Uses and properties of glycerin or glycerol


The glycerine or glycerol is a compound obtained from lipids. It is an alcohol and is used mainly in the cosmetic industry, since it is among the ingredients of moisturizers and soaps that provide softness and turgor to the skin. That is, it fights dryness thanks to its moisturizing properties.

However, like petroleum jelly, it has many more benefits in skin care, fighting cell aging. In this article we explain what glycerin is for, what are all its uses, how to make it at home and where to buy it.

What is liquid glycerin for and what are its uses?

Making homemade creams

The most important property of vegetable glycerin is hydration. If you normally make creams at home, integrate it as an ingredient, and if not, you can add a few drops to the cosmetic you buy. At first it feels sticky, but after a few minutes it is completely absorbed, so you will notice smoothness and better penetration of the serum or oil.

Note: Do not forget that glycerol interacts with water, try combining it with oils or a cream for dry skin, if it could not promote dehydration.

Soothing effect on the skin

Liquid glycerin is a great natural remedy for some skin conditions like burns, irritations, and acne. Its soothing action extends to mosquito, spider and other insect bites, as well as inflammations or small wounds. In addition, being antibacterial, glycerol serves to disinfect the cosmetic if you dissolve a few drops before applying it to a dry face.

Strengthens hair

In the same way that it is used on the skin, glycerin is effective in hair treatments. Moisturizes the strands, strengthens the roots and strengthens it, preventing its fall. To prepare it, put equal parts glycerol and water in a bowl. Stir it well until it dissolves and apply the mixture all over the hair.

The mane improves noticeably after two or three weeks applying this treatment two days a week. No more frizz and frizz. You can also buy a hair product that contains glycerol.

Making homemade soap

There are many places where you can buy solid glycerin. If you already have, chop it up and put it in the microwave or in a water bath for a few seconds. When it’s liquid, put it in a soap mold and wait for it to solidify again. This glycerol will help you clean your face, hands and body.

The advantages of natural soap are clear: it is inexpensive, you will save a lot of money, the process is very simple and you can personalize it with essences and natural ingredients such as rosemary, royal jelly, raspberry, mint or green tea.

As a mouthwash

From here we start with the internal uses of glycerol. You should first consult a doctor or pharmacist to avoid falling into contraindications. Due to its antimicrobial property, there are people who rinse their mouths with glycerin by gargling, thus fighting halitosis. Another option is to add a few drops to your regular mouthwash or toothpaste.

To decongest

If you have a cold, glycerin will be great for you. Add a couple of drops of glycerin to half a cup of water to ease congestion. Apply it inside the nose and in a few minutes you will clear the nostrils. The air will pass freely again because the glycerol softens the nasal congestion. You will love the results and you will breathe like never before!

Fight constipation

If you suffer from gastrointestinal disorders, glycerin is a great solution to calm them. Taking two teaspoons for dessert, you will benefit from its laxative effect to go to the bathroom more easily. However, you should not exceed the dose, since you could experience some side effects. Consult your doctor before self-medicating.

Fact: Did you know that some of the suppositories sold have glycerol? You will find them in pharmacies.
