| BSI | 1989 | 14 |
This International Standard specifies a method for the estimation of the mean relative molecular mass of the anionic-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)] containing an average of not more than 20 oxyethylene groups per molecule.
It also sets out, in Annex A, a general scheme of analysis.
Estimation from the total active matter, the anionic-active matter, the polyglycol sulphate and unsulphated matter contents. Applicable to commercial neutralized products containing an average of not more than 20 oxyethylene groups per molecule.
