Is Dipalmitoyl Hydroxyproline vegan?

Dipalmitoyl Hydroxyproline is an ester of hydroxyproline (an amino acid) with two palmitic acid chains, used in skin care as a conditioning and anti-aging agent. Hydroxyproline can be derived from collagen (animal origin) or produced synthetically, so its origin is uncertain without manufacturer confirmation.

An ingredient is considered vegan if it contains no animal-derived components at any point in its production.
