Fizzy emulsion - ways to avoid fizz

Posted by Lisani on December 15, 2018 at 11:35 pm

Hello everyone,

i am am having problem of emulsion fizz, means after some time, it release gases when I open the package, and sometimes it feels like the bottle is about to explode.
The emulsion contains fatty acids, silicones and Glyoxylic Acid (50% solution) in 40%.
Even if the emulsion is thick, it forms a foam after some time (around 3-4 days).

I am using TMS-50 as an emulsifier, in 2%.

is there any way to avoid this?

Thanks for the help,

Aaron

It sounds as if you are combining an organic acid with a cationic emulsifier? Is that so?

That is correct @Belassi, is there any option to keep this emulsifier and avoid fizz?

I don’t see that it would be possible, you’re basically making a bath bomb.

Thanks @Belassi, can you recommend an alternative emulsifier that can be suitable for this formulation? I chose the TMS-50 due to its fantastic conditioning properties..

Frankly I think you are trying to do too much with one product. You would be better off designing two different products. “First use package A, then use package B”. You cannot mix anionics with cationics except under very limited circumstances.

Chemistry… These are the situations where Chem 101 come in handy.

Glyoxylic Acid (in combination with TMS) would be the primary suspect using the information given.
Alternatively, find a driven salesperson, call it fizzy emulsion and you might get rich!

I think you can first react glyoxylic acid with an alkaline base like Sodium or Potassium hydroxide to make a glyoxylate salt. That should prevent it from reacting with BTMS.

It looks like glyoxylate salts retain their hair straightening activity.

More to the point, even before Gunther weighed in, I wondered how did you get around that Henkel patent? I am curious about that. Oh and yeah, drop the behenyl quat for sure.

Thanks everyone for the answers, I replaced the TMS with a non ionic emulsifier (there are many options) and the problem solved.
thanks again ??

I actually wondered what’s so new about that patent?
Hasn’t Sodium glyoxylate used before for hair straightening?

Negative, Gunther. Henkel did scoop other chemists on that function though. It was used in textiles before, just like the alkaline relaxers were before somebody got the notion to use on human keratin. Makes a good case for cross-pollination of industries and ideas.
