The role of solvent in dishwashing liquids
I wonder what would be the specific role of solvents in some premium dishwashing liquids like ethanol, butyl glycol or others. Is it mainly to dissolve grease or there is another purpose behind ?
For example here is a formula of a premium washing liquid from Kao Chemicals:

NaCl 1.6 (approx.) 0.5 (pH ≈ 7) q.s.
Citric acid (50%)
Preservative q.s
Colorant q.s
Deionised Water q.s up to 100%

1) Cloud point
2) Viscosity
3) Foam
Although 1 and 2 can alternate depending on the region/weather.
you can check this post of mine where I had trouble getting past 15% LABSA in dishwash

Cloudiness usually means it ain't properly dissolved
I believe propylene glycol and ethanol may work as solvents, increasing solubility for a more concentrated product.
Propylene glycol usually decreases solubility.
