Sodium lauroyl Methyl Isethionate CAS No.: 928663-45-0
In recent years, there has been a growing demand for milder, gentler, and more environmentally-friendly ingredients in personal care products. Sodium lauroyl Methyl Isethionate is one such ingredient that has gained popularity in the skincare and hair care industry for its excellent cleansing properties, mildness, and biodegradability.
Origin
Lauric acid from coconuts and sodium isethionate can be esterified to create sodium lauroyl isethionate (SLI) in a single step. Then, sodium lauroyl isethionate is converted into sodium lauroyl methyl isethionate (SLMI) by adding a methyl group.
The water soluble, sulfate-free surfactant sodium lauroyl methyl isethionate is derived from coconut. This ingredient, which should not be confused with the similarly named sodium lauryl sulphate, is a remarkably mild surfactant and is regarded as one of the safest available. It is found at concentration of 0.009% in leave-on products and 0.64-10.1% in rinse-off products.
1.Skin care: As a result of its excellent formulary compatibility, it is well-known to work well with other ingredients in products like body washes and facial cleansers.
2.Hair care: It is a safe alternative to sulfates. Unlike SCI (sodium cocoyl isethionate) which makes it possible to create opaque products, SLMI has excellent solubility in water, and therefore makes it possible to create sulfate-free, transparent shampoo formulations. It is often used in conjunction with CAPB.
Characteristics
