Are Silk Amino Acids Protein
Hydrolyzed from pure silk fibers, silk amino acids have a lower molecular weight than hydrolyzed silk protein powders as they undergo a greater degree of hydrolysis. Due to their smaller molecular weight they are more penetrating and moisturizing to skin and hair. Silk is taken from the cocoon of the silkworm moth (Bombyx mori). After the silk thread is isolated from the vacant cocoon, the fibers are cleaned and degummed. The individual silk fiber, too fine to handle individually, is then wound with other fibers onto a reel creating one long, strong thread. The threads are then combed to remove the noils. Noils, by-products of the textile industry, are short fibers combed from the long fibers during the preparation of the silk thread. These noils are used in the production of silk proteins.
