Sodium lauroyl isethionate

Sodium lauroyl isethionate (CAS 7381-01-3), also known commercially as Igepon A, is an anionic surfactant derived from lauric acid and isethionic acid. It delivers effective cleansing, foam generation, and emulsification across personal care and industrial formulations.

In bar soap and syndet formulations, it produces a dense, stable lather while remaining mild enough for sensitive skin products. This is a key factor for formulators targeting premium cleansing bars and specialty soaps.

Body washes, facial cleansers, and shampoos incorporate it to balance foam performance with low irritation profiles. It is highly valued for its ability to maintain skin moisture while providing a thorough clean.

In coatings and adhesive systems, it functions as an emulsifier and dispersing agent. This improves pigment distribution and helps in stabilizing aqueous emulsion systems during the manufacturing process.

Industrial cleaning formulations use it where controlled degreasing and foam management are required in process environments. Its versatility makes it a staple in various heavy-duty and specialty cleaning applications.

The product is supplied primarily as a white to off-white powder or flake. Granulated forms are also available for easier handling in solid formulation processes, reducing dust and improving flowability.

Cosmetic-grade material is the most common commercial specification, typically meeting purity requirements aligned with personal care industry standards. This ensures safety and consistency for high-end consumer goods.

Technical-grade material is available for industrial surfactant and coating applications where cosmetic compliance is not required. This provides a cost-effective solution for large-scale manufacturing and chemical processing.
