Cosmetics
companies! Can you say with confidence that a product your customer
buys in bulk today will have the same excellent qualities they expect
from your brand when they open it in six months’ time?If not, you need to start stability testing, pronto.
Stability testing is simply the assessment of the lasting power of a cosmetic, during which samples of it are put under different environmental conditions for a set time period, and its properties analysed. These conditions vary in light, temperature, pressure and humidity levels and are designed to imitate what the product may be subjected to during its lifetime.
