: : NON-TOXIC FINISHES FOR CUTTING BOARDS, SALAD BOWLS, AND TOYS
: :
: : There are several options for finishing a cutting board or anything that requires a non-toxic finish (toys for example).
: : You can use a special cutting board oil or salad bowl finish. Behlens Salad Bowl Finish is one product that is safe for food contact after drying.
: : Walnut oil is another option. It is a true drying oil that reacts with the air and hardens, it is available grocery stores or some mail order woodworking supply stores.
: : Shellac is non-toxic when it is dry according to the A.F. Suter Co. (one of the world leaders in shellac production), in fact shellac is used by pharmaceutical companies as a pill coating and it is used in candy and fruit coatings.
: : Pure Tung Oil is non toxic if it doesn't contain dryers or solvents. Don't use tung oil products that are mixtures containing toxic dryers dyes or solvents.
: : Watco says its oils are safe for food or toy use after they've dried for 30 days
: : Water-based polyurethanes are often non-toxic when dry check the label to make sure.

: In Canada it is common to use Mineral oil for anything that has contact with food. It is edible (used as a laxitive) and does not go rancid as do most food oils
In the shop clas we have here my teacher tells us to use mineral oil for anything that comes in contact with food.
