What is Sodium Lauryl Sulfosuccinate CAS 71963-18-3?

Sodium Lauryl Sulfosuccinate is an anionic sulfosuccinate surfactant derived from lauryl alcohol and sulfosuccinic acid. It is used in detergent, cleaning, wetting, emulsifying, textile auxiliary, and selected rinse-off personal care formulations where cleansing, foaming, and surface-tension reduction are required.

How is Sodium Lauryl Sulfosuccinate different from Disodium Lauryl Sulfosuccinate?

They are related but not interchangeable. Sodium Lauryl Sulfosuccinate is the monosodium salt with CAS 71963-18-3, while Disodium Lauryl Sulfosuccinate has a different CAS number and two sodium counterions. Buyers should confirm the exact name, CAS number, formula, and specification before formulation or ordering.

What are the main industrial applications of this anionic surfactant?

It is commonly evaluated for household and industrial cleaners, detergent systems, wetting and emulsifying agents, textile auxiliaries, and rinse-off cleansing products. The most suitable grade depends on the desired foam profile, mildness, active content, physical form, and compatibility with the other formulation ingredients.

Which specification values should buyers confirm for Sodium Lauryl Sulfosuccinate?

Important values include active matter, physical form, pH, water or solid content, color, viscosity, residual sulfite or salt content, and compatibility with the target formulation. These parameters can differ substantially between powder, paste, and liquid commercial grades.

Can Sodium Lauryl Sulfosuccinate be used in mild personal care cleansing products?

It can be evaluated in selected rinse-off cleansing systems where a mild anionic sulfosuccinate surfactant is required. Formulators should confirm the cosmetic raw material grade, pH range, irritation profile, foaming behavior, and stability with the complete formulation rather than selecting by CAS number alone.
