PARSOL® SLX An award-winning, multi-talented UVB filter for sun, skin and hair care

dsm-firmenich continues to redefine the standards of elevated UV protection—this time with the latest scientifically proven benefits of PARSOL® SLX. When combined with pigmentary UV filters, PARSOL® SLX can enhance sunscreen performance by up to 50%, all while maintaining a superior sensorial experience on the skin. This innovation comes at a time when consumers are increasingly seeking products with lower chemical content and elevated textures - making this a timely and impactful solution for the sun care industry. PARSOL® SLX also enhances hair color protection and provides powerful fiber UV Defense, leaving hair soft and smooth. As a House of Science, it is our commitment to do ongoing research on our products and are beyond excited to share the news with our customers and the public. Award-winning PARSOL® SLX is the first film-forming polymeric UVB filter, which combines science-backed superior defense with an exceptional sensorial experience, with no heaviness, just elevated performance and certified microbiome-friendliness.

In sun care, this innovative solution delivers high protection with a barely-there feel. Unlike traditional sun protection that often demands heavy formulations to ensure effective UV defense—leaving the skin greasy and uncomfortable— PARSOL® SLX enhances SPF performance by forming an invisible, uniform shield. It is the ideal partner for daily skincare routines on preventing premature skin aging caused by sun exposure, effectively delivering both superior comfort and efficacy.

‘Today’s consumers are increasingly seeking sun protection solutions that minimize chemical load without compromising on performance’ says Tina Vogt, Director Global Marketing Sun Care; ‘with PARSOL® SLX, we’re proud to offer a future-proven UVB filter that meets this demand—delivering high SPF efficacy with a lightweight, elegant skin feel. Its unique polymeric structure allows for reduced ingredient concentration while maintaining superior protection, making it a smart and sensorially pleasing choice for modern sun care formulations.’

‘In Hair Care, PARSOL® SLX protects hair from photodamage, prevents color fading, and provides a lightweight, luxurious feel.’ says Melanie Waeckel, Global Sr. Marketing Manager Hair Care; ‘Instrumental tests demonstrate up to 32% color retention of red permanent hair. Leveraging the smart film-forming technology, it delivers UV performance, leaving hair soft and smooth.’

Engineered with a large molecular structure PARSOL® SLX stands apart from smaller UV filters with its polymeric design delivering enhanced film formation, broad compatibility, and efficiency.
