MemberOctober 27, 2022 at 1:28 am in reply to: Which conditioning agent cope with xanthan gumAgree with @Paprik
Use an anionic surfactant and Guar Hydroxypropyltrimonium chloride.
Without anionic surfactant, removing of cationic polymer would be difficult.

MemberOctober 25, 2022 at 1:35 am in reply to: Effect of EGMS on deposition of amodimethicone from shampoo with cationic guarevchem2 said:comments above make sense to me. On an unrelated note, how do you incorporate both xanthan and cationic guar? Are you worried about any long term instability since you have both anionic and cationic polymer in your formulation?I have samples from more than a year ago with no problem.
I add guar first and xanthan last before NACL.

You could even find this happening if you ask them to evaluate the same formula but with different codes. Are they trained panelists? (trained panelists are constantly trained, evaluated and even “calibrated”).Some shampoo bars use Stearic acid which can actually deposit on hair in small amounts (I’ve seen that even with fabric softeners), so theoretically it could happen that your stearate is occupying a place where Amodimethicone was supposed to take. Nevertheless, in shampoos, EGMS is already in solid form (flat sheets of EGMS suspended in the product when used as a pearlizer), which reduced it’s chances of deposition.
Thanks
Yes the number is small and not reliable but that is what i can do right now. -
CzarXavier said:Abdullah said:For viscosity, remove EDTA and reduce fatty alcohols.
I live in AZ which has notoriously bad hard water. Wouldn’t I want to keep the EDTA in this case?
This is a cationic product. I don’t think hard water will be an issue but you should use filtered water anyway and that is not so hard water.
In my experience EDTA increase the viscosity of BTMS a lot.

MemberOctober 21, 2022 at 1:59 am in reply to: Gentle face wash non ionic surfectant percentageYou can use any amount you want but i think 3% SLMI+ 3% CAPB is very enough.

MemberOctober 21, 2022 at 1:43 am in reply to: How an active ingredient becomes OTC or prescription?Here from long time ago people were using viagra commonly without consulting doctor but according to Google search it needs prescription in US. Recently i see that a lot of people here use oral Isotretinoin for their skin smoothness which alsi need prescription in US. I wanted to know if it is ok to use drugs like this without consulting doctor or there is any serious side effects with using these drugs without consulting doctor and maybe for long term.

saeedulfat said:evchem2 said:At 5.5 sodium benzoate is mostly in the salt form which is ineffective as a preservative. Agree with other comments on that you need to switch to a different preservation strategy.
No man the sodium benzoate is 1.25% the ph is 5.5
1.25% sodium benzoate at pH 5.5 gives you 0.05% benzoic acid.
You need at least 0.1% benzoic acid for fungi.
For bacteria you need much more benzoic acid.So sodium benzoate is not enough as preservative at pH 5.5 even if you use 2.5%.

If you want to increase ph above 4.5, i would suggest add another anti fungal too or change preservative again.
