The Short Answer
Most commerically sold mustard has a preservative called Preservative 202, which is not present in ketchup. When the preservative comes in contact with a plastic bottle for an extended period of time at room temperature, it creates a slightly green residue, which is just mustard, with a little bit of a green tinge. There's nothing wrong with this, at all, but it's just not visually appealing for the customer, and may make them think there's something wrong with their perfectly good mustard. Try opening up a mustard bottle left at room temperature sometime, and you'll notice a faint green tinge at the edges. I know this because I used to work for a packaging company.
