Lanspec OF65

Product Category: Anionics

Alky Ether Sulfate Ammonium Salt

Quick Links

Lanspec OF65 is an ammonium neutralised alkyl ether sulphate and finds application where high foaming, characteristics are required, particularly in the presence of highly levels of electrolyte and polyvalent metal ions. Lanspec OF65 has good stability in the presence of alkaline solutions at moderate temperatures, but will hydrolyse in acidic solutions. Lanspec OF65 finds applications in a range industries due to it’s key properties which include:
