Hello - my questions have to do with cleaning solution formulas.
1) Are surfactants known to provide better spreading?
2) Are surfactants known to provide adherence?
3) Is adherence and spreading directly correlated? I think not, but I am not sure and I haven't yet found a citation or an article, textbook, or anything to support that adhering and spreading are not correlated. Could someone direct me to a citation?
4) Spreading may result from a reduction in the surface tension of a composition, but at the same time, that composition may be more likely to run off and not adhere to the surface than a composition with higher surface tension. (Is this true?) If yes, could you possibly lead me to a literature citation to support this?
