Glycerin is a thick, colorless liquid that has a sweetish taste. This liquid has a high boiling point, and during heating, glycerin turns into a paste. In most cases, glycerin is used to make soaps, as well as other cosmetics, such as lotions, gels. You should also pay attention to the fact that this substance in the form of nitroglycerin is used for the manufacture of dynamite. Below it will be possible to familiarize yourself with the main physical indicators, as well as with the density of glycerol.
Physical properties
The physical properties of glycerol include dynamic viscosity, density, specific heat, and thermal conductivity. In addition, it should be noted that the physical properties of glycerol and the density of this substance will depend on temperature. However, most of all the temperature affects the viscosity of glycerol, which when heated can decrease by 280 times.
Glycerol density
The density of this substance will also depend on air temperature, but much less than, for example, viscosity. During heating to 100 degrees, the density of glycerol is reduced by only 6%. In normal condition, at a temperature of 20 degrees, the density of this substance is 1260 kg per cubic meter. During heating to 100 degrees, the density of glycerin increases already to 1208 kg per cubic meter.
Thermal conductivity of glycerol
We have examined the density indicators of this substance. However, speaking of physical properties, one should also mention not only the density of glycerol, but also its thermal conductivity. At a temperature of about 25 degrees, the thermal conductivity of the described substance is 0.279 W / (m * deg), which is half the thermal conductivity of ordinary water.
In the manufacture of any cosmetic products, these indicators simply need to be taken into account.
