Science
Mechanism of Action
This ingredient operates at a cellular level by supplying uridine, a crucial component for the biosynthesis of DNA and RNA. It is noted to specifically bolster nucleotide excision repair, a key process for correcting DNA damage such as pyrimidine dimers induced by UV radiation. Furthermore, Disodium Uridine Phosphate has demonstrated capacity to mitigate oxidative stress and inflammation by inhibiting the MAPK and NF-kB signaling pathways. Its derivatives are also implicated in enhancing the endogenous production of vital skin components like hyaluronic acid, glycosaminoglycans, and collagen, thereby promoting tissue regeneration.

Stability
Stock solutions are recommended for sealed storage at -80°C for up to 6 months, or -20°C for 1 month, away from moisture. The substance is considered stable under normal ambient and anticipated storage conditions when kept in a dry, cool place.
Conflicts
- strong oxidizing agents (e.g., nitrates, oxidizing acids, chlorine bleaches) due to potential for ignition
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has not conducted a specific review for Disodium Uridine Phosphate, though simple salts of phosphoric acid have been reviewed. The substance is generally classified as non-hazardous in safety data sheets, with 'Nil Reported' for toxicity and irritation in some studies. It does not meet GHS hazard criteria for 94.1% of all reports. As a cosmetic ingredient, it is permitted for use within products subject to FDA regulations, though it lacks individual FDA approval.
