This type of shave cream is basically similar to the traditional cold cream.
What is your formula?
-
I apologise, please ignore my previous post here.
I should have said similar to traditional vanishing cream.
The final appearance and texture does not develop immediately - it may take several weeks for that to occur.What is the formula you are using?

That formulation approximates quite well with the formulae I am familiar with. You might wish to increase the potassium hydroxide slightly but, if you’re happy with the product you have made, good!

Dear Mr John, thank you again and thanks for giving a little of your time
You can, please help me just a little more?The cream that bought the Proraso (PRE SHAVE CREAM) has a Pearlescent appearance,but the formula has nothing showing. Why does he keep looking like this? What percentage of soda I can use in this type of cream?
Best Regards, Nilda Potter. -
The pearlescence and correct texture appear only after several weeks of storage. When I was involved in the commercial production of this product type it would take a month to six weeks post manufacture before it was released for sale.
Regarding the inclusion of soda (NaOH). This material stiffens the product so something to be sold in a jar may require NaOH whereas tube products do not.
-
You will get pearliness on second day or instant if you use 2 to 3% of acrylate copolymer but for light weight cream, need to reduce % of glycerin. To reduce soapy effect due to sodium stearate, dimethicone can be added, if required.
-
Mr John, i will make again with 0,5% Potassium hydroxide and 15% stearic acid
por jars cream. Do you think 0,5% is is much Potassium by your great experience? ? Best Regards NP -
I doubt that reducing the potassium hydroxide will achieve anything positive. The secret is to be patient and allow time for the crystallisation of the stearic acid to take place.
One thing to make sure of is to have a high quality stearic acid if there is much unsaturated acid(s) - oleic acid for instance - the pearling effect will be inhibited or prevented completely.
-
Some of the “Stearic Acid” sold commercially has significant amounts of palmitic acid, as well. If you can, try for 95% or greater C18.

Dear Bob, thanks for help me too. Please, I know these:
Stearic Acid vegetable, Double and triple pressure. Can you suggest any known brand that sells the good stearic acid Basf, Lubrizol, ….?
Thanks for caring about my question! .I’ll aproveitr your time a little to ask a question.You know inform where I find formula of shaving soap ( comercial type) bar with ingredients:
Sodium Tallowate, Potassium Stearate, Sodium Cocoate, Sodium Stearate, Aqua, Potassium Cocoate, Glycerin, Parfum, Alpha-Isomethyl Ionone, Hexyl Cinnamal, Limonene, Linalool, Hydroxycitronellal, Lanolin, Titanium Dioxide, Sodium Chloride, Sodium Gluconate, Sodium Silicate, Tetrasodium EDTA, Magnesium Sulphate, Tetrasodium Etidronate -
It is not feasible to manufacture hard shaving soap yourself. It requires specialist equipment both to make the soap and to form it into bars/sticks for consumer use.
A specialist soap finisher should be able perform these things for you.
Regarding stearic acid for shaving cream, the grade termed triple pressed is suitable.
-
Dear Bob, I sought and found Stearic Acid C18 98/100 - vegetable (Palm Oil).
do you think I produce with this acid will have final product better?
best Regads, NP -
Dear John, in my country no one specialist shaving soap fabric. I contact any, but not.
i have SOAP bar extruder, I buy noodle for toilet SOAP, but no industry produces the noodle to shaving soap, where it is easily foundlike France, England, Germany and others. Thanks for replying! -
Dear Perry, I’m not discouraged. On the contrary, the difficulty is what motivates. Because I know that in some
place or someone will give me a solution. Just look. -
I don’t know your whereabouts but, I am still doubtful that it is practical to make this yourself.
