Characteristics and raw material requirements of cosmetic glass bottles

The oral liquid glass bottle is mainly made of colorless glass tube and amber glass tube. The side view of the colorless glass bottle is slightly blue, green and yellow. The glass bottle produced by this kind of glass has high fire resistance and internal The stress is large, it will not be easily damaged, the quality is guaranteed, and it will not be easily damaged, and it can be customized according to customer requirements. However, when we use it in the later period, we should first fill the oral liquid glass bottles before filling, pick them, wash them with purified water a second time, then wash them with distilled water, and then disinfect them at high temperature. After ensuring that the oral liquid glass bottle itself does not have quality problems, it is filled. The environment for the liquid medicine filling is also particularly important. Filling, picking, cleaning, high temperature disinfection and then packing into the pallet are required in the purification workshop. During high temperature disinfection, we should also pay attention to prevent extreme cold and extreme heat, and avoid blasting the glass bottle of oral liquid from the bottom. The filling of the oral liquid glass bottle should be filled within the allowable range. Overfilling will cause the bottom to fall during the later high temperature and high pressure disinfection, resulting in the loss of liquid medicine. There are two kinds of oral liquid glass bottles on the domestic market, one is soda lime glass, and the other is low borosilicate glass. Now with the continuous development of domestic industry, the containers used to contain medicines, such as water injections and freeze-dried powders, are all shifting to neutral borosilicate glass. Why are the oral liquid bottles still made of soda-lime glass and low borosilicate glass? The material is hovering. Doesn’t it develop like neutral borosilicate like other drugs? This is mainly because the oral liquid is not too corrosive. The oral liquid bottle made of soda lime glass and low borosilicate glass can meet the requirements of oral liquid. However, foreign neutral borosilicate glass only requires water resistance but not alkali resistance. If it is used for oral liquid, it will cause a lot of waste, which is not allowed by domestic conditions.
