Petrolatum composition
A petrolatum composition comprises from 10 to 60 wt % of a wax having an average number of carbon atoms per molecule of between 25 and 70, and having between 5 and 50 wt % branched paraffins in which the branches are selected from methyl and ethyl branches; from 10 to 60 wt % of a linear paraffin having an average number of carbon atoms per molecule of between 10 and 20; and optionally, a low melt wax. The petrolatum composition has a drop melt point of from 35° C. to 80° C.
