AHRD

Testing & Analysis

It is a must to conduct microbiological, accelerated stability and preservative efficacy testing of each product before proceeding to its manufacture and this is exactly what formulation experts deal with.

We provide physical and chemical tests in our laboratories. Visual appearance, odour, pH, density and viscosity is tested on all our QA samples randomly selected from production lines.

Several other tests are offered such as stability testing, preservative efficacy testing and microbiological tests. These are all available from independently operated laboratories.

There are a number of tests that can be conducted to mitigate the risk of formulation failure. Whilst formulating, our formulation chemists conduct preservative efficacy tests and a stability test. To briefly explain a preservative efficacy test ensures that the preservative chosen for the product is effective guarding against bacteria, mould and fungi. A stability tests is a series of tests in the final chosen packaging. The AHRD laboratory also coordinate with our packaging suppliers when conducting the stability test. Whilst these tests are an additional cost, they are usually a one-off cost unless packaging or formulations change.
