2-(2-Hydroxypropoxy)-1-propanol

2-(2-Hydroxypropoxy)-1-propanol (CAS 106-62-7), commonly known as dipropylene glycol, is a diol solvent and humectant.

Where is 2-(2-Hydroxypropoxy)-1-propanol used?

• Home care and industrial cleaning: coupling solvent that keeps surfactant-based formulations stable and improves soil removal in hard-surface cleaners
• Coatings and adhesives: coalescing aid and plasticizing solvent that improves film formation and flexibility in waterborne systems
• Personal care: humectant and solvent carrier in lotions, serums, and fragrance bases
• Polymer processing: reactive intermediate or plasticizer in polyurethane and polyester resin systems
• Its low volatility and miscibility with water and organic solvents make it a practical carrier and coupling agent.

Good to know: Fragrance grade meets purity requirements set by IFRA and major flavor and fragrance buyers; technical grade is for coatings and polymer applications where cosmetic-grade purity is not required.
