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) out-performs existing stabilizers, which simply absorb UV-light, company executives said.
ESQ quenches the excited state of molecules when exposed to light and degradation caused by UV radiation. The technology 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 company executives.
