with my guess of corn. Here is an amazing (a-maize-ing?) list of items from corn, which includes most of the items on your list (all if you allow "cosmetics" to include some of the specific items from your list, "coatings" to include paint, and figure that Twinkies are almost certainly sweetened with corn syrup),

Nice trivia. Thanks.
