Know Your Ingredients: Ensulizole

ensulizole

What it is
Ensulizole, also known as Phenylbenzimidazole Sulfonic Acid, is a whitish beige powder.

What it does
Ensulizole is a sunscreen agent that provides mainly UVB and only minimal UVA protection. That’s why, to offer broad-screen protection, Ensulizole needs to be used in products together with ingredients that protect from UVA rays like Titanium Dioxide, Zinc Oxide, Mexoryl SX, Avobenzone and Tinosorb.
Although there aren’t many studies on the stability of Ensulizole when exposed to sunlight, it doesn’t seem to degrade much and may also partly prevent other sunscreen agents from degradation.
Ensulizole is water-soluble, so it feels light and not greasy on skin.

Side effects
Ensulizole is generally considered to be safe.

    All the scientific terms and chemical properties and characteristics, etc…sort of wake up the scientific mind of mine which has long been sleeping since I stopped working to be a full-time mom. ;)

    I’m glad Vonvon :) I try to write in a scientific language but keeping it simple. But I’m always scared I may confuse some people.
