Abstract
Aqueous compositions, which are aqueous solutions or suspensions of effect materials containing anionic or cationic surface active agents and condensates of from one to four molar proportions of ethylene oxide with aliphatic alcohols having from seven to fifteen carbon atoms, have good wetting properties and are valuable for applying the effect materials to solid substrates. Suitable effect materials include dyestuffs, textile finishing agents, biocides and especially agrochemicals such as herbicides, fungicides and pesticides.
Claims10
Aqueous surface active agent compositions having improved wetting properties for use in applying dyestuffs to solid surfaces which contain,
- one or more cationic surface active agents selected from the group consisting of alkyltrimethylammonium halides, alkylbenzyldimethylammonium halides, alkylpyridinium halides, alkylquinolinium halides, alkylinidazolinium halides and alkylmorpholinium halides, or
- one or more anionic surface active agents selected from the group consisting of the sodium salts of alkyl sulphates, aromatic sulphonates, condensates of aldehydes and aromatic sulphonic acids, lignin sulphonates and of sulphated natural oils, and
- one or more condensates of from 2 to 3 molar proportions of ethylene oxide with an aliphatic alcohol containing from seven to fifteen carbon atoms,
- the ratio of cationic/anionic agent to ethylene oxide condensate in the range of 1:3 to 20:1, the total amount of cationic/anionic agent together with ethylene oxide condensate is from 0.01 to 5% of the aqueous composition and from 0.01 to 5.0% of dyestuff.
