Sensitisation data (human)
Administrative data
- Endpoint:
- sensitisation data (humans)
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Study period:
- 12 May 2003 - 26 August 2003
- Reliability:
- 3 (not reliable)
- Rationale for reliability incl. deficiencies:
- other: This study was not conducted according to an OECD guideline or under GLP conditions, as it is a human study. No information is available on test concentration or vehicle, therefore the study was assigned Klimish 3.
Data source
Reference
- Reference Type:
- study report
- Title:
- Unnamed
- Year:
- 2 003
- Report date:

Materials and methods
- Type of sensitisation studied:
- skin
- Study type:
- study with volunteers
Test guideline
- Qualifier:
- according to guideline
- Guideline:
- other: Marzulli-Maibach sensitization technique
- Principles of method if other than guideline:
- 100 male or female volunteers (18-64 years) were exposed to the test article on the back during the induction phase 3 times/week for 48 hours for 3 weeks. Following a two week resting period, the subjects were challenged by application of test article for 24 hours on the induction and a control site. Skin reactions were scored immediately and 24, 48 and 72 hours after removal of the patches.

Results and discussion
- Results of examinations:
- SYMPTOMS
- Frequency, level, duration of symptoms observed: 2% of the subjects showed a positive skin reaction at the first reading (24 hours) after challenge. No reaction was noted at the 48 and 72 hrs reading in the test group and at any timepoint in the control group. Based on these results the substance was not considered to be sensitising.
