  • Replace SLS by sodium cocoate

    Posted by Dilfre on February 8, 2017 at 1:03 am

    Can sodium cocoate replace SLS? SLS prices are rising like rockets here and we are thinking in replace it in some extend in our formulas of liquid shampoo by the relatively cheep and abundant coconut oil. somebody have try something like that? thanks in advance.

    Not really, no. The fundamental problem remains of soap scum being formed by reaction with salts in the water. You might get away with a partial addition, especially if you used a chelator, but chelators cost more than SLS anyway.. 
    Can’t you get SLES, by the way? SLS is pretty harsh. CAPB is really cheap and foams well, many baby shampoos use nothing but, so maybe you should increase the proportion of CAPB?

    You was right Belasi, there is a separation, I guess the oil fractions with higher molecular weight. I will Try CAPB.

    The reason SLS prices are rising is the increasing price of coconut oil. Plantations took a big hit a couple years back due to tropical storms and the effect of that, combined with big increase in use in food products, is driving prices way up.

    Sodium cocoate is also a poor replacement from an irritation standpoint. You can’t formulate at physiological pH because it’s mostly free fatty acid at that point. Clear systems require at minimum a pH 8-9, which is quite harsh to skin and especially eyes.
