The accelerated stability studies verify that the cosmetic product does not undergo unacceptable changes during its life cycle thanks to the role of barrier that packaging should play. Generally speaking, such changes are due to thermal shock, intense exposure to light and mechanical stress. These changes not only involve the chemical composition of the product, but also its organoleptic bouquet, appearance, texture and its microbiological quality.

As cosmetic and personal care products are conceived from a wide variety of materials and formulations, a standard protocol applicable to all cases cannot be used: regulatory authorities recommend that stability tests are adjusted according to the type of product and the intended use, including the reasonably foreseeable storage conditions. In this area too, Mérieux NutriSciences offers a full set of customizable analysis methods to meet the individual needs of its customers, evaluated on a case-by-case basis.
