Old Spice has been around for a long time, and the company continues to make new products for men. It offers an expansive line of deodorants: 14 varieties of deodorants and 36 choices for antiperspirant deodorants. The active and inactive ingredients among the selections vary; however the active ingredients must be approved by the Food and Drug Administration (FDA).

Dipropylene Glycol

Dipropylene glycol is the first ingredient in two out of three types of deodorant from Old Spice. The ingredient is water-soluble and colorless and acts as a solvent in many deodorants and other cosmetic products. Dipropylene glycol helps to carry the fragrance, and is considered to be safe and non-irritating to the skin.

Water

Two out of three Old Spice deodorants contain water as the second ingredient. In the third deodorant it is listed as the third ingredient. Water is used as a solvent to dissolve the other ingredients. Only some of the Old Spice antiperspirants contain water.

Sodium Stearate

Old Spice deodorants, not the antiperspirants, contain sodium stearate. This substance is also used in soaps, hair products, fragrances and makeup. Sodium stearate can provide a product with lubrication and thickness.

Propylene Glycol

Propylene glycol is found in Old Spice deodorants and in some antiperspirants. It can provide moisture and absorb excess water. Although it considered to be safe, this organic alcohol can cause irritation if you have sensitive skin.

Aluminums

In the Old Spice antiperspirant deodorants you will find either Aluminum Zirconium Trichlorohydrex GLY or Aluminum Chlorohydrate as the main ingredient. These chemicals are used to reduce sweat secretion from the underarm area. You will typically find these substance in ranges from 10 percent to 20 percent in most antiperspirants. The Food and Drug Administration approve the use of these compounds in antiperspirants, but now require a warning to be printed for people with kidney disease, because the kidneys help to remove aluminum from the body.

Additional Ingredients

Depending on the form, scent, and type of Old Spice deodorant or antiperspirant you choose, you will find a number of different additional ingredients. Synthetic colors, such as Blue 1 and Green 5, are added to many deodorants. Some of the antiperspirants contain Castor oil or mineral oil. Additionally, alcohol is a common ingredient in some forms of deodorant. One of the final ingredients used is fragrance, to create the specific scent of each deodorant.
