Description

Disodium 4-Laureth Sulfosuccinate is a high-purity, anionic surfactant derived from lauryl alcohol ethoxylate and sulfosuccinic acid. This compound is valued for its excellent foaming, wetting, and emulsifying properties, even in hard water and across a wide pH range. It is a critical ingredient for formulators in the personal care, home care, and industrial cleaning sectors seeking mild yet effective performance.

Application

• Personal Care Formulations: A primary surfactant in mild shampoos, body washes, facial cleansers, and baby care products due to its low irritation profile.
• Cosmetic Products: Used in makeup removers, liquid soaps, and shaving creams for its gentle cleansing and rich lather.
• Household & Institutional Cleaners: An effective component in hard surface cleaners, dishwashing liquids, and carpet shampoos for superior degreasing and foam stability.
• Industrial & Technical Emulsions: Serves as an emulsifier and wetting agent in textile processing, agrochemical formulations, and polymer emulsions.
• Foam Stabilization: Enhances and stabilizes foam in various foam-based products and fire-fighting foams.

Quality Control

Our Disodium 4-Laureth Sulfosuccinate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent purity, performance, and compliance with relevant specifications for personal care ingredients. A comprehensive Certificate of Analysis (COA) documenting identity, assay, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is easily oxidized; prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal long-term stability. Keep away from strong oxidizing agents.
