Is Silkworm Oligopeptide-2 vegetarian?

Silkworm Oligopeptide-2 is a single-chain peptide of 14 amino acids derived from fibroin heavy chain protein found in silkworm silk. It is typically obtained by hydrolysis of silk protein sourced from the cocoons of the silkworm Bombyx mori, a process that generally involves killing the pupae inside.

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