Grades and Purity of DPG
Manufacturers typically offer DPG in different grades to suit various applications and specific usage requirements.
Each grade meets the unique needs of different industries and delivers optimal performance and reliability.
Fragrance Grade (or Lo+):
This is a high-purity, distilled product with an exceptionally low odor.
It is specifically designed for use in sensitive applications like perfumes, cosmetics, and personal care products where the odor of the solvent must not interfere with the final product’s fragrance.
Industrial Grade:
This grade is suitable for a wide range of industrial applications where odor is not a critical factor.
Uses of DPG
Cosmetics and Personal Care:
Used as a solvent, humectant, and carrier in products like perfumes, moisturizers, deodorants, and hair care products.
Chemical Intermediate:
A vital component in the production of unsaturated polyester resins (UPR), polyurethane polyols, and other resins.
Paints, Coatings, and Inks:
Serves as a solvent and coupling agent to improve the performance and finish of a wide range of formulations.
Functional Fluids:
Used in industrial and automotive applications as a base fluid for heat transfer, antifreeze, and hydraulic brake fluid formulations.
Other Industrial Applications
De-icing fluids
Cutting oils
Agricultural chemical formulations
Industrial cleaning products
Specialty solvent systems
