The merchant claims that the cooling spray can quickly cool down, does not contain chemical ingredients, has zero harm to the human body, and can be used with peace of mind.
Is this cooling spray really reliable?

Cooling artifact
The merchant says it is non-toxic and harmless
Recently, an online celebrity artifact "cooling spray" has quietly become popular.
After the reporter searched for "cooling artifact" on the shopping platform, a variety of spray products appeared, with prices ranging from a few yuan to tens of yuan, and many shops sold more than 10,000 a month.
Subsequently, the reporter randomly selected a canned cooling spray for detailed understanding.
According to the business, the product has a wide range of uses, such as cooling car interiors, outdoor high temperature heatstroke prevention, alleviating sports injuries, etc., seats, backrests, steering wheels, skins and other surfaces that need to be cooled can be used.
The store’s sales page shows that the main components of the product are flavors, propellants, and cooling factors. The physical cooling principle is adopted. The liquid vaporizes and absorbs heat for cooling. The principle is that the cooling factor propellant quickly vaporizes when heated and absorbs surface heat.
When asked what the cooling factor is, the business began to flicker, saying that it is only one ingredient and will not affect human health.
This situation is not an isolated case.
The product descriptions of many stores did not indicate the detailed ingredients of the products, and most of them were labeled as "propellant" and "cooling factor".

The spray ignites in an open flame
On July 13, the reporter brought a cooling spray purchased online to the full-time fire brigade on Chenglong Road.
The product is also not marked with specific ingredients, but at the end of the precautions, "Hydraulic Gas: LPG" is marked in a small font.
Zhang Kaixin, a full-time firefighter of the Chenglong Road fire brigade, said that the main component of this product is high-pressure gas-LPG.
LPG is the English abbreviation of Liquefied Petroleum Gas. The main component is a mixture of propane and butane. The explosion range is 1.7-9.7. It will deflagrate when it encounters an open flame.
LPG is stored in a storage tank in a liquid state under appropriate pressure. It is often used as a cooking fuel, that is, commonly used liquefied gas. This product is not only flammable, but it may explode when placed in a high-temperature car for a long time. It is used directly on the skin. May cause frostbite.
In order to understand the dangers of this product more intuitively, after wearing protective equipment, Zhang Kaixin conducted two small experiments on site.
In the first experiment, Zhang Kaixin sprayed the cooling spray at the leaves that were just picked. After just a few seconds, the leaves quickly frosted, and the soft leaves were crushed with a gentle hand.
What kind of effect will be produced if it is sprayed directly on the human skin?
After the reporter sprayed the cooling spray at his arm for a few seconds, the smell was pungent, followed by a cold sting.
Immediately afterwards, the firefighters conducted a second experiment.
First spray the cooling spray in the direction of no one, while slowly approaching with a fire source.
In an instant, the spray in the air was quickly ignited, forming a huge flame.

He pointed out that this kind of cooling spray containing LPG ingredients has certain risks in storage and transportation. If it is left in the car for a long time, as the temperature in the car rises, it may explode, and during the placement process, avoid violent Keep away from the source of fire when you hit it and use it at the same time. It is not recommended to use it directly on the skin.
