- Photoperiod (hrs dark / hrs light): Artificial light, sequence being 12 hours light, 12 hours dark
IN-LIFE DATES: From: 18-July-2016 To: 4-August-2016
Test system
- Type of coverage:
- semiocclusive
- Preparation of test site:
- clipped
- Remarks:
- Approximately 24 hours (animals no. 1 and no. 2) and 23 hours (animal no. 3) before the test, the fur was removed from the dorsal area of the trunk by using an electric clipper. Care was taken to avoid abrading the skin.
- Vehicle:
- unchanged (no vehicle)
- Controls:
- other: The untreated other side served as control
- Amount / concentration applied:
- A dose of 0.5 mL of the test item was applied to each test site
- Duration of treatment / exposure:
- The test item was held in contact with the skin throughout a 4-hour period. At the end of the exposure period, the residual test item was removed with physiological saline 0.9% NaCI.
- Observation period:
- The animals were observed for 72 hours after the patch removal
- Number of animals:
- The test item was not expected to produce corrosion, but might be irritating. Therefore, a single patch was applied to one animal for 4 hours. Subsequently, the reminder 2 rabbits were exposed derammly.
- Details on study design:
- TEST SITE
The test item was applied at a single dose to a small area (approximately 6 cm2) of skin on one side of the dorsal area and covered with a gauze patch, which was held in place with a non-irritating tape. The untreated other side served as control. The test item was applied to the patch first and then applied to the skin. The patch was fixed with a semi-occlusive dressing. The limits of the application site were marked with an ink marker
REMOVAL OF TEST SUBSTANCE
At the end of the exposure period, the residual test item was removed with physiological saline 0.9% NaCI.
OBSERVATION TIME POINTS
The animals were examined for signs of erythema and oedema 1 hour after the patch removal. For the determination of classification-relevant values, the animals were examined for signs of erythema and oedema 24, 48 and 72 hours after the patch removal.
SCORING SYSTEM:
- Method of calculation: Dermal irritation was scored and recorded according to the grades as per Draize score

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Under the conditions of the present study, the single dennal application of the test item HES1 01 08 (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.
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. - Executive summary:
In this 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.
