Phenylbenzimidazole sulfonic acid is often used as a common active ingredient in all sunscreen products. It is very effective when it comes to protecting the skin from the harmful effects of the sun’s UVB rays. In case of UVA protection, it should be kept in mind that the compound is not that efficient as a shield.
To make sure that Phenylbenzimidazole sulfonic acid has the capability to protect an individual from both the UVA and UVB rays of the sun, it needs to be paired with titanium dioxide, avobenzone or a similar compound like zinc oxide.
Ensulizole is soluble in water which means that cosmetic products that have the compound as an active ingredient feels light to the skin post application. When used in the manufacturing of lotions, sunscreens and moisturizers, it is often seen that patrons prefer products containing Phenylbenzimidazole sulfonic acid due to its non-greasy and light finish.
In short, it is one of the best protective compounds for human skin against UV radiation.
