The suitability of Anton Paar's PNR 12 gravity penetrometer in testing products such as cosmetics is detailed in a recently-published Application Flash.
The consistency of cosmetics is important for the product packing, and especially for quality and the product handling.
The PNR 12 measures the resistance a material provides against being pierced by a specifically-shaped test body. This allows a rating of the plasticity or consistency of a product. Thanks to its easy handling and convertibility, the PNR 12 has gained a
wide scope of applications. It is suitable for hard products such as compact powder or soap as well as for creamy products including toothpaste and hair styling gel.
Anton Paar have various test kits available for different cosmetic products. The choice of the accessories depends on the consistency and conductivity of the sample.
