Products Usage
Phenylbenzimidazole Sulfonic Acid is a type of UVB sunscreen that also absorbs a small fraction of UVA wavelengths. It is a water-soluble chemical sunscreen. It is often used in combination with other ingredients, such as avobenzone, titanium dioxide, zinc oxide, or celadin. Its protection and quality from sunlight does not decrease over time, so it can somewhat mitigate the breakdown of other UVB isolators in sunscreen.
Phenylbenzimidazole Sulfonic Acid also can convert ingested ultraviolet radiation into less harmful infrared radiation and heat. The texture is clean and not greasy. This product has good storage and transportation stability, It is non-flammable and non-explosive, non-toxic and harmless.
