Sodium Laureth Sulfate Substitues
Hi guys. Hope your day is going well. I am looking at a shampoo formula that uses 44% Sodium Laureth Sulfate. I don’t have SLS in stock. Is there any other surfactant i can replace it with whether in liquid or powder form? Thanks!

Hi,
44% is not the surfactant active matter, right? It is probably using 44% solution at, let’s say, 10-15%?
It would be probably easier if you tell us what do you have on hand and if you want to replace it with sulfate or non-sulfate.
We can literally name dozens of surfactant - from sodium coco sulfate to “luxurious” ones such as isethionates or taurates.-
Thank you. I have a ton of Decyl Glucoside, Cocamidopropyl Betaine, Sodium Cocoyl Isethionate and Coco- Glucoside

Ok, glucosides are non-ionic .. Cocamidopropyl Betaine is amphoteric and Sodium Cocoyl Isethionate (SCI) is the only anionic on your list.
SCI is a bit harder to work with as it tends to precipitate in solution. Check this forum for some tips and tricks. I would suggest to source more water soluble form of Isethionate - Sodium Cocoyl Methyl Isethionate for example. However if it is for a shampoo, it might be toooo expensive. It is usually used in premium products or face washes as you do not need that much surfactant active level. It is very mild.

You can try a combination of AOS and CAPB that would give you foaming property somewhat close to SLS. If you want to go for sulfate-free try with decyl glucoside and CAPB but that would cost you more also you won’t be able to achieve the good foaming property.
