A complex combination of hydrocarbons obtained from residual oils by solvent crystallisation and treated with hydrogen in the presence of a catalyst. It consists predominantly of saturated straight and branched chain hydrocarbons having carbon numbers predominantly greater than C25.
In a primary skin irritation study, the
intact skin of three male New Zealand albino rabbits was exposed to 0.5
milligrams of paraffin wax under semi-occlusive conditions for 4 hours.
Animals were observed for 72 hours, and skin irritation or corrosion was
scored by the method of Draize at 1, 24, 48, and 72 hours. At the end of
the 4 -hour test period, excess paraffin wax was removed with water.
Slight erythema was observed at 1 hour in all three animals which was
fully reversible by 24 hours. Therefore, under conditions of the study,
paraffin wax is considered not irritating.
This study received a Klimisch score of 1
and is classified as reliable without restriction because it is a
well-documented study report and closely followed OECD Guideline No. 404.
