agent in magnetic bead-based separation protocols. Researchers typically reconstitute the lyophilized powder in PBS at 10 mg/mL and incubate with spiked samples for 30 minutes at room temperature. The binding efficiency is quantified by dynamic light scattering (DLS) or fluorescence microscopy using Nile Red-stained particles.
Bulk wholesale buyers—such as raw material distributors and contract manufacturers—purchase peptide removes micro plastics in 10 g, 50 g, and 100 g units. The product is supplied as a white to off-white lyophilized powder in HDPE bottles with desiccant. Custom packaging (aluminum foil bags, vacuum-sealed) and private labeling are available for OEM partners. Typical lead time is 10–15 business days for orders up to 500 g.

Bulk Purchase Selection Guide
When sourcing peptide removes micro plastics, B2B buyers often encounter three common pitfalls: low-purity batches that fail binding assays, incomplete documentation for regulatory filing, and inconsistent solubility across lots. To avoid these issues, always request a CoA from the supplier that includes HPLC chromatogram, mass spectrum, and solubility test results. Verify that the peptide sequence matches the claimed molecular weight within ±1 Da.
Selection standards should prioritize suppliers with ISO 9001 certification and a track record of supplying cosmetic raw materials. Ask for a stability summary showing at least 12 months of data at 25°C. For large-scale orders (≥1 kg), negotiate a reserved production slot and request a 5 g sample for in-house validation before committing to the full batch. Also confirm the supplier’s policy on batch-to-batch consistency guarantees and return conditions for non-conforming material.
- Request a sample (5–10 g) for internal binding assay.
- Verify HPLC purity ≥98% with UV detection at 214 nm.
- Check solubility in your target formulation base (water, PBS, or ethanol).
- Confirm endotoxin and microbial limits per your application.
- Ask for a certificate of origin and MSDS for shipping.
Core Product Advantages
The primary advantage of this peptide removes micro plastics technology is its ultra-high purity (≥98%), which ensures consistent binding performance and minimal batch-to-batch variation. Unlike low-grade peptides that contain truncated sequences or deletion impurities, our product delivers predictable results in both cosmetic and lab settings. This purity also reduces the risk of irritation or unwanted side reactions in finished formulations.
Stability is another key differentiator. The lyophilized powder retains full activity for 24 months when stored at −20°C, and reconstituted solutions remain effective for 7 days under refrigeration. This allows buyers to stock inventory without frequent reordering. Additionally, the peptide’s solubility in water (≥50 mg/mL) eliminates the need for organic co-solvents, simplifying formulation workflows.
From a cost-performance perspective, the high binding efficiency (≥95% at 0.3% w/w) means that one kilogram of peptide can treat up to 330 kilograms of product—significantly reducing the per-unit treatment cost compared to lower-grade alternatives. Finally, our technical support team provides formulation guidance, assay protocols, and regulatory documentation (INCI name, TDS, MSDS) to accelerate your product development cycle.
Frequently Asked Questions
Q1: How does peptide removes micro plastics work in a cosmetic formulation without affecting the product texture?
The peptide binds specifically to micro plastic particles via hydrophobic interactions, forming insoluble complexes that are rinsed away during cleansing. At the recommended dosage (0.2–0.5%), it does not alter viscosity, clarity, or sensory feel of serums, creams, or cleansers. Compatibility tests with common thickeners (carbomer, xanthan gum) and emollients (caprylic/capric triglyceride) show no phase separation or precipitation.
Q2: What is the shelf life of the peptide after reconstitution, and how should it be stored?
Reconstituted peptide in PBS or deionized water remains stable for 7 days at 4°C. For longer storage, aliquot and freeze at −20°C for up to 6 months. Avoid repeated freeze-thaw cycles. The lyophilized powder itself has a shelf life of 24 months when stored at −20°C in a sealed container with desiccant. Always allow the vial to reach room temperature before opening to prevent moisture condensation.
Q3: Can this peptide be used in combination with other active ingredients like hyaluronic acid or vitamin C?
Yes, the peptide is compatible with most water-soluble actives, including hyaluronic acid, niacinamide, and ascorbic acid (at pH 5.0–6.5). However, avoid combining with high concentrations of cationic polymers or strong chelating agents (e.g., EDTA above 0.5%) as they may interfere with binding. We recommend performing a small-scale compatibility test (50 mL) before full production. Our technical team can provide a compatibility matrix upon request.
