This is a small simple recipe, I’ve played around with several different formulations but I keep making this one. I like to make 2 small bars out of it. For shampoo bars I like to make small 1.5-2.5 oz sizes. They last incredibly long time. A hard oil like Kokum butter really helps with the hardness of the bar.

Ingredients
Melt
6 g stearic acid
5 g cetyl alcohol
10 g BTMS-50
5 g Kokum butter
Add Hot
15 g CAPB
32 g SCI Powder
22 g SLSa
1 g Panthenol-DL
Cool down (below 120 degrees)
2 g honeyquat
1 g oat extract
1 g rosemary tree essential oil
.5 ml liquid Germall Plus
Instruction
This recipe is in three phases, add the things from the melt into a double boiler, once they are melted together remove from heat and add the things in the add hot category, mix carefully at first, you do not want to get a bunch of surfacant powder in the air. You should have a mask for this part, you do not want this stuff in your lungs. It will all melt in together as you stir. Once it is all combined check the temperature and let it sit for a few minutes until it is cool enough to continue, It’s a good time to add a colorant if you plan on doing that. Once the temperature drops below 120 add the final ingredients and mix until thoroughly combined. press into a mold, or use a press to mold. I use a moon cake press.

Hi, could I replace virgin coconut oil instead the kokum butter as don’t have available in my country. Thanks
If you do you will likely have a very soft syndet bar. I would use the hardest butter you can get access to, if cocoa butter, mango butter or shea are available they would be a better alternatives. The biggest struggle people have with shampoo bars seems to be getting them to solidify enough that they dont turn to mush. Some formulations include adding sodium lactate at arround 1% or less to help harden the bar further. It takes some trial and error, Good luck!
