Additional information

The physical state and appearance of the test material was reported as part of a study conducted in accordance with standardised guidelines and under GLP conditions to determine the reactivity of the test material towards model synthetic peptides containing either cysteine (SPCC) or lysine (SPCL) for the purpose of informing on the skin sensitisation potential of the test material. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).

Under the conditions of this study, the test material was reported to be a white powder.
