Application
- Insights into the mechanisms of within-species variation in sensitivity to chemicals: A case study using daphnids exposed to CMIT/MIT biocide.: This study investigates the differential sensitivity of daphnids to 2-Methyl-4-isothiazolin-3-one, highlighting the biochemical mechanisms underlying these variations. The findings provide crucial insights for environmental safety assessments (Kim et al., 2023).
- Effects of the biocide methylisothiazolinone on Xenopus laevis wound healing and tail regeneration.: The study assesses the impact of 2-Methyl-4-isothiazolin-3-one on regenerative processes in amphibians, contributing to the understanding of its biological effects and potential toxicity (Delos Santos et al., 2016).
- T cell lymphomatoid contact dermatitis: a challenging case and review of the literature.: This review includes discussions on 2-Methyl-4-isothiazolin-3-one-induced contact dermatitis, providing valuable information for dermatological applications and safety assessments (Knackstedt and Zug, 2015).

The preservative methylchloroisothiazolinone (MCI)/methylisothiazo- linone (MI) is an important allergen, and has thus been subject to regulation in some areas of exposure, mainly in cosmetics. To examine whether a decline in sensitization prevalence and intensity of elicitation (by the patch

In the EU, Methylisothiazolinone (MI) was approved as a preservative in cosmetics and household products in 2005. Since then, several cases of MI contact allergy have been reported. We studied the prevalence of MI sensitization in patients allergic to Methylchloroisothiazolinone/Methylisothiazolinone

The frequency of sensitization to methylchloroisothiazolinone (MCI)/ methylisothiazolinone (MI) observed in the Information Network of Departments of Dermatology (IVDK) was constantly around 2.1% from 1998 to 2009. After that, it increased to 3.9% in 2011, paralleled by an increase in
