Who is this ingredient supply intended for?
This supply enquiry is intended for cosmetic manufacturers, OEM/ODM producers and ingredient distributors purchasing raw materials for commercial production or distribution.
Arginine/Lysine Polypeptide CAS 31014-78-5
Product Overview
Arginine/Lysine Polypeptide is the INCI name for L-arginine polymerised with L-lysine. Its cosmetic function is skin conditioning, and it is considered for peptide-based facial care formulations. Commercial preparations differ in peptide profile, concentration and carrier composition. The grade description therefore includes the complete supplied preparation as well as the peptide ingredient name.
Unilong accepts commercial raw-material enquiries from cosmetic manufacturers, OEM/ODM producers and ingredient distributors. Purchasing requirements are discussed in terms of production-order quantities and planned purchasing schedules. Each enquiry is handled against the required composition and concentration, with supply availability and commercial terms set out in the quotation.
Replacement sourcing can reference an existing raw-material specification used in production. For a new production supply requirement, the intended product format and required concentration provide the basis for identifying a documented supply option.
Technical Information for Quotation
Quotations identify the peptide concentration, carrier composition and grade-specific physical properties. Numerical limits and analytical methods are agreed for the preparation being quoted.
| Technical item | Quotation details |
|---|---|
| Supplied form | Requested preparation and carrier system |
| Appearance | Grade-specific colour and clarity |
| Composition | Peptide ingredient, carrier and any other declared components |
| Peptide content | Mass fraction, measurement basis and applicable method |
| Dry extract | Separate dry-matter value where relevant |
| pH | Value or range with the applicable measurement conditions |
| Peptide profile | Peptide composition and molecular-size information for the selected grade |
| Microbiological requirements | Agreed test items and acceptance limits |
For solution grades, peptide content and dry extract are reported on their respective measurement bases. A defined peptide profile, where required, forms part of the material specification together with concentration and carrier composition.
Cosmetic Manufacturing Applications
Facial Serums and Essences
Arginine/Lysine Polypeptide can be considered as a skin-conditioning ingredient in facial serums and essences. An aqueous grade provides a route into a water-rich base when the carrier matches the formula. Transparent products place particular emphasis on the colour and clarity of the raw material. Serum enquiries can include the final pH, alcohol content and target addition rate alongside the required peptide concentration.
Creams and Lotions
Creams and lotions are water-containing cosmetic formats in which a suitable peptide preparation can be incorporated. A liquid grade contributes both the peptide ingredient and its carrier to the emulsion composition. The selected preparation determines the applicable addition temperature and manufacturing stage. Emulsion enquiries can specify the final pH, process temperature and quantity of supplied ingredient required for each production batch.
Facial Gels and Gel Creams
Facial gels and gel creams are manufacturing formats for skin-conditioning products containing this ingredient. The peptide preparation forms part of a system containing a selected gelling agent and liquid carrier. Colour, clarity and viscosity depend on the complete formula, including the components introduced with the preparation. A grade-matching enquiry can identify the thickener system and the finished-product requirements relevant to the raw material.
Eye-Area Cosmetic Products
This ingredient can be considered for cosmetic eye creams and serums as a skin-conditioning component. The material requirement can identify the carrier, preservative components and microbiological limits for the intended eye-care formula. Eye-care specifications can state these requirements together with the peptide concentration. Unilong accepts eye-care ingredient enquiries against an existing material specification or a clearly described formulation requirement.
Multi-Peptide Facial Care
Multi-peptide facial care ranges may include this ingredient alongside other separately specified cosmetic peptides. Each preparation contributes its own concentration, carrier and additional components to the overall formula. The full blend composition determines the ingredient declaration and material quantities required for production. Unilong accepts enquiries for the individual raw material with the intended blend application identified in the request.
Formulation and Concentration Information
For liquid-grade enquiries, the full carrier composition is part of the material description. Water, glycols and any preservatives introduced with a preparation contribute to the finished formula as well as to its ingredient declaration. A change in commercial preparation can therefore change the carrier contribution even when the same INCI peptide name appears on the specification.
Addition temperature, working pH and use level are established for the selected preparation and the intended formula. The quotation can address a specified processing requirement together with the material composition. For an established formula, the existing addition rate and raw-material concentration provide the basis for a replacement enquiry.
For production planning, quotations can distinguish the quantity of supplied ingredient from the quantity of peptide it contains. This is particularly relevant when a purchasing requirement is expressed as active peptide mass while the manufacturing formula uses a liquid preparation. The concentration basis remains part of the agreed material description.
Quality and Product Documents
Ask Unilong for the technical and safety documents available for the selected commercial preparation. TDS and SDS availability is addressed for that preparation, including its concentration and carrier composition. Requests for a COA relate to the applicable commercial supply lot and the test coverage available for it.
The technical requirement can include identity, appearance, peptide content, dry extract where relevant, pH and microbiological limits. Requested limits and analytical methods form part of the supply enquiry. These details establish the material description used for the quotation and any subsequent order agreement.
Destination-specific document requirements can accompany the initial enquiry, with availability and scope addressed before purchase. Unilong's service contact provides a route for discussing the material, commercial terms and shipment requirements together. Document requests identify the required preparation and destination so the applicable information can be considered for that order.
Packaging, Storage and Commercial Supply
For liquid-grade production orders, a 25 kg container requirement can be included in the commercial supply enquiry. The actual net weight, container material and outer packing are established with the quoted grade and total order quantity. Packing details can reflect the receiving factory's handling arrangements and the required transport conditions.
Storage temperature, shelf life and transport conditions are specified for the selected preparation. Any refrigeration or temperature-controlled transport requirement is addressed in the supply quotation. The packing enquiry can also identify receiving-site restrictions on container size or handling, with the applicable arrangement agreed before dispatch.
Unilong's general policy is usually shipment within 7–15 days after order confirmation. The schedule for this ingredient depends on grade availability, production-order quantity, document requirements and any temperature-control arrangements. The applicable dispatch dates and shipping terms are included in the commercial quotation, with transit time addressed for the destination.
