Dipropylene Glycol (DPG) is a versatile organic compound widely used in multiple industrial fields, with its main applications as follows:

I. Cosmetics and Daily Chemicals

1. Fragrance and Flavor Solvent
   • As an ideal solvent for perfumes and fragrances (usage proportion exceeds 50%), it has excellent co-solvency for water, oil, and hydrocarbons, with a mild odor and low skin irritation.
   • Used in products such as hair curling solutions, skin lotions, shower gels, and lipsticks, acting as a humectant and coupling agent (typically added at ≤10%).

II. Polymer Material Processing

1. Resin Production
   • Used in the synthesis of unsaturated/saturated polyester resins, imparting superior flexibility, crack resistance, and long-term yellowing resistance.
2. Plasticizer and Solvent
   • Acts as a plasticizer for plastics (such as PVC and PC), enhancing flexibility and impact resistance.
   • Dissolves cellulose acetate, cellulose nitrate, shellac varnish, and castor oil.

III. Industrial Additives

1. Surfactant and Emulsifier
   • Used as an emulsifier, thickener, and lubricant to improve the performance of cleaning agents and metal cutting fluids.
2. Antifreeze and Anti-icing Agent
   • Applied in refrigeration systems and antifreeze processes in pharmaceutical production.

IV. Other Fields

1. Textile and Rubber Processing
   • Used for textile softening, rubber toughening, and wood preservation treatment.
2. Fumigant and Synthetic Detergent
   • Participates in synthetic detergent formulations and serves as a component of fumigants.
