Hose cosmetics packaging played a role in protection of cosmetics

Hose cosmetics packaging played a role in protection of cosmetics and there is no doubt that the prime function of cosmetics hose is to protect the contents. Cosmetic ingredients added required for microbial growth and reproduction of the material, such as glycerol and protein. However, microbial contamination, cosmetics fetid, metamorphism and moldy. The quality of the products down. Water and oxygen are the factors that affect the growth of microorganisms. Most cosmetics contain grease composition. Oil in the unsaturated bond easy oxidation and cause metamorphism. Moreover, the oxidation is a chain reaction. As long as a small part of the cosmetics to oxidation, it will cause oil completely spoiled. At the same time can produce hydrogen peroxide, acid, aldehyde, etc can irritate the skin material, release the smell of rancid. Oxygen is the main external cause rancidity. Will happen, no oxygen oxidation, lead to rancidity. The increase of water can also cause oil hydrolysis, speed automatic oxidation reaction. In addition, the water will provide living environment for microbes, reduce some antioxidant activity. The preservation of the aromatic gas is the key point of cosmetic packaging. For some cosmetics, fragrance gas itself is the real 'product'. If aromatic gas disappears, the actual sale of 'product' will disappear. Therefore, to prevent the loss of smell is very important for cosmetics. Visible, anti-corrosion, anti-oxidation, prevent loss of smell is the key point of cosmetics to save. The following tests should be performed cosmetic packaging: the speed of the gas permeability of packaging materials, packaging, the gas content in the packaging is intact, that is, the protective performance of packaging materials, the top of the space inside the package gas analysis and tight supply of packaging materials.
