Health hazards

powder mixture) May cause skin and eye irritation. May cause irritation of the upper ------------------------------------------------------------------------------- respiratory tract (nose, mouth and/or throat), resulting in sneezing coughing and sore throat. Long-term respiratory exposure exceeding exposure limits may damage the lungs, leading to impairment of lung capacity. The acute and chronic health effect statements below are for the pure chemicals only, unless noted.

Potential Acute Health Effects

BISPHENOL A) Irritating to the upper respiratory tract, eyes, and skin. (CARBON BLACK) May be irritating to the eye & cause conjunctivitis. Prolonged or repeated skin contact may cause irritation. (SILICA, AMORPHOUS FUMED) Irritating to eyes, nose and upper respiratory tract. (TITANIUM DIOXIDE) INGESTION: Low oral toxicity. No toxic effects due to ingestion are described in literature. INHALATION: Irritating to upper respiratory tract. EYE CONTACT: Irritating. (ALUMINUM HYDROXIDE) Dust exposure causes eye irritation; basic eye burns are possible depending upon the duration of contact. This material is reported to exhibit a low order of toxicity via inhalation & ingestion. Prolonged skin contact may result in minor mechanical irritation.

Potential chronic health

CARBON BLACK) In 1978, NIOSH concluded that "carbon black may cause adverse pulmonar & heart changes" & "may pose a cancer risk" due to absorbed polycyclic hydro-carbons. Studies have not shown a significantly increased circulatory malignant or respiratory morbidity among carbon black workers in the U.S. Prop 65 "This chemical is known to the state of California to cause cancer" (SILICA, AMORPHOUS FUMED) Currently being reviewed by IARC. No chronic health hazards are known. (TITANIUM DIOXIDE) Laboratory studies show that inhalation exposure to high levels (250 mg/kg) of Titanium Dioxide causes cancerous tumors in rats. This response occurs at lower exposure levels and may be due to the high levels overwhelming normal lung clearance mechanisms. The relevance of this data to humans is not significant where the TLV is observed.
