Hi, How are you?
Today, for those of you who want to learn how to improve the UV protection of your sunscreen products, we would like to introduce the advantage of using mineral filter dispersions.
Using TiO2 and ZnO dispersions is almost always better than using TiO2 and ZnO powders. When we compare ZnO powder and ZnO dispersion individually with the same ZnO content, you can obtain the higher SPF and PA values when using ZnO dispersions.
This result can be explained using a Microscopic image. ZnO is not aggregated when using the dispersion type, thus it has better UV performance.
You can choose a suitable product in our dispersion product range depending on your formulation.
If you have any inquiries, feel free to contact us.
