It depends. If nothing in your formula needs heat them it will be ok.
-
I make a 20% EDTA solution and use that.
Use the preservative at highest amount allowed
-
Let us help you.
What other emulsifiers and surfactants do you have?
Yes, surfactants that we use in shampoo.
-
Po65 has 34% APG surfactant
-
What is your pH and what is your target viscosity?
Poly glyceryl 4 laurate creates very low viscosity emulsions.
-
They are the same
-
You mean those white things?
Can you explain your preparation method and pH!
Maybe you are not melting them properly before homogenization.
-
In my opinion the best option is a clarifying shampoo + a conditioner
-
And add 0.2% EDTA too
-
1%( 0.2% active)
-
If your emulsifiers need heat then you should heat the oil phase too.
It is only 5%. What is the benefit of not heating it?
-
It is cold and hot water soluble. Add 1% active surfactant in water phase. Some of them have high pH so adjust pH.<div>
You can add olivem in oil or water phase and see which one do you like most.

Ok
Reduce 1% Olivem and add 1% Caprylyl/Capryl Glucosides and see if the viscosity has dropped enough.
-
Sorry, my mistake. I wrote it the other way around. It is 71% water and 29% total solids. 12% glycerin, 4% emulsifier and only 0.6% benzyl alcohol was included as preservative in example formulas
-
I saw a patent and It had 12% glycerin and ~25% water in that cationic emulsion.
-
Yes
-
They have 12% glycerin.
-
pH 4.3 is better than 5.
Why are you not using some petrolatum and glycerin instead of those butters?
Make a batch with 10% petrolatum and 10% glycerin and see how it works for very dry skin.

I made two samples, one 10% STPP in hot and one in cold water. The one in hot water dissolved properly with low speed mixing but the one with cold water STPP didn’t dissolve until i heated it a bit.
These samples were made in glass pot. Surprisingly this time after adding sodium hydroxide, it didn’t precipitate.
Also, after adding 10% STPP in water, pH was around 7. Is it normal?
-
ALS, sci, scg and an amphoteric
-
No it will not and it will be difficult to thicken too.
-
To what degree c you heat them and what is the homogenization speed and batch size?
-
Does is just feel nice or increase the stability too?
-
In my experience LGN emulsions with cationic emulsifiers like BTMS or BTAC are very stable without any water phase stabilizer.
@chemicalmatt what do you think about cationic guar for this purpose?

Thanks
