Portuguese Sodium Lauryl Sulfate (SDS / K12)
Sodium Lauryl Sulfate – High-Performance Anionic Surfactant
Sodium Lauryl Sulfate (SDS / K12) is a typical anionic surfactant with the chemical formula C₁₂H₂₅SO₄Na. It offers excellent emulsifying, foaming, penetrating, detergency, and dispersing properties. It produces rich, fine foam, has good compatibility, and exhibits excellent hard water resistance. It is widely used in daily chemical and personal care, detergent industry, textile industry, building materials and coatings, and oilfield applications.
- Excellent emulsifying and detergency performance
- Rich and fine foaming ability
- Good hard water resistance
- Good compatibility with anionic and non-ionic surfactants
- Multiple forms available: liquid, needle, powder

FAQ
K12 (Sodium Lauryl Sulfate) has a shorter chain and stronger foaming power with slightly higher irritancy. AES (Sodium Laureth Sulfate) contains ethoxy groups, making it milder with softer foam. They are often blended to balance performance and mildness.
At typical usage levels, K12 is safe. However, compared to milder surfactants (such as AES or amino acid surfactants), K12 has slightly higher irritancy. In personal care formulations, irritation can be reduced by blending with other mild surfactants.
Yes. K12 has good biodegradability and meets modern environmental requirements.
Both have similar active matter content (≥92%). The main difference is physical form. Needle crystals dissolve at a moderate rate, while powder dissolves faster. The choice depends on your production process and dissolution equipment.
