2,2'-Oxydipropanol

2,2'-Oxydipropanol (CAS 108-61-2), also known as dipropylene glycol, is a diol solvent and humectant used across industrial and consumer formulation segments. It functions as a carrier, plasticizer, and coupling agent in applications where controlled evaporation and low toxicity are commercially relevant selection criteria.

In personal care and cosmetics, it acts as a humectant and solvent for fragrances, active ingredients, and preservative systems in lotions, creams, and hair care products. Textile and leather processors use it as a softening and lubricating agent during fiber treatment and finishing operations to ensure high-quality material output.

Printing ink and packaging formulators incorporate it as a solvent carrier to control viscosity and adhesion in water-based and UV-curable systems for industrial use. Polymer and plastics manufacturers use it as a plasticizer intermediate and reactive diol in polyurethane and polyester resin production for various durable goods.

The material is supplied as a clear, low-viscosity liquid in drum, IBC, and bulk tanker quantities. It is available in technical grade and cosmetic/personal care grade. The latter meets purity standards relevant to regulated formulation markets. Pharmaceutical-grade supply exists for select applications requiring documented impurity profiles.
