Cosmetics
Cosmetic
In the cosmetic industry, high viscous dispersions play an important role. These systems are very difficult to characterize with standardized techniques. The shelf-life of cosmetics can be studied with multiple light scattering. Furthermore, particle size and shape play an important role in the application of the products and their classification.
Several Methods for cosmetic products
| ANALYSIS METHOD | PARAMETER | MEASURING INSTRUMENT |
|---|---|---|
| Multiple light scattering | Stability of dispersions | Contract analysis |
| Laser diffraction (wet or dry) | Particle size of powder | Bettersizer S3 series Bettersizer 2600 Bettersizer ST |
| Image analysis | Particle shape | BeVision D2 Bettersizer S3 Plus |
| DLS – dynamic light scattering (Photon correlation) | Particle size in nanometer ranges | BeNano series |
| Acoustic spectrometry | Particle size in micrometer and nanometer ranges in concentrated dispersions | DT-1202 DT-100 |
| Electro acoustics | Zeta potential | DT-1202 DT-310 DT-300 |
