What is Disodium Laureth Sulfosuccinate CAS 39354-45-5?

Disodium Laureth Sulfosuccinate is a mild anionic surfactant, chemically described as an ethoxylated lauryl alcohol sulfosuccinate disodium salt. It is normally supplied as a water-soluble liquid and is used as a foaming and cleansing agent in mild formulations.

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.

Disodium Laureth Sulfosuccinate CAS 39354-45-5

Disodium Laureth Sulfosuccinate is a mild anionic surfactant typically supplied as an aqueous solution for commercial and industrial formulation. Characterized by its excellent foaming properties, stable lather, and low irritation profile, it is widely utilized as a primary or secondary surfactant in the development of sulfate-free systems. In the B2B chemical supply chain, this ingredient is primarily distributed to manufacturers of personal care products, specialized liquid cleaners, and industrial foaming agents. We support bulk procurement requirements with standard liquid packaging, accompanied by essential quality documentation to ensure formulation consistency and compliance. For formulations requiring a lauryl sulfosuccinate rather than an ethoxylated sulfosuccinate, Sodium Lauryl Sulfosuccinate is a related anionic product to compare by active content and application system.

Density (at 25°C)	~ 1.05 – 1.10 g/cm³

Typical Applications

Personal Care Formulation: Acts as a gentle co-surfactant or primary foaming agent in sulfate-free shampoos, facial cleansers, and body washes due to its exceptionally low skin and eye irritation profile.
Specialty Cleaners: Utilized in liquid cleaning formulations that require stable foam generation and mild degreasing capabilities without relying on harsh chemical profiles.
Industrial Foaming Agents: Applied in various manufacturing and processing environments where a consistent, dense, and manageable foam structure is required.

Packaging

As an aqueous solution, this product is typically supplied in liquid-compatible industrial packaging, such as 200kg plastic drums or 1000kg IBC totes, suitable for bulk transport. All containers are securely sealed to prevent leakage, contamination, and moisture loss during transit. Packaging configurations can be arranged according to specific order volumes and regional logistics requirements.

Storage

Store in a cool, dry, and well-ventilated area away from direct sunlight and extreme temperature fluctuations. Keep containers tightly closed when not in use to prevent microbial contamination and evaporation of the water base. It is recommended to store the product at moderate room temperatures to maintain formulation stability and avoid freezing or phase separation.
