Diglycerol

Diglycerol (CAS 59113-36-9) is a polyol formed by the condensation of two glycerol molecules, commercially available under trade names including Diglycerin, Diglycerin S, DIG-S, K-COL-II, and Resassol DN. It carries no assigned E-code and is classified within the alcohols and glycols chemical family.

In personal care formulations, diglycerol functions as a humectant by binding moisture within the skin matrix, outperforming glycerol in certain high-humidity conditions due to its lower hygroscopicity. In polymer processing, it acts as a plasticizer by disrupting intermolecular chain interactions, improving flexibility in biopolymer and film applications. It also serves as a solvent and emulsification aid in pharmaceutical and food systems.

Diglycerol is supplied in compliance with REACH registration requirements and is available in food-contact and cosmetic grades. Buyers should confirm grade-specific purity specifications and applicable FCC or Ph.Eur. standards with the supplier prior to procurement. Packaging formats vary by volume requirement and application sector.
