Are all DOSS or AOT products with CAS 577-11-7 directly dosage-equivalent?

No. The same sodium bis(2-ethylhexyl) sulfosuccinate identity may be supplied as dry material or as solutions or pastes with different active content and carrier. Compare active matter, water or solvent, pH, appearance, and method-specific wetting or emulsification behavior, then calculate dosage on an active basis.

Sodium Bis(2-ethylhexyl) Sulfosuccinate (DOSS/AOT) CAS 577-11-7

Sodium Bis(2-ethylhexyl) Sulfosuccinate (CAS 577-11-7), also called DOSS or AOT, is an anionic sulfosuccinate surfactant used where rapid wetting, dispersion or emulsification is required. Commercial grades may differ in active-matter level and carrier. Confirm active matter, carrier, water, acidity or pH, color, physical form and wetting performance against the current COA, TDS and SDS.

Application and grade selection

DOSS/AOT is an anionic sulfosuccinate surfactant used where rapid wetting, dispersion or emulsification is required. Commercial products with the same abbreviation can differ in active matter, carrier, flash point, viscosity and dosage.

Textile and cleaning evaluations should use a defined wetting-time or dynamic-surface-tension method at the intended concentration, pH, hardness and temperature.
Coating, dispersion and agrochemical trials should check foam, clarity, phase stability and performance with the actual solvent, electrolyte and active ingredients.
Compatibility with strongly cationic materials must not be assumed; test the concentrate and use dilution for turbidity, precipitation and loss of performance.

Storage and handling

Store in the original closed package under the conditions stated in the SDS. Temperature limits, fire precautions and transport requirements depend strongly on whether the grade is a solid or a solution and on the identity and concentration of its carrier.

Safety and supply documentation

Follow the exact-grade SDS for personal protection, spill response, incompatibilities, transport and disposal.

Before quotation, state the required active matter, carrier, wetting-test method, application, quantity, destination and package, and request the current specification, COA, TDS and SDS.
