1. Regardless of the size of the brand, must be certified by the relevant state departments.
Food grade silica gel is made of silicic acid polycondensation of inorganic polymer colloidal material, the main component is SiO2 · nH2O, its content in more than 98%, non-toxic and tasteless, chemical stability, in addition to normal caustic and hydrofluoric acid , And does not react with any acid and alkali salt. Currently on the market of infant products related to silicone rubber materials, the level is divided into pharmaceutical grade silicone rubber and food grade silicone, which drug grade silicone standard higher, need to go through the National Food and Drug Administration certification Caixing. China's infant market products generally follow three national standards: China, the United States, South Korea. Regardless of the product is the implementation of the national standards, only through the State Food and Drug Administration certification, to ensure that is genuine. In the purchase must see.
2. Latex, rubber fish head to teach you three strokes screening
As the consumption of silicone rubber is refined and sterilized, and food and pharmaceutical products can be mixed after the need to directly ensure the dry food and food with food, and the human body without any side effects. Therefore, pay attention to the baby entrance safety parents are biased towards silicone materials made of infant products, and Mr. Gong pointed out that the current infant products, there are many latex, rubber posing as silica gel phenomenon, and even the industry have to carefully identify the talent Separate true and false. Professionals generally choose the following three strokes:
The first test flexibility: rubber, latex elasticity is better, more fragile silica gel, in the selection, you can try the flexibility, if the elasticity is very good, there may be rubber;
The second look at the color: rubber, latex due to impurity content, mostly light yellow, and then after chemical treatment into white, and the real silica gel is colorless and transparent, so transparent material for the silicone;
The third smell: rubber, latex products taste thick, smell a smell will smell the pungent smell, some manufacturers in order to cover up the taste and increase the flavor, so to choose no fragrance of the material.
Finally, the silicone production process itself is more complex, and good quality silicone bottles are made of food grade or top medical grade silicone made, so the price will not be particularly low, so do not think when the purchase of cheap and buy cheap Silicone products.
