Request SDS →Diglycerol (CAS 627-82-7) is a polyhydric ether-alcohol formed from two glycerol units. It is used as a humectant, solvent, and chemical intermediate, and is recognized in cosmetic nomenclature (diglycerin) as a solvent and humectant.
Frequently Asked Questions
What is diglycerol?
Diglycerol (CAS 627-82-7) is a polyhydric ether-alcohol formed from two glycerol units joined by an ether linkage (C6H14O5). It is used as a humectant, polyol solvent, and chemical intermediate, and is recognized in cosmetic nomenclature as diglycerin. RawSource supplies it in bulk to personal-care and specialty-chemical formulators.
What is diglycerol made from?
Diglycerol is produced by the controlled etherification (polymerization) of glycerol, joining two glycerol molecules through an ether bond with loss of water to give C6H14O5. It is the first oligomer in the polyglycerol series and a feedstock for polyglycerol esters.
Is diglycerin the same as glycerin?
No. Glycerin is a single three-carbon triol, while diglycerin (diglycerol) is two glycerol units linked by an ether bond, giving it a higher molecular weight (C6H14O5) and more hydroxyl groups. Diglycerol is more viscous and has higher humectancy and a higher boiling point than glycerin.
What is the CAS number for diglycerol?
Diglycerol's CAS number is 627-82-7, formula C6H14O5, classified under HS 2909.49 (ether-alcohols, other). RawSource provides a Certificate of Analysis and SDS with each bulk shipment to confirm grade.
What is the cost of bulk diglycerol?
Bulk diglycerol pricing depends on volume, purity grade, packaging, and freight. RawSource quotes against current supply; request a bulk quote with your target volume and ship-to for current pricing.
