Cocamide MIPA - Cosmetic Science Talk

Cocamide MIPA

So it's time to say goodbye to good ol' banned DEA and find a good replacement for shampoo and hand soap formulas. I've been doing research and asking suppliers, and the most obvious and simple replacement is MEA. But what im hearing is that most customers are going back to DEA mostly to avoid heating. I'm not that cheap :P and I like to improve my formulas if I can, so even if it hasn't been banned here yet I want to find a permanent replacement long before this happens.

Reading around I saw a manufacturers paper recommending MIPA, and according to them it had the same performance regarding viscosity, foaming, emulsifying, etc. The downsides, is more expensive and needs more heat. About 50°C.

Because of this it's been hard to get a sample, most providers are not selling it, and i would have to buy a couple of bags to justify importing it just to make a tiny lab test.

So is any of you currently using it or have you done any trials?.  Do you guys consider it a good replacement or do you consider there are others that would perform better?. I'd like to know how it behaves, if it's hard to incorporate, if it's cost/effective, foaming and cleaning capacity, any input your personal experience could provide is much appreciated.

    I've used ColaMid CMPA from Colonial (CocamideMIPA) and it works just fine, but you do have to heat to dissolve it.

    However, I find it easier to used StepanBlend FF40 (Sodium C14-16 Olefin Sulfonate (and) CocamideMIPA (and) Cocamidopropyl Betaine) which is a fine liquid blend with MIPA and you don't have to heat.

  • About 1.5% maximum. Easy to use. Improves foam and thickening.

  • So it's easy to incorporate once dissolved?. Won't solidify if I incorporate it SLES at RT for instance?.

    If it is such a good replacement why it hasn't been seen on shampoos or soaps?. I tend to distrust if I don't see it on a shelf, if the leading companies aren't using it there must be a reason.
  • Won't solidify if I incorporate it SLES at RT for instance?
    It is hot process only. Must be at 75C or above and must be thoroughly mixed. Many products have it.

  • We have switched to a paste version of Cocamide MEA which can be incorporated in cold process applications with no real problems.  Maybe you could investigate this instead.
  • So that's the catch, keeping a batch at 75° is expensive and I'd need to modify the reactor. I was told that 50° or 55° would be enough. That's the problem with sales guys, they will say what you wanna hear.

    @ozgirl I will look into it, I was thinking I could heat up MEA with water and store the paste . Are you buying it already as a paste or you are doing it yourself?.
  • The melting point is 63C but from my experience, you want it a fair bit hotter than that or you risk getting a hazy product after cool down.

  • @DAS We buy the paste. I think it is a Chem Rez product (We buy through a distributor).
