water-hating, as opposed to hydrophilic, or water-loving. Our DriClime® underwear, for example, is largely hydrophobic, since its mission is to pass sweat away from your skin and then have it evaporate. We avoid hydrophilic yarn because it gets soggy, and thus heavy and cold.
(Greek, hydro = water + phobos = fear) Avoiding associations with water; nonpolar.
Water-repellant. That property of a substrate (e.g., the image part of a lithographic plate), which causes it to repel water and permit an oil-based ink to adhere. The opposite of hydrophilic. See HYDROPHILIC
having little affinity for water; nonwettable.
Means water insoluble and refers to non-polar properties as opposed to polar properties of water. Water soluble, or hydrophilic, molecules do not easily mix with hydrophobic molecules or solutions. Oil is a hydrophobic substance and mixtures of oily and watery molecules tend to minimize their contact surface. Thus the observed separation of oil from water when left standing. However, oil can be partially mixed with water when shaking a container vigorously indicating that the separation or mixing of molecules is determined by the energy of molecular interaction. The energy to overcome these molecular interactions can be provided by mechanical force (shaking) or high temperature. The latter is a well known observation; salts, sugars, and fats normally mix better in hot than cold water, and hot water is better in removing stains form dishes or cloths.
insoluble in water, not readily absorbing moisture, or being adversely affected by water; either incompatible with water or having little affinity for it; often, such molecules are hydrocarbons.
not capable of uniting with or taking up water.
Used to describe water-repellent characteristics of shell fabric, and moisture management or push-pull qualities of underwear fabric.
of, relating to, or having a lack of affinity for water; resistant to wetting
Literally: “fear of water.” Synonymous with lipophilic. Can be used to describe substances that are not water soluble. Most drugs are hydrophobic(lipophilic), and are converted to water-soluble hydrophilic metabolites by biotransforming enzymes.
aversion to water; a hydrophobic surface will not allow large puddles of water, but rather will form droplets. These surfaces are often termed "de-wetted."
"water fearing". Hydrophobic compounds do not dissolve easily in water, and are usually non-polar. Oils and other long hydrocarbons are hydrophobic.
Having a reluctance to mix with water; usually nonpolar molecules. The fatty acids that form the interior pocket between the two layers of the cell membrane are hydrophobic.
Literally, water-hating. Describes nonpolar groups that repel water molecules.
Chemistry. Relating to or being a hydrophobe; repelling water. Biology. not tolerant of water or a wet environment. Medicine. of or relating to rabies. Psychology. of or relating to hydrophobia.
hydrophobicity; hydrophobic group. A nonpolar molecule or group that has little affinity for water. Hydrophobic groups on molecules in solution tend to turn in on themselves or clump together with other hydrophobic groups because they are unable to disrupt the network of strong hydrogen bonds in the water around them.
Hydrophobic is antagonistic to water, incapable of dissolving in vater. This property is characteristic of oill, fats, waxes, and many resins.
water-hating, repels water.
"water-hating"; refers both to stationary phases that are not compatible with water and to molecules in general that have little affinity for water. Hydrophobic molecules have few polar functional groups; most are hydrocarbons or have high hydrocarbon content.
A qualitative term referring to the water-avoiding nature of a species. A functional group of a molecule that is not very water-soluble is referred to as a hydrophobe.
Capable of repelling water.
Non-wetting; water repelling.
describes fibres such as polyester that absorb little moisture and occasionally even repel it.
Iiterally "water-fearing"; refers to substances that associate more readily with oily substances than with water.
Nonpolar molecule or part of a molecule that cannot form favorable bonding interactions with water molecules and therefore does not dissolve in water. (Literally, "water hating.")
Fearing water. An amino acid residue with an aliphatic or aromatic side chain, such as phenylalanine, that cannot bond with water.
The word hydrophobic can be broken into is two halves- hydro- which means water, and phobic- which means afraid. A hydrophobic amino acid is one which does not like to be near water. It avoids water by associating with other hydrophobic amino acids. Hydrophobic amino acids do not have charges. Hydrophilic amino acids (philic- means love) do like to be associated with water, and do have charges. An example of a hydrophilic amino acid is glutamate.
Not compatible with water: will not absorb or mix with water.
abnormally afraid of water
A substrate that does not readily absorb water
(Hydro = water; Phobia = fear) molecules and amino acid side chains, mainly hydrocarbons, which are attracted to one another and reluctant to mix with water.
a molecule that does not like water.
Lacking affinity for water, or failing to adsorb or absorb water.
Water hating -- plastic for example.
nonpolar compounds that do not dissolve in water, such as oil, and are considered "water-hating"
Literally means "water hating". This describes a molecule or part of a molecule that prefers to be in an environment where there is no water. It means repelling, tending not to combine with, or incapable of dissolving in water.
Substance which does not absorb or exhibit affinity for water; not wettable. Also, lipophilic.
"Water hating". Those functional groups or molecules which prefer to be in an environment where there is no water; an oily environment.
Literally meaning is “water fearing.” The term indicates insolubility in water.
having the characteristic of repelling water (example: Teflon is a hydrophobic material.)
Water hating or having a strong aversion to water.
Water-hating. Refers to substances that cannot dissolve in water, such as fats or waxes.
Not capable of dissolving in water. Oil is a hydrophobic substance. The term is also used in association with rabies, where an infected animal will show aversion to water.
An aversion to water. A hydrophobic surface is one that will not support pools of water. The water is pulled into droplets on the surface of the hydrophobic material.
Water Hating. Most synthetic fibers, including polypropylene, repel rather than absorb water. A treatment can be added to polypropylene fibers to enable them to be just the opposite, or water loving (hydrophilic).
A term that describes substances which repel water.
A qualitative term referring to the water-avoiding nature of a functional group or molecule. A hydrophobic group or molecule also may be described as fat- or lipid-loving.
Materials which repel or resist water. Used when moisture is definitely an issue. These water resistant films can be used in applications such as anti-fog and products where water is detrimental to the efficient functioning of a process.
means water disliking, or water repelling.
Water repellent, as in the printing areas of an offset litho plate.
tending not to combine with water, or incapable of dissolving in water; insoluble or immiscible in water. A property exhibited by non-polar organic compounds, including the petroleum hydrocarbons.

water repellant; denotes a molecule consisting of water insoluble group(s) or a surface which is non-wettable by water; see also lipophilic
Gr. hydro: water + phobia: fear] • Molecules and amino acid side chains, which are mainly hydrocarbons (compounds of C and H with no charged groups or polar groups), have a lower energy when they are clustered together than when they are distributed through an aqueous solution. Because of their attraction for one another and their reluctance to mix with water they are called "hydrophobic." Oil is a hydrophobic substance; phenylalanine is a hydrophobic animo acid in a protein. (Contrast with hydrophilic.)
Water hating, the tendency of a surface not to wet with water.
the property of having no attractive interactions with water. Hydrophobic substances are nonpolar.
