On the occasion of in-cosmetics Global (April 8-10, 2025, Amsterdam), Basf has updated its sunscreen simulator, its digital laboratory for the development and optimization of sunscreen product formulations.
A key technical innovation is the ability to select different formulation types, including oil-in-water (O/W), water-in-oil (W/O) or oils, to explore the effect of sunscreen formulation type on performance. "Taking into account the impact of formulation type and viscosity on SPF is a significant step towards more accurate SPF simulation and prediction".said Myriam Sohn, senior researcher at Basf's global technical center for sun care.
Improved calculations
Thanks to this update, customers have access to solubility calculations and evaluations. By connecting the filtration system to specific emollients, they get clear information on the dissolved percentage of each solid UV filter, and can assess the interactions between these ingredients to streamline their formulation development.
Another function helps formulators better understand regulatory requirements. It helps them identify the right UV filters to meet specific market needs by providing SPF and UVA protection ratings for selected regions. In addition, Basf's EcoSun Pass criterion provides information on the environmental compatibility of selected UV filter combinations.
Get inspired" course and project follow-up
Another new feature is the "Get inspired" guided tour, which allows users to browse Basf's solar formulation database and access prototypes tested in-house by the company's global and regional laboratories. An improved user interface facilitates navigation through the tool's functionalities. Sorting functionality with various filtering options, including regions, project status or keywords, enables users to easily track and search for specific projects.
D'lite integration
The sunscreen simulator has benefited from continuous improvements over the past 25 years to increase the accuracy of predictions. With its integration into D'lite, Basf's digital knowledge services platform for the personal care industry, users can leverage the Basf ecosystem to increase efficiency and innovation throughout the formulation development process. Users can now explore the sunscreen market and review consumer products. This enables a more comprehensive understanding of product offerings and market trends. The sunscreen simulator will be accessible to all registered D'lite users.
