I’ve never made a soap before but I noticed there is nothing to neutralize the stearic acid since you replaced TEA… Why did you replace TEA with ethanol? What functions do you think they have in common? Ethanol will not neutralize anything.

To get a stearate salt, which will be more transparent in solution (stearic acid by itself is bright white), you need to neutralize your stearic acid with something

I am using SLES 30 % 
stearic acid 13 % 
Myristic acid 6.06 % 
NaOH 3.03 
PG 18 
glycerine 6 
sorbitol 8 
i used 3 % ethanol instead of TEA 
kindly guide me 
as cudnt get enough transparency and my soap is not solidify

You are confusing MARK-UP and MARGIN. I hope you realise that not knowing the fundamental math of business is not a good omen for success…
% MARGIN = 100 x (PROFIT/SALE PRICE) and PROFIT = SALE PRICE - COST PRICE.
Nobody in serious business uses markup.

Gunther said:

@Belassi I got lost, would you mind elaborating on how you got to the 83% figure?

6 times cost = 600%
substracting the 100% cost gives 500% profit, wholly different than 83%

S - Sale
C - Cost
P - Profit
M - Margin

If sale is 6 times more than cost:
S = 6C
P = S - C = 6C - C = 5C
M(%) = 100 x (P/S) = 100 x (5C/6C) = 100 x 5/6 
M(%) = 83.33 

I’m not saying I knew this, just used a little math 

Thank you Belassi

That formula must be a state secret.  There are some ways to dissolve it without (partially) neutralizing it, but again the formula is needed. 
Assuming the concentration of SA is up to 2% you should not have too much issues dissolving it.

actually i use TEA and it is good for litel quantity must be lower then 5% 

In Europe the limit is 2.5%

Thank you em88 for the obvious.

Dear chemicalmatt , Actually it’s a Formulation question, I want to know if there is a difference between them in a formulation?

Why to use Di or Tri in a formulation?

Is There a big difference? How it’s impact the formulation?

Should I look for something else before using one of them?  

Thanks.

I’m almost certain that you are not sure what information do you need exactly. 
First you have to know the pharmaceutical form and application. (guessing is topical).
Second, look for incompatibilities with the other ingredients.
Third, function. 
Both are chelating agents, the biggest difference is the pH these salts induce to your preparation. Disodium EDTA has a pH 4-6 while trisodium EDTA around 9. Also trisodium EDTA is more soluble in water. 

Why not simply list your ingredients and get a more precise help?

[em88]

A. It this actually liquid menthol or is it peppermint essential oil?

I believe you got some papers with that bottle. It should be specified on the bottle as well.

B.  What would be the proper usage rate for this purpose?

I missed the purpose you want to add this EO. If you want the cooling effect, maybe 0.1-0.2% should be enough 

[em88]

@MarkBroussard has a good point. You should make sure the preservative is very well homogenized.

[em88]

As the name says it, trisodium EDTA has one Na+ more. It has a pH slightly higher compared to disodium EDTA 

[em88]

Are you talking about solid preservatives, or liquid?

Thanks for your answer, since I know all the issues with ascorbic acid and water. The plan was to decrease the amount of free water in the formulation. 

Water is not the only factor that reduces the ascorbic acid stability.
We can not help you in terms of guessing the possible undergoing reaction of ascorbic acid and the surfactant without knowing the exact surfactants used in the formulation.
It would be nice to know the pH of the solution and if heating is used during the preparation. 
As presented your formulation is very unusual.

50% glycerin? :worried:

HEC? HPMC?

Too much cocamide DEA 

[em88]

I have never used cocamide DEA due to its bad reputation, and also have seen articles mentioning the adverse effects. I have seen it used in concentrations up to 2%. It should increase the pH as well, but on the other hand 0.1% citric acid does not seem enough. What is the pH of your shampoo?
What kind (concentration) of SLES are you using?
As the other people already said, 1% xanthan gum and 2% NaCl is too much.

[em88]

SLES and HEC should not be used together (based on my experience). 
HEC 1% seems too much, and if you are using hot process (heating HEC at some point) should lead to depolymerization of HEC.

[em88]

I’m sorry, but WTF??? Are you kidding me, why are they still in the market with this? 

[em88]

I like how Belassi gives the replies straight to the point without other ways of interpretation and I totally agree with him. 
You can improve the stability of ascorbic acid, if you increase the pH to 5-6.5.
What about using ascorbate salts? 

[em88]

I don’t know about books, but you can find brochures to start from something. Also have a look at the Perry’s blog, you will find plenty good articles. 

[em88]

@microformulation, that is because you knew to to look for. Still thanks
Have you ever used ABIL® WE 09?

[em88]

@Microformulation I’m sure this is not that case. Anyway, do you mind sharing a few articles regarding emulsification of high amounts of water (over 50%) in w/o emulsion?

[em88]

If water is 75% than, you are making an o/w emulsion and sorbitan oleate will not stabilize the emulsion since it is a w/o emulsifier with low HLB value. 
You should add in your emulsifying system polysorbate as well. caluclate the required HLB for the oil fase and than add 2-5% emulsifying system (polysorbate and sorbitan oleate) in your emulsion. 

[em88]

What is the water %? 
What about adding lanolin?

[em88]

Sodium citrate may help.
