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 ...
A constant blood concentration of 1 to 1.5 g/L (corresponding to 0.5 to 0.75 mg/L in the breath) should be maintained to acceptably saturate the enzyme. An initial dose of 0.6 to 0.7 g ethanol per kilogram body weight should be given (about 0.8 mL/kg or 0.013 fl.oz /lb).
Cgingold 04:04, 1 November 2006 (UTC) I have added a reference to the list of hygroscopic substances which looks to be the source of most of the original list. I have removed Diesel Fuel from the list of hygroscopic substances. Disel Fuel as per ASTM standard is allowed 200mg water per 1kg of fuel [1]. This is a tiny amount, indeed large ...
A humectant / h juː ˈ m ɛ k t ən t / is a hygroscopic (water-absorbing) substance used to keep things moist. They are used in many products, including food, cosmetics, medicines and pesticides. When used as a food additive, a humectant has the effect of keeping moisture in the food. [1]
Also, capsules that contain liquid or oil may deteriorate more quickly than those that don’t. Is it safe to take expired vitamins? Taking expired vitamins is generally considered safe—but ...
[1] Its p K a value in water cannot be accurately determined but in acetonitrile it has been estimated as −0.10 and in 1,2-dichloroethane −12.3 (relative to the p K a value of 2,4,6-trinitrophenol ( picric acid ), anchored to zero to crudely approximate the aqueous p K a scale [ 2 ] ), making it more acidic than triflic acid (p K a MeCN = 0 ...

It is a white, hygroscopic crystalline powder. It is odorless with a saline taste. It contains 38.28% potassium by mass. In the monohydrate form, it is highly hygroscopic and deliquescent. As a food additive, potassium citrate is used to regulate acidity, and is known as E number E332.
