C. Medicated soap
D. Toilet soap

Answer

To answer the question regarding the type of soap made by dissolving soap in ethanol and then evaporating the excess solvent, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Soaps**:
- Soaps are typically made from fats and oils or their fatty acids. They are the sodium or potassium salts of fatty acids and are produced through a process called saponification, which involves treating fats or oils with a strong alkali.

2. **Transparent Soap**:
- Transparent soaps are a specific type of soap that is created by dissolving regular soap in ethanol (alcohol) and then evaporating the excess solvent. This process allows the soap to become clear or transparent.

3. **Ethanol's Role**:
- Ethanol acts as a solvent in this process. It helps to dissolve the soap, making it easier to manipulate and mold into the desired shape. However, it is important to note that ethanol does not make the soap invisible; rather, it helps achieve a transparent appearance.

4. **Conclusion**:
- Based on the explanation, the correct answer to the question is that the soaps made by dissolving soap in ethanol and evaporating the excess solvent are known as **transparent soaps**.

### Final Answer:
**Transparent Soap**
