Application PNR 12: Consistency of Cosmetics

The Penetrometer PNR 12 is suitable for consistency determinations in the cosmetic industry. Various test kits are available for different cosmetic products. The choice of the accessories depends on the consistency and conductivity of the sample.

High Efficiency Due to Flexibility

The PNR 12 is a gravity penetrometer and 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.

Due to its easy handling and convertibility the PNR 12 has gained a wide scope of applications. It is suitable for hard products like compact powder or soap as well as for creamy products like toothpaste and hair styling gel.

Why is consistency measurement so essential?

To achieve a constantly high quality it is essential to check the product parameters. The measured penetration values will not only help to assure a constant quality.

The consistency of a product will allow conclusions like:

  • Is toothpaste soft enough to be squeezed out of a tube?
  • How is the spreading behavior of lotion, cream or lipstick?
    Is it thick enough to stay on the skin surface or does it get absorbed quickly?
  • How fast does soap dissolve or gets mushy?
  • Is a lipstick flexible enough or will it break easy?
