Sodium lauroyl methyl isethionate

Sodium lauroyl methyl isethionate

Sodium Lauroyl Methyl Isethionate, or SLMI, is a mild anionic surfactant derived from coconut oil and is sulfate-free. Unlike SCI (Sodium Cocoyl Isethionate), which creates opaque products, SLMI has excellent water solubility, making it possible to create transparent, sulfate-free shampoo formulations. It is often used in conjunction with CAPB.
SLMI is produced by ethoxylation, making it an environmentally unfriendly ingredient. It is prohibited in the COSMOS specifications.

For users, it is the possible traces of ethylene oxide and 1,4 dioxane, these two ingredients being carcinogenic, teratogenic, irritant and mutagenic, which pose a problem.

These functions:

  • Cleaning agent: Helps keep a surface clean
  • Surfactant: Reduces the surface tension of cosmetics and contributes to the even distribution of the product during use

The manufacture of SLMI (sodium lauroyl methyl isethionate) requires carboxylic acid which is naturally present in coconut but also sodium 2-methyl-2-hydroxyethane sulfonate and sodium 1-methyl-2-. These two ingredients are produced using propylene or butylene oxide with sodium bisulfite.

  • Propylene oxide is produced from propylene (which itself is derived from ethylene or propene, which are hydrocarbons) either by hydrochlorination or by co-oxidation of ethylbenzene and isobutane. There are two other less common production methods: co-oxidation of cumene hydroperoxide and isobutane and Hydrogen peroxide to propylene oxide (HPPO), which uses oxygen peroxide to oxidize propylene.
  • •Butylene oxide is produced during the oxidation of 1-butene. The latter comes from petroleum refining (more precisely from C4 gases or by dimerization of ethylene
