Description of key information
In a skin irritation/corrosion study (conducted according to OECD Guideline 404, EU Method B.4 and EPA OPPTS 870.2500 and in accordance with GLP), three rabbits were dermally exposed, under semi-occlusive conditions to HES10108 (Supplied as DOW CORNING® BY 16 -122 B) at a dose of 0.5 ml for 4 hours and evalauted for skin irritation/corrosion effects.
Under the conditions of the present study, the single dennal application of the test item HES10108 (Supplied as DOW CORNING® BY 16-122 B) to three rabbits at a dose of 0.5 mL showed neither irritant nor corrosive effects.
Neither mortalities nor significant clinical signs of toxicity were observed.
According to Annex I of Regulation (EC) 1272/2008, the test item HES10108 (Supplied as DOW CORNING® BY 16-122 B) does not have to be classified and has no obligatory labelling requirement for skin irritation and according to GHS (Globally Harmonized Classification System), the test item HES10108 (Supplied as DOW CORNING® BY 16-122 B) has no obligatory labelling requirement for skin irritation.
In a eye irritation/corrosion study (conducted according to OECD Guideline 405, EU Method B.5 and EPA OPPTS 870.2400 and in accordance with GLP), three rabbits were administered a single ocular application of HES10108 (Supplied as DOW CORNING® BY 16 -122 B) at a dose of 0.1 ml and evalauted for ocular irritation/corrosion effects.
Under the conditions of the present study, a single ocular application of the test item HES10108 (Supplied as DOW CORNING® BY 16-122 B) to rabbits at a dose of 0.1 mL produced slight irritant effects, which were fully reversible within 48 hours in animals no. 1 and no. 2 and within 72 hours in animal no. 3. Neither mortalities nor significant clinical signs of toxicity were observed.
According to Annex I of Regulation (EC) 1272/2008 [9], the test item HES10108 (Supplied as DOW CORNING® BY 16-122 B) has no obligatory labelling requirement for eye irritation and according to GHS (Globally Harmonized Classification System) [10] the test item HES1 01 08 (SuJJJJlied as DOW CORNING® BY '16-'122 B) has no obligatory labelling requirement for eye irritation
