Plastic and glass are the most common packaging materials for cosmetics. We often use these two packaging materials for cosmetics, such as make-up water, emulsion, makeup remover, etc.
The material of Louda Street - plastic, with a proportion of up to 80%
Advantages: high variability, all sizes, shapes, colors, transparent and opaque. Light weight, easy delivery, good printability, recyclable, etc.
Disadvantages: not heat-resistant, light barrier is not enough, solvent resistance is not good (especially grease). Therefore, the first bottleneck of plastic containers is that they cannot be sterilized by high temperature steam, washed with water, or sterilized by light. In addition, considering the stability of the contents, some maintenance items are not suitable for packing in plastic containers.
The most stable and reassuring material - glass, with the proportion of 8%
Advantages: heat resistance, light resistance, solvent resistance, absolutely win. The darker the color, the better the preservation of antioxidant, anti-aging and whitening products, because these ingredients are highly active and easily affected by light. So unless it's poor quality glass, the most suitable home for maintenance products is the glass container.
Disadvantages: apart from being easy to break and refusing to be a toy for children, I can't think of any disadvantages. Of course, if you know it's made of glass, it will never be placed in a position where it's easy to be knocked down.
