Here's why:
* Soap Making Process: Soap is made through a process called saponification, where fats or oils are reacted with a strong alkali (like lye or sodium hydroxide) to produce soap and glycerin.
* Bicarbonate of Soda: Bicarbonate of soda is a mild base, not strong enough to saponify fats or oils. It's commonly used for baking, cleaning, and neutralizing acids.
However, you can use baking soda as an additive to homemade soap for:
* Mild Abrasiveness: It can add a slight scrubbing power to the soap.
* Deodorizing Properties: It can help absorb odors and freshen the soap.
Important Note: Baking soda is a mild alkali and should be used in very small amounts in soapmaking. Using too much can alter the soap's properties and make it harsh on the skin.
