Isethionates

Hello :),

I'm trying to work with Isethionates. Does anyone have any experience? 
I've been recommended to try Sodium Lauroyl Methyl Isethionate. Unfortunately I couldn't find this here in NZ, but I could find Sodium Cocoyl Methyl Isethionate. I can't find what is the main difference. Or can I consider this to be fairly similar? 

Also, it's supposed to create a clear gel. I've added cocamidopropyl betaine, not only it took over night to thicken ( is that common with Isethionates? ), but it turned into white, slimy consistency. Not very appealing to my eyes. Does that depend on the amount of CAPB? Or would you skip it and used some HEC instead to thicken it?

Thank you! :smile:

  • I would also be interested in the difference between SLMI and SCMI. From the little information I've been able to find I believe they are fairly similar but don't really know.

    I don't know about the slimy consistency, but what I do know is that the opaque opalescence of SLMI in water completely goes at a lower pH of around 5.

    Hello Agate, 

    thank you for your reply. Yeah, if I'm looking for SCMI, I always get results for SLMI. So I would also guess they must be very similar. Hopefully someone else will have more info about that :)

    Hmm, so you reckon it would be the pH? I will try to increase it and see. :) Thanks for the tip!
  • What was the formula or just the ingredients you used?? 
    That isethionate would be fine! It’s usually what you mix it with & pH that turn it opaque or white!! 
    Did you use any aloe Vera?

    Hello Dr.,

    thank you for your reply. Frankly, I was just trying to mix water, SCMI and CAPB. I just wanted to see how it goes. From top of my head, I used 8% SCMI and 4% CAPB. I did not even bother with any preservative. (I'm aware it may have an impact later on the formula.)

    Next day I was trying add Glycerin and I adjusted SCMI to 10% and kept CAPB at 4%. Glycerin 5%. It barely thickened at all. So I guess I will need to play with the inputs of surfactants. 
    And also check and adjust the pH. Althought, I would never imagine, it would go lower than 6 by itself.

    Here is some information regarding formulating with SLMI that might help you with the SCMI.

    Thank you for that :) Haven't seen this leaflet yet, but found different ones.
