What is Sodium Lauryl Sulfate?
Sodium Lauryl Sulfate (SLS) is an anionic surfactant consisting of a hydrophobic alkyl chain and a hydrophilic sulfate group. This structure allows SLS to reduce surface tension and improve the interaction between water and oils, dirt, or other substances.
SLS is widely used as a detergent, foaming agent, wetting agent, emulsifier, and dispersant. Its strong surface-active properties make it suitable for a broad range of formulations, from personal care and household detergents to industrial cleaning and chemical processing.
For B2B buyers, the choice of SLS grade is usually based on purity, physical form, dissolution behavior, application, packaging, and required production performance.

Types of Sodium Lauryl Sulfate
| Feature | SLS Needle Form | SLS Powder Form |
| Dissolution Speed | Slightly slower — dissolves steadily but completely | Very fast — dissolves quickly due to large surface area |
| Dust Level | Very low — dust-free, safer for workers | High — creates dust during handling, may cause sneezing or irritation |
| Flowability | Excellent — flows freely, easy to pour and store | Poor — may clump or cake in humid conditions |
| Best For | • Liquid detergents, shampoos, body washes • Facilities wanting cleaner work environments • Automated dosing systems | • Dry blending and granulated products • Applications needing fast dissolution • Processes with good dust control systems |
SLS Needle Color Options
SLS needle products may be supplied in different colors or shades, depending on the production batch and agreed product specifications. Some needle grades can also be mixed with white needles for use in the same application.
For standard applications, the color of the SLS needle does not determine a different application. Buyers should focus on the agreed purity, active content, physical form, and specification when selecting a grade.
If appearance is important for the final formulation, customers can confirm the required color specification with HOO CHEMTEC before placing an order.
Advantages of Sodium Lauryl Sulfate/SLS
Superior Cleaning Power: SLS is a powerful anionic surfactant with excellent detergency, effectively removing oil, grease, and dirt from surfaces.
Rich and Stable Foam: It creates abundant, stable foam that consumers associate with effective cleaning — ideal for shampoos, toothpaste, and detergents.
Excellent Emulsifying Properties: It helps blend oil and water-based ingredients, keeping formulations stable and consistent.
Fast Biodegradability: SLS breaks down quickly in the environment, making it an eco-friendly choice for modern formulations.
Resistant to Hard Water: Maintains cleaning effectiveness even in hard water conditions, unlike some other surfactants.
Multiple Grades Available: We supply both powder and needle forms with active content from 92% to 95%, meeting various application requirements.
What is Sodium Lauryl Sulfate Used for?
Personal Care Products: Widely used in shampoos, body washes, facial cleansers, and toothpaste as a powerful foaming and cleaning agent.
Household Cleaners: A key ingredient in dishwashing liquids, laundry detergents, and all-purpose cleaners for removing grease and dirt.
Industrial Applications: Used in industrial cleaners, textile processing, and car wash products as an emulsifier and wetting agent.
Pharmaceutical & Laboratory: Functions as an emulsifier in creams and is essential for SDS-PAGE protein electrophoresis in research labs.
Agricultural Formulations: Serves as a wetting agent and dispersant in pesticide products to improve coverage on plant surfaces.
FAQ of Sodium Lauryl Sulfate/SLS
Sodium Lauryl Sulfate (SLS), also known as Sodium Dodecyl Sulfate, is an anionic surfactant widely used for its detergency, foaming, wetting, emulsifying, and dispersing properties.
Yes. Regulatory agencies and scientific reviews confirm that SLS is safe for use in consumer products at the levels typically found in shampoos, toothpastes, and body washes. It has been used safely for decades.
Typical usage levels: shampoos 10-20%, toothpastes 1-2%, liquid detergents 5-15% . Adjust based on your specific formulation and desired foam.
Yes. SLS is hygroscopic. Our packaging includes moisture-proof liners to protect product quality during sea transport, especially for powder form.

SLS powder and SLS needle have the same basic chemical identity but different physical forms. Powder is generally preferred where fast dissolution and dry blending are important, while needle products can provide better flowability and lower dust during handling.
HOO CHEMTEC supplies 92%, 93%, 94%, 95%, and 99% SLS. The 92% and 94% grades are available in needle form, while 93%, 95%, and 99% grades are available as powder.
HOO CHEMTEC supplies 92%, 93%, 94%, 95%, and 99% SLS. The 92% and 94% grades are available in needle form, while 93%, 95%, and 99% grades are available as powder.
The 99% grade is a high-purity SLS raw material positioned for applications requiring higher purity, including cosmetic-grade formulations. Because of its higher purity, it is more expensive than standard industrial grades. Buyers should confirm the required specification for their specific formulation.
20kg/multi-ply bags or 25kg/drum
The bulk material should be stored in a well-closed container away from strong oxidizing agents in a cool and dry place.
