Description

Sodium Laureth-4 Carboxylate is a high-performance, mild anionic surfactant derived from ethoxylated lauryl alcohol. This compound is valued for its excellent foaming, cleansing, and emulsifying properties, even in hard water and across a wide pH range. It is a key ingredient for formulators in the personal care, home care, and industrial cleaning sectors seeking effective, skin-friendly, and biodegradable surfactant solutions. The product is supplied under stringent quality control to ensure batch-to-batch consistency and performance reliability.

Application

This versatile surfactant finds extensive use across multiple industries due to its mildness and efficacy.

• Personal Care Formulations: Primary surfactant in mild facial cleansers, shower gels, shampoos, and liquid soaps.
• Home Care Products: Key foaming and cleaning agent in dishwashing liquids, all-purpose cleaners, and hand soaps.
• Cosmetic Preparations: Used in makeup removers, shaving creams, and bubble baths for its gentle cleansing action.
• Industrial & Institutional (I&I) Cleaning: Component in formulations for floor cleaners, vehicle wash systems, and food processing area sanitizers.
• Textile Processing: Acts as a wetting agent and emulsifier in scouring and finishing baths.
• Agricultural Adjuvants: Can be used as a component in pesticide and herbicide formulations to improve spreading and wetting.
