SLS (Sodium Lauryl Sulfate) – Anionic Surfactant Supplier from China
SLS (Sodium Lauryl Sulfate), also known as Sodium Dodecyl Sulfate (SDS), is a widely used anionic surfactant with excellent cleansing, emulsifying, wetting, and foaming properties. It is commonly used in detergents, personal care products, cosmetics, industrial cleaners, and various chemical formulations.
SLS is available in different physical forms, including powder, needle, and granular grades, according to different manufacturing and application requirements. It is one of the most commonly used sulfate surfactants in the global detergent and personal care industries.
We supply SLS (Sodium Lauryl Sulfate / K12) from China for international customers, importers, distributors, and manufacturers. Product specifications, COA, SDS, TDS, and export documents can be provided according to customer requirements.
SLS Product Information
| Product Name | Sodium Lauryl Sulfate |
| Abbreviation | SLS / SDS / K12 |
| CAS Number | 151-21-3 |
| Chemical Type | Anionic Surfactant |
| Appearance | White powder, needle or granular |
| Active Matter | Usually ≥92% |
| Solubility | Soluble in water |
SLS is produced through the sulfation and neutralization of lauryl alcohol. Its molecular structure contains a hydrophobic alkyl chain and a hydrophilic sulfate group, allowing it to reduce surface tension and provide strong cleansing and foaming performance.
SLS as an Anionic Surfactant
SLS belongs to the anionic surfactant family and is widely recognized for its strong detergency and foam generation.
The main functions of SLS include:
- Cleansing agent
- Foaming agent
- Emulsifier
- Wetting agent
- Surface tension reducer
Because of its excellent cleaning ability and cost effectiveness, SLS has become an important raw material in detergent and personal care formulations.
SLS for Detergents and Cleaning Products
One of the major applications of SLS is in detergent and cleaning products.
SLS can effectively remove oil, grease, and dirt by lowering surface tension and improving the interaction between water and oily substances.
Applications include:
- Laundry detergents
- Household cleaners
- Dishwashing products
- Industrial cleaning agents
- Powder detergent formulations
Its strong cleaning ability and good foaming performance make SLS suitable for formulations where high detergency is required.
SLS for Personal Care and Cosmetics
SLS is widely used in personal care and cosmetic formulations as a cleansing and foaming ingredient.
Common applications include:
- Shampoo
- Facial cleanser
- Body wash
- Hand wash
- Toothpaste
- Shaving products
In personal care formulations, SLS helps remove oils and impurities while producing rich foam. However, because SLS provides stronger cleansing performance compared with some milder surfactants, formulators often combine it with other surfactants to achieve the desired balance of cleansing power and mildness.
SLS Powder, Needle and Granular Grades
SLS is commercially available in different physical forms.
SLS Powder
SLS Powder is widely used because it is easy to mix, transport, and process in dry formulations. It is commonly used in detergent powders and chemical formulations.
SLS Needle
SLS Needle has a needle-like particle structure and is commonly selected for specific processing requirements where particle shape and handling properties are important.
SLS Granular
SLS Granular provides good flowability and is suitable for applications requiring easier handling and dosing.
The appropriate physical form depends on the customer’s production process, formulation method, and equipment requirements.
SLS vs SLES
SLS and SLES are both sulfate-based anionic surfactants, but their chemical structures are different.
SLS (Sodium Lauryl Sulfate):
- Formula: C₁₂H₂₅SO₄Na
- Strong cleansing and foaming ability
- Commonly supplied as powder, needle, or granules
- Widely used in detergents and personal care
SLES (Sodium Laureth Sulfate):
- Ethoxylated sulfate surfactant
- Contains ethylene oxide units
- Usually supplied as a paste, such as SLES 70%
- Commonly used in shampoos, shower gels, and liquid detergents
Both products are important surfactants, but the suitable choice depends on the formulation requirements.
SLS Applications in Industrial Formulations
Besides detergents and personal care products, SLS can also be used in various industrial applications where strong wetting, emulsification, or foaming properties are required.
Potential applications include:
- Industrial cleaners
- Textile processing
- Emulsion systems
- Chemical formulations
- Laboratory and specialty applications
The required specification depends on the final application and technical requirements.
