seventh generation dishwasher detergent gel for baby bottles?

is this safe for baby bottles? I bought the seventh generation "natural dishwashing liquid" before and bought the "dishwasher detergent gel" by mistake. when I opened it, it has a very chemical smell to it. but, at the back it still states that it is mostly a plant based product. is it safe to use for baby bottles? my LO is 9 months old.
