- This ingredient’s score is higher if used in products intended for use on lips due to increased risk of ingestion and absorption.
Other ConcernsEndocrine disruption (moderate), Persistence and bioaccumulation (moderate), Non-reproductive organ system toxicity (moderate), and Ecotoxicology (low)
Unacceptable: EWG VERIFIED products cannot contain this ingredient
BHA (butylated hydroxyanisole) is a preservative and stabilizer; U.S. National Toxicology Program, a part of the National Institutes of Health, has classified BHA as "reasonably anticipated to be a human carcinogen" based on evidence of carcinogenicity in experimental animals.

Cosmetics and personal care products are not required to be tested for safety before being allowed on the market. The Skin Deep® scoring system was designed to help the public understand whether a product is safe to use or whether it contains ingredients of concern.
Every product and ingredient in Skin Deep gets a two-part score – one for hazard and one for data availability. The safest products score well by both measures, with a low hazard rating and a fair or better data availability rating.HOW WE DETERMINE SCORES
The Skin Deep ingredient hazard score, from 1 to 10, reflects known and suspected hazards linked to the ingredients. The EWG VERIFIED® mark means a product meets EWG’s strictest criteria for transparency and health.
The Skin Deep data availability rating reflects the number of scientific studies about the product or ingredient in the published scientific literature.
