FEATURE AND APPLICATION
*JADEWIN UV 1789(AVOBENZONE) is broad spectrum UV absorber with effective absorbtion in both UVA and UVB region
*JADEWIN UV 1789(AVOBENZONE) is suggested to be used in sunscreen products and formulation of protective hair-care, medicated Skin-Care and also to quench phototoxic skin reactions initiated by weak phototoxic materials.
*JADEWIN UV 1789(AVOBENZONE) is incompatible with formaldehyde,formaldehyde donor preservatives and heavy metals（Pink-Orange Color with Iron）, formulation with PABA and its esters develop a yellow color. It can form complexes with aluminium above PH.7.
So JADEWIN UV 1789(AVOBENZONE) should avoid Iron and Ferric Salts, Heavy metals,Formaldehyde donors, PABA and PABA esters.
