Detergents often contain

Options

A. Bleach
B. Fluorescers
C. Perborates
D. All the above

Answer

**Step-by-Step Solution:**

1. **Understanding Detergents**: Detergents are surfactants that help in cleaning by lowering the surface tension of water. They are amphipathic molecules, meaning they have both hydrophilic (water-attracting) and lipophilic (fat-attracting) parts.

2. **Components of Detergents**:
- **Hydrophilic Head**: This part of the molecule is polar or charged, which allows it to interact with water.
- **Lipophilic Tail**: This part consists of long hydrocarbon chains that attract oils and fats, helping to lift dirt and grease from surfaces.

3. **Additional Ingredients**:
- **Bleach**: Detergents often contain bleach to enhance the whitening of clothes. Bleach helps to remove stains and makes fabrics appear brighter.
- **Optical Brighteners**: These substances are added to make clothes appear shinier and whiter. They absorb ultraviolet light and re-emit it as visible blue light, which makes the fabric look brighter.
- **Perborates**: These are oxidizing agents included in detergents for their effective cleaning properties. They help in breaking down stains and enhancing the overall cleaning action.

4. **Conclusion**: Detergents typically contain a combination of surfactants, bleach, optical brighteners, and oxidizing agents like perborates to effectively clean and brighten fabrics.

**Final Answer**: Detergents often contain surfactants, bleach, optical brightening agents, and oxidizing agents.
