Which of the following statement about emulsions is true?a)Oily drugs ...
Emulsions
Emulsions are a type of colloid in which two immiscible liquids are mixed together to form a stable mixture. The mixture is made up of small droplets of one liquid dispersed throughout the other liquid. Emulsions can either be oil-in-water (O/W) or water-in-oil (W/O) depending on which liquid is dispersed and which one is the continuous phase.
Statement Analysis
a) Oily drugs cannot be prepared in the form of emulsions - This statement is false. Oily drugs can be prepared in the form of emulsions. In fact, many pharmaceutical products are formulated as emulsions to improve their stability, bioavailability, and ease of administration.
b) Digestion does not involve the process of emulsification - This statement is true. Digestion involves the breakdown of large molecules into smaller ones, but it does not involve the process of emulsification. However, emulsification does play a role in digestion as it helps to break down fats into smaller droplets that can be more easily digested by enzymes.
c) Disinfectants like Dettol and Lysol give emulsions of water-in-oil type on mixing with water - This statement is false. Disinfectants like Dettol and Lysol are typically made up of water-soluble compounds and do not form emulsions when mixed with water.
d) The cleansing action of soap is based upon the formation of water-in-oil emulsion - This statement is also false. The cleansing action of soap is based on the ability of soap molecules to form micelles, which are clusters of molecules that surround and trap dirt and oil. The hydrophobic tails of the soap molecules are attracted to the dirt and oil, while the hydrophilic heads face outward and are attracted to water, allowing the micelles to be easily rinsed away with water.
Conclusion
In summary, statement (b) is the only true statement regarding emulsions. Digestion does not involve the process of emulsification, although emulsification does play a role in the digestion of fats.

The digestion of fats in the intestines takes place by the process of emulsification. A small amount of the fat reacts with the alkaline solution present in the intestines to form a sodium soap.
