Glycerol is not used in

Options

A. Explosive making
B. Shaving soap making
C. As an antifreeze for water
D. As an antiseptic agent

Answer

To determine which application glycerol is not used for, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understanding Glycerol**:
- Glycerol, also known as glycerin, has the chemical formula C3H8O3. Its structure consists of three hydroxyl (–OH) groups, making it a triol.

2. **Option Analysis**:
- **Option 1: Explosive Making**:
- Glycerol can be converted into nitroglycerin, which is a well-known explosive. Therefore, glycerol is indeed used in explosive making.

- **Option 2: Shaving Soap Making**:
- Glycerol has moisturizing properties and is often included in soaps, including shaving soaps, due to its ability to provide a smooth application and reduce irritation. Thus, glycerol is used in shaving soap making.

- **Option 3: As an Antifreeze for Water**:
- Glycerol is used as an antifreeze because it lowers the freezing point of water and disrupts ice formation. Therefore, glycerol is used as an antifreeze for water.

- **Option 4: As an Antiseptic Agent**:
- While glycerol has some antimicrobial properties, it is not commonly used as a primary antiseptic agent. Other substances are preferred for antiseptic purposes. Thus, glycerol is not used as an antiseptic agent.

3. **Conclusion**:
- After analyzing all the options, we conclude that glycerol is not used as an antiseptic agent. Therefore, the correct answer is **Option 4**.

### Final Answer:
Glycerol is not used as an antiseptic agent.
