But some cosmetics for a long time don't use or an improper preservation, even in the warranty period, also can appear some changes, such as nail polish, foundation, scrub on oil, liquid on cosmetics, perfume, cream covered with a layer of color. 。 。 。 。 。 These can all be cosmetics metamorphic signal. Does this mean the cosmetics manufacturer before and after the shelf life of kaifeng is there a difference? Will quickly deteriorate after cosmetics manufacturer in kaifeng? How to correctly use and save cosmetics? What's the difference between before and after the shelf life in kaifeng? Shelf life is often measure a product quality is good or bad, one of the important factors for cosmetics packaging on the shelf life is generally for unopened products. before and after the shelf life of kaifeng, then, is there a difference? The expert points out, the shelf life of cosmetics manufacturer is generally refers to the storage time of cosmetics in a sealed condition. In the case of no kaifeng, shelf life is about 2 ~ 4 years, different kinds of cosmetic shelf life is slightly different. Such as eye shadow, mask, cheek is red, perfume, liquid foundation, scrub and other general is 1 ~ 2 years; Sunscreen, creams, lipsticks, etc for more than 3 years commonly. Warranty period of cosmetics in the condition of unopened, stored in appropriate conditions, the internal quality is guaranteed. And once kaifeng, cosmetic effect of certain ingredients such as vitamins or SOD ( Superoxide dismutase (sod) Such as the active ingredient, due to its chemical properties is not stable, chemical changes will happen after environmental changes, may affect the use effect; In addition, cosmetics after opening, it will be exposed to some sources, storage environment, usage, etc are likely to affect the shelf life time length. In the production of cosmetics, however, will add a certain amount of preservatives, although has contact with air, finger, etc, may be introduced some pollution sources, but a bottle of cosmetics life for a few months to a year, usually few cosmetics so bad can't use. But from the perspective of security, effective Angle and the use of comfort, every kind of cosmetics in the emphasis on the package in the warranty period. And consumers also want to use up as soon as possible after open a bottle of, hoarding and buy large packaging products are unwise. After opening the shelf life of difficult to label since cosmetics in kaifeng there are a lot of uncertainty, it is difficult to guarantee the quality of cosmetics is consistent, so why not mark on the packaging of cosmetics production enterprises after opening the shelf life of? on the market at present, there will be on the package & quot; Please use before the dates & quot; Or & quot; Please use the warranty & quot; With the words such as tip. There are some imported cosmetics, packaging & quot; Open a small jar & quot; The icon, or below the internal & quot; 6 m” Or & quot; 12M' Words, such as YanShi moisturizer and facial cream inside the ICONS on the annotation for & quot; 12M' , estee lauder essence for & quot; 24M' , perfect facial cream and moisturizer for & quot; 6 m” , thefaceshop foam cleanser for & quot; 12M' , lancome's toner is & quot; 12M' And so on. ” M” On behalf of the month, the meaning of these signs is after opening this time ( Such as 6 months, 12 months and 24 months) As the best life. We have learned, cosmetics manufacturers is not marked on the package after opening the use of the term, the reason is that there is much uncertainty cosmetics after opening. Although after opening the shelf life of related to product formula, but the reason and degree of secondary pollution is difficult to forecast. So, to accurately give the consumer must guarantee, enterprise must first guide consumers use cosmetics, correct such as using the cosmetics, should be in a clean environment, with a clean cotton swab, small spoon, such as pick, instead of access directly to a finger into the bottle, and should indicate the preservation conditions and so on. Only use cosmetics that, according to the requirement, however, many consumers are difficult to adhere to. So, once the use of cosmetics in kaifeng after bad happen within the time limit, also it is difficult to determine is the product of the formula, or production process the results of the pollution, or transport, sales and consumer use secondary pollution caused in the process. Because it is difficult to determine the cause of the bad, and it is difficult to define responsibility attribution, it is not easy to give the consumer commitment. Use of storage has exquisite. According to expert introduction, for the shelf life of cosmetics, various production enterprise according to the production of raw materials, production process, such as anti-corrosion system specific situation and determine. Similar products of different enterprises, different products manufactured by enterprises in the same shelf life is different.
