Peg - 400

Description :

PEG 400 Supplier and Exporter for the UK

Chemical Bull supports PEG 400 sourcing for UK buyers, serving industrial formulators, personal care manufacturers and qualified excipient buyers. Share your required grade, specification and order quantity to request a supply quotation. Our role is to coordinate the offered material and commercial details against your purchasing requirements.

What Is PEG 400?

PEG 400 is a lower-molecular-weight polyethylene glycol grade, normally supplied as a viscous liquid. The grade number indicates an approximate average molecular mass rather than a single molecular species.

CAS number: 25322-68-3. Confirm this identity against the documentation for the supplied material.

PEG 400 Uses and Industrial Applications

Industrial formulation

PEG 400 is evaluated as a carrier, lubricant or processing aid where its compatibility and physical properties match the formulation. Water and colour limits should reflect the end use.

Personal care manufacture

Qualified grades can function as solvents or humectant ingredients in selected formulations. Assess skin-product suitability and relevant impurity documentation for the supplied grade.

Pharmaceutical excipient sourcing

Compendial grades may be considered for validated excipient applications. Industrial PEG 400 should not be substituted without qualification and documentation review.

Choosing the Right PEG 400 Grade

For bulk PEG 400 procurement, specify average molecular mass range, hydroxyl value, water, acidity and relevant impurity limits. Where the manufacturer uses a trade grade or a particular test method, include that reference in your enquiry. The offered specification should match the material you intend to approve for production.

Specify the PEG grade and the quality standard required by the application. The average molecular mass range, hydroxyl value and impurity controls are more informative than the grade number alone. Industrial, cosmetic and compendial materials need different qualification. For pharmaceutical use, identify the required monograph and supporting documentation before commercial discussion. Physical form and melting or dissolution behaviour should also suit the equipment used to charge and mix the formulation.

Production Trials and Quality Checks

Assess the ingredient at the actual concentration and processing temperature. Compare clarity, viscosity and stability with the existing formulation. Where the product is used as an excipient, include the required quality qualification and relevant impurity testing rather than approving it solely on physical performance.

For repeat supply, agree the acceptance limits and document requirements before the first commercial order. Review the batch Certificate of Analysis against that specification, and keep a retained sample where your quality procedure requires it. If a test method differs between sources, resolve that difference before treating the results as equivalent.

Storage and Handling

Keep storage and transfer conditions consistent with the SDS and the technical data for the supplied form. Prevent contamination and account for any water uptake that could alter the specification. For solid grades, establish a controlled dissolution or melting procedure. For liquid grades, confirm transfer arrangements and container cleanliness.

PEG 400 MSDS, SDS and Technical Documentation

Request the current PEG 400 MSDS or Safety Data Sheet (SDS) for the exact offered grade. The document covers hazard identification, handling, storage, exposure controls and transport information. Ask separately for the product specification, Technical Data Sheet where available, and a batch Certificate of Analysis. An SDS supports safe-use assessment; it does not replace a quality specification or demonstrate finished-product approval.

PEG 400 Price and Bulk Supply for UK Buyers

The PEG 400 price for UK delivery depends on the grade, quantity, packaging, source and agreed delivery terms. Include your delivery postcode, required date and purchasing frequency when requesting a quotation. State whether the destination is in Great Britain or Northern Ireland so the relevant supply arrangements can be reviewed. Availability, freight and any import responsibilities should be confirmed in the quotation before an order is placed.

Frequently Asked Questions

1. What is PEG 400?

PEG 400 is a lower-molecular-weight polyethylene glycol grade, normally supplied as a viscous liquid. The CAS number is 25322-68-3.

2. What is PEG 400 used for?

Applications include industrial formulation, personal care manufacture, pharmaceutical excipient sourcing. The required grade and finished-product suitability depend on the actual formulation or process.

3. Is PEG 400 the same as PEG 4000?

No. They differ in average molecular mass and physical form. Those differences can change handling, solubility, viscosity and formulation performance.

4. How can I request a bulk PEG 400 price for the UK?

Send the product name, approved specification, required quantity, packaging preference and UK delivery postcode. Include your target date and documentation requirements for a relevant quotation.

5. Can I request a PEG 400 MSDS?

Yes. Ask for the current SDS/MSDS for the offered grade, together with the product specification and available COA or TDS. Review the documents before approving the material.
