Diaminopyrimidine oxide

Diaminopyrimidine oxide (CAS 74638-76-9), commercially recognized as Aminexil and Kopexil, is an active ingredient used in topical scalp and hair care formulations. It targets the perifollicular collagen structure to help maintain hair anchoring, making it a sought-after functional ingredient for anti-hair loss product development.

Aminexil is the primary active in leave-on scalp serums, ampoules, and treatment lotions designed to address hair thinning and premature hair loss. Formulators incorporate it into professional salon treatments and retail anti-hair loss ranges, often in combination with other actives such as minoxidil or niacinamide.

Kopexil is also used in shampoo and conditioner formats where a scalp-conditioning benefit claim is required for the specific product line. Cosmetic brands targeting the dermocosmetic and trichology segments source this ingredient to substantiate clinical efficacy claims on finished products.

Diaminopyrimidine oxide is typically supplied as a white to off-white powder or as a pre-dispersed solution for ease of formulation in industrial settings. Cosmetic-grade material is the standard commercial specification, with purity levels commonly at 99% or higher for bulk quantities and research samples.
