Sodium PCA CAS 54571-67-4 for Personal Care | Unilong
Product Overview
Sodium PCA (CAS 54571-67-4), also known as sodium DL-pyroglutamate, is a water-soluble humectant for personal care formulations. It attracts and retains moisture and is used in skin care, hair care and water-containing makeup. Sodium pyrrolidone carboxylate is another common name for this ingredient.
Unilong accepts bulk purchase enquiries from personal care manufacturers and raw material distributors. The 50% aqueous format is relevant to water-based products and emulsions that need a liquid humectant. Product selection centres on concentration, appearance and compatibility with the intended production formula, together with the required packaging and documentation.
Technical Specifications
Request a quote against the following specification targets for a 50% aqueous solution. Final limits and test conditions are agreed before order confirmation.
| Item | Enquiry Target |
|---|---|
| Appearance | Clear, colorless liquid |
| Sodium PCA content | 48.0–52.0% by weight; nominal 50% |
| pH | 6.8–7.4 |
| Carrier | Water |
| Water solubility | Water-soluble |
The content range applies to Sodium PCA in the supplied solution by weight. Additional chloride, sulfate, ammonium, trace element or microbiological requirements can be included in the specification request. Test availability and acceptance limits are agreed for the material offered.
50% Aqueous Form for Manufacturing
A nominal 50% aqueous solution combines the humectant and its water carrier in a liquid raw material. It can be weighed into a water-phase premix or incorporated through a suitable liquid addition stage. This format removes a separate powder dissolution step and suits production processes organised around liquid raw material handling.
The solution contributes both Sodium PCA and water to the formula, so the addition is included in the total water balance. Finished-product dosage is established for the intended formula and expressed on either a solution or Sodium PCA basis. For production transfer, a consistent basis between the master formula, weighing instructions and raw material description helps preserve the intended concentration. Liquid delivery does not by itself establish a use level, finished-product pH or preservative system.
Personal Care Manufacturing Applications
Face Creams and Body Lotions
Sodium PCA provides a water-phase humectant for moisturizing creams, facial emulsions and body lotions. It contributes moisture binding within the aqueous phase alongside the formula’s oil-phase emollients. These ingredients serve complementary roles in a moisturizing emulsion. Humectant level, emollient selection and rheology can be balanced for a light lotion or a richer cream texture.
Serums, Toners and Facial Masks
Water-based serums, toners and facial mask liquids can incorporate Sodium PCA for humectancy. Its water solubility supports use in aqueous bases where the intended texture ranges from a fluid toner to a structured gel. Color and clarity are relevant raw material attributes for transparent products. In thickened systems, compatibility with the chosen polymer and electrolyte balance influences the viscosity and clarity achieved.
Facial Cleansers and Body Wash
Sodium PCA can serve as a humectant in facial cleansers and liquid body wash. In these systems, it forms part of the conditioning package alongside the surfactant blend. The useful addition level is linked to the finished product’s viscosity, foam profile and rinse feel. The aqueous format can be incorporated during preparation of the water-containing base in gel or liquid cleansing products.
Shampoos and Hair Conditioners
Hair care manufacturers use Sodium PCA in moisturizing shampoos, conditioners and related aqueous treatments. It provides a humectant component in formulas developed around hair feel and moisture management. Water-containing rinse-off and leave-on systems offer different contact times and sensory targets for the formulation. The surfactants, conditioning polymers and any emulsion structure remain important to its integration into the finished product.
Water-Containing Makeup
Liquid foundations and other water-containing makeup products can use Sodium PCA as part of their humectant system. Its role is relevant where the formula includes an aqueous phase and a desired moisturizing feel. The liquid contributes to that aqueous phase while the pigment and emulsion systems provide coverage and structure. For these formulations, the humectant level is balanced with texture, spreadability and the intended afterfeel.

Formulation and Processing
Sodium PCA 50% liquid is suited to addition through the aqueous portion of a formulation. Mixing distributes it through the water-containing base before the final texture is set. The addition stage follows the manufacturing process and the stability requirements of the other ingredients, without a universal temperature or shear setting for every product.
As a sodium salt, Sodium PCA contributes to the electrolyte content of the formula. This matters in clear gels and other systems whose viscosity changes with dissolved salts. The thickener and electrolyte balance therefore influence the final texture, even when the raw material itself dissolves readily in water.
The raw material pH target is a quality parameter for the liquid. The finished formulation has its own pH, preservation and stability requirements. Avoid combinations with nitrosating agents. The composition and preservative status of the offered raw material are included in the document request when they are relevant to the formulation brief.
During liquid transfer, clean dispensing equipment and prompt container closure help protect the material from contamination. Open-container handling can also change the water content through evaporation. For repeat production, the formulation record needs a clear concentration basis, while the supplied lot documents provide the applicable material information. These practical handling points are especially relevant to partial-container use across several production batches.
Quality Control and Product Documents
Identity, Sodium PCA content, appearance and pH are relevant quality attributes for this aqueous material. Content supports consistent formula addition, while appearance and color matter to clear or lightly colored products. Additional impurity and microbiological limits depend on the agreed purchasing specification and testing scope.
Request the applicable specification or TDS, SDS and lot-specific COA with the quotation. Document availability and test coverage are confirmed for the material offered. Include any composition statement, origin declaration or destination-specific document needed for your purchasing process; availability is addressed with the offered grade.
For repeat production orders, the approved specification and previous order reference keep the required material clear. For production material changeovers, the existing specification defines the requested concentration and any additional limits. Unilong will address the requested specification and documents as part of the supply discussion.
Packaging, Storage and Commercial Supply
For 50% liquid enquiries, request pricing for 25 kg liquid containers, including a plastic drum option. The quotation confirms the available container, net weight and packing arrangement. Larger order quantities can be discussed with the destination and handling requirements specified.
