Triacetin is the organic compound with the formula C 3 H 5 (OCOCH 3) 3. It is classified as a triglyceride , i.e., the triester of glycerol with acetic acid . [ 6 ] It is a colorless, viscous, and odorless liquid with a high boiling point and a low melting point.
Glycerol Triacetin, the simplest possible fat (triglyceride) after triformin. Glycerides, also known as acylglycerols, are esters formed from glycerol and fatty acids, and are generally very hydrophobic. [1] Glycerol has three hydroxyl functional groups, which can be esterified with one, two, or three fatty acids to form mono-, di-, and ...

The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

Cellulose acetate phthalate is commonly plasticized with diethyl phthalate, a hydrophobic compound, or triethyl citrate, a hydrophilic compound; other compatible plasticizers are various phthalates, triacetin, dibutyl tartrate, glycerol, propylene glycol, tripropionin, triacetin citrate, acetylated monoglycerides, etc.
Together with cholesterol and ceramides, free fatty acids form a water-impermeable barrier that prevents evaporative water loss. [38] Generally, the epidermal lipid matrix is composed of an equimolar mixture of ceramides (about 50% by weight), cholesterol (25%), and free fatty acids (15%). [ 38 ]
Stearin is obtained from animal fats created as a byproduct of processing beef.It can also be found in tropical plants such as palm. It can be partially purified by dry fractionation by pressing tallow or other fatty mixtures, leading to separation of the higher melting stearin-rich material from the liquid, which is typically enriched in fats derived from oleic acid.
