What is Propylene glycol diacetate?
Propylene glycol diacetate (CAS 623-84-7), commonly abbreviated as PGDA, is a diester solvent used across food, flavoring, and cosmetic applications. FEMA 4464.
Where is Propylene glycol diacetate used?
- Flavor manufacturing: carrier for flavor concentrates, dissolving and diluting concentrated compounds for beverages
- Confectionery and savory products: miscibility with polar and non-polar flavor components
- Fragrance: carrier solvent in fine fragrances and functional products
- Personal care: incorporation of fragrance and active ingredients into lotions, creams, and leave-on formulations
- It acts as a low-odor, stable diluent that does not compete with the target scent profile.
Good to know: FEMA-approved status positions it for direct use as a flavoring agent in food products requiring mild acetate character.
