Description

2-Ethyl-2-(Hydroxymethyl)Propane-1,3-Diyl Dimyristate is a high-purity synthetic ester, specifically a diester of trimethylolpropane and myristic acid. This compound is valued for its excellent emollient properties, chemical stability, and compatibility with a wide range of cosmetic and pharmaceutical ingredients. It serves as a key functional ingredient for formulators seeking to create luxurious, non-greasy textures and enhance product performance. Primary industrial users include manufacturers of personal care products, topical pharmaceuticals, and high-performance lubricants.

Application

• Cosmetic & Personal Care Formulations: Acts as a premium emollient and skin-conditioning agent in creams, lotions, sunscreens, and makeup products.
• Topical Pharmaceutical Bases: Used as a vehicle or excipient in ointments, gels, and medicated creams for its smooth spreading and stability.
• Specialty Lubricants & Release Agents: Functions as a synthetic base oil or additive in food-grade and industrial lubricants requiring high oxidative stability.
• Plasticizer & Polymer Additive: Imparts flexibility and low-temperature properties to polymers and resins in specialized applications.
• Industrial Surfactant & Emulsifier Intermediate: Serves as a chemical building block for the synthesis of more complex surfactants and emulsifying agents.
