The advantages of adding methyl chloroisothiazolinone to shampoo
The advantages of adding methyl chloroisothiazolinone (CMIT) to shampoo mainly lie in its preservative and antibacterial properties, but it needs to be carefully evaluated in combination with its potential risks. The following is the specific analysis:
Anti-corrosion effect
Methylchloroisothiazolinone is an efficient preservative that can effectively inhibit the growth of microorganisms in shampoo and extend the shelf life of the product. Shampoo is prone to contamination by bacteria, fungi and other microorganisms during use. Adding methyl chloroisothiazolinone can prevent the product from deteriorating and ensure its quality and safety
Antibacterial effect
Methylchloroisothiazolinone has a strong inhibitory effect on microorganisms such as bacteria, fungi and molds. Adding this ingredient to shampoo can help inhibit the growth of microorganisms on the scalp, prevent scalp infections and other problems, and keep the scalp clean and healthy.
Cost-benefit
Methyl chloroisothiazolinone, as a relatively inexpensive preservative, can reduce production costs and enhance the market competitiveness of the product when applied in shampoo.
However, the use of methyl chloroisothiazolinone also has certain risks and limitations:
Irritation: Methylchloroisothiazolinone has a certain degree of irritation to the skin. Long-term use or high concentration contact may cause skin irritation, redness, itching and other symptoms. For people with allergic constitutions, it may become a trigger for scalp allergies.
Content limit: According to relevant regulations, the maximum allowable concentration of methylchloroisothiazolinone and the mixture of methylchloroisothiazolinone with magnesium chloride and magnesium nitrate (methylchloroisothiazolinone: methylisothiazolinone is 3:1) in shampoo is 0.0015%, and it can only be used in rinsed products. The maximum allowable concentration of methyl isothiazolinone alone in shampoo is 0.01%, and the mixture of methyl chloroisothiazolinone and methyl isothiazolinone cannot be used simultaneously with methyl isothiazolinone alone.
