Additional information

Skin irritation / corrosion:

One Klimisch score 2 study was available for dermal irritation and was used as a key study. In this study (1976), Rhodiantal IBCH (100% (as such) and 30% (diluted product in vaseline oil) has been applied to the intact and abraded skin of six rabbits. Period of observation: 24 and 72 hours. No more information is available. For the concentration of 100%, the mean scores (24 and 72h) were 0.66 for erythema and 0 for edema on the intact skin. Based on this score the substance is slightly irritating to rabbit’s skin. According to the UN GHS and CLP criteria, the substance is not classified for the skin irritation.

Eye irritation:

One Klimisch score 2 study was available for dermal irritation and was used as a key study. In this study (1976), Rhodiantal IBCH (100% (as such), 30% and 10% (diluted product in vaseline oil) has been instilled in eye rabbits. Period of observation: 7 days. No more information is available.

For the concentration 100%, mean scores (24, 48 and 72h) were 0.05 for chemosis, 0.44 for conjunctival redness, 0.38 for iritis and 0.22 for corneal opacity. Based on this score the substance is slightly irritating for eyes in rabbit. According to the GHS and CLP criteria, the substance is not classified for the eye irritation.

Justification for classification or non-classification

Harmonized classification:

No harmonized classification is available according to the Regulation (EC) No 1272/2008.

 

Self classification:

Phenol, 2-methoxy-, reaction products with 2,2- dimethyl-3-methylenebicyclo[2.2.1]heptane, hydrogenated is not classified for skin and eye irritation according to the Regulation (EC) 1272/2008 (CLP) and to the Directive 67/548/EEC.
