Will the plastic empty cream jar react or degrade with the product inside?

The plastic empty cream jar is unlikely to react or degrade with the products in it under normal circumstances, especially if the can is made of materials suitable for storing cosmetics and skin care products. The following are some considerations about the compatibility of plastic empty cream jars with products:
Material selection: Commonly used plastic materials such as polyethylene (PE), polypropylene (PP), and polystyrene (PS) have good chemical stability and usually do not react with most cosmetics and skincare products. These materials are widely used in cosmetic packaging because they can resist corrosion from various ingredients.
Food grade and cosmetic grade plastics: Plastic cans used for packaging cosmetics are usually food grade or cosmetic grade, which means they are tested and certified to ensure that they do not release harmful substances or react chemically with internal products.
Anti UV materials: Some plastic cans may have added anti UV (UV) stabilizers to prevent degradation caused by UV rays in sunlight. This is particularly important for products containing photosensitive components, as ultraviolet radiation may cause certain chemical components to degrade or fail.
Inner lining or coating: Some high-end plastic cans may have special inner lining or coating to provide additional protection, prevent direct contact between the can body and the product, and thus avoid potential reactions.
Testing and verification: During the production process, manufacturers usually conduct compatibility testing on packaging materials to ensure that plastic cans are compatible with specific products. This includes long-term storage testing to check whether the tank and product will experience any adverse reactions under different conditions.
However, some specific active ingredients or chemicals may react with plastics. Therefore, when selecting plastic empty cream jars, it is necessary to consider the compatibility of product ingredients and packaging materials. If you have any doubts, it is best to consult the packaging supplier or conduct compatibility testing to ensure safety and stability.
In general, high-quality plastic empty cream jars will not react or degrade with internal products under normal conditions of use, ensuring the safety and effectiveness of the products.
