Abstract
The invention relates to a wetting composition comprising (a) from 20 to less than 50 wt % of one or more C10 to C14 alcohol, (b) 25 to 70 wt % of a surfactant selected from a non-ionic, cationic, anionic and amphoteric surfactant, and (c) from 5 to 50 wt % of a polar component comprising at least one selected from (i) water, and (ii) up to 25 wt % of a water-miscible C1-C3 organic solvent, to methods for using the wetting composition, and products and aqueous compositions containing the wetting composition
Claims15
A method of lowering the surface tension of an aqueous liquid, said method comprising the step of adding a wetting agent to the aqueous liquid, wherein the wetting agent is in the form of a composition consisting of:
- (a) 20 to less than 50 wt % of one or more C10-C14 alcohol;
- (b) 25 to 70 wt % of one or more surfactant selected from a non-ionic, cationic, anionic and amphoteric surfactant;
- and
- (c) 5 to 50 wt % of a polar component comprising at least one selected from (i) water, provided that the water is at most 10 wt % of the wetting agent, and (ii) a water-miscible C1-C3 organic solvent, provided that the water-miscible C1-C3 organic solvent is at most 25 wt % of the wetting agent;
- and
- (d) 0 to 10 wt % other additives;
- wherein the reduction in surface tension increases with the amount of wetting agent that is added.
