Common Harmful Chemicals in Sunscreen
Chemical Name
Why it’s harmful
Benzophenone
Benzophenone (BZP) is a photoinitiator, fragrance enhancer, and ultraviolet stabilizer, used in a variety of industrial applications. Despite not being registered as a pesticide in the U.S., it's involved in the production of insecticides and agricultural chemicals. Its toxic effects on humans are scarcely documented, but it presents little hormonal activity on cell lines. Animal studies show it possesses no estrogenic activity, but it can transform into derivatives with such activity under UV irradiation. It did not show reproductive toxicity or carcinogenicity in rats and mice, respectively, even at high doses. It can be bioactivated through specific enzymes. For aquatic life, fathead minnow larvae were more sensitive to BZP, ranking it in the middle of the toxicity order of six benzene derivatives.

Butylated Hydroxyanisole
3-tert-Butyl-4-hydroxyanisole is a component of the food preservative Butylated Hydroxyanisole, used where Butylated hydroxytoluene is restricted. It serves as an oxidation inhibitor for human consumption. Despite lacking human studies, animal tests reveal no mutagenic activity. Its mutagenicity was evaluated using Salmonella typhimurium and Chinese hamster fibroblast cell line, with chromosomal aberrations induced only in the presence of the S9 mix.
Butylated Hydroxytoluene
BHT, a toluene-based ingredient, serves as a preservative in food and personal care products. Safety assessments have noted toxic effects in lung tissue when BHT was applied to rats' skin but considered the low concentrations in cosmetics safe. The American Conference of Governmental Industrial Hygienists (ACGIH) suggests moderate evidence of BHT being a respiratory irritant in humans.
DEA Oleth-3 Phosphate
DEA Oleth-3 phosphate is employed in skincare as an emulsifying, cleansing, and dispersing agent that facilitates the cohesive mixing of oil and water ingredients in cosmetic products. It is a combination of ethoxylated fatty acid oleic acid and liquid phosphoric acid. However, ethanolamines like diethanolamine (DEA), found in various consumer products including cosmetics and cleaning products, have been associated with liver tumors. To reduce contamination from carcinogenic nitrosamines, the European Commission prohibits the use of DEA in cosmetics.
DEA-Cetyl Phosphate
DEA-Cetyl Phosphate serves as an emulsifier and surfactant in cosmetics and personal care products. However, it can accumulate in the liver and kidneys, leading to organ toxicity and potential neurotoxic effects like tremors. Maternal exposure to DEA may also have lasting impacts on memory function and brain development in offspring. Furthermore, DEA has been linked to male reproductive health issues, causing abnormalities in sperm structure and function.
Homosalate
Homosalate is a commonly used chemical in sunscreens and SPF-containing skincare products, primarily known for its UV-absorbing properties. However, it is a potential endocrine disruptor, particularly affecting the estrogen, androgen, and progesterone hormone systems. Studies in breast cancer cells indicate increased cell growth and multiplication following homosalate exposure. Moreover, homosalate's presence in human breast milk and its estrogenic activity in placental tissues raise concerns about its impact during vulnerable developmental stages. Additionally, homosalate has been shown to enhance the absorption of pesticides when applied to the skin, emphasizing the need for caution in its use.
Lauramide DEA
Lauramide DEA is an ethanolamide mixture of lauric acid commonly used in soaps, cleansers, and shampoos. It is known to cause mild to moderate eye irritation and mild to severe skin irritation. While the Cosmetic Ingredient Review (CIR) Expert Panel has deemed it safe for use, caution is advised in cosmetics and personal care products that also contain nitrosating agents to prevent the formation of potentially carcinogenic nitrosamines.
Linoleamide MEA
Linoleamide MEA is utilized in cosmetics for functions such as foam boosting, antistatic properties, viscosity control, and hair conditioning. It is used in a wide range of consumer products, including cosmetics, personal care items, and household cleaning products. However, it has the potential to irritate the eyes and skin at higher concentrations and may cause short-term exposure-related effects on the central nervous system, nasal irritation, or pulmonary edema.
Myristamide DEA
Methylparaben is a non-volatile compound used as an antimicrobial preservative in various products, with contact exposure reported to cause dermatitis in some people. The mechanism of this sensitivity is not well understood, but it seems to intensify when applied to broken or damaged skin. Animal studies showed it to be generally non-toxic and non-carcinogenic, with no significant adverse effects noted at high exposure levels. There were contrasting findings on its effect in uterotrophic assays and its toxicity to sperm cells. In ecotoxicity studies, it affected the expression levels of genes in male Medaka fish at certain concentrations
Octinoxate
Octinoxate, commonly found in various cosmetic and personal care products such as hair color products, sunscreen, lipstick, and skin creams, is an endocrine disruptor that mimics estrogen and can affect thyroid function. It has been detected in human urine, blood, and breast milk, indicating systemic exposure. Octinoxate's potential health concerns include its impact on cell proliferation in response to estrogen exposure, disruptions in thyroid hormones, alterations in reproductive systems, and adverse effects on the development of male and female fetuses, as well as their offspring.
Oleamide DEA
Oleamide DEA is utilized in shampoos, hair dyes, bath products, and lotions for enhancing foaming capacity, stabilizing foam, and thickening the water-based components. However, there is a concern that in cosmetics, DEA can react with other ingredients to create a carcinogen called nitrosodiethanolamine (NDEA), which can be absorbed through the skin.
Oxybenzone
2-Hydroxy-4-methoxybenzophenone (Benzophenone-3; BP-3) is a compound used as a UV absorber and stabilizer in plastics, paints, and sunscreens. Human studies have found photosensitivity to it, while non-human animal studies have found that high concentrations contribute to changes in liver weight and disruptions to reproductive parameters in mice and rats. It is identified as an endocrine-disrupting chemical and can affect the behavior of certain fish species. Despite this, it did not induce gene mutations in tests with the bacterium Salmonella typhimurium.
Padimate O
Padimate O is an active sunscreen agent found in cosmetics and over-the-counter sunscreens, regulated by the FDA at concentrations up to 8%. It is a derivative of the PABA sunscreen ingredient and has been associated with concerns such as releasing free radicals, DNA damage, estrogenic activity, and allergic reactions in some individuals. Padimate O is an active sunscreen agent found in cosmetics and over-the-counter sunscreens, regulated by the FDA at concentrations up to 8%. It is a derivative of the PABA sunscreen ingredient and has been associated with concerns such as releasing free radicals, DNA damage, estrogenic activity, and allergic reactions in some individuals.
Phenoxyethanol
2-Phenoxyethanol is a hazardous substance toxic by all routes of exposure, and is used widely in products like cosmetics, soaps, and inks, among others. The effects of exposure to this faintly aromatic, colorless, oily liquid can include eye irritation, headaches, tremors, and CNS depression. It's crucial to rinse exposed eyes with tepid water for at least 15 minutes and to wash exposed skin thoroughly with soap and water in case of contact. The substance requires preheating before ignition can occur, and if involved in a fire, gentle water spray can extinguish the fire by inducing frothing.
Polyacrylamide
Acrylamide is a man-made white crystalline solid primarily used in the production of polymers and copolymers. In humans, it is toxic and irritates the skin and mucous membranes, and can affect the central, peripheral, and autonomic nervous systems leading to symptoms like memory difficulties, confusion, slurred speech, and excessive sweating. It may cause peripheral neuropathy, resulting in loss of sensation and muscle wasting. Recovery after exposure can take months to years. Animal studies indicate acrylamide accumulates in the nervous system, liver, kidney, and male reproductive system, causing degenerative changes. It might disrupt metabolism, induce oxidative stress, cause chromosomal aberrations, and tumor initiation. There is no evidence of teratogenic effects in humans or causing cancer. It has also shown genotoxic effects in some aquatic species like C. Auratus and mussels.
Stearamide MEA
Stearamide Monoethanolamine (MEA) is an ingredient in cosmetics and personal care products like deodorants, shampoos, makeup, and bath items. Its role is to thicken the water-based part of these products and enhance their foaming properties and foam stability. MEA was found to be non-irritating to the skin at a 17% concentration, but it caused slight to moderate irritation to the eyes of rabbits.
Styrene
Styrene is a colorless to yellowish, oily liquid used mainly in plastic, synthetic rubber, and resin production but also as a flavoring agent. Acute human exposure can cause irritation, drowsiness, and vertigo, with skin blistering and dermatitis resulting from long-term contact. It has been linked to increased rates of certain types of cancer, liver effects, and problems with the reproductive system. Animal studies have similarly shown irritation, central nervous system effects, and links to cancers. Styrene's endocrine disruptor activity appears negligible in humans and other vertebrates, but there is evidence of impact in certain aquatic species.
Titanium Dioxide
The study on 1,576 U.S. workers exposed to TiO2 for over a year from 1956 to 1985 showed no increase in lung cancer or chronic respiratory disease, and no cases of pulmonary fibrosis. Cases of pulmonary fibrosis related to TiO2 exposure have been reported, possibly due to silica contamination. There are no listed effects for short-term or long-term exposure. Although NIOSH recognises ultrafine TiO2 as a potential occupational carcinogen, data is insufficient to classify fine TiO2 similarly. Epidemiological studies do not provide clear evidence of lung cancer risks from TiO2 dust exposure.
Triethanolamine Lauryl Sulfate
An eye irritant; May cause corneal damage on prolonged contact; [CAMEO] A skin and eye irritant, based on animal studies; [IUCLID] An irritant; May cause serious eye injury; [MSDSonline] See Triethanolamine.
Diethanolamine
Diethanolamine is a chemical found in various consumer products like shampoos, cosmetics, and pharmaceuticals. Acute exposure in humans can result in irritation of the nose, throat, and skin. However, no detailed data is available on its chronic, reproductive, developmental or carcinogenic effects on humans. Studies on animals reveal that acute oral exposure can influence the liver, blood, kidney, and central nervous system, while dermal exposure has been connected with an increased incidence of liver and kidney tumors in mice. Production of first-degree burns, skin irritation, occupational asthma, kidney, and liver injury risk, and potential skin sensitization are some other adverse effects associated with diethanolamine.

Methylchloroisothiazolinone
5-chloro-2-methyl-4-isothiazolin-3-one (CMI) is a compound frequently used as a preservative in cosmetics, hygiene products, and other industrial applications such as hydraulic fracturing fluids. It can also be deployed as a pesticide in the U.S, pending regulatory approval. CMI, which is often used in combination with 2-methyl-4-isothiazolin-3-one (MI), can cause contact dermatitis in humans. Various animal studies have shown that a high exposure to a CMIT/MIT mixture can cause alterations in rats' liver function. The production and use of CMI in a range of products mean it can be release into the environment, with some susceptibility to degradation through photolysis in sunlight. Its mobility in soil is high but volatilization from soil or water surfaces is not expected to be significant. Occupational and general exposure to CMI can occur especially through inhalation and dermal contact with CMI-containing products.

Methylisothiazolinone
Methylisothiazolinone can reportedly cause allergic contact dermatitis in workers who interact with products containing it. This substance is recognized as a contact allergen for consumers using cosmetics that include it. It can cause skin burns and sensitization, and inhaling it may lead to corrosive injuries in the upper respiratory tract and lungs. Ingesting this substance is harmful, and inhalation is toxic. This preservative is linked to the category of isothiazolinones.

Triethanolamine
Triethanolamine appears to cause occupational asthma and allergic contact dermatitis in machinists and photographers, as well as liver and kidney damage in animals with high-dose feeding. It's noted to be an irritant to the skin, eyes, and respiratory tract, with potential to cause skin sensitization, though the rate of skin sensitization in humans is low. Triethanolamine has low acute toxicity, with median oral LD50 values of 4,190-11,260 mg/kg in rats and 5,300-8,000 mg/kg in guinea pigs, and a median dermal LD50 greater than 2,000 mg/kg in rabbits. Triethanolamine is not carcinogenic, developmental toxicant, or toxic to the reproductive system. However, chronic exposure may lead to liver and kidney damage.
