MemberMay 2, 2021 at 12:54 am in reply to: Phenoxyethanol and sodium benzoate incompatibility@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 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 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?

MemberApril 27, 2021 at 12:09 pm in reply to: Suggestions on how to make this formula more moisturizing and less tacky@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.

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

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? -

Formalin is available locally and very inexpensive. I thought if i make a preservative system around that it would be great.
