Product name: 2-Methyl-4-isothiazolin-3-one
CAS No: 2682-20-4
2-Methyl-4-isothiazolin-3-one, commonly known as MIT, is a synthetic antimicrobial preservative used in a variety of personal care, cosmetic, and household products. It is a member of the isothiazolinone family and functions as a highly effective bactericide and fungicide. MIT is used primarily to prevent microbial contamination in water-based products such as shampoos, conditioners, lotions, and cleansers. It helps extend the shelf life of products by inhibiting the growth of bacteria, yeast, and molds. Despite its effectiveness, its use has been restricted in many regions due to concerns over skin irritation and allergic reactions.
Application and Effect
2-Methyl-4-isothiazolin-3-one is widely used as a preservative in personal care and cosmetic formulations due to its potent antimicrobial properties. It is particularly effective in inhibiting the growth of bacteria and fungi in water-based products. As a preservative, MIT helps ensure that products like shampoos, conditioners, body lotions, and facial creams remain free from microbial contamination, thus extending their shelf life and ensuring they remain safe and effective for use. One of the main benefits of MIT is its ability to prevent the growth of harmful microorganisms that could cause spoilage, ensuring the integrity and safety of formulations. It is often used in combination with other preservatives to enhance overall antimicrobial efficacy and to provide broad-spectrum protection against bacteria, fungi, and mold. However, despite its efficacy, MIT has been associated with skin irritation and allergic reactions, especially when used at higher concentrations or in leave-on products. Over the years, concerns have been raised about its potential to cause contact dermatitis, particularly in individuals with sensitive skin. As a result, the use of MIT has been restricted in certain regions, such as the European Union, where regulations now limit its concentration in cosmetic products, and it is often excluded from "hypoallergenic" or "sensitive skin" formulations. In response to these concerns, many manufacturers have reduced or eliminated the use of 2-Methyl-4-isothiazolin-3-one in favor of safer alternatives such as phenoxyethanol, ethylhexylglycerin, or natural preservatives. Nevertheless, MIT remains a popular preservative in many rinse-off products like shampoos, body washes, and facial cleansers, where it poses less risk of prolonged skin exposure.
