Danco 88693 Silicone Grease

In what way does your grease 88693 differ from your grease 80360? both seem to have the same product description and applications.

if it's food grade, why does it say keep out of reach of children?

What are ingredients, other than silicone?

Can this be applied to the o ring for the (whole house) water filter canister, I need something watertight but also I can take it apart every month.
