Using Anti-Sweat™ (Aluminum Chlorohydrate) in Soap

Regarding the use of Anti-Sweat™ (Aluminum Chlorohydrate) in soap, it is technically possible to add this ingredient to a soap formulation. However, as the staff reply indicated, you should not expect to achieve the antiperspirant or deodorant benefits typically associated with Aluminum Chlorohydrate when used in soap.

Anti-Sweat™ (Aluminum Chlorohydrate) works by forming a temporary plug in the sweat ducts to reduce sweating and also has an antibacterial effect to help with odor. These mechanisms are designed for leave-on products like deodorants and antiperspirant sticks or roll-ons, where the ingredient remains on the skin.

In a wash-off product like soap, the Aluminum Chlorohydrate would be rinsed away before it can effectively work as an antiperspirant. Additionally, soap formulations typically have a high pH, which may not be compatible with the optimal working pH range (4-6) for Aluminum Chlorohydrate, potentially affecting its stability and efficacy.

Therefore, while you can include Anti-Sweat™ (Aluminum Chlorohydrate) in your soap formulation, its primary function as an antiperspirant and deodorant will likely not be realized.
