Common Harmful Chemicals in Floor Cleaner
Chemical Name
Why it’s harmful
Benzene
Benzene is a colorless, sweet-smelling, highly flammable liquid that evaporates quickly into the air and slightly dissolves in water. It's a byproduct of both natural processes and human activities, used extensively in the U.S production of other chemicals for plastics, resins, nylon, rubbers, lubricants, dyes, detergents, drugs, and pesticides. Present in crude oil, gasoline, and cigarette smoke, benzene is also released into the air from burning coal, oil, gasoline stations, and vehicle exhaust. Short-term exposure may cause drowsiness, dizziness, and irritation, while long-term exposure leads to blood disorders, reproductive effects, and even leukemia. Benzene has been classified by EPA as a known human carcinogen, and regulations apply to various industry sectors with potentially high exposure risks.
Sources:
Tripropylene Glycol Monomethyl Ether
Tripropylene Glycol Monomethyl Ether may cause mild and transient eye irritation, and it could have anesthetic effects. Continuous or repeated overexposure may lead to kidney and neural injury. The chemical doesn't show any hematotoxicity, but excessive exposure might result in narcotic or anesthetic effects.
Sources:
Sodium Dichloroisocyanurate
Sodium Dichloroisocyanurate is toxic upon ingestion and act as a strong oxidizer, posing a fire hazard when exposed to organic materials. It may react violently with combustible substances and decompose due to heat or water, releasing toxic gases such as chlorine. It can cause irritation to the skin, eyes and respiratory tract, and prolonged exposure can result in corrosive skin burns. Inhalation of high concentrations can lead to acute pulmonary edema. It may also explode from shock, friction, or other ignition sources, and can cause fires upon contact with combustible materials.
Nonylphenol ethoxylate
Nonylphenol ethoxylate, commonly found in cleaning products, has been linked to allergic contact dermatitis among workers. It is a strong eye irritant, causing mild to severe eye irritation, possible corneal injury, and mild skin irritation. Inhalation can be harmful. It has been shown to cause changes in liver functions and have demonstrated effects on the liver, kidney, and fetus at doses that are toxic to mothers (maternally toxic) in non-mammalian species. Despite these effects, there is no reported teratogenicity, carcinogenicity, or skin sensitization associated with nonylphenol ethoxylate in experimental animals and human studies.
Sources:
Monoethanolamine
2-Aminoethanol is a colorless, viscous liquid that, despite not being registered for pesticide use in the U.S, holds vast potential in a variety of applications. It can be used in cutting fluids, production of soaps, surfactants, salts, corrosion control inhibitors, pharmaceuticals, and even in protective topical solutions against chemical warfare agents. Used as a pharmaceutical adjuvant, 2-Aminoethanol is effective as a solvent for fats and oils and in creating emulsion formulas like lotions and creams. However, it poses health risks, as a 5.9% concentration can irritate human skin and inhalation may cause allergic reactions, liver damage, and liver symptoms.
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.

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.

Perfluorooctanoic Acid (PFOA)
Perfluorooctanoic acid (PFOA) is primarily used to create salts that aid in the processing of producing fluoropolymers and fluoroelastomers. It also acts as a surfactant in firefighting foams, an intermediate in creating fluoroacrylic esters, and a crucial aspect in manufacturing Teflon and similar chemicals. However, exposure to PFOA can lead to adverse health effects, including alterations in thyroid hormone levels, lower fertility, an increased risk of cerebrovascular disease, higher cholesterol and triglyceride levels, a possible link to ADHD, smaller abdominal circumference and birth length in infants, an increased risk of common cold and gastroenteritis in children, and potentially prostate cancer mortality. Studies on animals have indicated possible liver and brain dysfunction, carcinogenicity, and reproductive and developmental toxicity. Ecotoxicity studies found alterations in genes linked to lipid metabolism, hormone action, immune responses, and mitochondrial functions in rare minnows exposed to PFOA.
Perfluorooctane Sulfonic Acid (PFOS)
Perfluoroalkyls are synthetic chemicals known for their ability to resist oil, grease, and water, primarily used in surface protection products and fire-fighting foams. The two most abundant perfluoroalkyls are perflurooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). Studies have observed liver enlargement and elevated cholesterol in animals given high doses, and the presence of PFOS in various populations has raised environmental and health concerns, leading to the phase-out of some PFOS-based chemicals. Tests have shown a range of health effects in animals, including eye irritation, liver changes, teratogenic effects, and more, with no evidence of mutagenicity. However, no substantial link has been found between PFAS concentrations and increased cardiometabolic risk measures in human studies, and there are no known health effects from exposure when used as intended.
Benzisothiazolinone
Isothiazolinones are preservatives known to cause allergic contact dermatitis, primarily in workers involved in manufacturing industries like paint, paper, rubber, and air fresheners. Additionally, there's a reported case of occupational asthma from exposure to this chemical among workers.
Acetone
Acetone is a colorless, flammable liquid that dissolves in water and has a distinct smell and taste. It is also known as dimethyl ketone, 2-propanone, and beta-ketopropane. This manufactured chemical, which is used to create plastic, fibers, drugs, and other chemicals, can also be found in the environment in plants, trees, volcanic gases, forest fires, vehicle exhaust, tobacco smoke, and landfill sites, with industrial processes contributing more to its presence than natural ones. Acetone can be harmful if absorbed through the skin or inhaled, potentially causing irritation to the skin and respiratory tract, as well as adverse effects on the central nervous system (CNS), liver, and kidneys. The allowable exposure limit is set based on its potential to cause eye and upper respiratory irritation and CNS impairment.
Diethylene Glycol Monoethyl Ether
Diethylene Glycol Monoethyl Ether, when administered orally or through the skin in doses exceeding 800-1000 mg/kg/day, can cause central nervous system depression and changes to the liver and kidneys in animals. However, it doesn't exhibit significant developmental toxicity at these levels. The chemical is not expected to have adverse effects unless workers are exposed to its heated liquid mists. It is an eye irritant and provokes harm to the central nervous system, liver, kidneys, red blood cells, and reproductive system in animal feeding studies. Despite these potential harms, it is poorly absorbed through the skin.
DMDM hydantoin
DMDM hydantoin is a substance used in cosmetics that has the potential to cause allergic contact dermatitis, although rinse-off products generally have a low risk. According to various reports, skin sensitization patch testing has yielded positive results.
Laureth-7
Laureth-7, a surfactant derived from lauryl alcohol sourced from coconut or palm oil, is commonly used in personal care and household products, especially laundry detergents. In detergents, it functions by reducing surface tension between water and soil, aiding in the removal of dirt, stains, and oils from fabrics. This ingredient belongs to the Polyethylene Glycols (PEGs) family, which is found in various consumer goods. Despite past contamination concerns, modern manufacturing processes have addressed and eliminated these issues. Although PEGs are not used in certain personal care products, their inclusion in machine detergents is deemed acceptable since they don't directly touch the skin.
d-Limonene
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.
Linalool
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.
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.

Sodium Cumenesulfonate
Sodium Cumenesulfonate is a mild eye irritants that can be significantly absorbed upon ingestion but not after skin application. It has not shown skin sensitization in animal tests but have caused acute toxicity symptoms such as decreased activity, prostration, increased saliva production, diarrhea, and liver congestion. Furthermore, sodium cumenesulfonate has not demonstrated carcinogenic effects in dermal exposure studies.
Trideceth-3
Trideceth-3 is a polyethylene glycol ether of Tridecyl Alcohol used in formulations for its emulsifying and surfactant properties. However, data from the European Union Ecolabel program indicates that this substance possesses high chronic toxicity and very high acute toxicity to aquatic life. Despite these environmental concerns, the Cosmetic Ingredient Review panel has determined Trideceth-3 to be safe when formulated to be non-irritating.
Trideceth-4
Trideceth-4 is a water-soluble compound with notable wetting, permeability, and emulsifying properties. It enhances the effectiveness of certain silicone oils and is used in various applications including metal processing aids, detergents, and household cleaning agents. However, it can be harmful if ingested and is known to cause serious eye damage, skin irritation, and eye irritation, as indicated by the European Chemicals Agency (ECHA). Despite these concerns, the Cosmetic Ingredient Review panel has determined it to be safe when formulated to be non-irritating.
