Sr-(Polypeptide-167 Oligopeptide-178)

O que é?

sr-(Polypeptide-167 Oligopeptide-178) is a single chain recombinant peptide, produced by fermentation in Pichia pastoris. The starting gene is synthesized by the fusion of the gene from Polypeptide-167 and Oligopeptide-178. The fusion peptide contains 1000 amino acids which may contain disulfide bonds and/or glycosylation, and consists of the proper sequence of the 20 standard amino acids.

Para que serve?

Sr-(Polypeptide-167 Oligopeptide-178) consta no inventário UE de ingredientes cosméticos com as seguintes funções declaradas:

• Surfactant - emulsifying

  surfactant that forms and stabilises emulsions of oil and water — without it, creams and lotions would separate

• Film forming

  forms a thin continuous film on skin, hair, or nails — used in long-wear makeup, sunscreens, and hairsprays

• Skin protecting

  helps shield skin from external environmental factors

• Viscosity controlling

  adjusts the thickness or flow of a formulation
