What it is
Disodium Inosinate is the sodium salt of inosine monophosphate, a nucleotide widely known as a savory flavor enhancer in food. In skin care it is used at low concentrations as a conditioning ingredient and is frequently combined with disodium guanylate. Within a sunscreen it functions as a minor supporting additive rather than a core ingredient.
Safety & warnings
Nucleotide salts of this kind are generally well tolerated in cosmetics at the low levels used. They are water soluble and not associated with clogged pores.
Origin & sourcing
Typically produced by fermentation or enzymatic processing of nucleotide sources, then converted to the disodium salt.
