Description

Laureth-4 is a non-ionic surfactant belonging to the polyoxyethylene lauryl ether family, valued for its excellent emulsifying, wetting, and solubilizing properties. This versatile chemical is essential for formulators seeking to create stable, high-performance products across a range of industries. It is particularly critical for manufacturers in the personal care, cosmetics, pharmaceutical, and industrial cleaning sectors who require a reliable, high-quality ingredient.

Application

• Personal Care & Cosmetics: A key emulsifier and solubilizer in creams, lotions, shampoos, and bath products, helping to blend oil and water phases for stable formulations.
• Pharmaceuticals: Used as a solubilizing agent and emulsifier in topical ointments, creams, and certain liquid drug delivery systems.
• Industrial & Institutional (I&I) Cleaning: Acts as a surfactant and wetting agent in heavy-duty degreasers, hard surface cleaners, and textile processing aids.
• Agrochemicals: Functions as an adjuvant in pesticide and herbicide formulations to enhance spreading and penetration on plant surfaces.
• Paints & Coatings: Serves as a dispersing and wetting agent to improve pigment dispersion and stability in water-based systems.
• Metalworking Fluids: Used as an emulsifier in soluble oils and synthetic coolants to provide lubrication and cooling during metal machining.
