What is the GB4806 standard for silicone tableware sales in China?

The choice of tableware is often closely related to our health and safety. With the development of modern technology, the production of tableware is also diverse. Among them, silicone tableware has been widely loved in recent years, with its high safety, soft texture, anti slip, impact resistance, and high temperature resistance, making it the preferred material for household daily necessities such as children‘s products and kitchen utensils. The country also needs to comply with the GB4806 standard for the sales of silicone tableware. So what is the specific GB4806 standard? Next, let‘s talk about this topic!

When choosing silicone tableware, safety is the primary consideration and must comply with the limitations of GB 4806.11-2016 National Food Safety Standard for Rubber Materials and Products in Contact with Food.

The standard mainly stipulates that the appearance color of silicone products is normal, there is no odor, the surface is free of dirt, the total migration amount, potassium permanganate oxygen consumption, and the maximum migration amount of heavy metals (measured in Pb).

We can understand the total migration amount as the residue requirement for non-volatile substances. The maximum limit for silicone tableware used by adults is 10mg/dm2, and the maximum limit for silicone tableware used by infants and young children is 60mg/kg. These non-volatile substances entering the human body may have adverse effects on human health, affecting the quality of food consumption. The more non-volatile substances migrate, the higher the safety risk.

Potassium permanganate oxygen consumption is the basis for determining the organic matter oxygen consumption in silicone tableware, with a maximum limit of 10mg/kg. Excessive consumption of potassium permanganate can cause varying degrees of damage to the human body, such as memory loss, nausea, palpitations, and other symptoms.

Heavy metals (measured in Pb) are the standard for measuring heavy metal substances in silicone tableware, with a maximum limit of 1mg/kg. If silicone products contain excessive heavy metals, they are easily soaked and dissolved by liquids, which can accumulate in the human body and affect and damage the heart, liver, kidneys, skin, gastrointestinal tract, respiratory and nervous systems. The lower the value of heavy metal (measured by lead) detection results, the less potential harm it poses to human intake.

The above are the specific requirements of GB4806 standard, and based on these indicator standards, we can determine whether the chemical properties of silicone tableware meet the requirements.
