Disodium Inosinate

What is Disodium Inosinate?

Disodium Inosinate is the disodium salt of inosinic acid, a naturally occurring purine nucleotide found in animal muscles, fish, and yeast extracts. Produced via fermentation or chemical synthesis, it serves in skincare formulations like creams, lotions, and serums within the moisturizer and conditioner categories. It operates as a humectant by attracting atmospheric water to the skin's outer layer, promoting retention for sustained hydration. Its emollient action lubricates the surface, minimizing roughness and aiding even application. As a skin conditioning agent, it supports suppleness by enhancing moisture balance and texture without residue. Integrated at trace levels, it complements other hydrators to foster a plump, smooth feel across diverse product textures.
