Key Functions: Cosmetics & Personal Care, Industrial / Manufacturing

Phenolic benzotriazoles are extensively used in plastics, coatings, and other materials as light stabilizers. These products function by competitive absorption of the damaging UV radiation in sunlight. Compared to the substrates they protect, phenolic benzotriazoles are characterized by a much stronger UV absorbance, outstanding photostability (owing to the rapid deactivation of excited states via radiation-less processes), and high chemical stability. In this way they are able to provide long-term protection for many different types of plastics and coatings against the effects of sunlight.
