Diethylenetriaminepentaacetic acid [67-43-6]

Diethylenetriaminepentaacetic acid  [67-43-6] Diethylenetriaminepentaacetic acid is its main use as an ingredient in wood pulp for bleaching paper. DTPA is designed to capture metals that break down hydrogen peroxide. The DTPA complex is used in the diagnostic study of renal function.

 Hazard pictograms

Labels for hazardous chemicals and mixtures that are part of the Globally Harmonized System of Classification and Labeling of Chemicals (GHS). The pictograms recommended by GHS have the shape of a square set on the top. They should contain a black symbol on a white background with a red border.
Priority rules to be observed in connection with the labeling of a substance:
– the skull and crossbones, the exclamation mark pictogram should not be added.
– corrosivity, the pictogram exclamation mark should not be added if it concerns eye or skin irritation.
– health hazard determining respiratory sensitization, the exclamation mark pictogram should not be added if it concerns skin sensitization or irritation to eyes or skin.
