Ah I hadn’t even thought of the difference between MIT and CMIT. I lumped them together in my thought because the products I’ve tried had both together but now really curious if it’s only one that I *suspect* difficulty with. Neither of these have bothered me in the past and I used them for years without issue, so I’m not even sure the preservatives are the problem.

I know it’s been so many questions and miles to go with learning here. Is there a particular more water soluble preservative you’d recommend to use with PE 9010 if I do trials with it?

[Chris45]

Yes thanks for the percentage recommendation. The edta does confuse me a bit where it is recommended by Schulke in the conditioner doc attached above, but then again it also looks like there is sufficient coverage with 1% PE 9010 and no edta.

Thank you Phil! Where PE 9010 has both, would that mean an additional preservative wouldn’t be necessary to cover any potential gaps in a simple emulsion like this?

This is extremely helpful, thank you Paprik. I’ll start with Germall and see how my scalp does. A much better option than risking something not properly preserved I’m sure & it will allow me to get started while learning more. I greatly appreciate your input!

Ah interesting!

1) I had thought a chelator was helpful to boost the preservative effectiveness. I didn’t realize it would actually work against it here causing insoluabilty problems. Thanks for this.

2) Yes this for my own use but I have longer, very tangle prone hair and typically use conditioner on my scalp as well, both for dryness and tangles.

3) If mixed into the water phase, would that eliminate the need for using glycerin/propanediol? I’d like to start with just a basic emulsion so I can better judge how the addition of ingredients work for me.

4) Any thoughts on what to use to support Euxyl or would you recommend something different altogether?

Thanks again for sharing.

Thanks Phil. I’m avoiding the MIT preservatives right now unfortunately. I suspect they are contributing to my itchy scalp issue (I can’t be 100% sure about this but have had improvement since avoiding commercial products using them). Is there another preservative you’d recommend to use in addition to Euxyl or in place of? I was leaning toward it because it’s used in 2 products I tried that I’ve tolerated better than others, but sure open to your thoughts.

[Chris45]

Thank you for this Yuno. So you use Euxyl at 1% of your water phase when you work with it? Do you happen to know how much glycerin/propanediol would be required in order to make sure the preservative would stay soluable if using it at cool down in an emulsion like this?
