Methylchloroisothiazolinone and Methylisothiazolinone: The Toxic Preservatives in Your Personal Care

Methylchloroisothiazolinone and Methylisothiazolinone (MCIT/MIT) are preservatives commonly used in personal care products such as shampoos, conditioners, and body washes. While they are effective at preventing the growth of bacteria and fungi in these products, they can have serious health implications for humans.

The Dangers of MCIT/MIT

Research has linked MCIT/MIT to a range of health problems. These preservatives are known skin sensitizers, which means they can cause allergic reactions and skin irritation in some people. In fact, the European Scientific Committee on Consumer Safety (SCCS) has recommended that the concentration of MCIT/MIT in personal care products be limited to 0.0015% due to the high risk of skin sensitization.

MCIT/MIT can also be harmful when inhaled. One study found that exposure to MCIT/MIT in the workplace led to respiratory problems in workers. The study also suggested that the preservatives could be a cause of occupational asthma.

Additionally, MCIT/MIT have been found to be toxic to aquatic life. When these preservatives are washed down the drain and enter the environment, they can have a negative impact on the ecosystem.

Sources of MCIT/MIT

MCIT/MIT are commonly used in personal care products as a preservative. They are often found in shampoos, conditioners, body washes, and other products that contain water. Some manufacturers use these preservatives as an alternative to parabens, which have been linked to their own health concerns.

How to Avoid MCIT/MIT

To avoid the dangers of MCIT/MIT, it is important to read labels carefully and choose products that do not contain these preservatives. Look for products that are labeled as "preservative-free" or "no MCIT/MIT." You can also use resources like the Environmental Working Group's Skin Deep database to search for products that do not contain MCIT/MIT or other harmful chemicals.

In conclusion, MCIT/MIT are toxic preservatives commonly used in personal care products. They can cause allergic reactions, skin irritation, respiratory problems, and harm to aquatic life. To avoid the dangers of MCIT/MIT, it is important to choose products that do not contain these preservatives and to read labels carefully.
