Description of key information
No evidence of sensitisation.
Additional information
2 products, paper undyed and paper dyed by Brown HM 2763, were tested to determine their ability to sensitize the skin of normal volunteer subjects using an occlusive repeated insult patch test. 104 subjects completed the study. Under the conditions employed in this study, there was no evidence of sensitization to either of the products tested.
