As a formulator, there are three types of testing that you may be called on to do. These include quality control testing, consumer testing and claims testing. Gaining an understanding of the uses and challenges of each type of testing will make you a more well-rounded cosmetic chemist.
QUALITY CONTROL TESTING
This type of testing is done to ensure that the product you and your company produce is safe, effective and consistent. The idea is that if you set up a range of specifications for a formula and each batch falls within those specifications, you can assume that the product will be of suitable quality.
The most simple types of quality control tests are characteristics like color, appearance and odor. These are normally tested by a trained individual comparing the current product to a known standard. While these tests are subjective, people can get reliably good at noticing subtle differences.
