Ingredients for Glycerin Soap Base to Reduce Sweat and Body Odor

To add properties that help reduce sweat and body odor to a glycerin soap base, you can consider using the following ingredients, keeping in mind that glycerin soap is water-based, so water-soluble ingredients are generally easier to incorporate.

• Anti-Sweat™ (Aluminum Chlorohydrate): This is a primary antiperspirant ingredient that works by reducing sweat production. It also has a deodorant effect due to its antibacterial properties. It is a powder that dissolves upon contact with sweat. It can be used in water-based formulas, but it's often used in low-water or anhydrous systems for a dry feel. Usage rate is typically 5-25% (up to 25% as per FDA). While it can be incorporated, its primary function as an antiperspirant is most effective when left on the skin, which is less the case with a wash-off product like soap.

• DeoMax™ Powder: This is a natural deodorizer derived from Japanese persimmons (Tannin). It is effective at absorbing various types of body odor. It is a water-soluble powder. The usage rate is low, typically 0.1-0.5%. Note that it is a dark-colored powder, which might affect the appearance of clear glycerin soap.

• CycloSorb™ Clear: This is a blend of cyclodextrins designed to absorb odors, particularly those found in sweat. It is a water-soluble powder. The recommended usage rate is 2.5-5.0%. It works by trapping odor molecules. Avoid using fragrances in the same formula as it may absorb them.

• Odor-Kill DO™: This is a liquid ingredient that is effective against odor-causing bacteria. By reducing the bacteria population on the skin, it helps to prevent body odor. It is water-soluble. The usage rate is typically 0.1-1.0%.

For a glycerin soap base, DeoMax™ Powder, CycloSorb™ Clear, and Odor-Kill DO™ are good options specifically for targeting odor through absorption or antibacterial action, and they are water-soluble. Anti-Sweat™ is effective for sweat reduction but might be less impactful in a wash-off product compared to a leave-on deodorant.

It is recommended to test the incorporation and effectiveness of these ingredients in your specific glycerin soap base formulation.
