P11-4 is a synthetic, pH controlled self-assembling peptide used for biomimetic mineralization e.g. for enamel regeneration[1] or as an oral care agent. P11-4 (INCI name Oligopeptide 104) consists of the natural occurring amino acids Glutamine, Glutamic acid, Phenylalanine, Tryptophan and Arginine.[2] The resulting higher molecular structure has a high affinity to tooth mineral.[3] P11-4 has been developed and patented by The University of Leeds, (UK). The Swiss company credentis has licensed the peptide technology and markets it under the registered trademark CUROLOX TECHNOLOGY.
