Warm baby is a kind of warm products commonly used in winter, it is more convenient to use, generally only need to tear the sticker, and then stick on the clothes above, you can heat and warm, loved by people. Is the warm baby hard or soft? Let’s take a look at it.

The warm baby is hard or soft
Warm baby is soft before use, after use will become hard.

The hardening of warm baby should be due to oxygen oxidation after opening the package. If some of the contents are oxidized, the heating effect is reduced. If the ingredients are completely oxidized, the body will not be heated.

Warm baby will harden, most likely due to air leakage. Warm baby heating material is made of iron powder, activated carbon, vermiculite, inorganic salt and water composed of polymer. It can tear apart the glue layer and immediately react with the oxygen in the air, producing an exothermic reaction.

Why does warm baby become hard
Warm baby will harden and clump when used because it takes advantage of the oxidation reaction of iron to release heat. In fact, it is based on the principle that iron is corroded by oxygen in moist air. At the same time, water vapor is stored in the loose structure of activated carbon due to its strong adsorption. Water vapor liquefied into water droplets, outflow contact with air and iron powder. Catalyzed by sodium chloride, the reaction quickly produces ferric hydroxide and exotherms. It hardens naturally when the oxidation reaction is complete.

From this, we can also draw a conclusion that if the warm foot cream is very hard before use, either the product has expired, or the product packaging has leaked, but in any case, Xiaobian do not recommend that you continue to use, or buy. Also, not only the foot warmer stickers, but other baby warmer stickers can get lumpy. Warm baby clumps are due to warm baby has been exposed to air, or damp. Harden warm baby, for their own health, it is best not to use.

Warm baby use precautions
1. Don’t use “three No products”. Choose a brand “Warm Baby,” but don’t assume it’s real just because of the brand name and production date on the package.

2. Do not apply directly to your skin. The “Warm baby” has a fever of up to 60 degrees Celsius and can be applied directly to the skin within five minutes to cause hypothermia burns. So, stick it on the outside of your underwear and smooth it out.

3. Don’t stick “warm baby” to the same area for a long time. On the one hand, warm skin doesn’t breathe, on the other hand, it also prevents skin burns.

4. Not suitable for use with other heating tools. If the word “warm baby” is already attached to the body, do not use the heater and other equipment, so as to avoid scalding the local overheating skin.

5. Don’t use it in your sleep. Sleeping quilt can play a role in keeping warm, so that the heat generated by warm babies can not be sent out, causing harm to the human body. The body, on the other hand, is more prone to burns as its senses are reduced during sleep.
