Science
Mechanism of Action
Operating as a potent emollient, Isodecyl Citrate delivers exogenous lipids to the stratum corneum, effectively bridging microscopic gaps within the intercorneocyte matrix. This action fortifies the skin barrier, significantly mitigating transepidermal water loss (TEWL) and thus preventing dryness and flakiness. Its barrier-supporting capabilities also contribute to improved skin elasticity and offer protection against environmental dehydrators.

Formulation
Stability
As an alkyl citrate ester, Isodecyl Citrate is inherently hydrophobic, exhibiting higher solubility in organic liquids rather than water. While a specific optimal pH range for its stability has not been defined, its parent compound, citric acid, possesses buffering capabilities with a pKa of approximately 3.1 for its most acidic carboxylate.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has concluded that Isodecyl Citrate is safe for use in cosmetic applications, specifically at concentrations up to 12%. It is officially recognized by the FDA Global Substance Registration System (GSRS) and has been deemed not to meet GHS hazard criteria by the European Chemicals Agency (ECHA), indicating a low overall risk profile.
