Essential oil glass bottle is a kind of cosmetics packaging we are very familiar with, it is also a lot of color, such as blue, brown, transparent and so on, because there is a step in women’s skin care is to wipe essential oil, its price is very expensive in skin care products, before talking about essential oil glass bottles, first talk about the level of essential oil according to the use classification.
1, edible essential oil, which is also strictly controlled, especially in Europe, the EU law has heavy metals including arsenic, lead, cadmium, mercury content limit management, in addition to pesticide residues is also the scope of control, because the test cost is high, non-edible generally will not be used;

Refined oil bottles can be divided into:

Many essential oil glass bottles are blue, is a special kind of glass, the shelf life of essential oil in this blue glass bottle will be extended for half a year. I heard a businessman say this, and the conclusion is that this sentence is neither right nor wrong, yes, because blue glass is obtained by adding cobalt, and the big characteristic of cobalt is that it is magnetic and retains hardness at a high temperature of 982 degrees Celsius. The oxidation resistance is particularly good, so the blue oil bottle with cobalt can indeed extend the shelf life of the product. No, it is because the blue oil bottle on the general market is not added cobalt, but the bivalent iron is made blue because blue, green than brown glass is easier to ensure that the color is uniform and the color of the finished product is consistent (sometimes with the customer’s preferences and the beauty of the product series, I used to like blue cosmetics packaging, such as: If it is really a blue glass bottle made of cobalt powder, then the wholesale price will not be similar to the brown color.
