Stearin
Also known as tristearin, tristearoyl-sn-glycerol, Stearic acid triglycerin ester, Trioctadecanoin, TG(18:0/18:0/18:0), 2,3-di(octadecanoyloxy)propyl octadecanoate
Stearin , or tristearin, or glyceryl tristearate is an odourless, white powder. It is a triglyceride derived from three units of stearic acid.
