Methyl propionate-PEG12 is widely used in the formulation of personal care and cosmetic products due to its emulsifying and solubilizing properties. It helps stabilize mixtures of oil and water, making it a key ingredient in creams, lotions, and serums. In the pharmaceutical industry, it serves as a solubilizing agent for poorly water-soluble drugs, enhancing their bioavailability. Additionally, it is employed in industrial applications as a surfactant and dispersant, improving the performance of coatings, adhesives, and cleaning products. Its ability to modify surface tension and enhance solubility makes it a versatile compound across various sectors.
