Applicant's summary and conclusion

Interpretation of results:
other: Not irritating
Remarks:
Criteria used for interpretation of results: EU
Conclusions:
A 24-hour application of undiluted Santicizer 261 was not irritating to the intact and abraded skin of six albino rabbits.
Executive summary:

Undiluted Santicizer 261 (0.5 mL) was applied to the intact and abraded skin of six New Zealand albino rabbits for 24 hours. The animals were assessed for signs of irritation during the 7-day observation period, and the data scored according to the method of FHSA. Erythema (score of 1) was seen on the abraded and intact skin sites in all six rabbits, 24 hours after removal of the test material. No erythema was noted when assessed at 4, 48, 72 and 168 hours after removal of the test material, and no oedema was reported during the 7-day observation period. The investigators classed the test material as non-irritating when applied to the intact and abraded skin of rabbits. Under EU CLP regulations, this study would indicate that Santicizer 261 is not irritating to the skin.
