Description

Disodium 4-[2,2-Bis(Hydroxymethyl)-3-[(1-Oxooctadecyl)Oxy]Propyl] 2-Sulphonatosuccinate is a high-performance, anionic surfactant and emulsifying agent derived from a succinate ester structure. This compound matters for its unique combination of excellent wetting, dispersing, and emulsifying properties, making it a critical component in formulations requiring stability and mildness. Industries such as personal care, cosmetics, and specialty detergents rely on this ingredient to create high-quality, stable emulsions and cleansing products.

Application

• Primary emulsifier in cosmetic and personal care formulations, including lotions, creams, and sunscreens.
• Mild surfactant in facial cleansers, shower gels, and baby care products due to its gentle nature on the skin.
• Stabilizing agent for oil-in-water (O/W) emulsions, preventing phase separation and improving product shelf life.
• Dispersing aid for pigments and actives in color cosmetics and topical pharmaceutical preparations.
• Foam booster and viscosity modifier in liquid soap and syndet bar formulations.
• Industrial emulsifier for specialty agrochemicals and coating applications where mild, biodegradable surfactants are required.

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 hygroscopic (moisture-sensitive); keep the container tightly sealed when not in use to prevent absorption of atmospheric moisture which may lead to caking or degradation.
