Etymology: "Glycerins" is simply the plural of "glycerin," so the substance it names is the one that matters. Glycerin is a sweet, colourless, syrupy liquid, and the name comes from the Greek "glykys," meaning sweet, the same root behind "glucose." Its chemical form is a three-carbon alcohol, which is why it is often called glycerol in technical contexts. The plural form is used when people speak of several distinct glycerins, or of multiple products and preparations that contain them, rather than of the single pure substance.
