What Chemicals Are in Personal Care Products?

There are several chemicals frequently found in personal care and cosmetic products. While a lot of chemicals are regulated by the government, only a small percentage of the chemicals are tested for product safety. For that reason, it is good to know what chemicals are actually in your personal care products, and how harmful those chemicals are.
Common Chemicals With Lower Health Risks
There are some common chemicals in personal care products that have less of a harmful impact on your body. These chemicals can often pose a health risk in excessive amounts but are often chemicals you come in contact with every day through your normal routines, even outside of the self-care routine you have3.
Nickel
Nickel is found nearly everywhere in nature and is mostly harmless in small amounts. Significant contact with nickel can pose a health risk, depending on the type of nickel. However, nickel is listed as a possible carcinogen, and some people can have severe allergic reactions to the metal.
Petrolatum
Also known as mineral oil jelly, petrolatum acts as a moisture retainer. It is often used in hair products to help produce a shiny finish. Petrolatum itself is not toxic, but it can contain PAHs, which are found to be carcinogenic. The PAHs, or polycyclic aromatic hydrocarbons, can also cause an allergic reaction or rash.
Fragrance
Fragrance is a significant ingredient in almost all personal care products. Fragrance can be listed just as that and can be produced by any combination of artificial chemicals, natural scents, and essential oils. Even fragrance-free products can contain chemicals to mask the normal scent of the product.
Since there are so many forms of fragrances, it’s hard to determine if there are specific health risk factors to consider. The main issues with fragrances come down to potential allergic reactions and depending on the scent, possible triggering of headaches or asthmatic symptoms. While these side effects can be distressing, they are not considered toxic.
Common Chemicals With Severe Health Risks
While there are several chemicals that go into your personal care products, there are a few that do pose significant health risks. These health risks can range from cancer to kidney failure, and problems with your hormones. Any one of these risks can significantly damage your quality of life, just because you used the wrong personal care products.
Highly toxic chemicals to avoid include
- Mercury, lead, other heavy metals
- Formaldehyde
- Parabens
- Siloxanes
- 1,4-Dioxane
Heavy Metals Like Mercury and Lead
Heavy metals can be found in a few different types of personal care products. Mercury is found in the preservative known as thimerosal. Mercury, like most heavy metals, builds up in your system over time and can cause severe brain damage. Lead can sometimes be found as a contaminant in hydrated silica, and the chemical lead acetate can be found in some hair dyes. Lead, like mercury, is a heavy metal and is also considered neurotoxic.
Formaldehyde
Formaldehyde is a chemical that can have a severe impact on your body, causing things like immune-system toxicity and cancer. It is commonly found in cosmetic adhesives, like nail or eyelash glue, in dyes and nail polish, and sometimes even in hygiene products like baby soap.
Parabens
Parabens (in several forms) can be found in almost every personal care product on the shelf. Parabens are dangerous because they can be absorbed through the skin, disrupt your normal hormone production and even cause your fertility levels to decline. Some parabens have been linked to premature skin aging as well. Other personal health impacts from parabens include cancer and neurotoxicity.
Siloxanes
Siloxanes are commonly used in stick deodorants and moisturizers. These chemicals are used for their drying effect, usually to make lotion or deodorant feel dry to the touch. Siloxanes are one of the many chemicals that can impact the environment, as they can accumulate in aquatic animals like fish. This, along with the hormone disruption and potential fertility impairment, makes siloxanes a significant hazard.
