they don't kill bacteria, they create an envionment that won't allow them to grow.
Deodorant natural
Before the advent of deodorants, people in Asia rubbed their armpits with ground crystals of alum. Russians used apple vinegar or limejuice. Baking soda is a natural deodorant that neutralizes the odor of sweat. You can create a natural deodorant with baking soda and cornstarch. You can add a few drops of your favorite essential oils such as lavender.
Natural liquid deodorants can be made at home by mixing witch hazel extract, aloe vera gel, mineral water, glycerin and antibacterial essential oils. Alum has been used for personal hygiene for centuries. Crystal mineral stones are used as natural deodorants since they create an environment that makes it impossible for bacteria to thrive. They eliminate the odor-causing bacteria and therefore eliminate body odor.
Many natural deodorants are made with alum. Natural deodorants come in various fragrances - apricot, lavender, clove, lemongrass, chamomile and rose. Natural deodorant body powders deliver soothing dryness and protection. They are created with rice and corn starches and lavender extracts. Natural liquid deodorants contain the goodness of shea butter, apricot oil and corn starch.
Tea tree oil and aloe vera gel are regularly used in natural deodorant products. The fragrance of wild roses or lemon keeps you smelling good. Try out sage-scented natural deodorants that lend a natural and unique scent. Choose natural deodorants made with rosemary or grapefruit extracts. Herbal extracts are usually non-irritating and mild on the skin. The anti-microbial properties of herbal and natural ingredients go a long way in neutralizing odor-causing bacteria. Natural deodorants are environmentally safe and usually hypoallergenic.

Crystal deodorant: Alum was used in the past as a natural underarm deodorant in Europe, Mexico, Thailand, the Far East and in the Philippines where it is called Tawas. It is now commercially sold for this purpose in many countries, often in a plastic case that protects the crystal and makes it resemble other non-liquid deodorants. Typically potassium alum is used.
Antibacterial agent: Alum works as a deodorant because Alum inhibits bacteria growth. This fits the definition of an antibacterial agent. Styptic pencils or Alum powder/crystals can be applied to cuts that have a mild infection.
Ammonium alum
Ammonia alum, NH4Al(SO4)2·12H2O, a white crystalline double sulfate of aluminium, is used in water purification, in vegetable glues, in porcelain cements, in natural deodorants (though potassium alum is more commonly used), in tanning, dyeing and in fireproofing textiles.
Potassium alum
Potassium alumi, K2SO4·Al2(SO4)3·24H2O, this type of alum is very soluble in water. Most commonly, alum crystallizes in regular octahedra form. The solution reddens litmus and is an astringent. When heated to nearly a red heat it gives a porous, friable mass which is known as "burnt alum." It fuses at 92 °C in its own water of crystallization. "Neutral alum" is obtained by the addition of as much sodium carbonate to a solution of alum as will begin to cause the separation of alumina; it is much used in mordanting. Alum is used as a mordant, in the preparation of lakes for sizing hand-made paper and in the clarifying of turbid liquids. It has cosmetic uses as a deodorant and as an aftershave. See the mineral alunite.
