All cosmetics has Preservatives additive

Let's start with the fact that we have to accept that basically all cosmetics have preservatives added. As a nutrient-enriched product, cosmetics are suitable for the growth of various microorganisms. If they are not inhibited by effective means, they will deteriorate, mildew, etc. The main microorganisms that preservatives are added to cosmetics are secondary pollution brought by consumers, such as microorganisms in the air.

In this way, in fact, the addition of preservatives in cosmetics is still in the consideration of the safety of the product for a long period of time. Preservatives are also added to various foods that we usually eat, and the reason is the same.

Most preservatives are relatively safe, otherwise they cannot be legally added to the product. Cosmetics upstream companies, when designing formulas, if there are no special requirements, the standard for the dosage control of preservatives is: the minimum dosage is added on the premise of achieving the preservative purpose. On the one hand, it can reduce the risk of cosmetic safety problems; on the other hand, adding less preservatives can also save raw material costs.

Methyl isothiazolinone preservative (MIT)
MIT is a chlorine-free preservative that inhibits the growth of bacteria, fungi, and mold. MIT can effectively kill a variety of bacteria at low concentrations, and is particularly suitable for the storage of cosmetics and personal care products. Therefore, MIT is widely used as a highly effective preservative in cosmetics and personal care products. But it is easy to cause contact dermatitis, which has a greater impact on children. In 2016, the European Commission issued (EU) Regulation No. 2016/1198, banning methyl isothiazolinone as a preservative in resident cosmetics (such as creams), and only allowing it to be used in rinsing cosmetics (such as face wash, washing Hair), the maximum concentration is 0.01%. On July 6, 2017, the European Commission issued (EU) Regulation No. 2017/1224, further revising the maximum amount of methyl isothiazolinone in rinse-off cosmetics from 0.01% to 0.0015%.
China's "Cosmetic Safety Technical Specification" (2015 edition) refers to EU regulations, stipulating that the maximum allowable concentration of methyl isothiazolinone in cosmetics is 0.01%, but methyl isothiazolinone is not prohibited from being used in resident cosmetics.

IPBC preservative (3-Iodo-2-Propynyl Butylcarbamate)
The English name of iodopropynyl carbamate is IPBC, which has a broad spectrum of antibacterial activity, especially has a strong anti-kill effect on molds and yeasts. It is currently the most effective antifungal agent and can be used with many preservatives. The agent is used in combination for good compatibility.
Because butyl iodopropynyl carbamate may cause iodine intake, the label must be labeled "Do not use for children under three years old". The maximum allowed concentration of leaching products is 0.02%. It is forbidden to use on lip products. The maximum allowable concentration of resident products is 0.01%. It is forbidden for lip products and for body cream and body milk.

Bronopol Preservative
Bronopol is the abbreviation of 2-bromo-2-nitro-1,3-propanediol. It has a broad-spectrum antibacterial effect and can effectively inhibit most bacteria, especially gram-negative bacteria. The effect is excellent. It is unstable under high temperature and alkaline conditions, it will decompose and release formaldehyde, and it will decompose and turn yellow or brown.
Bolopol may lead to the formation of carcinogenic nitrosamines, which are banned in Japan. The EU and China require a maximum allowable concentration of 0.1% in cosmetics. The restrictions are to avoid the use of amine raw materials and avoid the formation of nitrosamines. Addition of antioxidants inhibits the formation of nitrosamines.
