Lanspec OF65
Product Category: Anionics
Alky Ether Sulfate Ammonium Salt
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:
