Titanium Dioxide (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.
Other ConcernsEnhanced skin absorption, Use restrictions (moderate), Non-reproductive organ system toxicity (moderate), Irritation (skin, eyes, or lungs) (low), Occupational hazards (high), and Biochemical or cellular level changes (high)
SYNONYMSMICRONIZED TITANIUM DIOXIDE, MICROTIO2, NANO TIO2, NANO TITANIUM DIOXIDE, TITANIUM DIOXIDE (NANO), and TITANIUM DIOXIDE (SUNSCREEN GRADE)
Unacceptable: EWG VERIFIED products cannot contain this ingredient
Titanium dioxide has a long history of use as a sunscreen agent. Nano TiO2 offers greater sun protection than larger titanium particles. Comparatively little is known regarding potential health effects of nanoparticles. They do not penetrate healthy skin, and thus appear to pose a low health risk in lotions. Inhalation of powders and sprays is a concern.

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.
