Description

Peg-4 Laurate CAS NO 10108-24-4 is a non-ionic surfactant and emulsifier derived from lauric acid and polyethylene glycol. This versatile chemical is valued for its excellent solubilizing, wetting, and stabilizing properties in a wide range of formulations. It is a critical ingredient for manufacturers in the personal care, cosmetics, pharmaceutical, and industrial cleaning sectors seeking effective and mild surface-active agents.

Application

• Personal Care & Cosmetics: Acts as a primary emulsifier and solubilizer in creams, lotions, and ointments, providing stable oil-in-water emulsions.
• Pharmaceutical Formulations: Used as an excipient in topical drug delivery systems to enhance the solubility and absorption of active pharmaceutical ingredients.
• Industrial & Institutional Cleaners: Serves as a wetting agent and detergent component in liquid soaps, degreasers, and hard surface cleaners.
• Textile Processing: Functions as a lubricant and softening agent in fiber treatments and fabric finishing operations.
• Agrochemical Adjuvants: Incorporated into pesticide and herbicide formulations to improve spreading and adherence on plant surfaces.
• Metalworking Fluids: Used as an emulsifier and corrosion inhibitor in soluble oils and coolants.
