Acute toxicity

Based upon the study results and available information, the substance aluminium,4,5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfop henyl)azo]-1H-pyr azole-3-carboxylic acid complex (tartrazine) is not expected to show acute toxicity effect by the oral, inhalation and dermal route and thus will not be considered for further classification.

 

Irritation / corrosion

Skin Irritation: Administration of aluminium, 4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex to rabbit resulted in a mild skin irritation effect which is not adequate for classification as a skin irritant. Therefore, it can be concluded that aluminium, 4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex is not irritating to skin of rabbit.

 

Eye irritation: The modified maximum average score (MMAS) from QSAR eye irritation score of aluminium, 4, 5-dihydro-5-oxo-1- (4-sulfophenyl) -4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex is estimated as 20.2. This score indicates that aluminium, 4, 5-dihydro-5-oxo-1- (4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex is not irritating to the eye of rabbit.(as the criteria MMAS <25 is not irritating).

 

Sensitisation

 The substance aluminium,4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex(Tartrazine Lake) was found to be a not sensitising to rabbit skin.

Additional information - General Population

Aluminium, 4,5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl)azo]-1H-pyrazole-3-carboxylic acid complex (Tartrazine yellow, aluminium lake)does not exhibit acute toxicity by oral, dermal and inhalation route. It is assumed to be non-irritating to the skin of humans and eye of rabbits, is not genotoxic and is not a developmental or reproductive toxin.  In the absence of local effects following short-term or long-term exposure, no dose-response data are available and a quantitative dose descriptor is not derived. DNEL values for local exposure are therefore not calculated.

 

In the absence of acute systemic toxicity, no dose-response data are available and a quantitative dose descriptor is not derived. DNEL values for acute systemic effects are therefore not calculated.

 

A standard approach to deriving DNEL values would be to use the reproductive toxicity dataset and apply assessment factors as described in ECHA guidance documents. The critical endpoint is considered to be the NOAEL of 100000 mg/kg body weight by oral route.
