The Blacklist

“Clean” isn’t a regulated term in the fragrance industry, so we’ve decided to define Clean for ourselves.
One part of our efforts includes creating a [Blacklist], an ever-evolving list of ingredients that have been banned from our formulations. 
As a conscious consumer, you deserve to know about these ingredients and their ties to harmful impacts. But jargon means nothing without context, so we’re explaining each [Blacklisted] ingredient below.
