Deodorant is a personal care product designed to mask or eliminate body odor caused by the bacterial breakdown of sweat. It typically comes in various forms, including sticks, sprays, and roll-ons. Most deodorants contain ingredients that help neutralize odors and may also include fragrances to provide a pleasant scent. Some deodorants are formulated with antiperspirant properties, which reduce sweating by blocking sweat glands. Common ingredients in deodorants include aluminum compounds, baking soda, and essential oils. People often choose deodorants based on their skin type, scent preference, and whether they want a natural or synthetic product.
