Unacceptable

Unacceptable: EWG VERIFIED products cannot contain this ingredient



This ingredient is a member of a class of compounds called per- and polyfluoralkyl substances, or PFAS. With the many health effects noted for the few well studied PFAS substances, and hundreds of other PFAS in commerce lacking toxicity data, an appropriate degree of precaution is required to protect human health. EWG consumer database now includes a category rating for all PFAS ingredients.

Understanding scores

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

Hazard score

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.

Score legend

Data availability

The Skin Deep data availability rating reflects the number of scientific studies about the product or ingredient in the published scientific literature.
