Additional information

Based on the test results, Acid Orange 7 can be considered to have the following results:

No Adverse Effect level for acute toxicity oral, LD50 > 5000 mg/kg

No Adverse Effect level for dermal toxicity but the value of LD50 > 2000 mg/kg.

Justification for classification or non-classification

Substances can be allocated to one of four toxicity categories based on acute toxicity by the oral, dermal or inhalation route according to the numeric criteria shown in Table 3.1.1 of CLP Regulation (EC n. 1272/2008).

Acute toxicity values are expressed as (approximate) LD50 (oral, dermal) or LC50 (inhalation) values or as acute toxicity estimates (ATE).

No classification for acute toxicity oral and acute dermal is warranted under CLP Regulation (EC n. 1272/2008).
