⭐ Sodium Laureth-3 Sulfosuccinate 

Sodium Laureth-3 Sulfosuccinate (SL3SS) is a high-performance anionic surfactant known for its excellent detergency, emulsifying power, dispersing ability, wetting action, and solubilizing capability. It provides very low irritation, outstanding compatibility with a wide range of surfactants, and can significantly reduce the irritation level of other ingredients in a formulation.

SL3SS produces fine, dense, and stable foam, making it ideal for mild cleansing systems. Its low surface tension, strong calcium-soap dispersibility, and excellent hard-water resistance ensure superior performance across personal care and household formulations. It offers moderate detergency, very low degreasing effect, and easy-rinse properties without leaving a slippery residue on skin.

Additional Industry Insights 

Sodium Laureth-3 Sulfosuccinate is widely recognized as a premium mild surfactant used in sulfate-free and sensitive-skin product lines due to its dermatological tolerance. Compared with traditional sulfates, SL3SS provides:

• Enhanced skin mildness, making it suitable for baby care and sensitive-skin cleansers

• Rich, creamy foam profile, often used to upgrade sensory experience

• High compatibility with amphoteric and nonionic surfactants (e.g., CAPB, APG, AOS)

• Improved stability in acidic to neutral formulations

• Better cleansing comfort with minimal disruption to the skin barrier

Typical Applications

SL3SS is widely used in:

• Sulfate-free shampoos

• Gentle facial cleansers

• Shower gels and bath foams

• Baby wash and sensitive-skin products

• Premium hand soaps

• Cream-to-foam formulations

• Mild cleansing systems in cosmetics and dermatological products

Because of its mildness, easy biodegradability, and excellent sensorial profile, SL3SS is often chosen by manufacturers developing premium or clean-beauty formulations.
