What it is
Sodium RNA is the sodium salt of ribonucleic acid, a high-molecular-weight biopolymer made of nucleotide units. In cosmetic formulas it functions as a humectant and skin-conditioning agent, binding water and contributing to a smooth, conditioned surface feel. It is used at low levels in serums and sunscreens as part of a conditioning blend.
Safety & warnings
Sodium RNA is a large, water-soluble biopolymer used at low levels and is generally well tolerated as a conditioning agent. It is not considered comedogenic and is not a recognized fragrance allergen.
Origin & sourcing
Sodium RNA is the neutralized sodium salt of ribonucleic acid, a biopolymer typically derived from natural sources such as yeast.
