That is what phenoxyethanol is known for today, according toWebMD.

As a preservative, phenoxyethanol keeps bacteria from making a home in your bottles of foundation or moisturizer tubes.

Thus, your products have a longer shelf life.

However, some may find phenoxyethanol as an irritant, meaning you could be allergic.

In that case, talk to a physician about the options best for you and your skin.

Additionally, babies should not be exposed to high amounts of phenoxyethanol.

The ingredient chlorphenesin also contributed to side effects, according to the report.
