Why on cosmetics oxygen hose resistance performance testing?

Why on cosmetics oxygen hose resistance performance testing? Cosmetics packaging on the market at present is multifarious, only plastic material is plastic bottles, plastic boxes, plastic bags, plastic hose, etc. In recent years, with the increasingly common cosmetics, cosmetics packaging plastic hose with the raw material used to rapid development, as well as advantages of less, low cost and is now the mainstream of the cosmetic packing market, mainly used in skin cleaning products, cosmetics and beauty salon products and so on. At present, the commonly used in cosmetics packaging plastic hose is mainly including lu: su composite hose, all plastic composite hose and plastic extrusion hose, can meet the various needs of cosmetics packaging. No doubt, the prime function of cosmetics packaging is to protect the contents. The main composition of cosmetics is fat, water-soluble polymer, surfactant, etc. As is known to all, such as glycerin, protein is the material basis for the microbial growth and reproduction, and oxygen and water are the influencing factors of microbial growth; Oil in the unsaturated bond very easy oxidation and rancidity deterioration caused by, and produced oxide, acid, aldehyde, etc excitant material, and gives off rancidity odor. Thus the oxygen is the most important factor of cosmetics metamorphic. Cosmetics hoses need has excellent gas barrier performance, can effectively prevent the infiltration of oxygen and peculiar smell gas, at the same time prevent the content fragrance and effective ingredients. The standards 'GB/T 29336 - In the $2012 cosmetics with extrusion multilayer composite hoses 'oxygen through the amount specified hose test according to the GB/T1038 plastic film and thin gas permeability test method for differential pressure method' regulation, multilayer pipe oxygen through the amount shall not exceed 10 / cm3 ( m2·24h·0. 1MPa) 。 Can be seen that this standard is just on the sheet of oxygen permeability testing regulation, the hose is made after the whole pipe body oxygen permeability is not that clear. Is that there is no need for detection, the answer is no. For cosmetic packing sealing performance of the whole and the tube body oxygen through directly affects the amount of the storage life of cosmetics and the change of the original nature, is related to enterprises must pay attention to and control index. Released on December 31, 2014 in our country, on March 2, 2015 implementation of the standard GB/T 31354 - 2014 packaging and container oxygen permeability test method coulometer test, this paper introduces the drying was determined by coulometer sensor package oxygen transmittance of standard test method. Brief introduction is as follows: first to test the tube with sealant fixed shelf fixed to the experiment, placed after a certain period of time, will be fixed to the sealed sample detection devices. Tube body internally with nitrogen flow slowly purging air, surface of tube in vitro in a known concentration of oxygen environment, namely 20. 8% oxygen content of indoor environment or 100% of the oxygen content in environment. Oxygen through the pipe into the nitrogen carrier gas, and as the nitrogen load flow is carried to the kulun power sensor. How much after oxygen sensor will produce current, current and per unit time are carried to the power sensor is directly proportional to the amount of oxygen. Which can be concluded that the whole pipe body oxygen transmittance, which can better determine the shelf life of product. Direct contact with the human body skin cosmetics, its quality will directly affect the health of human body. In order to ensure product quality and ensure the service life, ensure that the product of the second life, the tube sheet and the forming of tube body oxygen permeability testing is very important.
