Executive summary:

In a primary dermal irritation study similar to US FHSA Federal regulation: 16 CFR 1500.41, 6 rabbits were dermally exposed to 0.5 mL of 1,4 -BDDMA to approximately 2.5 cm² skin area. Two application sites per animal were treated, one site was left intact, the other was abraded. Test sites were covered with an occlusive dressing for 24 hours. Animals were observed for 72 hours. Irritation was scored similar to FHSA Federal guideline 16 CFR 1500.41. This scoring system is similar to OECD guideline 404.

No dermal irritation response was observed, neither at the intact nor at the abraded application sites.

In this study, 1,4 -BDDMA is not a dermal irritant..

Study performance does not comply with requirements of the relevant recent EU and OECD guidelines, where a less vigorous application regime with semi-occlusive dressing, an exposure period of 4 hours, treatment of only intact skin is stipulated.

Thus, it can be assumed, that a substance which shows no irritating activity under the application regime of guideline US FHSA Federal regulation: 16 CFR 1500.41 will also be non irritating under the application regimes of the relevant recent EU and OECD guidelines. Therefore the study is adequate for C&L purposes.

Executive summary:

In a primary eye irritation study similar to US FHSA Federal regulation: 16 CFR 1500.42 (similar to OECD guideline 405),

0.1 mL of 1,4-BDDMA was instilled into the conjunctival sac of the left eye of 6 New Zealand White rabbits without removing the test substance. Animals then were observed for 7 days. Irritation was scored by the method of Draize.

Transient conjunctival irritating effects were seen 1, 2 and 8 hours after application. All effects were completely reversible at the 24 h scoring. From 24 h onward all scores were zero.

In this study, 1,4-BDDMA is not an eye irritant.

Additional information

Reliable (RL= 2), relevant and adequate data are available for the skin and eye irritation potential of 1,4 -BDDMA.

Skin irritation

In a primary dermal irritation study similar to US FHSA Federal regulation: 16 CFR 1500.41, 6 rabbits were dermally exposed to 0.5 mL of 1,4 -BDDMA to approximately 2.5 cm² skin area. Two application sites per animal were treated, one site was left intact, the other was abraded. Test sites were covered with an occlusive dressing for 24 hours. Animals were observed for 72 hours. Irritation was scored similar to FHSA Federal guideline 16 CFR 1500.41. This scoring system is similar to OECD guideline 404.

No dermal irritation response was observed, neither at the intact nor at the abraded application sites.

In this study, 1,4 -BDDMA is not a dermal irritant.

Study performance does not comply with requirements of the relevant recent EU and OECD guidelines, where a less vigorous application regime with semi-occlusive dressing, an exposure period of 4 hours, treatment of only intact skin is stipulated.

Thus, it can be assumed, that a substance which shows no irritating activity under the application regime of guideline US FHSA Federal regulation: 16 CFR 1500.41 will also be non irritating under the application regimes of the relevant recent EU and OECD guidelines.Therefore, the study is adequate for C&L purposes.

 

Eye irritation

In a primary eye irritation study similar to US FHSA Federal regulation: 16 CFR 1500.42 (similar to OECD guideline 405), 0.1 mL of 1,4-BDDMA (according to supplier's information: purity ca. 90%) was instilled into the conjunctival sac of the left eye of 6 New Zealand White rabbits without removing the test substance. Animals then were observed for 7 days. Irritation was scored by the method of Draize.

Transient conjunctival irritating effects were seen 1, 2 and 8 hours after application. All effects were completely reversible at the 24 h scoring. From 24 h onward all scores were zero.

In this study, 1,4-BDDMA is not an eye irritant.

Based on the available information, 1,4 -BDDMA is not irritating to the eye and the skin. There are no data gaps for the endpoint irritation/corrosion. No human information is available for this endpoint. However, there is no reason to believe that these results would not be applicable to humans.


Justification for selection of skin irritation / corrosion endpoint:
Only one key study available; test procedure according to national (US) standard; study performed before implementation of GLP.

Justification for selection of eye irritation endpoint:
Only one key study available; test procedure according to national (US) standard; study performed before implementation of GLP.

Justification for classification or non-classification

Based on the available data, 1,4-BDDMA does not need to be classified for eye irritation or skin irritation according to regulation (EC) 1272/2008 or the former European directive on classification and labelling 67/548/EEC. Thus, no labelling is required.
