Description
Dipropylene glycol dibenzoate (CAS 27138-31-4) is a synthetic diester plasticiser and solvent, commercially available under trade names including K-Flex DP, Benzoflex 9-98, and Finsolv PG 22. It carries no E-code designation and is classified under HS code 29163100. The molecular formula is C20H22O5.
In solvent-borne coatings and adhesives, it functions as a coalescing agent and plasticiser, lowering the minimum film formation temperature and improving substrate adhesion without migrating rapidly from the film. In PVC and polymer formulations, it reduces melt viscosity during processing and imparts long-term flexibility to the cured material.
Dipropylene glycol dibenzoate is supplied as a liquid and is subject to REACH registration requirements for EU import and use. It is not listed under food-contact or pharmaceutical compendial standards such as FCC or Ph.Eur. Procurement teams should confirm supplier REACH compliance documentation and available pack sizes prior to ordering.
