This easy-to-use UV protection in the form of a stable, homogeneous dispersion avoids the usual problems that occur when processing physical light protection filters:
 
- The user is not exposed to dust during application.
- The user is spared the time-consuming preparation of the pre-dispersion; special equipment for the preparation of the pre-dispersion is not required.
- the uniform, fine distribution of the titanium dioxide pigments ensures optimum UV efficiency
- the presence of suitable dispersing agents avoids instabilities such as clumping or settling of the pigments
- the liquid dispersion can be easily incorporated into the formulation
 
The average particle size of titanium dioxide micro pigments is in the range of 170 - 185 nm. Since the particle size distribution is very narrow, these are not nanoparticles. Even "whitening" occurs only moderately, as only a few particles exceed the critical size of 200 nm for this. Due to their structure (rutile), size, and spherical shape, the micro pigments used not only show the high UVB protection known for titanium dioxide, but also an unusually high UVA protection for this pigment. Since the titanium dioxide pigments are photostable, i.e. they do not decompose or oxidize under the influence of UV light like chemical filters, the UV protection is maintained as long as the light protection filters remain on the skin. In addition, thanks to their excellent coating, the pigments show very low photocatalytic activity. The sunscreen dispersion combines very good sun protection with very good skin compatibility - formulations with this pre-dispersion leave the skin feeling silky and are especially recommended for sensitive skin.
 
The sun protection dispersion XT 40 is suitable for natural cosmetics.
Processing: 
Stir into the water phase heated to 70 - 80 °C; important: keep the temperature at 70 - 80 °C; then disperse at high speed with the oil phase, which is also at 70 - 80 °C. In the case of an oil-in-water emulsion (here the water is the continuous phase!), the water-soluble sunscreen dispersion can also be stirred into the emulsion after emulsification - at high speed if necessary.
 
Tip:
This sunscreen dispersion is compatible with microfine zinc oxide (additional care + even better UVA protection). To increase the SPF, you can also combine the oil-soluble and water-soluble sunscreen dispersion in one formulation.
