OBSERVATION'S ESQ=Excited State Quencher
TECHNOLOGY Co. s ESQ™ Excited State Quencher technology reduces the potential for degradation reactions by minimizing the lifetime of excited states and inhibiting side reactions of excited state intermediates

Stabilization of clear packaged product formulations by absorption of UV light is a well-known technique with Co. s benzotriazole broadband UV light stabilizers being most powerful.

However, by just the absorption of UV light, not all potential degradation pathways are blocked. Another approach to avoid (UV-) light induced decomposition is the quenching of excited chromophores. Co. s innovative stabilizer, based on Co. s ESQ™ Excited State Quencher technology is now available for home & fabric Care products.



Co. s prodt. reduces the potential for degradation reactions by minimizing the lifetime of excited states and inhibiting side reactions of excited state intermediates. Moreover, combined with Co. s benzotriazole UV light stabilizers it exhibits boosting effects yielding in levels of protection beyond what was previously possible. This combined “boosting” effect allows also for synergistic, low cost stabilization solutions offering protection beyond UV absorption
