Menthol Crystals are wonderful for shower steamers or other bath and body products where you want a strong peppermint scent and accompanying sensation. The typical usage is 2.5 to 5% depending on the product you are making. They are soluble in alcohol or oil, but not in water. Please be thoroughly familiar with your formula and application of any product containing menthol crystals before use. The crystals are packaged in 4 oz amounts in zip-top 4 mil stand up pouches that are heat sealed. The scent is generally not noticed when the zip is closed.
Note: It is not for use near the eyes, and not for use by pregnant or nursing women.
