| Ingredients to avoid |
Common label terms |
Found in these product types |
Purpose of ingredient |
Main concerns |
| Coal tar colors |
FD&C Blue 1, Green 3, Yellow 5 & 6; D&C Red 33 |
Hair color and makeup |
Coloring agents or coloring additives |
FD&C Blue 1 and Green 3 are known carcinogens; D&C Red 33, FD&C Yellow 5 and FD&C Yellow 6 may contain carcinogenic impurities. |
| Diethanolamine |
DEA (TEA and MEA are related ingredients) |
Mascara, sunscreen/tanning oil, body wash/cleanser, foundation, after shave |
Emulsifier or foaming agent |
Acute (short-term) inhalation exposure to DEA may result in irritation of the nose and throat, and dermal exposure may irritate the skin.
The National Toxicology Program (NTP) reported an increased incidence of liver and kidney tumors in mice from dermal exposure to DEA. However, DEA has not been classified as a carcinogen by the Environmental Protection Agency (EPA) or the International Agency for Research on Cancer (IARC).
While DEA is rarely used in cosmetics, related ingredients, such as cocamide DEA, MEA, and TEA, may be contaminated with DEA. |
| 1,4-Dioxane |
Not identified on cosmetic labels because it’s a contaminant, but may be present in cosmetics that contain the following ingredients:
• PEG
• polyethylene
• polyethylene glycol
• polyoxyethylene
• polyethoxyethylene
• polyoxynolethylene
|
A trace contaminant of some chemicals used in cosmetics, detergents, and shampoos |
It is used as a solvent in the manufacture of other chemicals
|
Acute (short-term) exposure may cause eye and nose irritation; exposure to very high levels may cause severe kidney and liver effects and possibly death.
1,4-dioxane is also considered a probable human carcinogen by the Environmental Protection Agency (EPA) |
| Formaldehyde |
Formaldehyde and formalin
Formaldehyde-releasing preservatives include:
• quaternium-15
• 2-bromo-2nitropropane-1,3-diol
• imidazolidinyl urea
• diazolidinyl urea |
Nail treatments, blush and face powder |
Preservative |
Known carcinogen and sensitizer (a chemical that causes a substantial proportion of exposed people to develop an allergic reaction in normal tissue after repeated exposure to the chemical). |
| Fragrances |
Fragrance, parfum |
A variety of products including cleaners, moisturizers and make-up |
Scent, or masking scent |
Fragrances cause more allergic contact dermatitis than any other ingredient; may also cause watery eyes and respiratory tract irritation. |
| Metals, especially lead and mercury |
Lead: lead acetate
Mercury: thimerosal, mercurius solubilis, mercurius sublimates, mercurius corrosives, mercuric chloride |
Lead acetate: hair color
Mercury: pain/wound treatment, artificial tears |
Lead: coloring
Mercury: preservatives, and bleaching |
Lead and mercury are neurotoxins, affecting the brain and nervous system; mercury compounds are banned in cosmetics by the FDA. |
| Nonoxynol or nonylphenol ethoxylate |
Nonoxynol or nonylphenol ethoxylate |
Hair dyes and hair care products |
Surfactant (a substance that reduces the surface tension of liquids, making it easier for them to disperse) |
These chemicals can break down into toxic substances that can act as hormone disrupters, potentially threatening reproductive capacity. |
| Parabens |
Methyl-, ethyl-, propyl- and butyl-parabens |
Facial cleanser, liquid hand soap, conditioner, toothpaste, shaving cream |
Preservative |
Can affect the endocrine system (the glands that produce hormones). |
| Phenylenediamine |
Phenylenediamine |
Hair dyes |
Dark coloring |
Possible carcinogen. |
| Phthalates |
DEHP, DHP, and DBP5 (not identified on cosmetic labels when they are in fragrance) |
Perfume, nail polish, hair sprays, soaps, shampoos |
Plasticizers (substances that make materials more flexible) |
May cause reproductive or developmental effects. |
| Triclosan |
Triclosan |
Lipstick, lipgoss, antiperspirant/deodorant, facial cleanser, liquid hand soap, acne treatment, facial moisturizer/treatment. |
Antibacterial |
May cause skin and eye irritation. May also promote antibiotic resistance. One study suggested that triclosan could form dioxin, a carcinogen, in the presence of sunlight, and another, that it could form chloroform, a probable human carcinogen, in the presence of chlorinated water. |
