Yes, it is possible to test the compatibility of packaging with your cosmetic or skincare products. Cosmopacks understands the importance of selecting the right materials for packaging to ensure product stability and safety. Our team can provide compatibility testing to ensure that the packaging we provide will not react with your product.   For example, we can test the compatibility of our PET bottles with your specific formulation to ensure that the material will not affect the stability of your product. We also offer a range of safe and stable materials, such as glass and high-density polyethylene (HDPE), which are commonly used for packaging cosmetics and skincare products.
