Question

Dettol foam emulsion in water. How this is stabilised?

Answer 1

Explanation:

Emulsion can be stabilized by increasing the repulsion between the dispersed phase i.e., by increasing the electrostatic repulsion (which is long range) or steric repulsion (short range). Emulsifiers are amphiphiles that reduce the interfacial tension between the two phases and contribute to the stabilization of dispersed droplets with electrostatic or steric effects.

I wish to know the detailed mechanism by which emulsifiers stabilize an emulsion. References will be of real help.

Thanks.

Answer 2

Dettol foam emulsion in water is stabilised by adding emulsifier like gelatin ,starch ,soap etc

Explanation:

Emulsion

It is the type of colloid in which liquid and liquid is mixed together or we can say that disperse phase and dispersion medium both are liquids .

Emulsion types :

• Water in oil
• Oil in water

water in oil

It is that in which dispersed phase is water and dispersion medium is oil .

example : butter ,cold cream etc

Oil in water

It is that in which the dispersed phase is oil and dispersion medium is water .

Example : Milk , vanishing cream etc

The unstable emulsions can be stabilized by adding emulsifier .

Emulsifier

It is the substance that prevent coagulation .

example : Gelatin , starch etc
