- Recommendations from the website It seems to be posting the wrong details on the usage rate or not? Seen on the technical page like this

Utilization rate: 0.1% - 1%

Recommended utilization rate: 0.5%

hello


The formula that uses Titanium Dioxide Transparent (15nm, Water-Dispersion) doesn't mean that other ingredients in the formula need to be water based as well. and the oil part In the oil part, it can also put other sunscreens that are dispersed. or soluble in oil as well


If you don't want to make an emulsion, you may consider using Preservatives that can dissolve in water, such as Na-Ecamsule (eq. Mexoryl SX) .
