Cosmetic aluminum hose environmentally friendly

There is no doubt that the primary function of the cosmetic hose is to protect the contents. The ingredients of cosmetics are added with the substances needed for microbial growth and reproduction, such as glycerin, protein, etc., and cosmetics are contaminated by microorganisms, that is, become smelly, deteriorated and moldy, product quality decline, moisture and oxygen is the factor affecting microbial growth. Most cosmetics contain oil composition, oil in the unsaturated bond is easy oxidation and cause metamorphism (rancidity), and the oxidation is a chain reaction, as long as there is a small part of the oxidation, will cause the completely metamorphism of grease, and produced oxide, acid, aldehyde, etc are irritating to the skin of the material, and gives off rancidity odor. Oxygen is the most important external cause of rancidity. Without oxygen, there will be no oxidation and rancidity will be caused. The increase of water will also cause the hydrolysis of oil and accelerate the automatic oxidation reaction. 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 real 'product' for sale will also disappear. So for cosmetics, preventing smell loss is of great significance.

Visible, anti-corrosion, antioxidant and prevent the smell loss is the key of the cosmetics preserved, the need for cosmetics packaging the following tests: speed of gas permeability of packaging materials, packaging, and gas content in the packing are in good condition, namely the barrier property of packaging materials, packaging top air within the body of analysis and packing sealing.
