Kopexil Aqua
DIAMINOPYRIMIDINE OXIDE OXOTHIAZOLIDINECARBOXYLATE
Water-soluble salt of Diaminopyrimidine Oxide (DPO) and Oxothiazolidinecarboxylic Acid (OTZ). Acts via lysyl oxidase inhibition and anti-perifollicular fibrosis to restore follicular cycling and hair density, with added potassium channel opening activity.
Kopyrrol Aqua
PYRROLIDINYL DIAMINOPYRIMIDINE OXIDE OXOTHIAZOLIDINECARBOXYLATE
Water-soluble salt of Pyrrolidinyl Diaminopyrimidine Oxide (PDPO) and Oxothiazolidinecarboxylic Acid (OTZ). A potassium channel opener that promotes hair growth through vasodilation, Wnt/β-catenin activation, and reduction of TGF-β1 in the scalp.
Overview
The OTZ Salt Advantage
Many potent cosmetic actives are poorly water soluble in their free base form, limiting their practical use in modern aqueous formulations. By pairing these actives with Oxothiazolidinecarboxylic Acid (OTZ), Mironova Labs creates salt forms that dissolve freely in water while preserving full biological activity.
The OTZ counterion is not merely a solubilizing agent — it is itself a cysteine precursor with established antioxidant and keratin-supporting properties, making each salt a dual-active ingredient.
Why OTZ Salt Forms?
