C. Disinfectants are antimicrobial drugs.
D. Antiseptic medicines can be ingested.

Explanation

To determine which statement is not correct among the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Statement 1**: "Some antiseptics can be added to soaps."
- This statement is correct. For example, triclosan is an antiseptic that is commonly added to soaps to enhance their antimicrobial properties.

2. **Analyze Statement 2**: "Dilute solutions of some disinfectants can be used as antiseptics."
- This statement is also correct. For instance, phenol at a 1% concentration acts as a disinfectant, while a 0.2% solution of phenol can be used as an antiseptic.

3. **Analyze Statement 3**: "Disinfectants are anti-microbial drugs."
- This statement is correct. Disinfectants are indeed antimicrobial agents used to kill or inhibit the growth of microbes on non-living surfaces.

4. **Analyze Statement 4**: "Antiseptic medicines can be ingested."
- This statement is incorrect. Antiseptics are meant for application on living tissues (like wounds) and are not intended for ingestion. They are not safe to consume as they can be harmful if taken internally.

### Conclusion:
After analyzing all the statements, we find that the incorrect statement is **Statement 4**: "Antiseptic medicines can be ingested."

### Final Answer:
The answer is **Option 4**.
