简要总结
Patch test - This test is performed to assess the dermal safety of test product involved in the
study. It is a technique used to determine the potential of specific substances to cause irritancy
of the skin. Irritants are substances that damage the skin by direct toxic action. The damage
will depend upon the nature of the irritant, its concentration, and duration of exposure.
Irritation is manifested as inflammatory responses such as erythema (redness), oedema
(swelling), vesiculation and finally to an intense suppurative reaction without the involvement
of immune system.
In general, patches are applied for a contact period of 24 hours, and skin reaction is assessed
under a constant artificial daylight source and the marked site is scored post 24 hours after the
removal of the patches. Reactions such as erythema, dryness and wrinkling are scored on a 0
– 4-point scale and oedema is scored on another 0 – 4-point scale (Draize scale).
Result: The study was completed as per protocol with 52 complete cases.
