Hereunder is the response to your query subject to disclaimer: The alcohol used is denatured alcohol, which is industrial methylated spirit or surgical spirit (contains natural or synthesised ethanol and denaturing agent such as methanol or methylisobutyl ketone). We regard it as permissible for use.
If the product contains denatured ethanol (definition: Make (alcohol) unfit for drinking without impairing usefulness for other purposes), then this product is permissible to use. All that remains to check is whether the product contains any animal ingredients.
