Applicant's summary and conclusion

Interpretation of results:
other: not irritating
Conclusions:
Mild erythema and no edema was observed in rabbits during the 7 days of observation after treatment with propylene glycol oleate.
Hence, propylene glycol oleate can be considered not irritating to male albino rabbit skin.
Executive summary:

A Skin irritation study was conducted on albino male rabbit to assess the irritation potential of propylene glycol oleate.The animals were administrated of propylene glycol oleate (1% in tetraglycol: distilled water 1:1, with and without 1% lidocaine).

Propylene glycol oleate was administered to the backs (clipped of hair) of the rabbits in adhesive plasters with an exposure area diameter of 1.5 cm2. The test sites were kept under occlusion except when the dressing was removed on days 1, 3, 5, and 7 only long enough for observation. Then sterile pads were changed and the rabbit’s back reoccluded.

Mild erythema was observed in animals and no edema was observed during the 7 days of observation after treatment with propylene glycol oleate.

Hence, propylene glycol oleate can be considered not irritating to male albino rabbit skin.
