How to take the better airless tube

Lip gloss cosmetic tube packaging
There is no doubt that the primary function of cosmetic Lip gloss tube is to protect the contents. The components of cosmetics are added with substances required for the growth and reproduction of microorganisms, such as glycerin and proteins. After the cosmetics are contaminated by microorganisms, they become odor, deterioration, and mildew. The quality of the product is reduced, and moisture and oxygen are factors that affect the growth of microorganisms. . Most cosmetic products contain oils and oils. The unsaturated bonds in the oils are easily oxidized and cause deterioration (rancidity). This oxidation is a chain reaction. As long as a small part of the oxidation begins, it will cause the complete deterioration of the oil and produce Peroxides, acids, aldehydes and other substances that are irritating to the skin and give off rancid odors. Oxygen is the most important external cause of rancidity. Without oxygen, it will not oxidize and cause rancidity. The increase of moisture will also cause the hydrolysis of oil and grease and accelerate the auto-oxidation reaction. Moreover, moisture will provide living environment for microorganisms and reduce The antioxidant activity of certain antioxidants. The preservation of aromatic gas is the focus of cosmetic packaging. For some cosmetics, the aromatic gas itself is the real “product”. If the aromatic gas is lost, the “product” actually sold will disappear. Therefore, for cosmetics, the prevention of odor loss is of great significance.

    Visible, anti-corrosion, anti-oxidation and to prevent the loss of odor is the focus of cosmetics preservation, cosmetics packaging need to perform the following tests: the speed of gas penetration of packaging materials, gas content inside the packaging, and the packaging is intact, that is, packaging material barrier properties, packaging The analysis of the headspace inside the object and the tightness of the package.
