or a combination thereof.

3. The surfactant system of claim 1 , wherein the surfactant system comprises the alcohol alkoxylate according to formula (A) or the alcohol alkoxylate according to formula (A2), and the surfactant according to formula (D).

4. The surfactant system of claim 3 , wherein the weight ratio of the surfactant system comprises 5 to 80 parts by weight of the alcohol alkoxylate according to formula (A) or 5 to 80 parts by weight of the alcohol alkoxylate according to formula (A2), and up to 80 parts by weight of the surfactant according to formula (D).

5. The surfactant system of claim 4 , wherein the surfactant system comprises 10 to 20 parts by weight of the alcohol alkoxylate according to formula (A) or 10 to 20 parts by weight of the alcohol alkoxylate according to formula (A2), and 20 to 80 parts by weight of the surfactant according to formula (D).

6. The surfactant system of claim 4 , wherein the weight ratio of the surfactant system comprises from about 75 parts by weight of the alcohol alkoxylate according to formula (A) or about 75 parts by weight of the alcohol alkoxylate according to formula (A2), and about 25 parts by weight of the surfactant according to formula (D).
