E470b refers to magnesium salts of fatty acids, used as emulsifiers and anti-caking agents. The fatty acids can be sourced from either animal fats or vegetable oils. Magnesium stearate is the most common example.

Why unconfirmed?

Magnesium Salts of Fatty Acids can be either derived from animal, or non-animal sources. The ingredient name itself is identical either way, so the label alone can’t tell you which. Only a supplier declaration can.
