Is Silkworm Cocoon/rh-Polypeptide-150 Extract vegan?

Silkworm Cocoon/rh-Polypeptide-150 Extract is an extract derived from the cocoons of the silkworm, Bombyx mori, combined with a recombinant human-like polypeptide (rh-Polypeptide-150) produced via biotechnology. It is used in cosmetics primarily for its skin-conditioning and film-forming properties. Because the silk cocoons are typically harvested by killing the silkworm pupae inside, this ingredient is generally considered not vegetarian and not vegan.

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