Kirkland Organic Milk Is Kirkland Signature Organic Soy Milk Suitable For Vegans?

Is Kirkland Signature Organic Soy Milk suitable for vegans? - kirkland organic milk

I can make online information to find what was inside (ingredients), so I ask here.

I wonder whether the conservatives in Kirkland Soy Milk comes from animals. There are signature products of Kirkland vegan, or at least soy products?
