Dipropylene glycol (DPG)

Dipropylene glycol (DPG) is a colorless, low-toxicity, slightly odorous, and highly hygroscopic organic liquid. It is an important chemical intermediate, primarily used as an ideal solvent, humectant, and coupling agent in fragrances, perfumes, and cosmetics (such as perfumes, skincare products, and shower gels). It is also widely used in unsaturated resins, plasticizers, cleaning agents, and coatings, imparting softness, weather resistance, and good solubility and mixing properties to products..

Product Details
