Many technological process require

control of liquid spreading over solid

surface . When a drop is placed on a

surface, it can completely wet,

partially wet, or not wet the surface.

By reducing the surface tension with

sarfactants i.e ALTRANOL a non-

wetting material can be made to

become partailly or completely

wetting.

Fig.-1 – Surface tensionFig.-2 Non-ionic surfactants

Surfactants are also referred to as wetting agents & foamers. Surfactants lower the Surface tension of the medium in which it is dissolved. (as shown in Fig-1). By lowering this Interfacial tension between two media or interfaces(e.g. air/water, water/stain, stain/fabric)The surfactant plays a key role in the removal & suspension of dirt. The lower surfaceTension of the water makes it easier to lift dirt & grease off of clothes & other surfaces & help to keep them suspended in the dirty water. The water-loveing or hydrophilic headremains in the water & it pulls the stain towards the water, away from the fabric. The Surfactant molecules surround the stain particles, break them up & force them away fromthe surface of the fabric. They then suspend the stain particles in the wash water to remove them.Non-ionic surfactants do not have an electric charge which makes them resistant to water hard deactivation. They are excellent stain removers. Non-ionic serfactants contribute to making the surfactant system less hardness sensitive.

EMULSION

The immiscible water phase acts as an ion sink for the charged species in the Oily solvent. Ions from the oil strongly partition into the higher dielectric constantWater phase. Ion drainage & self charging through preferential partitioning areIntrinsic properties of oil water mixture.

ALTRANOL stable to metal salts & hard water.

Hard water includes the multivalent cations which can cause water to

form scales & resistance to soap & produces white precipitate. But

ALTRANOL treated fabric is stable with hard water & metal salts ,

& has very good wetting & detergency action with extremely hard water.

Since the ALTRANOL does

not have any ionic groups it

Does not react with hard

water ions. In addition

non-ionic detergents foam

less than ionic detergents,

which makes them resistant to water hard

deactivation. They are excellent grease removers.

ALTRANOL possess surface active properties

in water & whose solution are therfore to wet

surface that normally water repellent, thereby assisting in the mechanical dispersion

& emulsification of fatty or oily material & other substances that soil the surface.
