Hazardous Substances Data：

Toxicity：

A finely powdered hydrous magnesium silicate. It is used in a variety of industrial processes and products, including rubber, paints, lubricants, insulating materials, cosmetics, and toiletries, such as baby and dusting powders. Acute inhalation of large quantities of talc, such as infants aspirating a massive amount of powder, has caused death within hours because of drying of the mucous membranes, clogging of the smaller airways, pulmonary edema and pneumonia. Chronic inhalation of talc, such as occurs in talc miners, leads to talcosis (a pneumoconiosis) involving pulmonary fibrosis and pleural sclerosis. Lymph nodes can also be affected. There are suggestions that talc can result in cervical or ovarian cancer although evidence for this is not extensive. Some talc is contaminated with asbestos.
