Add 50g water to 50g NAOH and continue mixing it to reach more water to more NAOH quickly and see.

@PhilGeis sure but if there is any known incompatibility it is better to know and change that i ingredient or preservation system.

@Pharma @PhilGeis any comments on this.
Lotioncrafter says: Benzoic acid is inactivated by non-ionic surfactant.
Makingcosmetics says: Phenoxyethanol should not be used in formulas containing HE-cellulose or non-ionic surfactants.
One another website said phenoxyethanol is deactivated by highly ethoxylated surfactants. Does this include SLES or ALES?
Thanks in advance

@PhilGeis thanks

@Pharma got it thanks
-
@PhilGeis thanks a lot
-
@PhilGeis sorry buy i didn’t get your point “assuming you obtain solution of addition”. Can you explain it a bit more!
-
You can use any brand. I purchase locally and forgot the manufacturer name but it was 200000 mpas viscosity.
-
I don’t know the reason but i know APGs at high amounts are not compatible with cellulose. Also decyl Glucoside is very hard to thicken but lauryl is very easy.
-
@Anca_Formulator thanks for information.
Do you know what is the percentage of each ingredient in Polyaquol? -
I am interested in Polyaquol 2W for high viscosity lotion, can it make it?
Do you have MSDS of the product?
Can you share it? -
Yes it is very stable.
Just use %0.3 xanthan gum or some carbomer in water phase.
And it is also liquid crystal. -
Use HPMC instead of HEC.
Reduce decyl Glucoside to %1 or replace it with lauryl Glucoside.
%10 decyl Glucoside is very difficult to thicken -
High viscosity HPMC also works as thickner in Shampoo

@PhilGeis Formalin is %37 formaldehyde in water, is that %37 free formaldehyde?
-
@PhilGeis thanks
The upper limit for DMDM hydantoin is %0.6, so why warning above %0.05?Finished products containing DMDMH must be labeled with the
warning “contains formaldehyde” if the (free) formaldehydeconcentration exceeds 0.05% -
@Bill_Toge EDTA is also anionic and not compatible with cationic surfactants. So how does that effect PQ10?
-
@RedCoast i don’t think it was fume. The smell was lavender eo that i was adding. From just smelling the Product there was no problem but after applying it to face or hand i was felling something is not good and there was some tightness my chest. No irritation. Then When i was washing my hand or face after from the Product, the problem was solved.
I was adding EDTA at first and HCl at cool down. One day i decided to add it first at water face because it was powder not liquid,i first added EDTA then when i added HCl, a white powder like thing formed on top of water that was not soluble in water. Then i made another batch without EDTA and it was easily soluble in hot water. So i figured these two are not compatible.Then I made two batches separately one with EDTA and another preservative and one with HCl and both were amazing with no problem.
Then i checked it’s compatibility with each ingredient, it was not compatible with citric acid too.

Mixing incompatible ingredients doesn’t mean the emulsion should always break. It means those ingredients will not do what you want them to do and may be some other side effects.
I was once mixing EDTA vs Ethyl Lauroyl Arginate HCl which are incompatible in emulsions. The emulsions were stable but i was felling some shortness of breath when i was applying the lotion to my body. When i found that these two are incompatible, removing each of it made a beautiful emulsion without any problem.

Polyglyceryl 4 Laurate makes very thin emulsion
-
For moisturization add %20 glycerin and %5 petrolatum. This works better than anything else you can compare to. The manage the aesthetics.
-
@Pharma thanks
-
Thanks @Pharma
It is %0.2 EDTA or %2 Sodium citrate.
I got the picture. As Just when the binding is very fast is the chelation time in seconds, minutes or what approximately? And also when when it takes a while, how much? -
@PhilGeis thanks

High amount of humectants will make your skin drier if you don’t have occlusive.
