BUTOXYETHANOL
WHAT BUTOXYETHANOL IS
Butoxyethanol can be a solvent (helps chemicals dissolve) or a surfactant (create foam/bubbles).
WHERE YOU CAN FIND IT + WHY MADEWITH DOESN’T ALLOW IT
Butoxyethanol is generally found in hair + nail products. It may cause reproductive/developmental toxicity and/or endocrine disruption. It is also a petrochemical, of which are automatically disqualified from MadeWith’s inventory due to their hazardous impact on the environment and human health.
WHERE THEY’RE BANNED OR RESTRICTED
While not banned outright, Butoxyethanol is considered an irritant by the governments of the United States, Canada, and the European Union. The use of this ingredient in personal care products is 10% or less. The Association for Southeast Asian Nations has determined concentration should not exceed 2-4%, depending on the product, and it is not allowed in any aerosol form [2].
