Will glycerin expire or explode?

Glycerin is generally used for skin care and moisturizing the skin, so will glycerin expire? Can glycerin explode?

Does glycerin expire?

Yes, but the shelf life is very long, and it is unlikely to expire because you may have used it up before that. The shelf life of glycerin will be written on the packaging or bottle, so you will find it if you look carefully.

It depends on the outer packaging of your glycerin. There is a shelf life on the packaging, which is usually 3 years. If the bottle has been opened and used, it probably won't last that long.

Glycerin is hygroscopic and can absorb moisture in the air to moisturize the skin. This method is only suitable in areas with humid air. In areas with dry air, there is too little moisture in the air for glycerin to absorb, so it will absorb moisture from the skin, causing the skin to become drier and drier. Therefore, it is best to use glycerin when the air humidity is above 50%.

100% pure glycerin cannot be used directly. Not only is it irritating to the skin, it will also quickly absorb moisture from the skin, causing it to become dry and flaky, and it will also make the skin breathable. However, the bottled glycerin we buy in pharmacies and supermarkets is generally a diluted glycerin water solution and can be used with confidence.

Will glycerin explode?

Glycerin generally does not explode, but it will explode under certain circumstances.

Glycerin may explode when in contact with strong oxidants such as chromium trioxide, concentrated hydrogen peroxide, and perchloric acid under certain conditions.

Okay, my friends, you all understand clearly, glycerin has a shelf life.
