Glycerin (Glycerin) is a three factor alcohol soluble in water, but is extremely soluble in ethanol and other organic solvents. Glycerol is sweet, clear, colorless, sticky and sticky, and in the presence of heat and pouring material (such as HSO_4K), water is lost to bad smell aldehyde, which severely aggravate mucus. Creating acrolein with this profile is a way to detect glycerol. Glycerol has 3 hydroxyl groups that are responsible for solubility in water.
Glycerol is more naturally combined with fatty acids that make fat. For example, a glycerol molecule with 1 or 3 fatty acid monoglycerides or triglycerides, such as vegetable oil, and the like.
Glycerin is a topical dermatologist in the treatment category, and its forms are lotion and suppository.
