Fluorescent Brightener 230

Fluorescent Brightener 230 is a synthetic organic compound designed to absorb ultraviolet (UV) radiation. It belongs to a class of ingredients known as optical brighteners, which were originally developed for textiles and paper to enhance their appearance under UV light. In skincare formulations, it functions as a UV absorber rather than a reflective or scattering sunscreen agent.The ingredient works by accepting energy from UV rays and re-emitting it as visible light, effectively converting potentially damaging UV radiation into wavelengths the skin can tolerate more easily. This mechanism…

Fluorescent Brightener 230 absorbs UV photons (light energy) and undergoes an electronic transition to an excited state. Instead of dissipating this energy as heat (which could damage skin cells), the molecule releases it by emitting visible light in the blue-violet spectrum. This process effectively neutralises the harmful potential of UV radiation before it penetrates deeper into the skin.The ingredient is incorporated into the formulation matrix, where it remains distributed throughout the product. Upon application to skin, it creates a protective layer that intercepts UV radiation and c…

If using a product containing Fluorescent Brightener 230 as your primary sun protection, apply generously and evenly to all exposed areas. Allow the product to set for a few minutes before sun exposure. Reapply every two hours or after swimming, sweating or towel drying, as with any sunscreen. For optimal protection, combine with other sun-protective measures such as protective clothing and seeking shade during peak UV hours.

Fluorescent Brightener 230 is approved for use in cosmetics in the EU and other regions. It is generally well-tolerated and rarely causes irritation; however, those with very sensitive skin or known sensitivities to optical brighteners should patch test first.
