Ciba Specialty Chemicals developed a new class of stabilizer technology that is said to increase the shelf life of cosmetic and household products. Excited State Quencher technology (ESQ) outperforms existing stabilizers, which simply absorb UV-light, company executives said.
ESQ quenches the excited state of molecules when exposed to light. The effect applies to degradation caused by UV-radiation and shuts down degradation pathways.
In comparative studies, ESQ was more effective than current technology as a stand-alone stabilizer and showed great boosting effects when combined with UV absorbers, according to Ciba executives.
