Description
Propylene Glycol Diacetate (PGDA, CAS 623-84-7) is a diester formed by the acetylation of propylene glycol, commercially known under trade names including DOWANOL PGDA. It carries no assigned E-code and is identified under EC number 210-817-6 with the molecular formula C7H12O4.
In food and beverage formulations, PGDA functions as a flavorant by delivering a mild, fruity acetate note and acts as a carrier solvent to dissolve and stabilize lipophilic flavor compounds for uniform dispersion. In personal care products, it serves as a solvent for fragrance concentrates, improving their spreadability and controlled release on skin.
PGDA is available in technical and food-grade specifications, with compliance referenced against FCC (Food Chemicals Codex) standards and subject to REACH registration within the EU. It is supplied in standard drum and IBC formats. Procurement teams should confirm grade suitability against applicable food contact and cosmetic regulatory frameworks before use.
