Popis
BS 6829-5.1:1990
This standard BS 6829-5.1:1990 Analysis of surface active agents (raw materials). Ethoxylated alcohol and alkylphenol sulphates is classified in these ICS categories:
- 71.100.40 Surface active agents
This International Standard specifies a method for the determination of the total active matter present in ordinary commercial neutralized products of sulfation of ethoxylated alcohols or alkylphenols [alkyl oxyethylene sulfates (ethoxylated alcohol sulfates) or alkylphenol oxyethylene sulfates (ethoxylated alkylphenol sulfates)].
The total active matter comprises the organic material soluble in ethanol (alkylether sulfates, alkylphenylether sulfates, polyglycol sulfates and non-ionic fractions).
Boiling under reflux with ethanol, filtration, evaporation of the filtrate and weighing of the residue. Correction by determining any sodium chloride present by titration with silver nitrate solution.
