Endpoint summary

Description of key information

The in vivo skin irritation study with the rabbit revealed slight to moderate formation of erythema and very slight edema formation, with all effects being fully reversible and below the threshold of significance. In the two in vivo eye irritation studies with the rabbit very slight conjunctivae redness was observed below the threshold of significance, the effect was fully reversible. BMDBM therefore is not to be considered as skin irritant or eye irritant.

Irritant / corrosive response data:

After 4 h application of BMDBM (as 10 % solution in ethanol / 2-phenylethanole 50/50) to intact or abraded rabbit skin, no to well-defined erythema were observed, resulting in a mean score of 0.67 and 1.17 for intact and abraded skin, respectively. Edemas were less pronounced, showing no to very slight response with mean values of 0.11 and 0.83 for intact and abraded skin, respectively.
When testing the solvent solely, the mean irritation scores for erythema formation were 0.56 and 1.00 for intact and abraded skin, respectively. The edema scores were 0.00 and 0.78 for intact and abraded skin, respectively.
These results indicate that the substance tested possesses a slight irritating potential which is mainly caused by the solvent used.

Interpretation of results:

GHS criteria not met

Conclusions:

Occlusive application of 10 % butyl methoxydibenzoylmethane (BMDBM) in ethanol / 2-phenylethanol for 4 h to intact or abraded rabbit skin caused no to slight erythema and edema. Also the vehicle ethanol / 2-phenylethanol (50/50) causes these effects but in a somewhat lower potency.

Executive summary:

After occlusive application of 0.5 mL of the test item (10 % BMDBM solved in ethanol / 2-phenylethanol (50/50)) for 4 hours to intact or abraded rabbit skin, no to moderate formation of erythema and no to very slight edema formation was noted. The mean scores (erythema/edema) were 0.83/0.17 on intact skin and 1.33/1.00 on abraded skin 24 h after application. Testing the solvent caused no to very slight erythema and edema resulting in scores (erythema/edema) of 0.50/0.00 on intact skin and 1.17/1.00 on abraded skin 24 h after application. It can therefore be concluded that the skin irritations are mainly due to the vehicle used and that BMDBM bears very slight irritating potential. As the erythema/edema score is <2.3 in all animals no classification as skin irritant according to GHS and CLP is needed.

Irritant / corrosive response data:

As given above, single application of a 5 - 20 % solution of BMDBM in diethylphtalate caused weak shortlasting conjuncticval irritation of the rabbit eye. No alteration of the cornea was observed macroscopically.

Other effects:

No further effects were reported.

Interpretation of results:

GHS criteria not met

Conclusions:

The 20 % solution of butyl methoxydibenzoylmethane (BMDBM) dissolved in diethylphtalate caused weak shortlasting conjunctival irritation of the rabbit eye. No alterations of the cornea was observed macroscopically. Therefore, BMDBM can be considered as non-irritant to the eye and no classification according to EU CLP is needed.

Executive summary:

The determination of eye irritating effects of butyl methoxydibenzoylmethane (BMDBM) was performed in a study similar to OECD Guideline 405 on three rabbits: BMDBM as 5 %, 10 %, and 20 % solution in diethylphtalate was placed in the conjunctival sac of one rabbit eye and the effects are recorded after 1 h, 24 h, 48 h, 72 h, 7 days and 14 days. Observations comprised opacity of the cornea, iris reaction, conjunctival redness and swelling (chemosis).

The instillation of a solution of BMDBM caused concentration-dependent weak conjunctival irritation of the rabbit eye which was fully reversible within up to 3 days. The mean irritation scores for the 20 % solution (3 animals, 24 - 72 h after administration) were 0 (Cornea opacity), 0 (Iris), 0.67 (Conjunctivae redness), 0 (Chemosis). Therefore, BMDBM can be considered as non-irritant to the eye and no classification according to EU CLP is needed.

Conclusions:

Application of 100 mg sunscreen cream 260587/E, containing 3 % BMDBM, into the rabbit eye caused an overall irritation score of 0.4 (1 - 72 h). The mean scores 24 - 72 h after administration were 0 (Cornea opacity), 0 (Iris), 0.2 (Conjunctivae redness), 0 (Chemosis). The effects were fully reversible within 48 h.
Therefore, the test item sunscreen cream 260587/E, containing 3 % BMDBM can be considered as non-irritant to the eye and no classification according to GHS and CLP is needed.

Executive summary:

Under the conditions of this experiment, sunscreen cream 260587/E, containing 3 % BMDBM, was found to cause a primary irritation score of 0.4 (1 - 72 h), when applied to the rabbit eye mucosa.

The individual mean scores 24 - 72 h after administration were 0 (Cornea opacity), 0 (Iris), 0.2 (Conjunctivae redness), 0 (Chemosis). The effects were fully reversible within 48 h. No staining of the cornea and conjunctivae of the treated eyes by pigment or colouring of the test article was observed. No corrosion was observed at any of the measuring Intervals.

Therefore, the test item sunscreen cream 260587/E, containing 3 % BMDBM can be considered as non-irritant to the eye and no classification according to GHS and CLP is needed.

Additional information

Skin irritation:

In the study by Kleczak (1982), skin irritation was tested by occlusive application of a 10 % BMDBM solution for 4 h on intact or abraded rabbit skin. The results revealed slight to moderate formation of erythema and very slight formation of edema belowthe level of significance. Testing the solvent caused no to very slight erythema and edema formation. Therefore, the authors concluded that the irritating potential can mainly be attributed to the solvent used and that BMDBM is at best slightly irritating to skin.

 

Eye irritation:

In two studies by Kleczak (1988 and 1978), eye irritation was tested in the rabbit eye. Both test items, which were a sunscreen cream containing 3 % BMDBM and different BMDBM solutions (5 - 20 % BMDBM), caused only very slight conjunctival redness below the level of significance (grade 1 of 4) which was fully reversible within 2 - 3 days. Therefore, BMDBM can be considered as not irritating to the eyes.

Justification for classification or non-classification

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008

The available experimental test data are reliable and suitable for classification purposes under Regulation (EC) No 1272/2008. As a result the substance is not considered to be classified for skin corrosion/irritation and eye damage/irritation under Regulation (EC) No 1272/2008, as amended for the twelfth time in Regulation (EU) 2019/521.
