In September 2011 we received an email from a long-time VRG member asking us to look into two ingredients she believed were mislabeled in skin care products she had seen at a store located close to Philadelphia. She told us that “silk amino acids” were listed as ingredients in products labeled “vegan.”
The VRG contacted James Youn of Worldway, a Korean company which produces silk amino acids for both food and cosmetic purposes. He told us that “we use only empty cocoons” in the production of silk amino acids. Silk amino acids may be found in some food supplements sold in the United States but, to the best of our knowledge, is not in any food products.
Interested readers may note that some Internet sources stated that silk worms were killed in the extraction process to obtain silk amino acids.
