Why is Disodium Laureth Sulfosuccinate used in sulfate-free cleansers?

It is a sulfosuccinate surfactant rather than a traditional sulfate such as SLS or SLES. Its low irritation profile and stable lather make it suitable for sulfate-free shampoos, body washes, facial cleansers, and baby products.

What active content and liquid specifications should be checked?

Commercial grades are usually aqueous solutions with about 30-40% active content. Check the actual active matter, appearance, density of roughly 1.05-1.10 g/cm3, and the supplier pH value, which is commonly in the range of about 5.5-7.5 depending on the test concentration and grade.

Where is Disodium Laureth Sulfosuccinate commonly used?

It is used in personal-care products such as shampoos, body washes, facial cleansers, bubble baths, and liquid hand soaps. It is also selected for specialty and home-care cleaners that need foam and mild cleansing performance.

How does Disodium Laureth Sulfosuccinate compare with other sulfosuccinates?

It is a lauryl alcohol ethoxylate sulfosuccinate, so it differs from Sodium Lauryl Sulfosuccinate CAS 71963-18-3 and from DOSS/AOT CAS 577-11-7. The EO-chain distribution, active content, and application target should be confirmed for each grade.
