CAS 110-98-5 — Dipropylene glycol, mixture of isomers

Dipropylene glycol is a colorless, odorless, hygroscopic liquid composed of a mixture of isomers, primarily used as a solvent, humectant, and coupling agent in personal care products, pharmaceuticals, and industrial applications. It functions as a solvent for dyes, resins, and essential oils, and helps retain moisture in cosmetics and medications. Dipropylene glycol is a safe, non-toxic chemical with no signal word classification under GHS. It is miscible with water, alcohols, and many organic solvents, with a molecular weight of approximately 134.17 g/mol and a boiling point around 232°C. It is stable under normal conditions but may degrade at high temperatures or in the presence of strong oxidizing agents. Molekula supplies Dipropylene glycol from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
