Mineral based means what exactly, oil based? Like mineral oil?

Only the manufacturer can give you a breakdown of the components in the product. I can only attest to its effectiveness on granite. It was recommended by an excellent stone fabricator In North Carolina. In moving to another state, that fabricator did not seal the granite properly. This product (which we applied ourselves) did the job! I will probably reapply on heavily used areas in another year just to protect the granite.

Can this be used on slate tile?

It can be used on any natural stone, although some are more difficult to seal than others.

Please tell me how often it is necessary to reapply this sealer. Thanks.

I plan to reseal heavily used areas about every 16-18 months

Nowhere on the container does it say it is food grade. I do know it is a product made in Italy. It has a telephone number listed. #39 045 688 7593. Fax #39 045 686 2456 Hope this helps.
