Super hygroscopic polymer films composed of biomass and hygroscopic salts are able to condense moisture from atmospheric humidity. [16] By implementing rapid sorption-desorption kinetics and operating 14–24 cycles per day, this technique produced an equivalent water yield of 5.8–13.3 L kg −1 of sustainable raw materials, demonstrating the ...
[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 ...
Primary efflorescence is named such, as it typically occurs during the initial cure of a cementitious product. It often occurs on masonry construction, particularly brick, as well as some firestop mortars, when water moving through a wall or other structure, or water being driven out as a result of the heat of hydration as cement stone is being formed, brings salts to the surface that are not ...
In 2005–06, potassium dichromate was the 11th-most-prevalent allergen in patch tests (4.8%). [ 12 ] Potassium dichromate is one of the most common causes of chromium dermatitis ; [ 13 ] chromium is highly likely to induce sensitization leading to dermatitis, especially of the hand and forearms, which is chronic and difficult to treat.
A general list of deliquescent substances. Pages in category "Deliquescent materials" The following 40 pages are in this category, out of 40 total.
One might consider two hygroscopic salts in a sealed chamber; the more hygroscopic one would dessicate the other. A comprehensive article would rank "deliquescent" substances by their critical humidity.--Polymath07 19:34, 7 July 2006 (UTC) Good point. Let's merge them and add an explanation of that. —Keenan Pepper 02:04, 8 July 2006 (UTC)
4 and two molecules of water of crystallization. [8] This species dissolves readily in water and alcohol. The anhydrous salt is hygroscopic and the hexahydrate is deliquescent. [citation needed] The dihydrate, CoCl 2 (H 2 O) 2, is a coordination polymer. Each Co center is coordinated to four doubly bridging chloride ligands.
