Options

A. Cellulose hypoxathate
B. Cellulose xanthate
C. Carboxymethyl cellulose
D. All the above.

Answer

To solve the question regarding the smoothening agent in ice creams and the brightening agent in detergents, we will analyze the options provided and identify the correct answer step by step.

### Step 1: Understand the Question
The question asks for a specific compound that serves as both a smoothening agent in ice creams and a brightening agent in detergents.

### Step 2: Review the Options
The options provided are:
1. Cellulose hypoxanthate
2. Cellulose xanthate
3. Carboxymethyl cellulose
4. All of the above

### Step 3: Analyze Each Option
- **Cellulose Hypoxanthate**: This is not commonly known for use in food products or detergents.
- **Cellulose Xanthate**: This is primarily used in the production of viscose rayon and not as a smoothening or brightening agent.
- **Carboxymethyl Cellulose (CMC)**: This is a derivative of cellulose that is known for its thickening and stabilizing properties. It is widely used in food products, including ice creams, to improve texture and smoothness. Additionally, it is used in detergents as a brightening agent.
- **All of the Above**: This option would only be correct if all previous options were valid, which they are not.

### Step 4: Conclusion
Based on the analysis, the correct answer is **Carboxymethyl Cellulose (Option 3)**, as it is specifically known for its role as a smoothening agent in ice creams and a brightening agent in detergents.

### Final Answer
The smoothening agent in ice creams and brightening agent in detergents is **Carboxymethyl Cellulose**.
