Frequently Asked Questions
What is Magnesium Alkyl Ethoxy Sulphate 70% used for?
It is an anionic surfactant used as a primary foaming and cleansing agent in shampoos and body washes, and as a detergency component in liquid household and industrial cleaners. It is supplied as an approximately 70% active paste.
What is the other name for this surfactant?
Magnesium alkyl ethoxy sulphate is also called magnesium laureth sulfate or magnesium alkyl ether sulfate (CAS 62755-21-9). The "70" refers to its roughly 70% active concentration.
Is this the same as magnesium sulphate?
No. Magnesium alkyl ethoxy sulphate (CAS 62755-21-9) is an anionic alkyl-ether-sulfate surfactant, whereas magnesium sulphate (Epsom salt, CAS 7487-88-9) is a simple inorganic salt. They are chemically distinct materials with different uses.
What is the active content and form of the 70% grade?
It is supplied as a roughly 70% active surfactant paste. Confirm exact active matter, pH, and lot values against the Certificate of Analysis for each shipment.
How is bulk magnesium laureth sulfate 70% supplied and priced?
It is supplied in bulk for surfactant and cleaner formulation. Pricing depends on volume and packaging (drum, tote, or larger); request a bulk quote with your target quantity for current pricing, CoA, and SDS.
What is the REACH and TSCA regulatory status of Magnesium Alkyl Ether Sulfate (Magnesium Laureth Sulfate)?
Magnesium Alkyl Ether Sulfate (Magnesium Laureth Sulfate) (CAS 111937-03-2) is subject to U.S. TSCA Inventory requirements; supplying it into the EU requires valid REACH registration ((EC) No 1907/2006). RawSource cannot verify a third-party supplier's registrations — buyers should require documented TSCA and REACH compliance for their jurisdiction and volume (EC 601-141-6).
