People are often worried about these questions, because they directly concern their health and appearance.

While these chemicals serve their own purpose, they may harm sensitive skin, cause rashes, allergies and severe irritation. This is why some people prefer to use natural, organic deodorants.

What chemicals should you look for? Let’s take a closer look.

List of chemicals found in deodorants

Aluminum Zirconium Tetrachlorohydrex Gly

Ever wondered where do these yellow stains on your clothes come from? No, this is not sweat. This is AZTG, one of the most commonly known aluminum compounds found in deodorants.  This compound is used for sweat absorption and clogs the pores to prevent sweating.

Is aluminum zirconium trichlorohydrex gly bad for your health?

It is definitely bad for your white clothing. The yellow stains are very hard to wash off, so you probably do not want to ruin your outfits. Other side effects of this compound are known for are redness, irritation, rashes, etc. So, even if lots of cosmetic companies rely on this chemical ingredient, you can always find better, less messy alternatives that will still efficinently protect you from perspiration.

Aluminum Chlorohydrate

This compound is also a major part of all antiperspirant deodorants and widely used by many cosmetics-producing brands.

What are the effects of a deodorant with aluminum in it? The purpose of this aluminium compound (AI2CI(OH)5) is to affect the pH balance of the underarm skin and keep  dry during the day, avoiding sweating and body odor.

Can this compound harm you?

Although some myths state that aluminum chlorohydrate in deodorant causes poisoning and even breast. The truth is, that it has to be over 25% aluminum concentration in order for this to happen. Everything less than 25% (and this is the usual concentration of aluminum in deodorant) may cause only itching and rashes, so you have nothing to worry about.


In spite of being used by a wide range of antiperspirants producing companies, these chemical compounds can actually be a lot more harmful than the effects of aluminium in deodorant. According to the study of 2004, parabens were found in nearly 15-20% of breast cancer tissues. Although it does not confirm, whether the parabens featured in deodorants are the same chemicals that cause breast cancer or other forms of cancer, avoiding using deodorants that contain large amount of parabens would be wise.


Phthalates are the chemicals that are used to make a deodorant stick to your skin and last for a longer period of time. They are often added to deodorants due to these properties. However, the overexposure to phthalates can do you more harm than rashes-inducing effects of deodorant with aluminum. Phthalates are considered to be EDC – Endocrine Disturbing Chemicals. Basically, these chemicals can affect your endocrine system if you use them for too long and this can be very bad for your health.

Propylene Glycol

This is a very cheap petroleum chemical, that serves as a pigment solvent and a preservative in deodorant production. This chemical has been officially deemed safe by the US Food and Drug Administration, so it is not health hazard – except for the rare cases, when exposure to an extremely high exposure to propylene glycol led to kidney diseases.


This is an antibacterial chemical that prevents the bacteria growth that happens during sweating. These properties make triclosan an important part component of deodorants and many medical products. However, the use of triclosan must be carefully measured, otherwise, the bacteria may adapt to the effect and actually develop a resistance to triclosan and even other antibacterial products. Therefore, you should not rely on triclosan too much and avoid excessive usage.


This chemical compound is the one that keeps other ingredients together, establishing and strengthening the bond between them.
