Xylitol is a common additive in foods and is a normal metabolite derived
from glucose. Butylated hydroxyanisole (BHA) is an antioxidant that is
commonly added to foods. Both are generally recognized as safe in the
amounts typically found in foods and chewing gums. Titanium dioxide is a
white compound that is generally inert. It is of concern when respired in a
particulate form (mainly by people with high exposure in industrial
settings). In this instance it causes lung damage by a mechanism that
involves free-radical production, similar to silica and other inhaled
particulate matter.
These compounds have a long history of use by large numbers of people and
they appear to be safe. I am not aware of any adverse interactions between
these compounds.
