Sodium dodecyl sulfate Usage

Household cleaning, personal care, and cosmetics

Cleaning products—foaming agents (shampoo, shower gel, laundry detergent, etc.)—effectively remove oil and dirt
Oral care—detergents (toothpaste, mouthwash)—remove food debris and plaque
Cosmetics—emulsifiers (skin creams, lotions)—help stabilize the mixture of oil and water

Industrial applications

Textile industry—wetting agents, detergents, and dispersants—ensure uniform chemical penetration
Metalworking—industrial degreasers and cleaners

Pharmaceutical and laboratory applications

Ointments and lotions—Emulsifiers or wetting agents improve the dispersion and penetration of active ingredients
Ionic detergents—Suitable for protein denaturation in cell biology and biochemistry research

Food industry

Used as an emulsifier (e.g., in egg white products) and a foaming aid (e.g., in marshmallow production)
