Aminexil

Aminexil (CAS 113275-13-1), also marketed under the name Kopexil, is an active ingredient developed for use in scalp and hair care formulations. It targets the progressive rigidification of the hair follicle sheath.

This mechanism is associated with hair loss, making it a recognized functional ingredient in anti-hair loss product development. Aminexil is incorporated into leave-on scalp treatments, serums, and ampoules.

These products are designed to address androgenetic and diffuse hair thinning in both professional and retail hair care lines. It is frequently combined with other actives such as minoxidil or niacinamide.

In multi-action anti-hair loss formulations, each ingredient targets a distinct biological pathway. Cosmetic brands use it to substantiate efficacy claims in clinical-style positioning for premium hair care.

This supports product differentiation in the competitive market segment. In pharmaceutical-adjacent topical products, it is evaluated for its role in prolonging the anagen phase of the hair growth cycle.

The product is supplied as a white to off-white crystalline powder. It is available in cosmetic-grade specification suitable for topical formulation, with purity levels typically confirmed by HPLC.

Standard packaging ranges from small research quantities to kilogram-scale commercial orders. This flexibility supports both initial development and full-scale production needs for chemical manufacturers.
