- Executive summary:
The study was carried out to assess acute toxicity following a single oral administration to rats of the test substance according to the OECD guideline 423. Wistar rats (Rattus norvegicus) were selected and maintained under controlled environmental conditions. Based on individual body weight, dosing of the test substance was calculated in mg/kg body weight (bw). Two groups of three female rats received 2000 mg/kg bw. Animals were observed for 14 days.
At the end of this period, no mortality or signs of evident toxicity were observed. Gross pathology examination was performed on all tested animals. No macroscopic alterations were observed in any of the major organs of the examined animals. Under the test conditions, the LD50 was found to be greater than 2000 mg/kg bw. Therefore, the test substance is not acutely toxic via the oral route.
Conclusion
LD50 > 2000 mg/kg bw

Additional information
ACUTE TOXICITY - ORAL ROUTE
The oral acute toxicity of Basic Blue 140 (BBl140) was tested with a single administration to rats, according to the OECD guideline 423. Wistar rats (Rattus norvegicus) were selected and maintained under controlled environmental conditions. Two groups of three female rats received 2000 mg/kg bw. Animals were observed for 14 days. At the end of this period, no mortality or signs of evident toxicity were observed. Gross pathology examination was performed on all tested animals. No macroscopic alterations were observed in any of the major organs of the examined animals. The LD50 was found to be greater than 2000 mg/kg bw. Therefore, the test substance is not acutely toxic via the oral route.
ACUTE TOXICITY - INHALATION ROUTE
No acute toxicity studies by inhalation route are available on BBl140.
Nevertheless, because of the physical state and the trade forms of the substance under registration, inhalation is not an appropriate route of exposure. Acute toxicity results for the other exposure routes indicate no concern.
ACUTE TOXICITY - DERMAL ROUTE
The inhalation and the skin contact of BBl140 are unlikely. Furthermore, because of the physical/chemical properties of the substance, the dermal absorption is expected as negligible.
According to the Commission Regulation (EU) 2016/863, amending Annexes VII and VIII to REACH Regulation (EC 1907/2006) as regards skin corrosion/irritation, serious eye damage/eye irritation and acute toxicity, testing by the dermal route does not need to be conducted if no systemic effects have been observed in in vivo studies with dermal exposure (e.g. skin irritation, skin sensitisation). Furthermore, it is explained that recent scientific analysis of available data from in vivo acute toxicity studies have shown that substances that are not toxic via the oral route may be expected with high certainty to be also non-toxic via the dermal route. Therefore, testing those substances via the dermal route does not provide essential information for their safety assessment.
The amendment is the consequence of studies and scientific debates. In particular, the 15th Meeting of Competent Authorities for REACH and CLP (CARACAL, 2014) concluded that an adaptation of point 8.5.3 of Annex VIII to REACH is justified in order to not require information on acute dermal toxicity for substances that have shown no toxicity in acute oral toxicity test up to the limit dose of 2000 mg/kg bw.
Furthermore, the acute dermal toxic potential was investigated for the Similar Substance 01, which was examined according to the OECD guideline 402. Groups of 5 male and 5 female Wistar rats received a single dermal dose of 2000 mg/kg body weight of the test item applied semiocclusively for 24 hours. The dose administered was tolerated by male and female rats without mortalities, toxicologically relevant clinical signs, toxicological effects on weight development and gross pathological findings.
BBl140 and Similar Substance 01 share the same phthalocyaninic core and, in both cases, they present a zwitterionic moiety formed by sulphonic acid, which conducts an acid function, and a tertiary amine on the sulphonaminic chain, characterized by a basic function. BBl140 presents a further sulphonaminic functionalization, of which chain ends with a tertiary amine that, based on the stechiometrical ratio reported in the analytical characterization, in most of the cases can be salified with acetic acid. It is expected that this difference has not a significant impact on the acute toxicity potential by dermal route.
The extend of percutaneous absorption of a substance depends largely on the physical and chemical properties of the substance itself. In particular, factors like the degree of ionization, molecular size and water and lipid solubilities influence penetration through the skin.
Local factors such as the pH, ambient temperature, blood perfusion and local anatomy also play a role. Taking into account the molecular size and the hydrophilic behaviour of both BBl140 and Similar Substance 01, it is not expected that dermal absorption occurred.
The read across approach has been further detailed in the report attached to the IUCLID section 13.

Justification for classification or non-classification
According to the CLP Regulation (EC 1272/2008), 3.1 Acute toxicity section, 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. Acute toxicity values are expressed as (approximate) LD50 (oral, dermal) or LC50 (inhalation) values or as acute toxicity estimates (ATE).
The oral LD50 value was established to be greater than 2000 mg/kg body weight, therefore the test substance is out of any classification limit for acute oral toxicity (oral acute toxicity category 4: 300 < ATE ≤ 2000 mg/kg bw).
Dermal and inhalation exposure is unlikely, thus no acute toxicity value is available and no further investigation is required.
In conclusion, the test substance is non classified for oral acute toxicity, according to the CLP Regulation (EC 1272/2008).
