Formulation
Stability
This ingredient exhibits sensitivity to light and can undergo oxidation and polymerization when exposed to air. It is frequently supplied with stabilizers, such as 4-tert-butylpyrocatechol (TBC), to mitigate degradation. Optimal storage conditions involve tightly sealed containers in a cool, dry environment, shielded from heat and light.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) has referenced P,ALPHA-DIMETHYLSTYRENE in broader assessments of citrus-derived ingredients, but a dedicated, standalone safety review for its direct cosmetic skin application is currently absent. While it is approved for food applications by the FDA and JECFA (FEMA number 3144), it is formally classified as an irritant to the eyes, respiratory system, and skin.
