  • Cocamide MEA blend for cold process formulas

    Posted by Kittykittykitty on August 10, 2015 at 9:35 pm

    I’ve been working on a Cocamide MEA blend for the past few days from some samples I received from Taiwan to make a cold process MEA blend to use in lieu of DEA as a 1:1 alternative for simple hand soaps. DEA is being phased out, as it’s a carcinogen, so I want to get some of our clients switched over ASAP.

    I was heating the Cocamide MEA flakes to 60C to get them to melt and mixing them with the following formula.

    C-MEA 12%

    CAPB 38%

    Water 50%

    My first few attempts at this turned out rather nicely, but suddenly everything I made started coming out like EGDS pearl. Instead of thickening and boosting/stabilizing foam, it just started making all my products pearly.

    Do you think I got some bad MEA? Am I missing something? Any tips/hints?

    No. It is a solubility issue with MEA. Highly dependent on temperature.

    It’s not separating in an aqueous solution, just making the entire thing look opalescent and pearl when disturbed. Is pearling common?

    cocamide DEA is not a carcinogen

    it can form carcinogenic substances in the presence of a very specific type of preservative which is rarely if ever used in cosmetics these days, but it is not carcinogenic in itself

    I apologize for the miscommunication. However, they’re currently banning DEA where I live.
