Difference between SLI and SLMI?

Hi All!

I was wondering if anyone has worked with both surfactants, SLI (Sodium Lauroyl Isethionate) and SLMI (Sodium Lauroyl Methyl Isethionate) and can describe the differences? the application would be for shampoo.

I’ve been working with SLMI in solid, flake form and it works great, however it is sold by very few suppliers, and is EXTREMELY costly...

I havent worked with SLI, but based on the comparative low cost and the fact that it is still derived from coconut i think i want to give it a try.

thoughts?

thanks,
Steve

  • SLMI is easily thickened with salt, while SLI does not thicken with salt. Probably going to need to use other secondary surfactants, probably amides
  • ok interesting! yes my formula also uses other surfactants...  thanks so much for the reply!!!

  • SLI may not be water soluble like SCI.
