Theory of the Stability of
Lyophobic Colloids
This chemistry classic offers an excellent, highly relevant account of the stability of lyophobic colloids and suspensions and develops a quantitative theory.
Evert Johannes Willem Verwey, J. Th. G. Overbeek, Jan Theodoor Gerard Overbeek, 1999
In lyophobic sols, the electric double- layer as well as the /eta potential of
disperse phase particles gets discharged by electrolyte ions bearing charges
opposite to their fixed charges. Lyophobic sol particles, being devoid of solvation
layers, ...

Essential Chemistry Xii
Lyophobic sols. The word lyophobic means solvent hating. Metals, their oxides
and sulphides etc. when simply mixed with the dispersion medium, say water, do
not form a colloidal sol. Special methods are employed to prepare their sols.

Remington: The Science and Practice of Pharmacy
Lyophobic dispersions are intrinsically unstable and irreversible because of the
lack of attraction between the dispersed and continuous phases. Unlike lyophilic
dispersions, their large surface free energy is not lowered by solvation, their ...

Competition Science Vision
Classification of Colloids Colloids are of two types : (a) Lyophilic colloids, (b)
Lyophobic colloids. (a) Lyophilic colloids — These are solvent loving and are
reversible. • Lyophilic sols have surface tension lower than that of dispersion
medium.

Foams: Theory: Measurements: Applications
This requires that the lyophilic groups be directed toward the liquid and the
lyophobic groups toward the gas phase. The chemical properties of lyophobic
and lyophilic groups and the type of solvent determine the direction and extent of
...

Sunscreens: Development: Evaluation, and Regulatory Aspects: ...
Those that are difficult to wet are termed lyophobic. When the suspension liquid
is water it is more common to refer to the terms hydrophilic and hydrophobic,
respectively. With lyophilic material there is an affinity between the material
surface ...

Biophysics & Biophysical Chemistry
(b) Dispersion colloids like the gold sol are lyophobic sols with no solvate
envelope around the disperse phase particles. (c) Rigid gels are formed by the
gelation of lyophilic sols. (d) In absence of the solvate envelope around their
particles, ...

albumin and gum Lyophobic sol-aluminium hydroxide, ferric hydroxide,
arsenious sulphide. (6) Study of the role of emulsifying agent in stabilizing the
emulsions ...

1 .3b Lyophobic Colloids Lyophobic colloids are known by a variety of terms,
depending on the nature of the phases involved. Some of these are listed in
Table 1.4. Some of the terms (e.g., aerosol, gel) are somewhat ambiguous, so the
reader ...
