Parabens are widely used preservatives that prevent the growth of bacteria, mold and yeast in cosmetic products. Sounds good, right? Not so fast, they do more than that. Parabens possess estrogen-mimicking properties that are associated with increased risk of breast cancer. These chemicals are absorbed through the skin and have been identified in biopsy samples from breast tumors. They can be found in makeup, body washes, deodorants, shampoos and facial cleansers. You can also find them in food and pharmaceutical products.
#2 Synthetic Colors
If you take a look at your product label and notice FD&C or D&C, they represent artificial colors. F — representing food and D&C representing drug and cosmetics. These letters precede a color and number (e.g., D&C Red 27 or FD&C blue 1). These synthetic colors are derived from petroleum or coal tar sources. Synthetic colors are suspected to be a human carcinogen, a skin irritant and are linked to ADHD in children. The European Classification and Labeling considers it a human carcinogen and the European Union has banned it.
A group of chemicals used in hundreds of products to increase the flexibility and softness of plastics. The main phthalates in cosmetics and personal care products are dibutyl phthalate in nail polish, diethyl phthalate in perfumes and lotions, and dimethyl phthalate in hairspray. They are known to be endocrine disruptors and have been linked to increased risk of breast cancer, early breast development in girls, and reproductive birth defects in males and females. They can be found in deodorants, perfumes/colognes, hair sprays and moisturizers.
#4 Sodium lauryl sulfate (SLS) / Sodium laureth sulfate (SLES)
This surfactant can be found in more than 90 percent of personal care and cleaning products (think foaming products). SLS’s are known to be skin, lung, and eye irritants. A major concern about SLS is its potential to interact and combine with other chemicals to form nitrosamines, a carcinogen. These combinations can lead to a host of other issues like kidney and respiratory damage. They can be found in shampoo, body wash/cleanser, mascara and acne treatment.
Formaldehyde and formaldehyde-releasing preservatives (FRP’s) preservatives are used in many cosmetic products to help prevent bacteria growth. This chemical was deemed as a human carcinogen by The International Agency for Research on Carcinogens (IARC) and has been linked to occupational related cancers: nasal and nasopharyngeal. It is known to cause allergic skin reactions and it may also be harmful to the immune system. It can be found in nail polish, body washes, conditioners, shampoos, cleansers, eye shadows, nail polish treatments.
A petrochemical derived from petroleum or coal tar sources. You may see it on labels listed as benzene, toluol, phenylmethane, methylbenzene. Tolueneis a potent solvent able to dissolve paint and paint thinner. It can affect your respiratory system, cause nausea and irritate your skin. Expecting mothers should avoid exposure to toluene vapors as it may cause developmental damage in the fetus. Toluene has also been linked to immune system toxicity. It can be found in nail polish, nail treatments and hair color/bleaching products.
#7 Propylene glycol
Propylene glycol is a small organic alcohol commonly used as a skin-conditioning agent. It’s classified as a skin irritant and penetrator. It has been associated with causing dermatitis as well as hives in humans — these sensitization effects can be manifested at propylene glycol concentrations as low as 2 percent. It can be found in moisturizers, sunscreen, makeup products, conditioners, shampoo and hair sprays.
#8 Isopropyl Alcohol
Also used in antifreeze and as a solvent in shellac, this hair product ingredient is no good for hair regrowth.
#9 Mineral Oil
This derived substance is commonly used petroleum ingredient. It coats the skin just like plastic wrap. It stops the skin fro releasing toxins and can slow down normal cell development.
#10 PEG-Polyethylene Glycol
Used in cleansers to dissolve oil and grease as well as thicken products. PEG contribute to stripping the Natural Moisture Factor, leaving the immune system vulnerable.
