The main purpose of cosmetic compatibility testing is to ensure that its intended physical, chemical and microbiological properties and other harmful changes in safety and functionality will not occur during handling, transportation and storage under appropriate conditions, thereby safeguarding the health and safety of consumers.
About cosmetic compatibility testing
Compatibility testing for cosmetic product and packaging quality inspection includes adsorbing product ingredients into the container and then corroding, leaching, and the effectiveness of the container in protecting the contents from atmospheric oxygen and or water vapor. If the product will be sold in several different packaging types, it is advised to research each packaging type. Mechanical shock testing is another additional assessment that is often used to check whether movement during shipping can damage cosmetic products and their packaging.
3) Crazing phenomenon
5) Air bubbles
Is it possible to predict the incompatibility between cosmetic packaging and the contents?
From the incompatibility of cosmetic plastic packaging, we can know about osmosis, adsorption, crazing phenomenon, dissolution, air bubbles and so on. The raw materials used in cosmetic formulations may lead to incompatibility between cosmetic packaging and contents. The relationship between several manifestations of incompatibility and the raw materials used in the content has been marked above, so to a certain extent, the incompatibility between cosmetic packaging and content can be predicted, but ultimately it needs to be tested through the compatibility of the packaging.
