P. contains 68-99% of isopropanol (isopropyl alcohol) by volume, the remainder consisting of water, with or without colour additives, suitable stabilisers, and perfume oils.

Stenbitsrom sells in much larger volume than Löjrom, but it has two drawbacks: it tastes little more than its salt and artificial additives, and the colour additives tend to bleed into other parts of the food you serve it with (such as a boiled egg), or to discolour the porcelain dish.
