Is Silica Polysilsesquioxane Propyldisulfideacetyl Pentapeptide-4 vegetarian?

Silica Polysilsesquioxane Propyldisulfideacetyl Pentapeptide-4 is a silica material condensed with 3-mercaptopropyltrimethoxysilane, whose mercaptan groups are coupled to Pentapeptide-4 via a thioglycolic acid-formed disulfide linkage. Its vegan status depends on the synthetic origin of the peptide, which is typically synthetic but could theoretically be uncertain in sourcing.

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