Zinc Oxide (Sunscreen Grade)
- This ingredient’s score is higher if used in products that are inhalable (e.g., sprays, powders) because of respiratory concerns.
- Products with the EWG VERIFIED mark have met use restrictions and warnings based on EWG review of company data.
IMAGE SOURCE: PubChem
Other ConcernsEnhanced skin absorption, Use restrictions (moderate), Persistence and bioaccumulation (low), Non-reproductive organ system toxicity (low), Ecotoxicology (low), Occupational hazards (moderate), and Biochemical or cellular level changes (high)
Restricted - Unaccpetable
The score of this ingredient can vary from Restricted to Unacceptable based on the method of product consumption. For instance, when used in aerosol-based products, this ingredient may pose a risk to respiratory health, leading to a higher score

Sunscreens with zinc oxide usually contain nanoparticles. Zinc oxide in sunscreen offers UVA protection. Nanoparticle zinc oxide in sunscreen does not penetrate healthy skin, and thus appear to pose a low health risk in lotions. Inhalation of powders and sprays is a concern, however.

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.
