Abstract
The disclosure relates to hard surface cleaning compositions, methods of making the hard surface cleaning compositions, and methods of using the hard surface cleaning compositions. In particular, the hard surface cleaning compositions have reduced surface tension for cleaning surfaces with low surface free energy. Preferably, the hard surface cleaning compositions have low contact angles on a variety of surfaces.
Claims20
A hard surface cleaning composition comprising:
- from about 1 wt. % to less than 10 wt. % of an anionic surfactant, wherein the anionic surfactant is sulfated, sulfonated, and/or carboxylated;
- up to about 6 wt. % of an amphoteric surfactant, wherein the amphoteric surfactant comprises an amine oxide, a betaine, a sultaine, or a mixture thereof;
- from about 0.5 wt. % to about 2 wt. % of a nonionic surfactant, wherein the nonionic surfactant is a C8-C18 linear or branched, alkoxylated surfactant;
- from about 0.01 wt. % to about 10 wt. % of a water conditioning agent comprising a polycarboxylic acid polymer;
- an alkaline pH modifier comprising an alkali metal carbonate, an alkali metal hydroxide, an alkanolamine, a metal silicate, a metal borate, or a mixture thereof;
- and
- water;
- wherein the composition has a pH of between about 8 and about 11.5;
- and
- wherein the hard surface cleaning composition has a viscosity of 100 cps or less.
