Propylene Glycol

The CAS registry number for Propylene Glycol is 57-55-6. Its chemical formula is C3H8O2, with a molecular weight of 76.09 g/mol. Quote this number when requesting a quotation or checking documentation, as it identifies the substance unambiguously regardless of the trade name used.

Propylene Glycol is also referred to as 1, 2-Propanediol, MPG and PG. These names describe the same substance, so a specification or enquiry written against any of them can be matched to this product.

Propylene Glycol is supplied as Food grade. State the grade your process requires when requesting a quotation — where an alternative grade can be sourced, it is confirmed at quotation stage rather than assumed.

Propylene Glycol is supplied at a concentration of 99.9%. Concentration and assay are separate figures: the concentration describes the strength of the material as supplied, and the certificate of analysis issued for your consignment carries the measured values for that batch.

The purity/assay figure recorded for Propylene Glycol is 99.9%. Figures are typical values for the grade supplied; the certificate of analysis for your specific batch is the authoritative record and can be provided on request.

Propylene Glycol is described as clear, colorless, odorless liquid. Appearance is a useful first check on receipt of goods, though it does not replace the certificate of analysis for confirming that the material meets specification.

Common applications include unsaturated polyester resins — Monomer intermediate, food and pharmaceuticals — Solvent, humectant, stabilizer, cosmetics and personal care — Emulsifier, texture control, antifreeze and de-icing — Efficient cooling and freeze protection, paints and coatings — Solvent, viscosity modifier and laundry detergents — Solvent and stabilizing agent. The suitability of the product for a particular process depends on the grade and specification required, which is worth confirming against your own process conditions.

Propylene Glycol is supplied to the Water Treatment, Food Processing & Beverage, Agriculture & Agrochemicals, Mining & Minerals, Construction & Admixtures, Pharmaceuticals & Healthcare, Cosmetics & Personal Care, Cleaning & Detergents, Paints, Coatings & Inks, Textile & Leather Tanning, Oil, Gas & Energy and Laboratories & Research sectors. These are the industries this product is listed against in our catalogue; if your application falls outside them, we can advise on suitability before you order.

Available from 3.78L bottles to 200L drums. Where a different pack size or bulk delivery is required, it is confirmed at quotation stage against availability rather than listed here as standard.
