What is Detergent?
A surfactant or mixture of surfactants with cleansing properties. Detergents contain both hydrophilic (water-loving) and hydrophobic (water-repelling) portions, allowing them to emulsify oils and lift dirt from surfaces. Unlike soaps, synthetic detergents work in hard water.

Frequently Asked Questions
A surfactant or mixture of surfactants with cleansing properties. Detergents contain both hydrophilic (water-loving) and hydrophobic (water-repelling) portions, allowing them to emulsify oils and lift dirt from surfaces. Unlike soaps, synthetic detergents work in hard water.
Detergents are used in laundry, dishwashing, industrial cleaning, personal care products, food processing sanitation, and as emulsifiers in biochemistry (SDS-PAGE). Cationic detergents (quaternary ammonium compounds) are used as disinfectants. Detergents are critical in oil spill bioremediation.
Concentrated liquid detergents are irritants to skin, eyes, and mucous membranes. Some detergents (particularly cationic types) are harmful if ingested. Detergent surfactants are toxic to aquatic organisms; biodegradability assessment is mandatory under REACH regulations.
The formula or notation for Detergent is: Surfactant structure: R-SO₄⁻Na⁺ (anionic) or R-N⁺(CH₃)₃ (cationic)
