It dissolves in water and is used in water-based solutions, such as pastes, paints, and oils. (2010). Methylisothiazolinone, MIT, or MI, is the organic compound with the formula S(CH)2C(O)NCH3. 4df). Where is benzisothiazolinone found? (2010). Our Terms of Service apply. Comparisons between the two groups were conducted using nonparametric tests (Mann Whitney U-test), and the ANOVA and Newman-Keuls multiple comparison tests were used to assess differences in the measurements between multiple groups. Autopsies revealed that death was due to reddened lungs and swollen intestines. [11], In the United States, the Environmental Protection Agency has a 1998 data sheet on methylisothiazolinone in their Pesticides section [12] which reads in part "Human Health Assessment: Toxicity: In studies using laboratory animals, methylisothiazolinone has been shown to be of moderate acute toxicity by the oral and inhalation routes. A good guideline to use when shopping for cleaning products, is to make sure the ones that you buy are free from the aforementioned and following ingredients, all of which are known toxins or have known negative impacts on the environment.

It may be present in: Expert. The ratings reflect potential health hazards but do not account for the level of exposure or individual susceptibility, factors that determine actual health risks, Notably also, CMIT is categorized as an extreme skin sensitizer and MIT has been proposed as a major contributor to systemic allergic reactions and skin inflammation27,28,29,30. Background: Preservatives are used widely in cosmetic, household, and industrial products to prevent microbial growth and spoiling of the products. Preventol BM 5.

J Neurosci. Our current study in the mouse has found that the expression of IL-17A and the Th17 cell population in the skin increased following CMIT/MIT epicutaneous exposure combined with OVA. All mice were sacrificed at 24hours after the final OVA sensitization. Sci. However, as MI contact allergy is very common, it is generally relevant. 202, 12131223, https://doi.org/10.1084/jem.20051135 (2005). methyl-benzisothiazolinone ; SCHEMBL1576553 ; Molecular Weight.

Including monoethanolamine (MEA), diethanolamine (DEA) and triethanolamine (TEA). Junttila, I. S. et al. Additionally, our current results indicated that the total serum IgE levels and the number and degranulation extent of mast cells in the skin became significantly increased in normal mice after repeated epicutaneous exposure to CMIT/MIT. Applications Methylisothiazolinone is used for controlling microbial growth in water-containing solutions. A group of atopic dermatitis without IgE elevation or barrier impairment shows a high Th1 frequency: possible immunological state of the intrinsic type. Annu. Immunol. (f) Toluidine blue staining of skin samples. New perspectives on epidermal barrier dysfunction in atopic dermatitis: gene-environment interactions. Novak, N., Bieber, T. & Leung, D. Y. The numbers of mast cells (g) and degranulated mast cells (h) per high-power field were counted. We use cookies to ensure that we give you the best experience on our website. Meets EWG's strictest standards for health and transparency. We observed that CMIT/MIT exposure during OVA sensitization significantly increased the serum total IgE levels compared with mice exposed to OVA alone (Fig. Schwensen, J. F. et al. Our carefully curated plant-based cleaning products proudly carry the EPA Safer Choice label and are USDA Certified Biobased. Devos, F.

Since 2005, it has been widely used in cosmetics and household products, such as moist wipes, shampoos, cleaners and liquid laundry products. The animals were sequentially exposed to epicutaneous CMIT/MIT over 3 weeks (Fig. 112, S128139, https://doi.org/10.1016/j.jaci.2003.09.032 (2003). Benzisothiazolinone, also called BIT, is an off-white to yellowish liquid antimicrobial chemical. Clin. Methylisothiazolinone is commonly used in wastewater treatment processes [4], cosmetics, paints, and detergents [5], and in combination with MCI (in proportions of 3:1) as an active ingredient . It is Mainly non-oxidizing fungicides. [10][11] The American Contact Dermatitis Society named MIT Allergen of the Year for 2013 due to the skin sensitization resulting from dermal exposure to it.[12][13]. However, we used a previously established AD mouse model that presents with the classically characterized features of human AD i.e. 6th ed. In addition, CMIT/MIT exposure induces a systemic allergic reaction and decrease in lung function, resulting in occupational asthma15,16,17. J. Dermatol. Furthermore, the animals exposed to CMIT/MIT with OVA showed increased IL-4 and IL-17A expression in skin, although not IL-13, compared to the mice exposed to OVA alone (Fig. (e) Serum levels of total IgE determined by ELISA. These findings suggested that epicutaneous exposure to CMIT/MIT during allergen sensitization enhances AD-like responses in the mouse. After considering the overall information on its toxicity, uses, and environmental effects, the EPA concluded that it posed no harm to the population. Benzisothiazolinone is a heterocyclic compound. [3] Methylchloroisothiazolinone. Ito, T. et al. It is calculated using a weight-of-evidence approach that factors in all of the hazards or health impacts associated with the ingredients. [13] Cosmetic Ingredient Review Expert Panel (1992). 63, 164167, https://doi.org/10.1111/j.1600-0536.2010.01774.x (2010). Effects of chloromethylisothiazolinone/methylisothiazolinone (CMIT/MIT) on Th2/Th17-related immune modulation in an atopic dermatitis mouse model, https://doi.org/10.1038/s41598-020-60966-8. Book: Fishers Contact Dermatitis. Because the DNA of bacterial cells is naked (prokaryotic), while the DNA of human cells is enveloped, its biological activity is selective. TheEnvironmental Working Group (EWG)reports that Methylisothiazolinone is moderately to highly toxic for freshwater and estuarine organisms. Soo-Jong Hong conceived and designed the experiments, wrote, corrected, and revised the entire manuscript. The LNs were then stained using FITC-labeled anti-IFN-, PERCP-CY5.5-labeled anti-CD4, APC-labeled anti-IL-4, PE-labeled anti-IL-17A and the respective isotype controls (eBioscience) to analyze CD4+ IFN-, IL-4 and IL-17A expression in accordance with the mouse Th1/Th2/Th17 Phenotyping Kit general protocol (BD Biosciences, San Jose, CA).

Debate exists about the concentrations of MIT/CMIT that trigger an allergic reaction, and harmful effects have been found ranging from 7.5 to 100 parts-per-million. Contact Dermat. J. We next investigated whether the epicutaneous exposure to CMIT/MIT during allergen sensitization enhances the systemic immune response in AD mice.
