Magnesium silicate is the primary component of talc, a common ingredient in cosmetics and personal care products. According to the International Nomenclature of Cosmetic Ingredients, talc is 'powdered native, hydrous magnesium silicate, sometimes containing a small portion of aluminum silicate.' Talc can be contaminated with asbestos fibers, posing risks for respiratory toxicity and cancer. Studies by the National Toxicology Panel demonstrated that cosmetic-grade talc free of asbestos is a form of magnesium silicate that also can be toxic and carcinogenic (NTP 1993).

Understanding scores

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

Hazard score

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.

Data availability

The Skin Deep data availability rating reflects the number of scientific studies about the product or ingredient in the published scientific literature.
