Results and discussion
- Results of examinations:
- - Induction results: 59 slight, one moderate and one severe erythema reactions occurred during the two week induction period.
- Challenge results: Seven light erythema reactions were seen at 24 hours after the challenge patch application, with one slight erythema reaction at the 48 hour observation and by 72 hours, all eight sites were negative.
Applicant's summary and conclusion
- Conclusions:
- Undiluted stick deodorant formulation containing 7 % sodium stearate was applied four days a week for two weeks as eight 12-hour patches to the medial surface of the upper arm of 212 subjects causing 59 slight, one moderate and one severe erythema reactions. A 24-hour challenge patch was then applied after two weeks rest and seven light erythema reactions were seen at 24 hours, with one slight erythema reaction at the 48 hour observation and by 72 hours, all eight sites were negative.
- Executive summary:
Undiluted stick deodorant formulation containing 7 % sodium stearate was applied four days a week for two weeks as eight 12-hour patches to the medial surface of the upper arm of 212 subjects causing 59 slight, one moderate and one severe erythema reactions. A 24-hour challenge patch was then applied after two weeks rest and seven light erythema reactions were seen at 24 hours, with one slight erythema reaction at the 48 hour observation and by 72 hours, all eight sites were negative. No information on the test methods used is available in the publication (CIR 1982). However, this information is taken from a peer reviewed article and can be considered adequate for use for this endpoint.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
