What is "Disodium Phenyl Dibenzimidazole Tetrasulfonate"?

Disodium Phenyl Dibenzimidazole Tetrasulfonate, also known as Neo Heliopan AP or Bisdisulizole Disodium, is a chemical sunscreen filter. It is used in the composition of sun care products. According to the rules applied in Europe, the maximum permitted concentration of this active ingredient in a product is 10%. This molecule protects the skin against UVA II rays and has an absorbance peak of 335 nm.

Unlike other sun filters, Disodium Phenyl Dibenzimidazole Tetrasulfonate is not an oil, but a water-soluble organic ingredient. As such, it allows for the creation of less greasy sunscreens. This active ingredient also stands out due to its low level of skin penetration, which is quite reassuring compared to other filters.

What is the purpose of "Disodium Phenyl Dibenzimidazole Tetrasulfonate"?

The Disodium Phenyl Dibenzimidazole Tetrasulfonate is safe and exhibits the following properties:

  • It absorbs UV rays so that sunlight does not harm either the skincare product or its active ingredients;

  • It filters UV rays to protect the skin and hair from the effects of the sun's rays;

  • It acts as a stabilising agent, meaning it is incorporated into the composition of a skincare product to enhance the ingredients and/or promote the stability of the formula;

  • It promotes the shelf life of the skincare product.

"Disodium Phenyl Dibenzimidazole Tetrasulfonate" is primarily used in adult sun care products. You can find this ingredient in the following treatments:

  • Adult sun lotions and creams;

  • Thermal protection sprays for hair;
