Zinc PCA Powder for Skin and Scalp Care | CAS 15454-75-8
Zinc PCA for Personal Care Production
Also known as zinc pyrrolidone carboxylate or zinc L-pyroglutamate, Zinc PCA is used in personal care products where moisture care and an oil-control positioning are combined. Common formats include facial toners, serums, lotions, creams, cleansing gels, shampoos and scalp lotions.
The powder format allows manufacturers to incorporate Zinc PCA into their own aqueous formulations. It is relevant to both leave-on and rinse-off development, with the addition level and processing conditions selected for the finished formula.
Unilong accepts production enquiries with an existing raw-material specification. Send your zinc content, moisture, solution pH and microbiological requirements together with the order quantity.
Technical Specifications for Quotation
Request a quotation against the following specification targets. The offered specification and test methods are agreed with the quotation.
| Test item | Target for quotation |
|---|---|
| Appearance | White to pale yellow powder |
| Zinc PCA assay | ≥98.0% |
| Zinc content, dry basis | 19.4–21.3% |
| pH, 10% aqueous solution | 5.0–6.0 |
| Loss on drying | ≤5.0% |
Zinc PCA assay and elemental zinc content are separate purchasing parameters. Include both requirements when they appear in your raw-material specification.
For projects with additional microbiological or impurity limits, send the required tests with your enquiry. These may include total microbial count, specified microorganisms, lead or arsenic. The quotation will identify the specification offered for your order.
Product identity: EC 239-473-5; molecular formula C10H12N2O6Zn; molecular weight 321.6 g/mol.
Applications in Skin and Hair Care
Facial Toners and Water-Based Serums
Zinc PCA is used in toners and serums developed for oily and combination skin. Its water solubility makes it relevant to aqueous formats, while the PCA component contributes to the ingredient's moisture-care role.
These products combine a fresh sensory profile with an oil-control concept. In transparent formulas, pH, thickener selection and electrolyte content affect clarity, viscosity and storage appearance. Include any clarity or color requirements in the product enquiry.
Lightweight Lotions and Creams
In facial lotions and creams, Zinc PCA is incorporated through the water-containing portion of the formulation. It is relevant to products intended to combine hydration with a less oily appearance, including lightweight moisturizers for combination skin.
Emulsifier selection and the rheology system influence incorporation into a finished cream. A production sample can be assessed in the intended base for appearance, viscosity and storage stability before the purchasing specification is finalized.
Shampoos and Oily Scalp Care
Zinc PCA is used in shampoos, scalp lotions and other hair care products developed for an oily scalp or a fresh hair feel. It offers a formulation option for manufacturers extending a skin-care ingredient strategy into scalp care.
Rinse-off shampoos and leave-on scalp products have different exposure and sensory requirements. Shampoo development also involves the surfactant blend, foam profile and viscosity. For a sourcing enquiry, identifying whether the product is rinse-off or leave-on helps define the technical discussion and the quantity needed for formulation trials.
Facial Cleansers and Shower Gels
Cleansing gels and shower products provide another application route for Zinc PCA. It is used alongside the surfactant system in products positioned around freshness, skin conditioning and care for oily skin.
The finished cleanser still relies on its overall surfactant and moisturizing system for cleansing performance and skin feel. For transparent products, appearance and viscosity are useful screening points when introducing an additional soluble ingredient. Finished-formula stability and preservation testing remain part of product development.
Formulation and Processing
Zinc PCA is water-soluble and is generally introduced through an aqueous portion of the formula. Dissolving it separately in a suitable amount of formulation water can help distribute the ingredient evenly during mixing.
Addition level, mixing sequence and processing temperature depend on the formulation. For an existing product, provide the target use level, product format and production quantity with your enquiry. Sample requests can cover trials in your complete thickener, surfactant or emulsion system.
Packaging and Commercial Supply
Packaging options for enquiry include 1 kg bags and 25 kg drums. Request a 25 kg drum quotation for production purchasing, or specify a smaller pack requirement for formulation work. Final net weight, inner packaging and outer container are included in the supply offer.
For an order covering several drums, include the total quantity and any pallet or delivery constraints. A 100 kg enquiry, for example, can specify four 25 kg drums. Packing, labeling and transport requirements can then be addressed together with the product quotation.
Unilong's usual shipment window is 7–15 days after order confirmation, subject to product availability and order requirements. The Zinc PCA dispatch schedule is confirmed in the quotation; transport time depends on the shipping route.
Store the material tightly closed in a cool, dry place, protected from light and moisture. Keep opened packaging sealed between uses. Request the storage instructions and shelf-life information applicable to the offered material with your order documents.
Product Documents and Sample Requests
Include your specification, TDS, SDS and COA requirements when contacting Unilong. We will confirm the available documents for the offered material and applicable batch.
For a formulation sample, state the quantity needed and the intended product format. Sample availability, packing, charges and dispatch arrangements are provided with the response.
If your procurement team requires additional impurity testing, a particular document language or destination-specific paperwork, include those requirements at the enquiry stage. This allows the offer to address the requested material and documentation together.
Procurement FAQ
Can I request a 99.0% assay specification?
Please send the required assay limit and test method. We will respond with the offered specification and availability for that requirement.
Is 25 kg the minimum order quantity?
The 25 kg figure is a packaging option for enquiry. The minimum order quantity is provided with the quotation for the requested specification and pack size.
