Laboratory work on mineral pigment slurries

Pigments with several different commonly used solids contents in sun cream formulations were prepared and mixed with increasing dosage of Borregaard biopolymer product.

We measured the resulting viscosities in our laboratory.

Key takeaways:

  • Viscosity reduced at the optimum dosage level
  • Allows for better milling
  • Achieves smaller particle size
