Talk about people's understanding of cosmetics preservatives

At present, cosmetics is commonly used chemical preservatives to achieve antibacterial, antibacterial and reasonable to extend the shelf life of the purpose of the product.

 

It is understood that the world reported more than 200 kinds of cosmetic preservatives, of which the use of p-methoxy benzoic acid is more extensive. China's cosmetics on the use of preservatives have strict rules, the cosmetics have been used in the directory can be used in the 55 kinds of preservatives, and are added to the cosmetics to inhibit the growth of microorganisms in the cosmetics for the purpose of the material, each anti-corrosion Agents are specified in the maximum allowable concentration, scope of use and restrictions, some preservatives also specify the label must be marked on the use of conditions and precautions.

 

"Does not contain preservatives", which is the current cosmetics publicity in an important selling point. After experiencing serious side effects of cosmetics, consumers began to pay more attention to each of the cosmetic ingredients will bring their own potential harm to the skin. Thus, easy to cause skin allergies and other issues of preservatives will be included in the list of potential hazards of cosmetics, consumers are more inclined to choose the so-called "natural, non-preservative" cosmetics. So, how do consumers rationally look at preservatives in cosmetics? Is it a cosmetic that contains a preservative?

 

First of all, let's know about the preservatives in cosmetics. Preservatives are additives to prevent deterioration of cosmetics, the purpose is to kill and inhibit the cosmetics in the micro-organisms, to prevent secondary pollution of cosmetics. At present, the main raw material used in cosmetics is based on the Ministry of Health issued the "Cosmetics Hygienic Standard" (2007 version) (hereinafter referred to as "norms"), provides limited use of cosmetics in our country there are 56 kinds of preservatives. At present, the most widely used preservatives at home and abroad include benzoic acid and its derivatives, phenoxyethanol and other alcohol preservatives. As the main components of cosmetics are water, grease, protein, etc., are microbial organisms are easy to breed, and microbes can lead to cosmetics corruption, and even lead to allergies, therefore, in order to extend the shelf life of the product, the general cosmetics will contain preservatives , And in accordance with the relevant provisions of the appropriate amount of added, usually does not cause damage to the skin.

 

Since the addition of appropriate preservatives in cosmetics is an important means of ensuring the quality and safety of products in production, then the so-called "preservative-free" cosmetics are authentic? I believe that the current do not add preservatives and have a longer shelf life of cosmetics is not easy, businesses in the publicity "no preservatives" in the more or hit the edge of the ball. First, the cosmetics are produced from a variety of raw materials, and these raw materials are sent to the manufacturer before the factory may have added their own preservatives, and according to national standards, to protect the raw materials added to the amount of preservatives may not have Ingredients are marked. Second, many manufacturers simply do not use the "standard" preservatives, but the use of microorganisms can not survive the solvent to replace the use of preservatives, such as antibacterial effect of polyols, 1,2-pentanediol (1,2-Pentanediol), 1,2-hexanediol (1,2-021Hexanediol), although this ingredient is not a preservative, but has a significant anti-corrosion effect.

 

In short, the addition or absence of preservatives in cosmetics is not absolutely good or bad. In other words, cosmetics that do not use preservatives may lead to more uncertain risks. Therefore, the Shanghai Airport Inspection and Quarantine Bureau to remind consumers, in the choice of a wide range of cosmetics, to see the label on the composition, do not blindly listen to business propaganda, do not talk about preservatives discoloration, the right choice for their own cosmetics.
