| Résumé : |
Varying legislations and guidelines regarding UV filters and the levels of UVA protection required in different regions has been a challenges in different regions has been a challenge for sunscreen formulators in recent years. Confidence in the use of ZnO in products claiming UV protection has increased stemming from the change in the SCCS opinion and has provided formulators with more options when creating a broad spectrumUV protection product.
Improved knowledge about the relationship between TiO2 and ZnO allow the formulator to have a better understanding of how to formulate SPF products with broad spectrum protection allowing them more time to focus on creating aesthetics suitable for everyday use. The results from a comparative study with varying ratios make it easier to determine the levels of TiO2 and ZnO to use in order to obtain the desired SPF, critical wavelength and UVAPF saving valuable time and enabling more efficient development of formulations. |
