Restricted: EWG VERIFIED products cannot contain this ingredient without adequate substantiation
Quartz is a mineral and the most common form of silicon dioxide or crystalline silica. Respiratory exposure to large quantities of crystalline silica in the work-place setting has been associated with pulmonary silicosis, a severe lung disease. Long-term, high-volume occupational exposure has been also linked to other disorders such as progressive systemic sclerosis, systemic lupus erythematosus, rheumatoid arthritis, dermatomyositis, glomerulonephritis (renal disease) and vasculitis. Research is ongoing on the relevance of these systemic effects to silica exposure in non-occupational settings via consumer products (Steenland 2005; Stratta 2001).

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.
