The mean initial body weight at the start of the study was 328 g (range from 302 to 372 g).
In a large number of tests, with a variety of test materials, the guinea pig and the specific strain used has proven to be a species well suited for skin sensitization studies.
Identification and adaption
Healthy young animals were allocated to the study groups at least 7 days before dosing to allow for acclimatization. The guinea pigs were identified by earmark and color.
Assignment
20 guinea pigs were used in this study.
Pretest: 5 females
Group 1: negative control group (5 females)
Group 2: test material group (10 females)
- Housing:
Five guinea pigs were housed in type GMI5 (EBECO) Makrolon cages with a shelter and placed on mobile racks. The animals were kept on conventional softwood granulate as the bedding. The bedding was changed two times a week.
- Diet (e.g. ad libitum):
Diet and community tap water from Makrolon drinking bottles were available to the guinea pigs ad libitum.
The diet, Provimi Kliba 3418.0, was checked according to the specifications of the manufacturer by independent laboratories. Analysis included both qualitative and quantitative evaluation for heavy metals, aflatoxins, pesticides and antibiotics. The tap water was analyzed periodically according to the German regulations for human drinking water. The softwood granulate was analytically checked by independent laboratories.
ENVIRONMENTAL CONDITIONS
Temperature and atmospheric humidity were measured by a thermohygrograph. The room temperature within the study period was 20 to 21 °C and the relative atmospheric humidity 53 to 63%.

-- Observations
During the induction phase, the guinea pigs were examined on days 2, 3, 7, 11, 12, 15, and 22 of the experimental part for local skin reactions and the results were documented.
The behavior and general condition of all animals were monitored daily. The challenge sites were investigated for reactions 48 hours after start of the challenge. Further inspections followed 72 hours after start of the challenge, to detect weak or slowly developing reactions.
After the challenge, skin changes at the application sites were evaluated according to the following MAGNUSSON and KLIGMAN scheme. - Positive control substance(s):

- Executive summary:
Purpose
The purpose of this GPMT assay was to identify the contact allergenic potential of teh test material. This study should provide a rational basis for risk assessment to the sensitising potential of the test item in man.
Study Design
The test material was investigated for skin sensitizing properties in the guinea pig maximization test according to MAGNUSSON and KLIGMAN (1969). 5 females were treated with the vehicles NaCl solution (100 g/L) (group 1) and 10 females were treated with the test material (group 2). Induction included intradermal injection of test material preparation (5 g/L) in NaCl solution with and without Freund's complete adjuvant on experimental day 1, and topical application of test material preparation for 48 hours on experimental day 8. Challenge by topical application of the test material preparation (25 g/L) for 24 hours was performed two weeks after topical induction and readings were taken at 48 hours and 72 hours after start of treatment.
Results
After challenge, no positive reactions in the test material treated skin sites at the first reading were seen. At the second reading one animal showed positive reaction. This results in 10 % positive reactions after challenge.
Conclusion
Under the given experimental conditions, the test material induced no reactions. According to EU Regulation No. 1272/2008 (CLP), the test material is not classified as a skin sensitizer.
