Additional information
There are no data available on the acute dermal toxicity of D-Glucopyranose, oligomeric, butyl glycoside. In order to fulfil the standard information requirements set out in Annex VIII, 8.5, in accordance with Annex XI, 1.5, of Regulation (EC) No 1907/2006, read-across from structurally related substance is conducted following a category approach.
A detailed justification for the grouping of chemicals and read-across is provided in the technical dossier (see IUCLID Sections 7.1 and 13).
Oral
One acute oral toxicity study in rats is available for D-Glucopyranose, oligomeric, butyl glycoside. In this GLP-study, 6 female Sprague Dawley rats were exposed via gavage to a limit dose of 2000 mg/kg bw in a stepwise procedure (3 rats per step) according to OECD guideline 423 (Phycher Bio-Développement, 2008). No mortality and no adverse effects were observed up to the end of the14-day observation period. Based on the results, the oral LD50 value for female rats was greater than 2000 mg/kg bw. In accordance with OECD guideline 423, the oral LD50 cut-off of the test substance may be considered to be higher than 5000 mg/kg bw.
Dermal
No data are available on the acute dermal toxicity of D-Glucopyranose, oligomeric, butyl glycoside, but two reliable studies of the structurally related category members D-Glucopyranose, oligomeric, C10-16-alkyl glycosides and D-Glucopyranose, oligomers, decyl octyl glycosides (CAS 68515-73-1) exist, which were used for read-across based on the category approach.Both studies were performed according to OECD guideline 402 and in compliance with GLP.
In the acute dermal toxicity study with D-Glucopyranose, oligomeric, C10-16-alkyl glycosides, the test substance was applied at a limit dose of 2000 mg/kg bw on the skin of 5 male and female New Zealand White rabbits for 24 h. Clinical signs of partly hunched posture and slight depression occurred during the observation period. No mortality and no adverse effects including those on the skin were observed during the study period. Therefore, the dermal LD50 value of the test substance for male and female rabbits was greater than 2000 mg/kg bw (Hill Top Biolabs, 1989).
In a similar study performed with the category member D-Glucopyranose, oligomers, decyl octyl glycosides, no substance-related mortalities were observed after dermal application of the test substance at a limit dose of 2000 mg/kg bw in male and female New Zealand White rabbits. Test substance-related clinical changes of emaciation (2/5), nasal discharge (3/5), faecal stains (5/5), yellow area throughout the site of application (5/5) and lacrimation (1/5) occurred in the animals. Irritative effects on the skin in the form of moderate to marked erythema, mild to moderate edema, atopy, desquamation, and mild coriaceousness were most frequently observed within the animals. Based on the result of this study, the dermal LD50 value of the test substance for male and female rabbits was greater than 2000 mg/kg bw (Hill Top Biolabs, 1987).
Inhalation
This information is not available. The substance has a low vapour pressure and is marketed in aqueous formulation; therefore, exposure to vapours or dusts is not to be expected. In addition, reliable data from studies for acute toxicity via the oral route with the substance itself and for acute toxicity via the dermal route performed with structurally related substances according to Regulation (EC) No. 1907/2006, Annex XI, article 1.5 are available.
Justification for selection of acute toxicity – oral endpoint
There is only one study available.
Justification for selection of acute toxicity – inhalation endpoint
No study required since the substance has a low vapour pressure and is marketed in liquid form; therefore, human exposure to vapours or dusts is not to be expected.
Justification for selection of acute toxicity – dermal endpoint
Hazard assessment is conducted by means of read-across based on a category approach and weight of evidence from these studies.
Justification for classification or non-classification
The available data on the acute toxicity of D-Glucopyranose, oligomeric, butyl glycoside and structurally related substances according to Regulation (EC) No 1907/2006, Annex XI, 1.5 do not meet the criteria for classification according to Regulation (EC) No 1272/2008 or Directive 67/548/EEC, and are therefore conclusive but not sufficient for classification.
