Description

Disodium (Z)-4-[2-[(2-Hydroxyethyl)(1-Oxooctadec-9-Enyl)Amino]Ethyl] 2-Sulphonatosuccinate is a high-performance, anionic surfactant and emulsifying agent derived from oleic acid and aspartic acid. This compound matters for its exceptional mildness, biodegradability, and ability to form stable, low-irritation foams and emulsions in demanding formulations. It is primarily needed by manufacturers in the personal care, cosmetics, and industrial cleaning sectors seeking effective, skin-friendly ingredients.

Application

• Primary Surfactant in Mild Cleansers: Used in facial cleansers, shower gels, baby shampoos, and sensitive skin formulations due to its low irritation potential.
• Foam Booster & Stabilizer: Enhances and stabilizes foam in liquid soaps, hand washes, and shaving products.
• Emulsifying Agent: Effective for creating stable oil-in-water (O/W) emulsions in creams, lotions, and sun care products.
• Industrial & Institutional (I&I) Cleaning: Applied in low-pH and neutral floor cleaners, car wash shampoos, and other specialty detergents for its compatibility and cleaning power.
• Textile & Leather Processing: Functions as a wetting agent, dispersant, and emulsifier in dyeing and finishing processes.
• Agricultural Adjuvants: Used as a component in pesticide and herbicide formulations to improve spreading and wetting on plant surfaces.
