The hygroscopic bending of involucral bracts surrounding a capitulum contributes to flower protection and pollination [21] and assists dispersion by protecting delicate pappi filaments from entanglement or destruction by precipitation, [22] e.g. Taraxacum (dandelions). In nature these involucral bracts have a diurnal rhythm.
It is a crystalline compound, but is hygroscopic to the point of being deliquescent. Owing to its very high acidity and good compatibility with organic solvents it has been employed as a catalyst in a wide range of chemical reactions. [1]

[2] [3] This is the opposite use of a hygroscopic material where it is used as a desiccant used to draw moisture away. In pharmaceuticals and cosmetics, humectants can be used in topical dosage forms to increase the solubility of a chemical compound's active ingredients , increasing the active ingredients' ability to penetrate skin, or its ...
Cobalt(II) chloride is an inorganic compound, a salt of cobalt and chlorine, with the formula CoCl 2.The compound forms several hydrates CoCl 2 ·n H 2 O, for n = 1, 2, 6, and 9. . Claims of the formation of tri- and tetrahydrates have not been confirmed
If biodiesel is indeed hygroscopic-- meaning that it has a strong tendency to pull water molecules out of the atmosphere -- there are serious implications in terms of its use, storage, etc., which would need to be addressed in the article. Currently, the problem of "Water contamination" is stated to arise because "Some of the water present is ...
Piperazine (/ p aɪ ˈ p ɛr ə z iː n /) is an organic compound that consists of a six-membered ring containing two nitrogen atoms at opposite positions in the ring. [3] Piperazine exists as small alkaline deliquescent crystals with a saline taste.
Potassium carbonate is the inorganic compound with the formula K 2 C O 3.It is a white salt, which is soluble in water and forms a strongly alkaline solution. It is deliquescent, often appearing as a damp or wet solid.
