Try a very mild alkaline neutralisation if your formulation isn’t averse to it though you can always adjust the pH at the end. I have observed the same and realised that an immediate and a very mild alkaline neutralisation will help you get a very uniform dispersion. I add it in my hot process shampoo during cool down phase mixed with Methocel 40-202, no issues at all.

No, GHTC first. Neutralize with citric acid to pH 4 and then SLES. Add the remaining surfactants and everything else once the surfactant mix is clear.
-
Amit what is FW; also when you use the cationic guar an acid neutralisation is required. Have you done it all?
Adding all the surfactants won’t be advisable as SLES needs to be dispersed/dissolved completely in the batch before you add other surfactants. As Perry mentioned, in such a formula salt can easily be the thickener. -
As per my old knowledge (not sure how accurately it holds now), oil free claims are for paraffin oil free formulations.
-
Point is that benzalkonium chloride is cationic and SLES/LABSA anionic. Anything you do to adjust the formula isn’t going to work unless you take out the quat.
-
SLES, LABSA anionic, BKC cationic. End of.

I see triethanolamine soap as a possible source which probably wasn’t quite visible initially. Now the foam/bubbles rising to the surface.
-
Marketing stories can be built around 0.01% as well honestly. As for dimethicone replacement, there are options with water solubility and you can easily go that route.
-
I will be very shocked if it didn’t separate with that amount of dimethicone and Argan oil. Plus why 1% panthenol when it will be washed away. And last but not the least, why that much essential oil??
-
To the same formulation, add around 6-8% SLES. Use sodium chloride to adjust the viscosity then as needed.

Think the guy got confused between witch hazel and witchcraft ??
-
It’s more like a titration and you would have to add it gradually to get the desired pH.
-
@Will I meant i have used Acudyne 1000 but in a water based hair gel. Never tried a product you are talking of.
-
I have used Acudyne 1000 but in a hair gel with Aculyn 88. I must say that the hold property of this combination is unmatchable.
-
Make a separate solution from batch water and add it.
-
Bill very well said, explained the same to the customer. Just needed to add some Acusol 882 from our portfolio ?
-
0.5% carbomer (I assume it is 940) by itself gives a very thick gel and I believe it will be sufficient to give you a very stable emulsion with the suspended dimwthicone. Though I haven’t tried adding 2%.
-
TEA will neutralize the FA & carbomer both.
-
I would say more likely suspended with the help of carbomer, that formulation seems to be having a higher viscosity with that much of carbomer.
-
Mark I have a product in my lab given by a customer and which is a hair straightener formula. He said it is from Brazil and the straightening effect remains for 3-6 months. I was told to develop it, checked the pH. It was below 1 and I excused myself.
-
Cetyl Alcohol is a big help in such formulations in combination with your cetostearyl alcohol.
-
Try adding the the fixative after neutralization and see how it comes out. If still unclear and gritty, then there is an issue with your fixative. Or as @ngarayeva001 pointed out about ETDA.
-
How about simply using PEG-150 Distearate???
-
It’s good to know about your well being @johnb and I couldn’t agree more with what you have summed up above. Sometimes you know people through the writings and posts and you just want to know if they are doing fine. @Bobzchemist used to post regularly as well and few of the members here have contributed in a manner that we feel lucky to have gone through those posts.
Stay well and stay blessed. And a big thanks to @Perry for an initiative that is unparalleled and is almost like an institution itself. -
Concur with @Doreen, I doubt if that would be possible without increasing the carbomer. I am not sure which PEG you are referring to here and how it can build up viscosity.
