Steps of Product Development and Testing

Number of steps that all come together in the quality finished product.


The first important thing is using quality ingredients that have been tested and certified by the supplier.


During product development a range of tests has to be done on the formulation during its development long before it goes to market. There are two important types of tests that must be done on the formulation before it can be accepted for selling to consumers:

Preservative test

Products that are water based can support the growth of bacteria and must be preserved for safety.

Once a formulation is done it is important to send it to a preservative test.

The product is challenged with a variety of bacteria and monitored for a months. We check if the bacteria grow or die-off over this time.

If a product is well preserved it will prevent any bacterial growth in the product.

A product with a poor preservative profile could grow bacteria and not only spoil the product but could cause infections as well.

Stability Tests

Stability tests are designed to determine how stable the formulation is and also to assign a use by date.

The product is stored for up to months and we monitor if it changes colour or odour or viscosity and pH as well as other characteristics.

If a product is not stable and starts to break down it could cause allergies and in some cases result in bacterial growth and it can cause infections.

Product stability is a crucial part of product quality.


It is important to ensure the most hygienic manufacturing possible, backed up by quality control and by finished product testing.

The most important part of this is to ensure that every batch manufactured is free of bacteria and meets the quality tests for that formulation.

Cosmetics can easily become contaminated with bacteria because of poor quality ingredients, unhygienic manufacturing and the use of poor quality water.

Batch testing is a crucial control to ensure bacterial safety of cosmetics.


The use of quality ingredients, products are carefully developed and formulated and goes through the process of types of preservative tests, stability tests and individual batch testing for customers to get the safest products possible.
