(a) 10-30% octyl or dodecyl pyrrolidone,
(b) 50-90% of an ethoxylated alcohol,
(c) 0.5-5% of a compatabilizer for (a) and (b), and
(d) 0-10% water.
2. A stable wetting concentrate according to claim 1 wherein (b) is ethoxylated nonyl alcohol.
3. The wetting concentrate of claim 1 wherein (b) contains 2 or 3 EO units.
4. The wetting concentrate of claim 1 wherein the weight ratio of (a):(b) is about 80:20.
5. The wetting concentrate of claim 1 wherein (c) is sodium lauryl sulfate or sodium laureth sulfate.
6. The wetting concentrate of claim 1 wherein (c) is an anionic emulsifier.
7. A stable wetting concentrate of claim 1 wherein
(a) is 19%,
(b) is 76%,
(c) is 1.5, and
(d) is 3.5%.
