Abstract

In our daily lives, whether it is facial cleanser, shower gel, sunscreen, or hair conditioner, we cannot leave a small guardian that silently guards our skin health - preservatives. Among these preservatives, 2-Methyl-4-isothiazolin-3-one(MIT) has become a concerned role because of its unique bactericidal effect and wide range of applications.

Introduction

2-Methyl-4-isothiazolin-3-one(MIT) is an organic compound with the chemical formula C?H?NOS and a molecular weight of 115.15. This white-to-yellow powdery substance, with a certain smell, has amazing bactericidal power. As an efficient, broad-spectrum fungicide, it can inhibit the growth of bacteria, fungi, mold, and other microorganisms, and protect our skin health.

Uses

2-Methyl-4-isothiazolin-3-one (MIT), finds application in domestic and I & I cleaners, whereas the same product in combination with 5-chloro-2-methyl-4-isothiazolin-3-one (CIT) is an established preservative in personal care and cosmetic products.

1,2-Benzisothiazolin-3-one (BIT) also has biocidal activity but is more commonly used in metal working/cutting oil applications.

Hazards

2-Methyl-4-isothiazolin-3-one (MIT) is allergenic and cytotoxic, and this has led to some concern over its use.A report released by the European Scientific Committee on Cosmetic Products and Non-food Products Intended for Consumers (SCCNFP) in 2003 also concluded that insufficient information was available to allow for an adequate risk assessment analysis of MIT.
