Abstract
A low foaming surfactant blend for use in highly alkaline conditions including at least one C3 to C10 alkyl polyglucoside, at least one amine oxide, at least one polycarboxylated alcohol alkoxylate, and at least one alcohol alkoxylate. The blend may combined with other optional ingredients including a source of alkalinity, water conditioning agents, a source of chlorine, silicates, solvents, high foam amine oxides, other surfactants, and so forth to form a cleaning concentrate. The concentrate may be diluted to use solutions with water.
Claims35
A low foaming surfactant blend for use in highly alkaline conditions, comprising:

- a) about 1 part by weight of at least one alkyl polyglucoside;
- b) about 0.02 to about 1.5 part by weight of at least one amine oxide;
- c) about 0.02 to about 3.0 parts by weight of said at least one polycarboxylated alcohol alkoxylate;
- and
- d) about 0.02 to about 1 part by weight of at least one alcohol alkoxylate.
