  • What’s the difference between Disodium Laureth sulfate and Sodium Laureth sulfate?

    Hi, good afternoon! If I only analyze the surfactants and their cleaning power, if I have two solutions: one with Disodium Laureth sulfate and the other with Sodium laureth sulfate, both with the same amount, which one will be more efficient?

    Disodium Laureth Sulfate doesn’t exist, so Sodium Laureth Sulfate will work better.

    There is, however, disodium laureth sulfosuccinate in case that’s what you mean. It’s exceptionally mild and as per some suppliers is well tolerated by mucus membranes (I would probably agree with this claim based on my anecdotal experience). Regarding what is better… SLES is much more multifunctional. Disodium laureth sulfosuccinate doesn’t like low ph and is very difficult to thicken (if someone has tips please share). It also doesn’t cleanse as well as SLES does.

    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.

    Yes, likely just a spelling error. My guess (based on the other ingredients) it should be Sodium Laureth Sulfate.
