Portuguese Natriumlaurylsulfat (SDS / K12)
Sodium Lauryl Sulfate – High-Performance Anionic Surfactant
Natriumlaurylsulfat (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 (Natriumlaurylsulfat) hat eine kürzere Kette und eine stärkere Schaumbildung, ist jedoch etwas reizender. AES (Natriumlaurethsulfat) enthält Ethoxygruppen, wodurch es milder ist und einen weicheren Schaum bildet. Oft werden beide Stoffe gemischt, um ein Gleichgewicht zwischen Wirksamkeit und Hautverträglichkeit herzustellen.
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.
