Data confidence 85 high

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

Effect of anionic polyelectrolyte sodium carboxymethylcellulose on surface tension of alkyl sulphate derivatives of sulphoacid solutions, sodium dodecyl sulphate and ammonium dodecyl sulphate, has been investigated. It has been established that the compositions of surfactants–sodium carboxymethylcellulose show an appreciable synergetic effect of surface tension decrease. The values of surface activity and kinetic adsorption constants of the associates of surfactants with NaCMC at the interface liquid-gas were determined.
