Are K12, SDS and SLS the same product?
Yes. K12, SDS and SLS generally all refer to sodium dodecyl sulfate (sodium lauryl sulfate), CAS 151-21-3. They are common names for the same product, available in powder, needle and liquid forms that can be selected by active content and application.
What is the difference between powder and needle grades of SDS?
Powder and needle grades differ mainly in physical form and some specifications (active content, whiteness, inorganic salt content), but are chemically the same product. Powder is typically ≥94% active and needle ≥90%. The choice depends on your dosing process and dissolving needs; please confirm the exact grade with Bio-CORNIGS.
What information should I provide to get a K12/SDS quotation?
To receive an accurate quotation, please provide the required form (powder/needle/liquid) and active content, purchase quantity, application field (home & personal care, food, electrophoresis reagent, etc.), packaging requirement, destination port or delivery address, and whether COA, MSDS or other documents are required.
Can sodium dodecyl sulfate be used in food or biochemical applications?
Sodium dodecyl sulfate can be used as a food industry processing aid under GB2760 and is also widely used in biochemical analysis and electrophoresis. Purity and specification requirements differ by application, so please specify the intended use; the corresponding batch specification and MSDS will prevail.
