Claims
- 1. A composition for wetting hydrophobic capillary materials, which composition consists essentially of:
- (a) a water-soluble nonionic surfactant selected from the group consisting of
- (a.sub.1) polyadducts of 4 to 30 mols of alkylene oxide with higher monoalcohols, fatty acids, fatty amines or fatty amides of 8 to 22 carbon atoms and
- (a.sub.2) reaction products of fatty acids of 8 to 22 carbon atoms and primary or secondary amines having at least one hydroxy(lower alkyl) or (lower alkoxy)(lower alkyl) group,
- (b) tributyl citrate,
- (c) a water-soluble anionic surfactant and
- (d) water.
- 2. A composition according to claim 1, wherein the anionic surfactant is a compound of the formula ##STR3## wherein R.sub.1 is alkyl or alkenyl, each of 8 to 22 carbon atoms, X.sub.1 is carboxyalkyl containing 1 to 3 carbon atoms in the alkyl moiety, and m is 2 to 30.
- 3. A composition according to claim 1, wherein the anionic surfactant is a compound of the formula ##STR4## wherein R is alkyl or alkenyl, each of 8 to 22 carbon atoms, alkylphenyl containing 4 to 16 carbon atoms in the alkyl moiety, or o-pbenylpbenyl, X is the acid radical of phosphoric acid or sulfuric acid or the radical of an organic acid and m is 2 to 30.
- 4. A process for wetting hydrophobic capillary material, which comprises treating said material with a composition as defined in claim 1.
- 5. A composition according to claim 1, wherein the water-soluble anionic surfactant is an alkarylsulfonate with linear or branched alkyl chain containing not less than 6 carbon atoms.
- 6. A composition according to claim 5, wherein the water-soluble anionic surfactant is dodecylbenzosulfonate.
- 7. A composition according to claim 5, wherein the water-soluble anionic surfactant is 3,7-diisobutylnaphthalenesulfonate.
- 8. A composition according to claim 1, which contains the water-soluble surfactants (a) and (c) and component(b) in a weight ratio of 20:1 to 1:1.
