Vegetable glycerin is a triatomic sugar alcohol. Outwardly, it looks like a thick, odorless, colorless liquid. It has hygroscopic properties, it is soluble in water, non-toxic. The substance is obtained by chemical synthesis of plant or animal raw materials. In addition, the product is formed during the production of biodiesel and during the cooking of soap. In the article, we consider vegetable glycerin, its properties and effects on the human body.
Glycerin in the cosmetics industry
This substance is available in today's market. You can buy glycerin in almost any pharmacy for ridiculous money. Trihydric alcohol has become especially popular in cosmetology. Due to its hygroscopic properties, it is widely used to moisturize the skin. It has long been known that aging processes develop due to the loss of moisture by cells. Compensating for its deficiency, a noticeable rejuvenation of the skin can be achieved. In addition, vegetable glycerin has a softening effect, and also promotes the healing of damaged sections of the epidermis and its restoration.
How exactly does this chemical compound work? It attracts water molecules from the environment. That is why the use of glycerin should be correct and reasonable: in cases where there is no place to attract moisture, skin will serve as its source. By taking water molecules from the dermis, the trihydric alcohol will act the other way around. To avoid this, you should adhere to the instructions for use.
The “right” glycerin for the skin
Directing the action of sugar alcohol for the benefit of the epidermis and dermis is not so difficult. In cosmetics (lotions, creams, soaps), the glycerol content is quite low (5–7%), since the compound must be diluted with water and other components. As it was found out, the effective formula of sugar alcohol is the manufacture of an emulsion with water. If vegetable glycerin is dissolved in water, then its molecules will begin to attract water molecules. This phase of the substance contributes to a better and more natural skin hydration. Otherwise, glycerin will not only not bring benefits, but also harm.
Using the substance at home, you should remember this. Masks need to be made with glycerin diluted with water. Its use in its pure form can be justified only with a sufficient level of room humidity (45% or more).
Useful properties of glycerin in cosmetology
This compound has been successfully used in the treatment of many dermatological diseases as an emollient. Glycerin promotes faster penetration of the active substances of the drugs into the dermis. That is why it is prescribed in complex therapy or included in the composition of many drugs. A protective film forms on the surface of moisturized skin, which prevents bacteria, viruses or dust particles from entering the epidermis. In addition, glycerin has the following advantages:
- exhibits stabilizer properties in homemade lotions, masks;
- promotes skin renewal and rejuvenation;
- is an activator of metabolic processes;
- removes toxins, excess sebum and helps cleanse the skin.
Glycerin is successfully used for deep restoration of damaged areas of the epidermis. For example, with cracks in the elbows, heels, knees. On the basis of this sugar alcohol shampoos are made for weakened and dehydrated hair.
The negative effect of glycerol on the skin
Any chemical substance can adversely affect human health. Plant glycerin does harm only when it is used incorrectly. The main disadvantages of this simple cosmetic include:
- “aggressiveness” with improper dosage and prolonged use;
- in its pure form dries out the skin, leads to loss of moisture;
- may adversely affect sensitive and inflamed skin;
- leaches melanin from the epidermis.
It is also worth knowing that it can not be mixed with silicone, because a toxic and dangerous substance is formed as a result.
Vegetable glycerin in a pharmacy is inexpensive, and therefore it becomes a favorite tool of women in pursuit of beautiful skin. When using it, care should be taken that the substance is diluted with water. Before use in large areas, perform an allergy test.
Plant glycerin: the harm and benefits in food
The properties of sugar alcohol were evaluated not only by cosmetologists, but by technologists of the food industry. Glycerol, more commonly known as E422, is used as a stabilizer, sweetener or thickener. It can be found in almost all cakes, cakes or sweets. For example, E422 in a significant amount is part of the Bounty bar to create a soft structure. It also boasts Bird's milk or products such as marmalade, iris, marshmallows or marshmallows. In them, E422 plays the role of a water-retaining component. It is also found in alcoholic beverages for the softness of their structure, in baked goods to increase its shelf life, in dairy products, jams and preserves.
Of course, most substances labeled “E” are more or less dangerous to human health. This can not be said about glycerin. It is not toxic and does not have mutagenic, carcinogenic or other harmful properties. Nevertheless, it is not recommended to consume it in large quantities. It can lead to dehydration and cause impaired blood circulation and kidney function.
Glycerin in other areas
In addition to applications in cosmetology and the food industry, glycerol is actively used in pharmacology. On its basis, laxatives in the form of candles are released. They also help to heal cracks in the anus. A glycerol solution is used to reduce intracranial and ocular pressure and reduce brain edema.
With the development of electronic cigarettes, sugar alcohol has become a major component in smoking fluids. It is worth noting that plant glycerin practically does not harm the body. The main thing is to observe the dosage and do not mix it with other chemical compounds.
Glycerin is an affordable treatment for dermatological and some other diseases. It is a common component of cosmetics and skin care products for hair and skin. It is often found in foods as a food supplement E422, but does not affect human health.
