Cosmetic packaging essential oil bottles have a variety of material qualities. The essential oil bottles on the market are generally made of glass, followed by plastics composed of synthetic resins, plasticizers, stabilizers, and colorants.
Essential oil bottles are packaged in plastic containers with a high degree of variability, and all sizes, shapes, colors, transparent and opaque can be done. Essential oil bottle glass material is also a kind of packaging material with a long history. With many packaging materials pouring into the market, essential oil bottle glass still occupies an important position in cosmetic packaging, which is inseparable from its packaging characteristics that other packaging materials cannot replace. Light weight, easy transportation, good printability, recyclability, etc., are the reasons why plastic containers are more selected. However, the shortcomings of plastics are also fatal. They are not heat resistant, insufficient light barrier properties, and poor solvent resistance (especially It is grease). Therefore, the problem of plastic containers is that they cannot be sterilized by high temperature steam, cannot be washed with water, and cannot be sterilized by light. In addition, considering the stability of the contents, products like essential oils are not suitable for packaging in plastic containers.
Essential oil bottle glass material compared with plastic (structure: synthetic resin, plasticizer, stabilizer, colorant), the quality of glass material is superior in heat resistance, light resistance, and solvent resistance. Therefore, unless it is low-quality glass, glass containers are very suitable for essential oil bottles as the storage of plants. The color of the essential oil bottle, due to the extraction of plants in the essential oil, there are many plant ingredients with nutritional value, and these ingredients need to be kept away from light, otherwise the original effect will not be achieved. At this time, the color of the essential oil bottle should be brown, because brown has a better light-shielding effect among all colors. In some cases, avoid using plastic, easily soluble or oil-painted containers for essential oils. When diluting essential oils, you need to use essential oil bottles, glass, stainless steel, or ceramics.
