This thread sort of continues ones from 2017 discussing baby vomit/cheesy smells in soap using cow's milk and one from 2020 discussing baking soda in soap. But I thought it best to just start a new thread.
I want to use powdered cream in an Oatmeal, Cream & Honey soap but I am concerned about getting that baby vomit/cheesy smell in the soap especially since I want to leave it unscented. It is caused by the higher level of butyric acid in cow's milk than goat's milk. But the benefits of milk sure look lovely.
Then I found that baking soda neutralizes butyric acid and removes the smell - in a Google search that had nothing to do with soap making. Pairing that with these comments from 2020 I am now eager to try mixing baking soda with my cow's milk (actually powdered cream).
Does anyone have an idea as to how much I should add to the formula?
Should I stick with 1TBS PPO?
Should I reconstitute the powder with reserved water (I masterbatch lye) and add the baking soda to that before adding to the oils?
Thanks for any ideas, knowledge, jokes.....

Yes, I've tried it... long time ago... did NOT do it Old School though. I'm smarter than that! LOL I used Water, NaOH, Pomace OO & 1 tablespoon baking soda PPO. As I recall the baking soda bumped the lather and produced a mild soap good for sensitive skin. Nice.
My questions are -You can use baking soda as an additive in soap, but baking soda will not actually saponify with fat unless it gets a LOT of encouragement. Typical hot or cold process methods don't work.
