The Formula
Formulation
Stability
Uracil has a pKa of 9.45, with solubility in PBS at pH 7.2 of approximately 8 mg/mL. Optimal adsorption was noted at pH 4, with general cosmetic formulations typically targeting pH 4.5-6.5.
Conflicts
- Uracil-4-carboxylic acid, a derivative, struggles with water solubility at higher concentrations, potentially requiring coupling agents. General pH imbalances or ingredient incompatibilities may also pose formulation challenges.
Safety
Safety Profile
While generally considered safe for topical use, Uracil may cause irritation or redness in some individuals. Pregnancy and breastfeeding safety data is insufficient; consultation with a healthcare professional is advised.
