Note to manufacturers: We have assumed a typical particle size for the mineral(s) in your product based on typical industry use. We welcome specific data from manufacturers if actual particle size is different.
Given the incomplete information made available by companies and the government, EWG provides additional information on personal care product ingredients from the published scientific literature. The chart below indicates that research studies have found that exposure to one or more ingredients in this product -- not the product itself -- caused the indicated health effect(s) in the studies reviewed by Skin Deep researchers. Actual health risks, if any, will vary based on the level of exposure to the ingredient and individual susceptibility -- information not available in Skin Deep.
Ingredients in this product are linked to: | |
 | Cancer |
| Developmental/reproductive toxicity |
| Violations, restrictions & warnings |
| Allergies/immunotoxicity |
| Other concerns for ingredients used in this product: Endocrine disruption, Persistence and bioaccumulation, Organ system toxicity (non-reproductive), Irritation (skin, eyes, or lungs), Enhanced skin absorption, Contamination concerns, Occupational hazards, Biochemical or cellular level changes |
Note from EWG: Unlike many other kinds of personal care products, sunscreen can provide health benefits, protecting against the sun's cancer-causing UV radiation. More than one million cases of skin cancer are diagnosed in the U.S. every year. Health officials recommend wearing sunscreen as one of many important steps to minimize skin cancer risk.
