  • Applications

    Potassium Caproyl Tyrosine (CAS 630121-95-8) is the potassium salt of caproyl tyrosine; in real-world use, it is primarily evaluated as a specialty ingredient in cosmetics and personal care as a skin-conditioning agent and a source of tyrosine-derived moieties, and can serve as an intermediate in the synthesis of peptide-like actives and biocompatible polymers. In industrial manufacturing, it may function as a formulation stabilizer and/or a chelating agent, and as a building block for specialty polymers containing amino acid–derived functionalities; in coatings, inks, and adhesives, it can be used as a functional additive to impart amino-acid derived functionalities and improve compatibility with bio-based resins. Additionally, it may appear as an intermediate for pharmaceutical active ingredients or excipients, depending on local regulations and formulation parameters.
