Is Glyceryl Hydroxystearate vegetarian?

Glyceryl hydroxystearate, also known as glyceryl monohydroxystearate, is an organic compound with the molecular formula C21H42O5, formed by esterification of hydroxystearic acid with glycerol. It appears as a whitish or pale yellow powder and is used as an emulsifier and thickener in cosmetics and skin-care products; the hydroxystearic acid feedstock can be derived from plant oils (e.g. castor oil) or, less commonly, from animal fat.

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