Answer 1

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.

Answer 2

As of May 17, 2026, additional options and refinements are available for glycerin soap formulations targeting odor and sweat:

DeoMax™ Liquid: For clear glycerin soap bases, this liquid version is now recommended over the powder form. It is colorless and maintains the transparency of the soap while providing the same effective deodorizing benefits from Japanese persimmon tannins.
DeoEco™: A new natural, water-soluble odor neutralizer. Unlike simple masking agents, it chemically neutralizes a broad spectrum of malodors, including acidic sweat and sulfur notes.
LipidSoft™ Deo: This naturally-derived ingredient can be incorporated at 1-5% to inhibit the bacterial enzymes that cause body odor, offering a mild alternative for sensitive skin.
Technical Note on Anti-Sweat™: When using Aluminum Chlorohydrate, be aware that it is a high-electrolyte ingredient. In some glycerin soap bases, high electrolyte loads can affect the hardness or clarity of the final product. Small-scale stability testing is highly recommended.
