What exactly is propylene glycol?

Can it be added in food?

What are the dangers of long -term intake?

Let's understand today

What is propylene glycol? What effect does it have?

Strictly speaking, propylene glycol includes two homogeneous differentials: 1,2-propylene glycol and 1,3-propylene glycol. The latter is mainly used as a solvent in industrial and production. Therefore, the propylene glycol often mentioned in life refers to 1,2 1,2 refers to 1,2 -Onol.

Pateyl glycol is an organic compound. It is almost tasteless viscous liquid at normal temperature. It has a stable chemical properties and has a certain water absorption. Its toxicity and irritation are very small.

Pingyl glycol has a wide range of uses in industry and life:

It can be mixed with water and can dissolve organic matter, so it is widely used as solvents in the chemical industry;

In cosmetics, soap and toothpaste, propylene glycol is often used as a wetting agent, moisturizing agent and antifreeze;

At the same time, it also has certain applications in the field of resin synthesis and pharmaceuticals.

Can propylene glycol be added to food?

For the additives in food, my country has introduced a detailed GB2760-2014 "Standard for the use of food safety national standard food additives". The standard stipulates that propylene glycol can be used as a synthetic spice in food. The main function is stabilizer, coagulants, antidents, anti -foaming agents, emulsifiers, moisture holders and thickeners.

However, the national standard also stipulates that the use range of propylene glycol is limited to humid noodle products (noodles, dumpling skin, ravioli skin, etc.), pastries (such as Chinese pastry, western pastry, moon cakes, etc.) and edible decorations for cakes.

Among the wet noodle products, the amount of propylene glycol must not exceed 1.5g/kg;

The maximum amount of propylene glycol is 3g/kg in the cake and its edible decoration.

Therefore, as a food additive that is very toxic and allows the state, as a low toxicity, the state is allowed to be added to some foods without exceeding the content, and propylene glycol is not allowed to be allowed by the national standard.

What are the dangers of intake of propylene glycol?

As a national statutory food additive, propylene glycol does not cause health harm to the human body when normal food compliance standards.

For the harm of propylene glycol to the human body, it is necessary to comprehensively consider the content of propylene glycol in food and the frequency of intake of food.

Disposal intake of propylene glycol is risk of causing kidney disorders, and long -term consumption of menol foods may cause propylene glycol to accumulate inside the kidneys and cause harm to human health.

Pateyl alcohol is in life

What industries are still applied?

In addition to as food additives, there are padols in many places in life, such as cosmetics, skin care products, toothpaste, etc. we use daily.

The role of propylene glycol is mainly in the following three aspects:

(1) Moisturizer

Polycol and glycerin are similar to a certain amount of water absorption and water preservation capacity. The moisturizing performance of proplycerin is softer and moderate compared to glycerol. Therefore, propylene glycol is often added as a moisturizing agent in cosmetics and skin care products to enhance the moisturizing performance of the product.

(2) Frozen agent

Cosmetic and skin care products can effectively reduce the freezing point of the liquid after propylene glycol, so that the liquid is not easy to freeze solidified at low temperature, and it is convenient for the preservation and use of winter cosmetics and skin care products.

(3) Slipper

The penetration performance of propylene glycol is strong and the dissolution and dispersing performance of organic matter can be better. When adding cosmetics and skin care products, it can help other ingredients evenly disperse on the skin surface and promote the skin absorption of the skin.

In addition, propylene glycol in toothpaste can also be used as a wetter with glycerin and coserol; in the hair dye, propylene glycol can also help the hair dye to better disperse on the hair, and at the same time play a role in moisturizing and moisturizing.

In summary

Pateyl alcohol has a wide range of applications in life

It is also allowed

As a food additive

Add to some specific foods

Normal consumption of these compliance foods

It does not cause harm to human health
