Diglycerin

Diglycerin (CAS 59113-36-9) is a polyol dimer of glycerol used across cosmetic, food, and pharmaceutical manufacturing as a humectant, emulsifier, and solvent carrier. Its moisture-retaining and surface-active properties make it a functional ingredient. This material is often preferred where standard glycerol or propylene glycol falls short in performance or regulatory fit. In personal care formulations, it acts as a humectant and co-emulsifier in skin creams, serums, and hair conditioners.

The compound improves moisture retention and texture stability in various cosmetic applications. Food manufacturers use it as an emulsifier and carrier in fat-based systems, including confectionery coatings and bakery shortenings. In these food applications, it supports the uniform dispersion of ingredients throughout the mixture. Pharmaceutical formulators incorporate it as a solvent and plasticizer in topical preparations and soft capsule shells.

Its low volatility and compatibility with active ingredients are operationally relevant for drug delivery. In polymer and resin processing, it functions as a plasticizer and softening agent for industrial use. It is particularly useful in applications requiring a bio-based polyol alternative. The product is supplied as a viscous liquid, typically at purities ranging from 90% to 99%+ depending on the specific grade.

Food-grade and cosmetic-grade specifications are the most commonly traded, with technical-grade material available. It can be manufactured to meet FCC or USP standards depending on the end-use requirements. Packaging ranges from drums to IBC containers depending on volume requirements for global shipping. This versatile polyol remains a staple for manufacturers seeking high-performance humectancy and stability.
