Poly(propylene glycol) is widely used in various industries due to its versatile properties. In the production of polyurethane foams, it serves as a key component, providing flexibility and durability to the final product. It is also employed as a lubricant in machinery and equipment, reducing friction and wear. In the pharmaceutical and cosmetic industries, it acts as a solvent, emulsifier, or stabilizer in formulations such as creams, lotions, and ointments. Additionally, it is used in the food industry as an antifoaming agent and in the manufacturing of adhesives and sealants to enhance performance. Its water-soluble nature and low toxicity make it suitable for applications in personal care products and industrial processes.
