Basic properties
Glycerin is able to bind the amount of water in twenty times greater than their own, that is what causes it humectants and moisturizing properties. Thickening and emulsifying effect of the drug can be used for the production of viscous gels and ointments. Glycerol has the preservative capacity, and also prevents the growth of bacteria.
Field of use
The scope of application of this product is wide and varied:
- food industry;
- the medicine;
- cryobiology;
- cosmetology;
- manufacturing candles;
- explosives;
- e-Sigs;
- detergents;
- packaging materials;
- agriculture (seed treatment);
- production of paper;
- processing leather products;
- Production freezing liquids (antifreeze);
- production of synthetic fabrics (silk and wool).
food processing industry
In this case, used to dissolve the Glycerol, thickening, emulsifying and maintain the necessary humidity during preparation of the bread-block products, cakes and chocolate, as well as some alcohol beverages. Note that for these purposes the product in 95% concentration, past a plurality of purification steps.
When the addition of glycerol in dough bread stale much more slowly. Chocolate tool prevents the appearance of a white plaque and adds sweetness. The pasta drug prevents sticking during cooking. And Glycerin softens the taste of alcohol.
Studies have proven preservative properties of glycerol. Means a concentration of 50% or higher increases the shelf life of meat and dairy products by 3 times, and blocks propagation of lactic acid bacteria.
The medicine
Glycerin is used to dissolve the active ingredients in certain medications, such as iodine, phenol, thymol, bromine, tannin and mercuric chloride. The highly concentrated drug solution glycerol is often replaced by water. With the help of this tool are more viscous formulations, tablets and retain needed moisture.
Glycerin is found in many ointments, because it prevents them drying out. In medicine, most of the drug is used for softening and moisturizing the skin and mucous membranes. Due to its exposed dry areas become soft and supple. However, in this case it is necessary to strictly adhere to the dosage necessary because a high concentration of active agent may produce the opposite effect.
Glycerin is also used as a laxative medicine at a certain concentration it irritates and stimulates bowel movements.
Cosmetology
Effective moisturizer that is included in most cosmetics for face and body. When applying creams containing glycerol, is formed on the skin very fine water-holding film which prevents evaporation of moisture.
Nourishing and moisturizing masks and creams, hair products, tonics and lotions - all these products is most often used glycerine. It is safe, non-toxic and does not cause allergies. However, in the manufacture of household cosmetic products based on this substance should be remembered that in pure glycerol can cause irritation and dryness. Cause the drug to the skin and mucous membranes can be at a concentration of less than 30%, in creams and tonics maximally 7% solution is used.
Glycerin is used to make extracts from plants belonging to the cosmetic and pharmaceuticals since it is non-toxic, resistant to high temperatures.
Glycerin is needed for the production of hair shampoos, shower gels and other detergent formulationsBecause along with moisturizing and softening properties of this versatile material increases foam and prevents the skin from drying.
Glycerin is also part of colorants for eyebrows, eyelashes and hair, preventing damage and drying skin peroxide and dyes.
E-Sigs
One component of the liquid for electronic cigarette is Glycerine, thanks to it vapor becomes more dense and saturated, and has a pleasant sweet taste.
Agriculture
Seed treatment glycerol prevents rot and fungal infections, and promotes successful germination.
Packaging materials
Glycerin is used as a plasticizer for the production of transparent materials for packaging, in particular cellophane. This contributes to the ductility, resistance to low temperatures. Derivatives of active substances are used for coating paper from which the bags are made for storing oil products.
Cryobiology
Recent research scientists have shown that it is possible to use glycerol at freezing cells and kriopreparatov. Thanks to its use of a 5% concentration, the preparations under freezing and thawing retain their osmotic properties.
conclusion
Glycerol and its derivatives - almost universal substance, bringing huge benefits and is widely used in many areas of our lives. They possess moisturizing, emollient, humectant, preservative, emulsifying and thickening properties.
Glycerin can be obtained in several ways: by saponification of fats chlorination of propylene at high temperatures hydrogenation of monosaccharides by hydrolysis of the resulting wood meal or starch. And also as a byproduct during the production of biofuels.
