Zinc chloride and calcium chloride, as well as potassium hydroxide and sodium hydroxide ( and many different salts ), are so hygroscopic that they readily dissolve in the water they absorb: This property is called deliquescence.

Urea acts as a keratolytic due to its hygroscopic property.

Also if the quality of the saltpeter was low ( for instance if it was contaminated with highly hygroscopic calcium nitrate ), or if the powder was simply old ( due to the mildly hygroscopic nature of potassium nitrate ), in humid weather it would need to be redried.

Black powder made with less-expensive and more plentiful sodium nitrate ( in appropriate proportions ) works just as well but is more hygroscopic than powders made from Potassium nitrate — popularly known as saltpeter.

In addition to being a nuisance, the residue from burnt black powder is hygroscopic and with the addition of moisture absorbed from the air, this residue forms a caustic substance.

* CaF < sub > 2 </ sub >( Eu ) or calcium fluoride doped with europium: The material is not hygroscopic, has a 940 ns decay time, and is relatively low-Z.

Some water-soluble flux residues are hygroscopic, which causes problems with electrical resistance and contributes to corrosion.

Tacky surfaces tend to accumulate dust and particulates, which causes issues with electrical resistance ; the particles themselves can be conductive or they can be hygroscopic or corrosive.

Mineral oil is not hygroscopic ( i. e., it will not absorb water from the air ), unlike standard brake fluid, so therefore gas bubbles do not form in the system, as would be the case with standard brake fluid, creating a ' spongy ' brake feel.

A common use for desiccators is to protect chemicals which are hygroscopic or which react with water from humidity.

Isoquinoline is a colorless hygroscopic liquid at room temperature with a penetrating, unpleasant odor.

Unlike the flaked mashed potatoes, both of the granulated and pearls will be more hygroscopic when it mixes with water.

A hygroscopic material will tend to become damp and " cake " when exposed to moist air ( such as salt in salt shakers during humid weather ).

They are both very hygroscopic ( i. e., damaged when exposed to moisture in the air ) but offer excellent light output and energy resolution ( 63 photons / keV γ for LaBr < sub > 3 </ sub >( Ce ) versus 38 photons / keV γ for NaI ( Tl )), a fast response ( 16 ns for LaBr < sub > 3 </ sub >( Ce ) versus 230 ns for NaI ( Tl )), excellent linearity, and a very stable light output over a wide range of temperatures.

Manufacturers claim a number of advantages for the fiber: about 50 % more hygroscopic ( water-absorbent ) per unit volume than cotton, takes dye like cotton, color-fast when washed in warm water, resistant to shrinkage and fading but prone to stretching and pilling.

Other products include laminaria ( made of dried seaweed ) or synthetic hygroscopic materials, which expand when placed in a moist environment.

Funaria hygrometrica is called “ cord moss ” because of the twisted seta which is very hygroscopic and untwists when moist.

The hydrochloride salt, triethylamine hydrochloride ( triethylammonium chloride ), is a colorless, odorless, and hygroscopic powder which decomposes when heated to 261 ° C.

Ozone glasses have excellent conformality but tend to be hygroscopic – that is, they absorb water from the air due to the incorporation of silanol ( Si-OH ) in the glass.

Porcelain crucibles are hygroscopic, i. e. they absorb a bit of weighable moisture from the air.

Desiccants should never be placed inside a canister of lye because lye has much stronger hygroscopic properties than activated carbon and silica gel ( the most common ingredients in commercial desiccant packets ) and will pull and absorb the water from the desiccant packets.

While not a new technique, hygroscopic seeding for enhancement of rainfall in warm clouds is enjoying a revival, based on some positive indications from research in South Africa, Mexico, and elsewhere.

These hygroscopic salt crystals will hold moisture from a humid atmosphere and cause rusting.

The product is naturally moist from the hygroscopic nature of the molasses and is often labelled as " soft.

It is produced also by enzymatic hydrolysis from gelatinated starch and is usually found as a creamy-white hygroscopic spraydried powder.

Ethanol is hygroscopic, meaning it will absorb water vapor directly from the atmosphere.

Methanol is hygroscopic, meaning it will absorb water vapor directly from the atmosphere.

Tyrkisk Peber is hygroscopic, and if left in an unsealed bag it will absorb water from the air and stick together after a few days.

Glycol-ether ( DOT 3, 4, and 5. 1 ) brake fluids are hygroscopic ( water absorbing ), which means they absorb moisture from the atmosphere under normal humidity levels.

The calcium / magnesium salts make unrefined sea salt hygroscopic ( i. e., it gradually absorbs moisture from air if stored uncovered ) and confer a faintly bitter overtone.

Trimethylammonium chloride is a hygroscopic colorless solid prepared from hydrochloric acid.

Champa incenses contain a semi-liquid resin, " halmaddi ," taken from the Ailanthus Malabarica tree, which gives them their characteristic grey color and damp texture: halmaddi is hygroscopic.

Drums containing FSII must be kept clean and dry, since the additive is hygroscopic and can absorb water directly from moisture in the air.

Fluids such as DOT 4 are hygroscopic and will absorb water from the atmosphere.

Fluids such as DOT 3 are hygroscopic and will absorb water from the atmosphere.

Polyethylene glycol fluids are hygroscopic and will absorb water from the atmosphere, which is necessary to prevent sheer and undiluted water in the braking system, which is very corrosive, also water droplets can freeze in the pipes, thus blocking the system.
