I need your help in makin soap base face wash
I making soap base face wash but its not have enough foaming and its foaming become decreased day by day
plz give me the solution
Formula:
Stearic acid 14 %
Myristic acid 7.5 %
EGDS 2 %
CMC 0.5%
Glycerine 2%
SLES 6%
SLS 2%
Cocobetain 2%
KoH 4%
Phenoxyethanol 0.5%
Water to make 100%
Plz tell me the solution or give me a proper formulation -

Usman with that much fatty acids nothing would foam. Increase the SLES & SLS by 2-3 times each and reduce each fatty acid by 50% or 2/3rd. Try and come back with your observation.
-
Put the fatty acids into soapcalc.net and calculate the amount of KOH to saponify them. Do that first and then add the result to the rest.
HOWEVER I have to say that I have been down this route and I do not recommend it. Go either soap based or synthetic. -
Agree with @Belassi, it’s kinda complicated stuff and the stability versus performance is a big trouble.
-
The percentage of KOH is approximately correct, but I suspect that if not precombined, the reaction time would be very lengthy. Not only that, you end up with a pH of about 9 to 10.
-
Why not saponify an oil, for example extra virgin olive oil, and leave out all the other stuff?
We do this and it is a huge success for our own brand and the other OEM brands we manufacture for.

Thanks to all for helping
Sir i have tried again as following
Myristic acid 8 %
Stearic acid 12%
SLS 2%
SLES 5 %
Cocobetain 4%
K-D 2%
KoH 4.5%
PG 1%
Glycerine 2%
CMC O.5 %
PH=8
The foaming is increased but it become separate after 10 days 2 layers apeared
Plz help me with a stable formulation please i m so worried -
While Potassium myristate (from reacting Myristic acid + KOH) seems to be a bit soluble, Potassium stearate is likely insoluble.
Please read the study
The solubility of sodium and potassium soaps and the phase diagrams of aqueous potassium soapsThe only soaps that are even moderately soluble at room temperature are potassium laurate, myristate, and oleate, the potassium salt of acids from coconut oil, and the sodium oleate. The other sodium and potassium soaps of the saturated fatty acids require elevated temperatures for solution.
https://link.springer.com/article/10.1007/BF02645899So you’re limited to Potassium hydroxide (to make Potassium salts), coconut oil, lauric, myristic and oleic acid.
With other oils, you may wait for the insoluble soaps to precipitate down, then draw the upper layer with just the soluble ones
but I don’t know if you’ll need a centrifuge for that. -
How about adding some emulsifier like GMS 1-2% and Cetyl stearyl alcohol 0.5-3%?
Though it might decrease the pearl effect and become cream like. -
Is there an advantage mixing soap and an SLS/SLES/CAPB based recipe?
Sounds to me you need to get rid of the “soap based” idea - your recipe is anyway not 100% soap based so why bother? -
^^^ What David said. Think: Does soap have properties better than the synthetics? It doesn’t clean better, it doesn’t have more foam… but it does come with a high pH that makes preservation more problematic. Most factors sell potassium cocoate, a liquid soap. If you try washing your face with it, soon you’ll wish you hadn’t because your skin will dry out. Is that really something you want in a product? As I said, I have wasted enough time on all this to know that it doesn’t work.

@UsmanAli, not sure why you refer to a “soap base” when in fact there is no soap. We produce a range of liquid soap face washes. These sell well. Yes @Belassi they do have a high pH and this eliminates the need for preservatives. And no, with the correct selection of oils and careful saponification calculations, liquid soap WILL NOT dry out the skin. If they did, I would have been out of business years ago.

Mike, you failed to note what I said: potassium cocoate, a liquid soap. If you try washing your face with it, soon you’ll wish you hadn’t because your skin will dry out.
