What Tests Are Needed Before Choosing A Cosmetic Packaging Cream Tube?

As one of the mainstay industries of fast-moving consumer goods, consumers have higher requirements for the safety of cosmetic packaging materials. Therefore, the testing of cosmetic packaging materials is particularly important.

For the entire cosmetics development process, it’s not a wise choice to past the compatibility test of packaging materials, which takes the longest time, because even the best packaging materials cannot be guaranteed to be compatible with the product.

The compatibility normally means the interaction between the packaging material and the content, including chemical compatibility, physical compatibility, and biological compatibility.
