- CMIT is a preservative closely related to MIT; it is a strong skin sensitizer, often restricted or banned in baby and leave-on hygiene products.
- How it works: CMIT, like MIT, prevents microbial growth but is a potent contact allergen.
- EU bans CMIT/MIT blends in leave-on products like wipes
- Myth: CMIT and MIT are different risks. They are closely related with similar sensitization profiles
How Methylchloroisothiazolinone (CMIT) Works
CMIT, like MIT, prevents microbial growth but is a potent contact allergen. It is often used in a 3:1 CMIT/MIT blend. Due to allergy concerns, it is strictly limited in rinse-off products and banned in leave-on products (including baby wipes) in many markets. Safe alternatives exist.
Examples and Applications
- EU bans CMIT/MIT blends in leave-on products like wipes
- Rinse-off products allow very low CMIT/MIT limits
Methylchloroisothiazolinone (CMIT) vs. Related Terms
| Term | What it is | Key difference |
|---|---|---|
| MIT | Methylchloroisothiazolinone (CMIT) | MIT and CMIT are chemically related sensitizers, often used together and restricted together |
Limitations and Common Misconceptions
- Myth: CMIT and MIT are different risks. They are closely related with similar sensitization profiles
- Myth: CMIT is needed in baby wipes. Safe preservative alternatives exist
Is CMIT banned in wipes?
In many markets CMIT/MIT are banned in leave-on products like baby wipes; only low limits in rinse-off products.
How do I avoid CMIT in wipes?
Choose wipes labeled MIT/CMIT-free or with a simple preservative system (e.g., phenoxyethanol).
