Sodium Dodecyl Benzene Sulfonate (SDBS) CAS 25155-30-0
Sinochem is a leading global Sodium Dodecyl Benzene Sulfonate (SDBS) manufacturer and supplier. Backed by advanced spray-drying technology and a dedicated team of chemical experts, we deliver high-performance Linear Alkylbenzene Sulfonate Sodium (LAS-Na) tailored for diverse industrial and commercial formulation needs.
Sodium Dodecyl Benzene Sulfonate is a high-content anionic surfactant presenting as a white to light-yellow powder or granule. Highly soluble in water, SDBS exhibits exceptional performance in detergency, wetting, foaming, emulsification, and dispersion, making it a cornerstone ingredient in the global surfactant market.
- Superior Detergency & Grease Removal: SDBS significantly lowers surface tension, providing outstanding wetting and emulsifying action to effectively remove stubborn oils, heavy grease, and particulate soils.
- Excellent Water Solubility & Stability: It dissolves readily in water to form clear or translucent solutions. It maintains excellent chemical stability across wide temperature ranges and exhibits strong resistance to hard water.
- High Biodegradability: As a linear alkylbenzene sulfonate, our SDBS features a high biodegradation rate (> 90%), minimizing environmental accumulation and aligning with modern eco-friendly chemical mandates.
Sodium dodecyl benzene sulfonate Description
NAME: Sodium dodecyl benzene sulfonate (SDBS)
Synonyms: Linear Alkylbenzene Sulfonate Sodium / Dodecyl Benzene Sulphonic Acid Sodium Salt / LAS-Na
Molecular Formula: C18H29NaO3S
Molecular Weight: 349.5
CAS NO.: 25155-30-0
Density: 1.02 g/cm3
Appearance: Free-flowing white or light-yellow powder / granule.
Solubility: Soluble in water. The base aqueous solution is easy to bubble, but the viscosity is low, and easy to disappear, and has better permeability and deterring power.
Properties: Solutions readily generate rich, stable foam with strong permeability. It acts as an excellent alkaline-stable cleaning agent.
Storage: Store in a tightly sealed container within a cool, dry, and well-ventilated area. Keep away from moisture and direct sunlight to prevent caking.
Safety Protection: Irritating to mucous membranes and upper respiratory tract, irritating to eyes and skin. May cause allergic reactions in the respiratory system.
About Us: With over many years as a certified Sodium dodecyl benzene sulfonate manufacturer, we combine innovation with stringent production standards to deliver high-performance product.

Linear Alkylbenzene Sulfonate Sodium Applications
- Daily Chemical & Household Care: The core cleaning ingredient in laundry powders, heavy-duty liquid detergents, dishwashing liquids, and household scouring agents.
- Textile & Leather Processing: Utilized as an efficient scouring agent, wetting agent, and dyeing auxiliary to ensure uniform color distribution and deep fiber penetration.
- Metal Treatment & Electroplating: Serves as a highly effective degreasing and cleaning agent prior to metal plating or surface coating.
- Paper & Pulp Industry: Acts as a powerful de-inking agent for recycled paper processing, facilitating the separation of ink from cellulose fibers.
Frequently Asked Questions (FAQ)
Q1: What is the difference between SDBS and LAS?
A: They refer to the same primary chemical substance. SDBS (Sodium Dodecyl Benzene Sulfonate) is the specific chemical name highlighting the 12-carbon chain, while LAS (Linear Alkylbenzene Sulfonate) is the broader industrial category name for this class of biodegradable linear anionic surfactants.
Q2: What are the common functional equivalents to SDBS CAS 25155-30-0?
A: In global formulations, SDBS can often replace or complement brand-name surfactants such as Nacconol 90G, Calimulse EM-96F, and Ufaryl DL 90C due to equivalent active matter content and performance metrics.
Q3: Is SDBS safe for use in consumer eco-friendly products?
A: Yes. Unlike branched alkylbenzene sulfonates, our modern Linear Alkylbenzene Sulfonate (LAS) features a straight carbon chain that allows fast microbial breakdown. With a biodegradability rate exceeding 90%, it meets international standard green criteria for eco-conscious detergents.
