Descripción general

2-Methyl-4-isothiazolin-3-one is a potent biocide useful for controlling microbial growth.
A potent biocide useful for controlling microbial growth

Methylothiazolinone is a bacterial and fungal inhibitor and preservative, as well as a sensitizer. Methylisothiazolinone can activate matrix metalloproteinases (MMPs) in human bronchial epithelial cells to induce apoptosis and inflammatory response. Methylisothiazolinone can promote the development of atopic dermatitis in mice by disrupting Th2/Th17 related immune responses. Methylisothiazolinone can cause mitochondrial damage in the endothelium of rat cerebral blood vessels.
