It is thus complementary to method SLO 2/16 which determines the total free fatty acid due to hydrolysis. The method applies particularly to ammonia or amine neutralised sulphated oils which will not titrate by the simple method SLO 2/5. Such samples are often unstable and lose ammonia fairly rapidly on standing. The method determines the un-neutralised free fatty acid at the time of the test and should be repeated if the result is required again later.
