Disodium laureth sulfate is on the label of a shampoo that is sold in Brazil, so they must have spelled it wrong. Thank you so much for sharing your knowledge with me.

@Perry I understood! :smiley: Thank you a lot for your assistance!

@Perry Hm, I got it! Why do these agents interfere with cleaning?

@Perry Thanks so much for your help again. I really appreciate it. I’ve been researching some more and I have one more question: do you think that the concentrations of the amphoteric surfactants used in those formulas might aid their cleansing power? It seems that in Brazil they are allowed to use 2.5% concentration of those ingredients. Does that make any difference?

@Perry Hi, Perry! Thanks a lot for your help. :blush:

Those two formulas that I’ve posted are from products that are sold in Brazil as “washing” conditioners, or “co-wash”, as some people call it. They are meant to be used by people who don’t want to use strong surfactants/sulfates in their hair, like SLS and isethionates, etc. So they basically wash their hair with this.

But my main concern is: some people may be using other hair products like lotions and creams that might contain water-insoluble silicones, like dimethicone. Since they are not using any strong surfactant on their washing routine, will those amphoterics and non-ionics surfactants like “cocobetaine and decyl glucoside” be able to remove the water-insoluble silicones traces left by other products?

Thank you very much for the explanation, @Perry and @LincsChemist.
