How innovative UV filters are redefining sun protection

Symrise has a long history of innovation in sun protection dating back to the 1930s when the UVB filter PHENYLBENZIMIDAZOLESULFONIC ACID – now known under the brand name Neo Heliopan® Hydro – was developed and launched. This groundbreaking product addressed the harmful effects of UV radiation on human skin. Since then, Symrise has developed a comprehensive portfolio of UV filters, enabling customized sun protection formulations that meet the different needs of consumers.

UV radiation is classified into three types: UVA, UVB and UVC. While UVC is absorbed by the ozone layer, UVA and UVB reach the earth's surface and affect human health. UVA rays are the lower-energy part of UV radiation and can contribute significantly to reddening of the skin and long-term skin damage. UVB rays are the main cause of sunburn and tend to damage the upper layers of the skin. UVB also contributes significantly to the development of skin cancer.

Symrise recently expanded one part of its portfolio with the two modern organic UV absorbers Neo Heliopan® EHT, a highly effective UVB filter and Neo Heliopan® 354, an effective UVA filter. Both are ideal for sunscreens with a high sun protection factor (SPF) and waterproof formulations and offer comprehensive UV protection in various cosmetic applications, from daily skin care to outdoor activities.

To achieve broad-spectrum UV protection, Symrise offers solutions that combine chemical and mineral UV filters. Neo Heliopan® EHT works synergistically with mineral filters such as zinc oxide and titanium dioxide. The UV filters Neo Heliopan® ZnO 40 and Neo Heliopan® ZnO 300 contain zinc oxide and focus on increasing the SPF respectively on improved UVA protection. Additionally, Symrise offers Neo Heliopan® TiO, a titanium dioxide-based filter with broad-spectrum protection. The development here is particularly dynamic, as they can absorb both UVA and UVB radiation. Broad spectrum filters are effective, photostable and suitable for a wide range of cosmetic applications.

For the development of the latter three Neo Heliopan® UV filters Symrise collaborated with Kobo, a US company has specialized in powders and dispersions used in color cosmetic products and inorganic UV filters since 1987. By acquiring a stake in Kobo, Symrise has expanded and modernized its portfolio.

Sustainable sun protection

In response to the growing demand for natural and environmentally friendly sunscreens, Symrise has developed these sunscreen solutions that are suitable for all skin types and offer high skin comfort. The surface treatment of the mineral filters enables faster and cleaner production with less dust generation, resulting in more energy-efficient and sustainable manufacturing processes.

Symrise's commitment to innovation in UV protection drives the development of new solutions that meet evolving legal requirements and consumer needs. With a comprehensive range of UV filters, Symrise enables the production of safe, effective, and sustainable sunscreens and is a leader in protecting the skin from the harmful effects of UV radiation.
