BASF Sunscreen Simulator 4.0: Now with even more functionalities

  • The digital tool that supports the development of sunscreens is now even more comprehensive, with the integration of a cockpit functionality
  • Integration of EcoSun Pass® criteria for direct assessment of environmental impact of selected UV filter combinations
  • Evaluation of the interaction of UV filters and emollients

BASF’s Care Creations® has further refined the functionality and scope of its Sunscreen Simulator. The latest relaunch of the virtual laboratory now provides formulators and manufacturers with even more options for digitally defining the UV protection of a sun protection product. Sunscreen Simulator 4.0 offers an updated, customizable user interface. The new cockpit functionality guides users through the simulator and expands options for creating and managing projects and personal data. Access to helpful scientific support has also been integrated into the cockpit.

"The integration of the EcoSun Pass® is a tremendous step forward for formulators. In addition to UV performance, they can now also directly check the environmental impact of the selected UV filter systems," explains Dr. Myriam Sohn from the Global Technical Center Sun Care.

The BASF Sunscreen Simulator serves as a recognized benchmark in the industry for determining the sun protection factor (SPF). In addition to the known performance parameters (SPF, UVA protection, photostability), it is now also possible to perform calculations to protect against blue light irradiation and the generation of free radicals.

The Solubilizer Simulator is also entirely new: As part of the Sunscreen Simulator it evaluates the efficacy of the combination of UV filters and emollients and provides information about the naturalness (as defined by ISO16128) of the emollients.
