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.

Sodium Lauryl Sulfosuccinate CAS 71963-18-3

Sodium Lauryl Sulfosuccinate CAS 71963-18-3 is an anionic sulfosuccinate surfactant used in cleaning products, detergent systems, wetting agents, and specialty formulations. It is selected for applications requiring surface activity, wetting performance, and formulation compatibility, with grade and active content confirmed according to the buyer’s process requirements. For milder sulfate-free cleansing systems, Disodium Laureth Sulfosuccinate is a related sulfosuccinate surfactant to compare by active matter, solvent system and foam profile.

Main Applications

Sodium Lauryl Sulfosuccinate CAS 71963-18-3 is an anionic sulfosuccinate surfactant used in industrial and formulation systems where wetting, cleansing, foaming, emulsifying, or surface-tension reduction is required. It is suitable for buyers looking for a functional surfactant raw material for cleaning, detergent, and specialty formulation use.

In B2B sourcing, Sodium Lauryl Sulfosuccinate is commonly considered for household cleaning products, detergent systems, wetting agents, textile auxiliaries, emulsions, and selected personal care or cosmetic raw material applications. The final suitability depends on active content, physical form, pH range, compatibility, foam profile, and the buyer’s formulation requirements.

Application Area	Buyer-Relevant Use Direction
Cleaning and Detergent Formulations	Used as an anionic surfactant for cleansing, wetting, and surface activity in selected detergent systems.
Household Chemical Raw Materials	Suitable for formulation development in cleaners, washing products, and related daily chemical systems.
Wetting and Emulsifying Systems	Applied where wetting, dispersion support, or emulsification performance is required.
Textile and Industrial Auxiliaries	May be used in auxiliary formulations that require anionic wetting or processing performance.
Personal Care Formulation Raw Materials	Can be evaluated in selected rinse-off or cleansing systems where a sulfosuccinate surfactant is required.

Product Specifications

Sodium Lauryl Sulfosuccinate may be supplied in different physical forms and active contents depending on the commercial grade. Buyers should confirm the exact specification before purchase, especially when the product is used in detergent, cosmetic, or industrial formulation systems.

For industrial procurement, commonly reviewed specification items include appearance, active matter, pH, water content, solid content, color, viscosity, free matter, salt content, and compatibility with the target formulation. Exact values should be confirmed with the current TDS, COA, or agreed supply standard.

Packaging and Supply

Sodium Lauryl Sulfosuccinate CAS 71963-18-3 can be supplied in standard industrial packaging according to its physical form, active content, and shipment requirements. Liquid or paste grades may use drum or IBC packaging, while powder or solid grades may use bags, cartons, or other suitable export packaging.

For quotation and supply evaluation, buyers are encouraged to provide the required active content, physical form, application field, order quantity, packaging preference, destination country or port, and document requirements. This helps confirm whether the available grade is suitable for cleaning products, detergent systems, textile auxiliaries, or other surfactant formulations.

Storage and Handling

Store Sodium Lauryl Sulfosuccinate in a cool, dry, and well-ventilated area. Keep containers tightly closed when not in use. Protect the product from moisture, contamination, direct sunlight, and excessive heat.

For liquid or paste grades, avoid freezing or long-term exposure to high temperature unless otherwise stated in the product TDS. Use suitable protective equipment during handling and avoid direct contact with eyes and skin. Users should review the latest SDS and technical data before formulation testing, transportation, storage, or production-scale use.
