Common Harmful Chemicals in Body Oil
Chemical Name
Why it’s harmful
Linalool is a naturally occurring terpene alcohol found in many flowers and spice plants, consisting of two enantiomers. It is widely used in commercial products for its pleasant floral and spicy scent, serving as a key ingredient in soaps, fragrances, food flavors, household products, and insecticides. In plants, linalool functions as a metabolite, volatile oil component, antimicrobial agent, and aroma compound. Acute exposure to linalool can lead to central depressive effects with symptoms such as ataxia, reduced motor activity, and respiratory disturbances. Additionally, inhalation, oral intake, or skin absorption can result in irritation, pain, and allergic reactions.
d-Limonene is a liquid with a lemon-like smell, often used as a solvent to substitute for more volatile and toxic organic solvents. When it comes into contact with air, it can oxidize, and this oxidized form is a known skin sensitizer, capable of irritating skin and eyes. The combination of d-limonene and l-limonene is known as limonene or dipentene. The estimated lethal dose for humans is between 0.5 to 5 g/kg, and studies have shown that it can cause diarrhea and liver effects when ingested in high doses.
Phthalates, linked to endocrine disruption, reproductive toxicity, and cancer, are banned in the European Union but remain prevalent in U.S. cosmetics. They are widely used in personal care products, such as nail polish, fragrances, and eyelash glue and other products. A significant loophole allows phthalates to be added to fragrances without disclosure. Health concerns include endocrine disruption, developmental and reproductive toxicity, and potential carcinogenicity.

Butylparaben, a chemical used in various products, has been shown to cause skin irritation in humans and potential sensitization in dermatitis patients. Animal studies indicate that it has low to moderate oral toxicity and can cause damage to the liver, spleen, and thymus. It can also lead to cell proliferation in rats' stomachs, though it was not found to be carcinogenic or mutagenic. However, it may negatively impact sperm viability and activity, as demonstrated in different in vitro and in vivo studies. Lastly, it proposed weaker aquatic toxicity compared to parabens with longer alkyl chains, but still showed estrogenic effects in certain fish species.
Ethylparaben is a chemical used as a preservative in various products including pharmaceuticals, cosmetics, and adhesives. It exhibits low toxicity in humans and animals, but can cause skin irritation, particularly when applied to damaged skin, and may worsen pre-existing skin conditions. Despite causing cell proliferation in rats' forestomachs and chromosomal aberrations in a hamster ovary cell test, it has shown no evidence of causing cancer. However, it was found to be toxic to fetuses at doses toxic to the mother, though it did not cause malformations (nonteratogenic). Interestingly, while it impacted sperm viability in lab conditions, it showed no negative effects on mouse sperm in actuality.

Methylparaben is an antimicrobial preservative used in food, drugs, and cosmetics. Some individuals can develop contact dermatitis on skin exposure, and allergic reactions have been reported on ingestion, though the evidence is not conclusive. Data from animal studies suggest that methylparaben is practically non-toxic and non-irritating in normal skin conditions, with high thresholds for observed adverse effects. However, it showed chromosome aberrations in a cell assay and variable results in different uterotrophic assays. An ecotoxicity study found changes in the expression of certain genes at specific concentrations in male medaka, a type of fish.
Propylparaben is a stable, non-volatile compound utilized as an antimicrobial preservative in food, drugs, and cosmetics. Human exposure can cause sensitization especially if applied to damaged skin and may cause contact sensitivity with high concentrations. Extensive animal studies reveal that propylparaben is relatively non-toxic, yet it can mildly irritate skin, affect sperm counts in substantial levels, and trigger cell proliferation in the forestomach of rats. However, it is not carcinogenic, mutagenic, or clastogenic, and a significant no-observed-adverse-effect level was reported in rats. Ecotoxicity studies show that it can lead to an increase in plasma vitellogenin levels in rainbow trout and a significant decline of vitellogenin production in zebrafish at varying concentrations.
Isobutylparaben belongs to the paraben family of preservatives used in the food, pharmaceutical, and personal care product industries. Parabens mimic estrogen and have been found in breast cancer tumors in some studies. Parabens are commonly found in various personal care products and foods and have been associated with endocrine disruption, skin cancer risk, developmental and reproductive toxicity, and potential behavioral changes in offspring when exposed during gestation.
Isopropylparaben belongs to the parabens family of preservatives utilized in the food, pharmaceutical, and personal care sectors. Parabens have estrogen-mimicking properties and pose a potential risk as endocrine disruptors. Research has detected parabens in the breast cancer tumors of a significant number of studied women, raising concerns about their safety and hormonal effects.
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.
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.
1,4-Dioxane is a clear, water-soluble liquid that is primarily used as a solvent in chemical manufacturing and laboratory reagents. Other uses leverage its solvent properties, including cosmetics, detergents, and shampoos. However, manufacturers generally reduce 1,4-Dioxane to low levels in these products due to its potential health risks. Acute exposure can result in symptoms such as vertigo, drowsiness, and irritation of the eyes, nose, throat, and skin. Chronic exposure may lead to liver and kidney damage, and the substance is classified as a probable human carcinogen by the EPA. Notably, severe kidney and liver damage, CNS effects, and even death have been recorded after heavy or prolonged exposure.

Oral administration of high doses in adults causes ciricrhosis, hemorrhage, anorexia, jaundice, and dermatitis. The use of this substance is contraindicated in pregnancy at doses larger than the FDA recommend daily allowance. Ingesting 25,000 IU/d over a period of 2-3 weeks may result in toxicity, symptoms of which include liver injury and increased intracranial pressure, leading to blurred vision, headaches, and changes to mental status. The substance is also found to be an irritant and harmful if ingested, with teratogenic effects observed in experimental animals.
Ethylene oxide is a flammable, sweet-smelling gas that easily dissolves in water. This man-made compound is primarily used to create ethylene glycol, which is used to make antifreeze and polyester, and is also used in small quantities for controlling insects in stored agricultural products, sterilizing medical equipment and fumigating spices. Ethylene oxide may cause irritation of the eyes, skin, nose, throat, and lungs, damage to the brain and nervous system, reproductive effects, and is considered by the EPA to be carcinogenic if inhaled. Exposure risks, which are notably prevalent for healthcare workers engaged in sterilization tasks, include CNS depression, eye and mucous membrane irritation and in some cases, cataracts. Despite these hazards, there are conflicted reports regarding ethylene oxide's carcinogenicity in humans.
