Flow properties of a newtonian or non-newtonian test portion are determined by means of a specified rotational viscometer, which will allow, for the newtonian products, the simultaneous measurements of the shear rate at which the determination is carried out, but for the non-newtonian products, possible measurement of various apparent rates of shear used for the determination.

A test portion is boiled under reflux with ethanol in the presence of sodium sulphate. The solution is filtrated, the filtrate evaporated, and the residue weighed. Any sodium chloride present is determined by dissolution of the residue in aqueous acetone and titration with a standard volumetric silver nitrate solution. The mass of the residue is corrected for the sodium chloride content.

Methods for the determination of the following characteristics of the test pieces after washing are specified: intrinsic greying, intrinsic yellowing, increase in organic deposit content, increase in incineration residue, overall decrease in breaking strength, decrease in breaking strength resulting from chemical degradation of cellulose due to laundering and from mechanical factors in laundering. Annexes contain the determination of increase (or decrease) in degree of whiteness and of chemical wear and further a grey scale and the measurement of reflection.

The sample is hydrolyzed by nascent hydroiodic acid. The iodine liberated is titrated with a standard volumetric sodium thiosulfate solution. The method is applicable to the analysis of polyethoxylated derivatives of primary saturated fatty alcohols, oleyl alcohol, satureted fatty acids, straight and branched chain alkylphenols. It is not applicable in the present of compounds containing sulfur or nitrogen, compounds containing oxypropylene group, aldehydes or acetals, sterols and derivatives.

A test portion is dissolved in ethanol and the solution is acidified. The alkane monosulfonic acids are separated from the alkane disulfonates and sulfate ions by extraction with light petroleum. The light petroleum phase is evaporated and the residue is solved in ethanol. Traces of alkali are removed by means of a cation-exchange column. The eluate is neutralized with carbonate-free sodium hydroxide solution. The sodium alkane monosulfonates so formed are dried and weighed. The mean relative molecular mass of the alkanemonosulfonates and the alkanemonosulfonate content are calculated.
