Lysol

Lysol (/ˈlaɪsɒl/, LYE-sol; spelled Lizol in India) is an American brand of cleaning and disinfecting products distributed by Reckitt, which markets the similar Dettol or Sagrotan in other markets. The line includes liquid solutions for hard and soft surfaces, air treatment, and hand washing. The active ingredient in many Lysol products is benzalkonium chloride, but the active ingredient in the Lysol "Power and Free" line is hydrogen peroxide. Lysol has been used since its invention in the late 19th century as a household and industrial cleaning agent, and previously as a medical disinfectant.
The first Lysol Brand Antiseptic Disinfectant was introduced in 1889 by Gustav Raupenstrauch to help end a cholera epidemic happening in Germany. The original formulation of Lysol contained cresols. This formulation may still be available commercially in some parts of the world. Formulations containing chlorophenol are still available in the United Kingdom.
In 1911, poisoning by drinking Lysol was the most common means of suicide in Australia and New York. One of the active ingredients, benzalkonium chloride, is highly toxic to fish (LC50 = 280 μg ai/L), very highly toxic to aquatic invertebrates (LC50 = 5.9 μg ai/L), moderately toxic to birds (LD50 = 136 mg/kg-bw), and slightly toxic ("safe") to mammals (LD50 = 430 mg/kg-bw).
In 1918, during the Spanish flu pandemic, Lehn & Fink, Inc. advertised Lysol disinfectant as an effective countermeasure to the influenza virus. Newspaper advertisements provided tips for preventing the spread of the disease, including washing sick-rooms with Lysol, as well as everything that came in contact with patients. A small (US50¢) bottle made 5 US gallons (19 L; 4.2 imp gal) of disinfectant solution, and a smaller (US25¢) bottle made 2 US gallons (7.6 L; 1.7 imp gal). The company also advertised the "unrefined" Lysol F. & F. (Farm & Factory) for use in factories and other large buildings – a 5-US-gallon (19 L; 4.2 imp gal) can, when diluted as directed, made 50 US gallons (190 L; 42 imp gal) of disinfecting solution.
The Lysol disinfectant douche once was "the leading feminine hygiene product" in the United States. Advertisements for Lysol during the 1930s hinted at its use as a contraceptive but never explicitly promoted it to be used as such. Advertisements did note that Lysol was safe to use including on "delicate female tissues". By 1911, 193 Lysol poisonings were recorded along with five deaths from "uterine irrigation".
Lysol ads also included recommendations from female gynecologists that Lysol would resolve women's marital distress through the practice of complete feminine hygiene and resolve fears of pregnancy for married women. Douching with Lysol disinfectant does not prevent pregnancy and can result in undesirable vaginal health outcomes as well as has resulted in death for some women using it as a contraceptive or as an abortifacient.
Earlier formulations of Lysol contained cresol, a compound that can induce abortions, and it was widely used by women who could not otherwise obtain legal abortions in the United States, although the medical community was relatively unaware of the phenomenon for the first half of the 20th century. It remained a popular birth control method from the Great Depression through the 1960s. By the 1960s, published medical literature had acknowledged the common use of Lysol and other soaps to induce abortions, which could lead to fatal renal failure and sepsis.
Ownership: Lehn & Fink was acquired by Sterling Drug in 1967 and Reckitt & Colman acquired L&F in 1994 when Bayer acquired Sterling-Winthrop. As of 2015 Lysol products were distributed by Reckitt Benckiser LLC of Parsippany, New Jersey.
Different Lysol products contain different active ingredients. Examples of active ingredients used in Lysol products:
Lysol contains P-chloro-o-benzylphenol at a 5-6% concentration. It is a chemical that is absorbed in humans through ingestion and the mucous membranes. The Globally Harmonized System of Classification of Labelling of Chemicals (GHS) has released hazard statements on P-chloro-o-benzylphenol that include and are not limited to “skin irritation, allergic skin reaction, causes serious eye damage, harmful if inhaled, suspected of causing cancer, suspected of damaging fertility, and potentially causes damage to organs through prolonged or repeated exposure”.
According to their website, some of Lysol's products "have been tested by an independent third party and approved by the EPA to kill SARS-CoV-2, the cause of COVID-19, on hard, non-porous surfaces".
Though Lysol contains disinfecting properties, risks of misuse during the heightened sanitation practices of the COVID-19 pandemic did exist. Overuse, misuse, and improper mixing of disinfectant ingredients can cause both acute and chronic effects.
During the COVID-19 pandemic, more surfaces were being disinfected, such as "touch-screens, plastics, rubber, adhesives, stainless steel and other metals". Acute health effects include coughing, shortness of breath, burning and watery eyes, runny nose, and acute skin irritation. Long-term exposure of fragrances and sanitizers in Lysol can "trigger asthma and allergies".
Lysol's major competitors include Clorox, Febreze, Tilex, Oust, Mr. Clean and Pine-Sol.
