Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
The water solubility of the active ingredient of Mexoryl SBO was estimated by a model calculation using the partition coefficient of the test item. Its water solubility at 25 °C was estimated to be 548.3 mg/L for the active ingredient. The present formulation of Mexoryl SBO is based on water. The content of the active ingredient is higher than the estimated water solubility as stated above. There might be different reasons for this finding: the water solubility was calculated based on the partition coefficient and therefore on the neutral form of the active ingredient. However, the active ingredient mainly exists in its sodium form, and therefore the water solubility is expected to be higher. In addition the solubilizer dipropylene glycol is used in the formulation and can increase the solubility of the neutral form. As the formulation of Mexoryl SBO based on water, it is therefore miscible with water at any ratio.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
