About
A benzylidene indolinone compound — likely a synthetic melanin precursor or pigmentation agent. Used in some skincare formulas for its UV-absorbing and color-stabilizing properties.
3-(2,4,6-Trimethoxybenzylidene)indolin-2-one is a benzylidene derivative of indolin-2-one. The benzylidene moiety confers visible light absorption, making it useful as a color-imparting agent or UV filter in cosmetic formulations. Its safety profile is not extensively documented in standard toxicological databases, and it is not listed in EU CosIngAnnexes I–III. Limited data suggests low acute toxicity but potential for photoallergy at relevant concentrations.
Skin benefits
- UV-absorbing properties
- May act as a visible light filter protecting against pigmentation
