Is Polyquaternium-57 vegetarian?

Polyquaternium-57 is a cationic polymer formed from a ricinoleic acid amidopropyltrimethylammonium chloride derivative, castor oil, isostearic acid, and succinic acid. Note: despite plant-based castor oil content, this polymer class as named commonly relies on animal tallow-derived quaternary ammonium precursors in some manufacturing pathways, though castor-oil based routes exist; sourcing should be confirmed per manufacturer.

An ingredient is considered vegetarian if it avoids components derived from killing an animal.
