Viscosity measurements in our laboratory showed the effect of biopolymer dosage in pigment water-based slurries.
Pigment slurry dispersion
Pigments with several different solids contents used in colour cosmetics formulations were prepared and mixed with an increasing dosage of Borregaard biopolymer product.
Key takeaways:
- Viscosity is reduced at an optimum dosage level
- Allows for better milling
- Achieves smaller particle size
