Sr-(Tetrapeptide-74 Hexapeptide-40 Expression Vector Pmbp-Parallel 1 Polypeptide-1 Spider Polypeptide-1 Spider Polypeptide-5)
A cosmetic ingredient used as adhesive, antioxidant, binding in skincare, haircare, and personal-care products sold in the European Union.
What is it?
sr-(Tetrapeptide-74 Hexapeptide-40 Expression Vector pMBP-parallel 1 Polypeptide-1 Spider Polypeptide-1 Spider Polypeptide-5) is a single chain fusion peptide, produced by fermentation in E. coli. The starting gene is synthesized by the fusion of the gene from Tetrapeptide-74, Hexapeptide-40, sr-Expression Vector pMBP-parallel 1 Polypeptide-1, sr-Spider Polypeptide-1 and sr-Spider Polypeptide-5. The fusion peptide contains 1003 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.
What does it do?
Sr-(Tetrapeptide-74 Hexapeptide-40 Expression Vector Pmbp-Parallel 1 Polypeptide-1 Spider Polypeptide-1 Spider Polypeptide-5) is listed in the EU cosmetic ingredient inventory with the following declared functions:
-
Adhesive
binds materials together — used in long-wear cosmetics like false lashes and certain eye makeup
-
Antioxidant
