Okay cool. Thanks for all the help

@Pharma thanks for the information. Have you ever used it before?
@chemicalmatt thank you. I trying to get a full explanation from the supplier.

Interesting question. I don’t have an answer for you but would love to hear others perspectives.

@MarkBroussard @ngarayeva001 I am talking about in general. What I mean is if you use a base to create TEA Stearate or Sodium Stearate, which is anionic as has been mentioned, how would you calculate the quantity of a secondary non-ionic emulsifier? Would that be trial and error? Also would the HLB of that non-ionic emulsifier even matter when being paired with an anionic emulsifier?
thanks for all the comments and help.

@Pharma basically the confusing part is that there many cream products or formulas that are using Stearic Acid as a co Emulsifier are using a secondary emulsifier with a high HLB value such as Ceteareth 20. From my calculations I haven’t seen one where it would balance. Or am I missing something totally here?
-
@Pharma thanks for the formula. I do know how to work out HLB but have found Stearic Acid particularly confusing.
How would one balance the HLB when using a coemulsifier like Ceteareth 20 which has a high HLB?
-
@Bill_Toge i thought that was probably the case. What is the best way of working out how much of the secondary surfactant is needed then? Or is that just trial and error?

Thanks for all the comments and help. Extremely helpful. Thank you

So I have managed to source some Dimethicone. Which do you recommend DC200/100 or DC200/350?
Thoughts on Stearic Acid and Cetyl Alcohol? I have found Stearic Acid tends to give a nice texture but for some reason, I have found stability a challenge when using it.

That is seriously helpful. Thank you Ngarayeva001.
I have been waiting for my supply of Tocopherol to come and that’s why I didn’t add it (Still 10 weeks away). I only have Tocopherol Acetate at the moment. I have the Glyceryl Stearate / Peg-100 Stearate Emulsifier so I will give that a try and see how that turns out. Great suggestion. I also don’t have a supplier of Dimethicone at the moment so I will start trying to source some.
Lastly, I have been testing Carbomer 940 with some positive results. Would that be worth using or should I try Xanthan Gum?
