What are preservatives? Why add preservatives?
The role of preservatives is mainly to prevent the growth of microorganisms, reasonably extend the shelf life of the product, and ensure that the product will not deteriorate due to pollution during use. Therefore, in order to ensure the safety of cosmetics and prolong the service life, it is necessary to add preservatives! ⤵️：
China has formulated strict standards for the use of preservatives in cosmetics, and the use needs of preservatives added to cosmetics must comply with the "Cosmetic Safety Technical Specifications" (2015 edition).
Cosmetics Permitted Preservatives (Cosmetic Safety Technical Specification, 2015
The current Cosmetic Safety Technical Specification (2015 edition) stipulates the maximum allowable concentration of 51 cosmetic preservatives and when used, and stipulates the scope and restrictions on the use of some preservatives, as well as the conditions of use and precautions that must be marked on the label.
Therefore, cosmetics that are strictly in accordance with the "Cosmetic Safety Technical Specifications" to add preservatives are relatively safe.
What if you don't use preservatives?
In our living environment, there are a large number of microorganisms, skin care products are rich in nutrients, can provide a good growth environment for microorganisms, equivalent to a Petri dish, when no preservatives are added, skin care products will grow freely after opening the microorganisms, and your skin care products will grow countless bacteria. At this time, when you rub it on your face, do you think you are applying skin care products or bacteria?
Is "Zero Additive" Preservative Skincare Trustworthy?
99% of the skin care products on the market that advertise "zero added" preservatives are misleading!
Skin care products that do not add preservatives at all or have a particularly short shelf life and must be used up immediately after opening;
Either in the texture, formula and outer packaging must meet some hard conditions, for example, the use of capsule-type independent packaging, vacuum packaging and other packaging forms; or the product is pure essential oils, dry powder preparations, anhydrous oil-free products; or high alcohol content of skin care products and makeup do not need to add preservatives, because alcohol also has a bactericidal disinfection effect, only if one of the above conditions is met, the skin care products you buy may be "zero additive" preservative products.
The "zero additive" preservatives claimed by many merchants are not really no preservatives, but a raw material ⤵️ with antiseptic effect but not in the list of preservatives is added!

The difference between "zero additive" preservatives and "additive-free" preservatives
"Zero additive" preservatives have been mentioned earlier, that is, no preservatives are added, but due to factors such as product form and storage time, most products cannot be realized.
However, traditional preservatives have a greater impact on the skin, so many skin care giants have chosen to add antiseptic effects, but not in the list of raw materials, this skin care products are called "additive-free" preservative skin care products.
"Additive-free" preservative skin care products began in the 1990s, when the Japanese government established a standard for 102 ingredients designated by the cosmetics industry to define substances harmful to health and skin that cannot be added.
The so-called "additive-free" means that in the process of production and sales, no ingredients that are sensitive and harmful to the skin are added to avoid "incense pollution", "color pollution" and "oil pollution", causing harm to the consumer's body, including fungicides, preservatives, acidification prevention agents, artificial flavors, artificial colors, oils and surfactants.
"Additive-free" cosmetics are based on organic plants as the main raw material, no artificial flavors, artificial colors, no petroleum ingredients, the added preservatives and surfactants must be strictly restricted, and the manufacturing process must comply with relevant regulations, can not use animal experiments and the use of radiation sterilization products.
More importantly, raw materials for skin care products with or without additives are required to be free from genetic variants and artificial chemical additives in the environment (such as soil) and process of cultivation, production, extraction and production.
Compared with traditional preservatives, these "additive-free" preservative products have no impact on the skin, after all, this preservative does not belong to the category of preservatives, but belongs to moisturizers, skin conditioning agents, and has a good antiseptic effect, is the best "preservative" so far. Friends who are sensitive to preservatives can preferentially choose products that add this preservative to use.
Finally, although we said earlier, as long as the preservatives meet the national norms, it is relatively safe, but for the potential risks we still have to pay more attention, the following preservatives are preservatives with a relatively high risk factor, when choosing products such as masks, eye creams, essences, etc., the pursuit of safety and higher quality you should pay more attention ⤵️:
· Preservatives with high hazard factors ·
1. Formaldehyde release system: DMDM hydantoin, imidazolyl urea, bis (hydroxymethyl) imidazolyl urea, etc., release formaldehyde, harm to the skin;
2. Paraben esters: methylparaben, ethyl hydroxyphenyl ester, propyl hydroxyphenyl ester, hydroxyphenylbutyl ester, isobutyl hydroxyphenyl, etc., and UVB reaction, may cause skin aging;
3. Isothiazolinone: methyl chloroisoxazolinone, methylisothiazolinone, etc., in 2013, the EU has stopped using it due to health hazards.
The above preservatives have potential carcinogenicity, irritation and allergy problems, and must be paid attention to when choosing!
In short, most of the cosmetics on the market are to add antiseptic ingredients, for a long time in contact with the skin of cosmetics, such as masks, essences, etc., we should pay special attention to the safety of preservatives or antiseptic ingredients when choosing products, especially sensitive skin friends, "additive-free" cosmetics are your good choice.
