Abstract：In order to further use green cosmetic packaging materials and reduce carbon emissions, relevant tests were carried out for the application of bio-based low-density polyethylene (Bio-PE) instead of petroleum-based low-density polyethylene (petroleum-based PE) in cosmetic packaging materials. Firstly, the biological origin of Bio-PE was verified and the physical property parameters of Bio-PE and petroleum-based PE were compared. The results show that the physical property parameters of Bio-PE and petroleum-based PE are similar. Therefore, the process parameters suitable for petroleum-based PE processing are also suitable for Bio-PE. Furthermore, Bio-PE and petroleum-based PE were processed into disposable cosmetic packaging materials by three-in-one aseptic filling equipment integrating blowing, filling and sealing. The performances of the two disposable cosmetic packaging materials were compared, including water vapor transmittance, oxygen transmittance and total migration under three different simulated environments. The results indicate that Bio-PE and petroleum-based PE disposable cosmetic packaging materials have similar barrier properties and total migration under three different simulated environments on the whole. Then, according to the biological evaluation method of medical devices, Bio-PE was tested for skin irritation and skin sensitization. The results show that Bio-PE don' t cause skin irritation and sensitization. Finally, the compatibility of Bio-PE disposable cosmetic packaging materials and cosmetic interior material was investigated, it is proved that Bio-PE can not affect the appearance, pH and viscosity of cosmetic interior material, and the relative productivity of cells of the essence soaked in Bio-PE can not increase compared with that of petroleum-based PE. Therefore, Bio-PE can be used in cosmetic packaging materials instead of petroleum-based PE.
