Product Overview

Disodium lauryl sulfosuccinate is a premium mild anionic surfactant that serves as a core functional surfactant in cosmetic and daily chemical formulations, featuring ultra-low skin and eye irritation, excellent water solubility, stable foaming performance, and outstanding detergency with moderate degreasing capacity. As a high-performance and environmentally friendly surfactant, disodium lauryl sulfosuccinate possesses low surface tension, good hard water resistance, and superior biodegradability, without leaving tight or greasy residues on skin and hair after use. This versatile surfactant exhibits excellent compatibility with various nonionic, anionic, and amphoteric surfactants, effectively optimizing the foaming stability and cleansing gentleness of compound formulas while reducing the irritation of other strong surfactants in the system. Widely applicable in mild personal care products, disodium lauryl sulfosuccinate is extensively incorporated as a key cleansing surfactant in facial cleansers, baby shampoos, color-protective hair care products, body washes, hand cleansers and sensitive-skin care formulations, and it can also act as an emulsifying and wetting surfactant in daily chemical and fine chemical industrial formulas to improve product texture and use experience.
