What it is

How it is used in food
Gives a smooth, moisture-proof coat that keeps a tablet intact until it is swallowed.

Health and safety
None known at the levels used; the polymer is too large to be absorbed and passes through intact.
Molecules this large are not absorbed from the gut, which is why they carry very low toxicity and why EFSA generally sets no numerical ADI for them.
