Avobenzone, Butyl Methoxydibenzoylmethane

Product Paramete

Application

(1) LGB® ABZ is a very effective UVA I absorber for a wide range of applications, maximum absorption is at 357nm with a specific extinction of about 1100 and it has additional absorbing properties in the UVA II spectrum

(2) LGB® ABZ is an oil soluble, crystalline powder with a slight aromatic odor. Adequate solubility in the formulation must be ensured in order to avoid recrystallization of the Neo LGB® ABZ. The UV filters

(3) LGB® ABZ should be used in association with effective UVB absorbers to achieve formulations with broad-spectrum protection

(4) LGB® ABZ is a safe and effective UVB absorber. Safety andefficacy studies are available on request

LGB® ABZ can be used for the formulation of protective hair-care, medicated skin-care and protective skin-tone preparations. It can be used to quench phototoxic skin reactions initiated by weak phototoxic materials. It is incompatible with formaldehyde, formaldehyde donor preservatives and heavy metals (pink-orange colour with iron). A sequestering agent is recommended. Formulations with PABA and its esters develop a yellow colour. Can form complexes with aluminium above pH 7, with free aluminium resulting from the coating of some grades of microfine pigments. LGB® ABZ is properly dissolved, in order to avoid the formation of crystals. To avoid the formation of complexes of LGB® ABZ with metals, it is recommended to add 0.05–0.1% of disodium EDTA.
