  • Applications

    Aminexil (CAS 113275-13-1) is primarily associated with cosmetics and personal care, where it is used as an active ingredient in topical hair-care formulations to help support hair density; it is also evaluated as an intermediate or processing aid in industrial manufacturing and may be employed as a chemical building block in pharmaceutical synthesis; in polymers and plastics, it can be used as a functional additive or processing aid depending on the formulation. Use is subject to local regulations and formulation limits.
