Technical Document

Brief Overview
SLS Needle 94% is a high-quality anionic surfactant widely used in the chemical and detergent industries. It is a white, needle-shaped powder and is ideal for creating foamy cleansers like shampoos and detergents. This anionic surfactant is known for its high foaming and wetting properties, can tolerate some water hardness, and is biodegradable, ensuring consistent foaming performance.

Manufacturing Process
SLS is synthesized by treating lauryl alcohol with sulfur trioxide gas, oleum, or chlorosulfuric acid to produce hydrogen lauryl sulfate. The industrially practiced method typically uses sulfur trioxide gas. The resulting product is then neutralized through the addition of sodium hydroxide or sodium carbonate. Lauryl alcohol is in turn usually derived from either coconut or palm kernel oil by hydrolysis, which liberates their fatty acids, followed by hydrogenation.
Due to this synthesis method, commercial samples of SLS are often a mixture of other alkyl sulfates, dodecyl sulfate being the main component. SLS is available commercially in powder and pellet forms. It seems the pellet form dissolves faster than the powder form in water.

Cleaning products:
Used in various cleaning products, such as dishwashing liquids, laundry detergents, and all-purpose cleaners. It helps to remove dirt and stains from surfaces and create a rich lather.

Toothpaste
Widely used in the toothpaste industry as a foaming agent and emulsifier. It helps to create a rich lather and improve the cleaning performance of toothpaste.

Shampoo
Commonly used in shampoos as a primary surfactant. It helps to remove dirt and oil from hair and scalp, and create a rich lather.
