Science
Mechanism of Action
This ingredient functions principally as a fragrance enhancer, providing a pleasant aroma and acting as a fixative to prolong scent longevity. It also exhibits antimicrobial activity, supporting product integrity, and serves as a UV absorber, offering secondary protection against solar radiation. The molecule readily hydrolyzes into isopropanol and cinnamic acid, with the latter component known for its intrinsic UV-absorbing, filtering, and antioxidant properties.
