Glimpse # 4: on an amarillo compound from avobenzone

“¿Qué será lo que fabricas tú?”
Amarillo by Shakira

Today, lili would like to present lili’s new yellow complexes based on avobenzone.

Avobenzone or butyl methoxy dibenzoylmethane (see Fig 0) is a derivative of 1,3-diketone or β-diketone i.e., compounds which are like “the frame of glasses with antennas” such as lili told you in her post about avobenzone.[i] As a mentioned in that post, avobenzone can induce allergic reactions since avobenzone is absorbed into the body once is used and suffers from instability against solvents, light and more.

Avobenzone is predominantly used as solar filter in the UVA range (e.g. 320-380nm) and it is first chemical UVA filter that was approved by the FDA in 1988.

Metal complexes of β-diketones, e.g. avobenzone (Fig.0), are produced by the mechanochemical reaction of at least one β-diketone and/or at least one polyphenol with at least one metal alkoxide according to Liliana’s pending patents. Lili believes that these new polymeric complexes of avobenzone can overcome the safety issues of avobenzone in the USA regulation which is now under scrutiny with magnifying glasses. Since these new compounds based on avobenzone are bigger in the structure in comparison with the avobenzone alone and can be used as colored hydrophobic coating, probably, these novel compounds will not be able to enter to the blood stream and the risk of damage to humans and to the environment would be decreased.

Please just look at lili’s glimpse # 4 if you want to discover more about it.
