Basic Information

Product Description

Product Name：Sodium Lauryl Sulfate  

CAS No: 151-21-3

Form:liquid

Product Application

(1) Personal Care Products (~30% share)

Toothpaste:​ Classic foaming agent (1%–3% of formula), rapidly generating rich foam to enhance the "clean feeling" during brushing (but gradually replaced by milder surfactants like sodium lauroyl sarcosinate due to strong irritation).

Shampoos (low-end products):​ As an auxiliary surfactant (3%–8% of formula) to boost foam volume, commonly found in cheap open-shelf shampoos (requires silicone oil to mitigate irritation).

Body Washes/Hand Soaps (industrial grade):​ Used in low-foam cleaning products or blended with SLES to reduce costs (ratio 1:5–1:10).

Facial Cleansers (soap-based blends):​ Blended with fatty acids (e.g., stearic acid) to form "soap-based-SLS" systems for enhanced cleaning power (only suitable for oily skin with high tolerance).

(2) Household Cleaning Products (~40% share)

Laundry Powders/Liquids:​ As the main surfactant (5%–15% of formula), with good low-temperature washing performance and rich, easy-rinsing foam (but high foam may cause overflow in washing machines, requiring defoamers).

Dishwashing Detergents (industrial grade):​ Used in hand dishwashing powders for rapid grease removal, but highly irritating to skin.

Hard Surface Cleaners:​ Blended with sodium carbonate and sodium metasilicate for degreasing kitchen stoves and bathroom tiles (requires mechanical friction).

(3) Industrial Fields (~30% share)

Textile Dyeing:​ Used as a penetrant (desizing/scouring), dispersant (dye grinding), and emulsifier (printing paste preparation).

Petroleum Extraction:​ As an oil displacement agent in tertiary oil recovery (reduces oil-water interfacial tension to improve recovery efficiency).

Pharmaceuticals & Biochemistry:

Pharmaceutical formulations: Used as a tablet disintegrant (promotes drug dissolution);

Laboratory reagent: As a denaturant for protein electrophoresis (breaks hydrogen bonds to linearize molecules).

Laboratory reagent: As a denaturant for protein electrophoresis (breaks hydrogen bonds to linearize molecules).

Storage

Store sealed in a cool (<30°C), dry, well-ventilated place; protect from moisture (hygroscopic, prone to caking).

Keep away from strong acids and oxidizers (e.g., potassium permanganate) to prevent decomposition.
