Polyethylene glycols are used in the preparation of which type of detergent ?

Options

A. Cationic detergents
B. Anionic detergents
C. Non-ionic detergents
D. Soaps

Explanation

**Step-by-Step Solution:**

1. **Understanding Polyethylene Glycols (PEG):**
Polyethylene glycols are polymers made from ethylene glycol. They have various applications in different fields, including pharmaceuticals, cosmetics, and detergents.

2. **Types of Detergents:**
Detergents can be classified into three main categories:
- **Cationic Detergents:** These detergents carry a positive charge and are often used in fabric softeners and disinfectants.
- **Anionic Detergents:** These detergents carry a negative charge and are commonly used in household cleaning products.
- **Non-Ionic Detergents:** These detergents do not carry any charge and are often used in applications where mildness is required, such as in personal care products.

3. **Identifying the Correct Type of Detergent:**
The question specifically asks about the type of detergent that polyethylene glycols are used to prepare.

4. **Chemical Properties of PEG:**
Polyethylene glycols contain hydroxyl (–OH) groups, which are reactive and contribute to the formation of non-ionic detergents.

5. **Formation of Non-Ionic Detergents:**
Non-ionic detergents are typically formed by the reaction of polyethylene glycol with fatty acids, such as stearic acid. The resulting compounds are esters that do not carry any ionic charge.

6. **Conclusion:**
Based on the properties and reactions of polyethylene glycols, we conclude that they are used in the preparation of non-ionic detergents.

**Final Answer:**
Polyethylene glycols are used in the preparation of **non-ionic detergents**.
