Lithium 12-hydroxystearate (C 18 H 35 LiO 3) is a chemical compound classified as a lithium soap. In chemistry, "soap" refers to salts of fatty acids. Lithium 12-hydroxystearate is a white solid. Lithium soaps are key component of many lubricating greases.
Pellets of soda lye (sodium hydroxide) Pellets of potash lye (potassium hydroxide)Lye is a hydroxide, either sodium hydroxide or potassium hydroxide.The word lye most accurately refers to sodium hydroxide (NaOH), [citation needed] but historically has been conflated to include other alkali materials, most notably potassium hydroxide (KOH).
Pharmacokinetics is based on mathematical modeling that places great emphasis on the relationship between drug plasma concentration and the time elapsed since the drug's administration. Pharmacokinetics is the study of how an organism affects the drug, whereas pharmacodynamics (PD) is the study of
Some soap-makers leave the glycerol in the soap. Others precipitate the soap by salting it out with sodium chloride. Skeletal formula of stearin, a triglyceride that is converted by saponification with sodium hydroxide into glycerol and sodium stearate. Fat in a corpse converts into adipocere, often called "grave wax".

It is also the main component of soap scum, a white solid that forms when soap is mixed with hard water. Unlike soaps containing sodium and potassium, calcium stearate is insoluble in water and does not lather well. [2] Commercially it is sold as a 50% dispersion in water or as a spray dried powder.
Claims have been made in the media that antibacterial soap is more effective than plain soap in the prevention of the SARS-CoV-2 virus. The CDC and the Food and Drug Administration both recommend plain soap; there is no evidence that antibacterial soaps are any better, and limited evidence that they might be worse long-term. [10]
