The work aims to summarize the research progress of biodegradable materials in cosmetic packaging and to provide reference for further expanding the application field of biodegradable materials. Through the research and application of biodegradable packaging materials such as polylactic acid, polyhydroxyalkanoate, cellulose and chitosan in cosmetics at home and abroad, the performance characteristics of various materials were analyzed, and the future prospect of biodegradable packaging materials in cosmetics application was put forward. Suitable biodegradable packaging materials should be chosen for different types of cosmetics according to the characteristics of products. The application of bi-odegradable packaging materials in cosmetics should be further studied and promoted. The application of biodegradable materials in cosmetic packaging is one of the future development trends, and the application of nanotechnology is of great significance to the improvement of material properties.
