Stability
Laccaic Acid exhibits pH-dependent color changes, appearing orange-yellow below pH 4.5 and purplish between pH 4.5 and 5.5. Fading begins above pH 5.5 and becomes significant past pH 12. It demonstrates stability to light and heat under acidic conditions. It is slightly soluble in water (0.0335% at 20°C), ethanol (0.916% in 95% ethanol), and propylene glycol, and can be extracted with deionized water at 60°C. It is also soluble in lye.
Safety
Safety Profile
Laccaic Acid is explicitly classified as 'Forbidden in Europe' with 'high use restrictions' under the EU Cosmetics Directive, deemed 'Banned or found unsafe for use in cosmetics'. While used as a color additive in foods and some cosmetics in the United States, it is not widely reported or utilized as a functional cosmetic ingredient. The CIR has not reviewed its safety as a cosmetic ingredient.

Verdict
Due to its regulatory status as 'Forbidden in Europe' for cosmetic use and the lack of robust clinical evidence for functional skin benefits, Laccaic Acid is not recommended for precision skincare formulations.
