Description

Myreth-3 Myristate is a high-purity, non-ionic surfactant and emollient ester derived from myristic acid and a short-chain polyethylene glycol ether. This compound is valued for its excellent skin feel, solubilizing properties, and ability to enhance the spreadability and texture of formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, and pharmaceutical industries seeking to create stable, luxurious, and effective end products.

Application

• Personal Care & Cosmetics: Acts as a premium emollient and skin-conditioning agent in creams, lotions, and sunscreens, providing a non-greasy, silky after-feel.
• Hair Care Formulations: Used in conditioners, hair masks, and styling products to impart shine, reduce static, and improve combability.
• Pharmaceutical Topicals: Serves as a solubilizer and penetration enhancer in ointments, gels, and transdermal drug delivery systems.
• Fragrance & Essential Oil Solubilization: Effectively solubilizes lipophilic fragrances and oils in aqueous-based products, enhancing clarity and stability.
• Color Cosmetics: Improves pigment dispersion and application smoothness in foundations, lipsticks, and makeup products.
• Industrial Applications: Functions as a lubricant, plasticizer, or processing aid in specialized chemical synthesis and polymer applications.
