Solid rinse aid composition and method of making same

摘要

The invention includes a solid rinse aid that is particularly designed for pressed or extrusion solid formation and which is effective for spotless surfaces after rinsing, especially rinsing metals without corrosion. According to the invention, a solid acid is combined with a short-chain alkylbenzene and alkyl naphthalene sulfonate. The short-chain alkylbenzene and alkyl naphthalene sulfonate act as a solidification agent as well as a hydrotrope, and total dissolved solid (TDS) active and are combined with at least one nonionic low foaming surfactant.

主权项

1. A solid rinse aid composition comprising:
from about 15 wt. % to about 40 wt. % of a solid acid, wherein the solid acid includes one or more of the following: citric acid, phosphoric acid, monosodium citrate, disodium citrate, potassium citrate, monosodium tartrate, disodium tartrate, potassium tartrate, and aspartic acid; from about 65 wt. % to about 85 wt. % of one or more short chain alkyl benzene and/or alkyl naphthalene sulfonates, wherein said one or more short chain alkyl benzene and/or alkyl naphthalene sulfonates includes one or more of the following: sodium xylene sulfonate, sodium toluene sulfonate, sodium cumene sulfonate, potassium toluene sulfonate, ammonium xylene sulfonate, calcium xylene sulfonate, sodium alkyl naphthalene sulfonate, and sodium butylnaphthalene sulfonate; and one or more nonionic surfactants; wherein said solid rinse aid composition provides a use solution with a pH of less than 2, wherein said solid rinse aid promotes drying and prevents the formation of spots on a metal surface.
