Certain chemicals such as cetyl alcohol (hexadecanol) and stearyl alcohol (octadecanol) form monomoiecular layers on a water surface. These layers, act as evaporation inhibitors by preventing .the water molecules to escape past them.

Chemical Emulsions to Minimize Water Loss

Chemical emulsions are mixtures of two or more immiscible liquids, stabilized by an emulsifying agent. These emulsions find various applications in different fields including construction, agriculture, and cosmetics. Some of the chemical emulsions that are used to minimize the loss of water through the process of evaporation are:

1. Methyl alcohol
2. Cetyl alcohol
3. Stearyl alcohol
4. Kerosene

Explanation

Out of the above-mentioned chemical emulsions, options 2 and 3 (cetyl alcohol and stearyl alcohol) are used as humectants in cosmetics and personal care products such as lotions, moisturizers, and lip balms. They are added to these products to retain moisture and prevent the loss of water through evaporation.

Option 4 (kerosene) is used as a carrier oil in pesticides and herbicides. It helps to spread the active ingredients evenly across the plant surface and prevents the loss of the active ingredients due to evaporation.

Option 1 (methyl alcohol) is not commonly used to minimize water loss through evaporation. It is a toxic substance and has limited applications in the industry.

Therefore, the correct answer is option D (2 and 3).
