Glycerin is widely used in the medical, cosmetology and food industries as an important component. Glycerin is used to create creams, masks, lotions and other cosmetics that you can prepare yourself at home. Therefore, it will not be superfluous to learn the methods of use, properties, positive and negative features of the useful substance.
Glycerin - what is it?
Glycerol
is a moisture-retaining substance from the class of trihydric alcohols, which is widely used in the cosmetics industry and is part of moisturizing, softening and anti-aging products. The chemical formula of glycerin consists of three water molecules, which explains its hygroscopic ability to absorb water molecules from the air, accumulate them in cells and prevent transepidermal moisture loss.
Glycerin in its pure form is a syrupy, clear liquid with a sweetish taste. The component gained its popularity in cosmetology due to its low cost and high efficiency. Glycerin for the face can be found in the basis of the formulas of various cosmetic products: emulsions, creams, gels, masks, soaps and is suitable for caring for problematic and sensitive skin types.
There are several ways to make glycerin: plant, animal and synthetic production. Let's take a closer look at its forms.
Natural (natural) glycerin
In nature, the substance is found in oils and fats: animal glycerin is made from pork fat, vegetable glycerin is a derivative of palm oil, coconut oil is the most accessible and safe. The plant-based production method is the most common and is considered more environmentally friendly. It is natural vegetable glycerin that is used in cosmetology and pharmacology and is characterized by high quality and safety.
Synthetic glycerin
The industrial production method is the synthesis of glycerin from propylene. There are two synthesis technologies: the chlorine method (by chlorination of propylene) and the chlorine-free method (oxidative method through acrolein). The synthetic form of glycerin has a low degree of purity and is most often used for technical purposes.
Description and classification
Glycerin is a chemical substance (trihydric alcohol) obtained by processing fats. It is divided into 2 types: plant and animal origin. The latter is used when creating cosmetics.
There are two more varieties:
- synthetic;
- natural.
Many cosmetologists recommend using natural ones, although recent research by scientists has proven that these types are no different from each other, and in some cases it is quite difficult to accurately determine the identity of the substance.
In any case, the formation of a substance occurs as a result of a chemical process. This division is conditional, and the properties of both types are the same.
