Use HPMC instead of HEC.
Reduce decyl Glucoside to %1 or replace it with lauryl Glucoside. 
%10 decyl Glucoside is very difficult to thicken

[Abdullah]

High viscosity HPMC also works as thickner in Shampoo

[Abdullah]

@PhilGeis Formalin is %37 formaldehyde in water, is that %37 free formaldehyde? 

[Abdullah]

@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) formaldehyde

concentration exceeds 0.05%

@Bill_Toge EDTA is also anionic and not compatible with cationic surfactants. So how does that effect PQ10? 

[Abdullah]

@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.

[Abdullah]

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

[Abdullah]

For moisturization add %20 glycerin and %5 petrolatum. This works better than anything else you can compare to. The manage the aesthetics.

[Abdullah]

@Pharma thanks

[Abdullah]

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? 

[Abdullah]

@PhilGeis thanks

[Abdullah]

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

[Abdullah]

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

[Abdullah]

@PhilGeis thank you too!
How about %0.3 Glyceryl Caprylate with %0.05 kathon in this formula? 

[Abdullah]

SLI may not be water soluble like SCI.

[Abdullah]

High amount of surfactants also don’t need preservative.
What percentage of surfactants do you use in your Shampoo bar?

[Abdullah]

@ngarayeva001 thanks a lot

[Abdullah]

@chemicalmatt of course i want to maintain the pearlescence while sitting still on a store shelf.

I am using %9 SLES and%2 CAPB actives. Is that enough? 

Is adding HPMC, PQ10 or cationic guar enough as suspending agent or not?

[Abdullah]

I don’t know how how are calculating the HLB for 4 emulsifiers in a system.

Use Steareth-21 and Steareth-2 as emulsifiers, calculate the HLB, total %2-4 emulsifier. 
Use Cetyl Alcohol and Stearyl Alcohol as oil phase stabilizer and %0.3 xanthan gum as oil phase stabilizer. 

[Abdullah]

@PhilGeis do you mean use kathon at %0.05 or %0.5?

What percentage of sodium benzoate should be used with %0.05 kathon in this Shampoo formula?
SLES
CAPB
Glycol distearate %1
PQ10

NACL
Tetrasodium EDTA %0.2
pH 5

[Abdullah]

@klangridge hi 
Thanks for sharing your opinions.

My Shampoo is opaque. What is the difference between macroemulsion and microemulsions specially for Amodimethicone emulsion?

Currently i am using NACL to thicken the system. Is that enough for suspension of Amodimethicone in shampoo?

If not, would HPMC, cationic guar or PQ10 stabilize the suspension?

[Abdullah]

@ngarayeva001 would it increase the viscosity or decrease it? 

I want to use it for it’s conditioning effect. 

[Abdullah]

Don’t use them and see what happens

[Abdullah]

What is the shampoo formula?
