MBBT Aqua Dispersion — Active Ingredient CAS 103597-45-1 | UV Filter Supplier
CAS 103597-45-1
Broad-spectrum UV-A and UV-B filter dispersion designed for the water phase, with strong long UV-A I absorption.
Overview
MBBT Aqua Dispersion
MBBT Aqua Dispersion is a ready-to-handle, water-phase dispersion of the MBBT active, supplied by Sigmak under product code SIG-UV-018. CAS 103597-45-1 identifies the MBBT active ingredient itself, not a separate registration number for the formulated dispersion.
Same bis-benzotriazole active as powder-form MBBT, supplied as a stabilized aqueous dispersion for direct water-phase addition rather than melt or powder incorporation.
