Skin irritation / corrosion
Administrative data
- Endpoint:
- skin irritation / corrosion, other
- Remarks:
- in vivo study
- Type of information:
- other: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- 2008
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- As Hostapon SG and acylglycinate GCK-11-T differ only in the counterion (sodium-potassium), it can be assumed that the results obtained with Hostapon SG also apply to acylglycinate GCK-11-T.

Applicant's summary and conclusion
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- Hostapon SG as applied is not irritating to skin
- Executive summary:
The primary skin irritation potential of an aqueous solution of the registered UVCB substance (active content 25%) was investigated according to OECD test guideline no. 404. The test item was applied by topical semi-occlusive application of 0.5 mL to the intact left flank of each of three young adult New Zealand White rabbits. The duration of treatment was four hours. The scoring of skin reactions was performed 1, 24, 48 and 72 hours, as well as 7, 10 and 14 days after removal of the dressing. The mean score was calculated across 3 scoring times (24, 48 and 72 hours after patch removal) for each animal for erythema/eschar grades and for oedema grades, separately. The mean erythema/eschar score of the three animals was 1.33, 1.67 and 2.00, respectively and the mean oedema score was 1.00, 1.33 and 1.00, respectively. The application of Hostapon SG to the skin resulted in mild to moderate signs of irritation. These included erythema, oedema, scaling and dry / inelastic skin. In the male, these effects were reversible and were no longer evident 14 days after treatment. Both females were still observed with scaling of the skin on day 14 post treatment, the end of the observation period. The test item caused no staining of the treated skin. No corrosive effects were noted on the treated skin of any animal at any of the measuring intervals and no clinical signs were observed. Based on the results, the registered substance is not regarded a skin irritant according to EU classification criteria.
