Silica is the most common constituent of sand. Fine silica, typically used in industrial applications and inhaled by workers, is associated with a wide range of disorders, particularly affecting the lungs and respiratory system. In cosmetics for skin use, regular sand presents little, if any risk to people. In contrast, for products that might be inhaled (such as a facial powder), silica particles are finely ground down and may be associated with respiratory toxicity.

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.
