Potash Alum demonstrated effective antibacterial activity against common odor-causing bacteria found on the skin. Laboratory testing showed that a 2% Alum solution inhibited the growth of multiple bacterial strains, helping reduce body odor while maintaining the skin's natural protective flora. The antibacterial effect increased with higher concentrations, confirming Alum's effectiveness as a natural deodorizing ingredient.

Researchers formulated Potash Alum into lotion, gel, and cream using a 2% concentration. Each formulation underwent stability testing under different temperature and humidity conditions. Results showed excellent stability, consistent pH, uniform drug content, smooth texture, and reliable performance throughout the testing period, demonstrating suitability for topical skincare applications.

The study concluded that Potash Alum is a natural ingredient with antibacterial and astringent properties suitable for topical use. Lotion, gel, and cream formulations maintained product quality, stability, and effectiveness throughout testing, supporting Potash Alum as a reliable ingredient for personal care products such as deodorants and aftershave applications.
