简要总结
Study was designed to test the safety of topical products provided by Dabur India Limited on healthy human subjects. 24 subjects were enrolled in the study, and all the subjects completed the study. The study was conducted over a period of approximately 9 days for each subject. 40 micro litre of the test product was patched on the back of the subject perceived to have sensitive skin , under occlusion for 24 hrs. The skin was evaluated for signs of irritation identified under Erythema and odema, using Draize’s scale.
After patch removal, skin was observed for irritation reactions at 0 hr, 24 hrs post patch removal for immediate reactions and 7 days post patch removal for delayed reactions. As per Draize scale for scoring irritation, all the investigational products emerged as non irritant products when observed at Ohr, 24 hours and 7 days post patch removal.
All the test products were deemed to be dermatologically safe as per their classification into non irritant category at all time points of evaluation by 24 hrs occlusive patch test method (reference BIS 4011:1997). SLS was used as positive control in the study was confirmed as irritant when observed at Ohr & 24hrs and was confirmed as mild irritant when observed at 7 days post patch removaL
