B. Cationic detergent -Household work and in toothpaste
C. Non-ionic detergent -Liquid diswashing
D. All of these

Answer

To determine which option is correctly matched regarding the use of different types of detergents and conditioners, let's analyze each option step by step:

### Step 1: Analyze the first option - Anionic hair conditioners
- Anionic detergents are negatively charged and are typically not used as hair conditioners. Instead, cationic detergents, which are positively charged, are used for this purpose because they can neutralize the negative charge on hair, reducing static and making it smoother.
- **Conclusion**: This option is incorrect.

### Step 2: Analyze the second option - Cationic detergent used in household work and in toothpaste
- Cationic detergents are positively charged and are generally not used in household cleaning and toothpaste. Instead, anionic detergents are commonly used for these applications due to their effective cleaning properties.
- **Conclusion**: This option is incorrect.

### Step 3: Analyze the third option - Non-ionic detergent used in liquid dishwashing
- Non-ionic detergents do not carry any charge and are effective in removing grease and oil without reacting with hard water. They are indeed used in liquid dishwashing products.
- **Conclusion**: This option is correct.

### Step 4: Analyze the fourth option - All of these
- Since the first two options are incorrect and only the third option is correct, this statement cannot be true.
- **Conclusion**: This option is incorrect.

### Final Answer
The only correctly matched option regarding the use is:
**Third option: Non-ionic detergent used in liquid dishwashing.**
