Sulfosuccinic acid

Sulfosuccinic acid (CAS 5138-18-1 ) is a bifunctional organic acid carrying both carboxylic and sulfonic acid groups, used industrially as a surface-active intermediate and wetting agent.

It serves primarily as a building block for ester-based surfactants, particularly dialkyl sulfosuccinates, that appear across personal care, textile, and industrial cleaning formulations.

In textile and leather processing, sulfosuccinic acid derivatives improve fiber wetting and dye penetration, enabling more uniform treatment across various substrates and materials.

Personal care formulators use it as a precursor to mild surfactant esters found in shampoos, cleansers, and foam-based products where low irritation is a high formulation priority.

In printing and packaging, sulfosuccinate-based surfactants derived from this acid act as dispersants and wetting agents in specialized ink and coating systems for industrial use.

Industrial cleaning formulations rely on its esterified derivatives for degreasing and emulsification of oils and soils on hard surfaces in commercial and manufacturing environments.

Sulfosuccinic acid is typically supplied as an aqueous solution, with concentration varying by supplier. Technical grade is the most common commercial specification for these applications.

Buyers sourcing for personal care or cosmetic end products should confirm grade suitability and purity specifications with the supplier prior to procurement to ensure compliance.
