What are Detergents?

Detergents are cleaning agents that help remove dirt, grease, and stains from surfaces. They work by breaking down dirt and making it easier to wash away with water. Detergents are different from soap because they work well in both hard and soft water.

Types of Detergents

Liquid Detergents:

• Easy to dissolve in water
• Good for pre-treating stains
• Gentle on fabrics

Powder Detergents:

• More economical

• Last longer than liquid forms

Specialized Detergents:

• Dish washing detergents
• Floor cleaning detergents
• Laundry detergents
