avobenzone

According to some studies, "the most effective sunscreens contain avobenzone and titanium dioxide."

Avobenzone has been shown to degrade significantly in light, resulting in less protection over time.

It helps prevent the photodegradation of other sunscreen actives like avobenzone.

Avobenzone has an absorption maximum of 357 nm.

Complexing avobenzone with cyclodextrins may also increase its photostability.

The ingredients known to offer appropriate protection are titanium dioxide, zinc oxide, or avobenzone.

Avobenzone reacts with minerals to form colored complexes.

The stability of avobenzone can also be improved by bemotrizinol, octocrylene and various other photostabilisers.

But avobenzone is recommended as a good UVA filter.

Look for oxybezone, sulisobenzone, avobenzone (Parsol 1789) or ecamsule in the ingredients.

Similar concerns have been expressed for related products including avobenzone, octisalate, octocrylene, homosalate, and octinoxate.

For example, a certain boron complex of sunscreen compound avobenzone exhibits reversible ML.

More interestingly, the emission color of the crystals relies on the molecular packing of the boron avobenzone complex.

This is important because a limitation of Avobenzone is that it can undergo molecular changes that affect its protective properties.

Manufacturers of avobenzone, like DSM recommend to include a chelator to prevent this from happening.

Oxybenzone versus avobenzone?

Other UVA blocking compounds found in sunscreen include zinc oxide and avobenzone.

Some of the sunscreen-approved ingredients that the agency listed were zinc oxide, titanium dioxide, dioxybenzone and avobenzone.

The FDA rules also propose allowing sunscreens to combine avobenzone and other existing ingredients, which could lead to more products, agency officials said.

Avobenzone exists in the ground state as a mixture of the enol and keto forms, favoring the chelated enol.

The makers of Coppertone advise that avobenzone binds iron and can cause staining of clothes washed in iron-rich water.

The company uses a patented Helioplex technology to stabilize two UV blockers, avobenzone and oxybenzone.

Due to its high photostability, derivatives of DBM such as avobenzone, have found applications as sunscreen products.

These contain either micronized zinc oxide or titanium oxide or Parsol 1789 (avobenzone).

Off label uses of Bar Keepers Friend include removing the brown or yellow stains caused by Avobenzone containing sunscreen.
