Product testing is a very common step that many brands participate in prior to the launch of their product. There are multiple kinds of tests including efficiency tests, shelf life tests and tests to measure customer satisfaction levels.
Some brands also conduct tests to ensure that their products are safe for customers to use. It’s been a common practice to conduct these tests on animals (without taking into account what happens to the animals). By turning a blind eye to what happens to animals and aquatic life, this is one way brands participate in animal cruelty.
