Use of a starch base copolymer in conjunction with a maleic polymer and a hydroxypolycarboxylic acid to control hardness under alkaline conditions |
摘要 |
The present invention includes methods and compositions control hard water in an alkaline environment. According to the invention, a unique combination of polymers has been developed which helps to completely control and eliminate hard water. The composition includes a maleic polymer, a hydroxypolycarboxylic acid, and a starch based polymer in a unique synergistic combination that can be used alone, or in combination with standard alkaline detergents in any cleaning regime (laundry, warewash, etc.) where hard water conditions exist. |

1. A hardness control composition for use in alkaline cleaning conditions comprising:
a starch based hybrid polymer, a maleic polymer and a hydroxycarboxylic acid salt; wherein said starch based hybrid polymer comprises 30 wt. % to 80 wt. % of a hybrid copolymer of starch, 5 wt. % to 60 wt. % of AMPS, and 0.1 wt. % to about 5 wt. % of an acrylic acid monomer. |
