which ingredients are wrong together in the my formulation?
I am making a facial cleanser i used Xanthan gum, sodium chloride, C10-30 alkyl acrylate crosspolymer and Disodium EDTA for thickening and other purpose but i just found that there is on or two ingredients that can not fit together i am not sure but i think it’s the C10-30 alkyl acrylate crosspolymer and xanthan gum.
any advice will be appreciated

Is this a trick question?
Remove the salt. Polymerics generally do not appreciate electrolytes. Why is it even in there?
-
no dear, this is what i am really straggling with.

As mentioned, get rid of the Sodium Chloride. You may have seen it addressed for thickening, but that is with select surfactants for the most part. That is a topic far too broad to cover here.
You may not need the carbomer and the Xanthan gum. They are used in some cases together to potentiate each other but I don’t believe that this is the case here. I would strongly suggest that you do some independent study on carbomers and natural gums. I am not disparaging, but they are large areas of study and are far beyond the scope of blog learning.
I am not sure how you feel Disodium EDTA is thickening. It “could” be an issue with some carbomers.
Good luck formulating. There are lots of great posts in the group if you use the search function and keywords.

but the question is how to solve C10-30 alkyl acrylate crosspolymer in water even if we remove sodium chloride
i made another sample and the result is the same with pervious which was containing sodium chloride

Did you list ALL of your ingredients? Electrolytes come in many forms.
-
1- water 2- C10-30 alkyl acrylate 3-Xanthan gum 4-sodium chloride 5- Disodium EDTA 6- glycerin 7- cocamidopropyl betaine 7- capryl glycoside 8-Disodium cocoyl glutamate 9- sodium cocoyl glucinate 10- sodium louroyl methyl isethinoate 11- shea oil 12- stearic acid 13- glyceryl stearate 14- cocoglucoside& glyceryl oleate blend 15- pentylene glycol.
these are the ingredients list any advice, replacement, so will be appreciated

À lot of correction can be made, there is no need to slat, you need to neutralise your carbomer, there is no need to two thickener, a lot of surfactants wich will increase the price of your product without any intereststing gain.
-
can you suggest me what should i remove?
-
CAPB with other one surfactant make the job, wich is the best? you shlould work for that.

Are you neutralizing the C10-30 Alkyl Acrylates?
-
no i thought there is lots of ingredients with high Ph may then can do this, is it wrong?
-
Yes, absolutely. It would be best to track the neutralization with a calibrated pH meter, not strips. Your “assumption” that the other items will neutralize the product is 100% incorrect.
-
thank you so much dear!
can you recommend me some good neutralizer?
-
i am using Triethanolamine in my primer i thought i should use it in this formulation as well but in my primer we add this when temperature decrease up to 40 C, in this formulation i am afraid if i add it in the beginning to neutralize and then add other ingredients to heat them this Triethanolamine lose its properties.
please give me hand in this regard
-
This is far too wide of a topic for a blog and should entail some study on your own. I would suggest reading some Lubrizol documents on neutralizing carbomer and other sources. 3V makes some superior products as well. I believe in the value of self-guided research as it makes you a better chemist. It’s the standard I hold on any techs I train as well.
