...to get to the center of a Tootsie Pop?

Subtle is not my strong point but I can recognize...

Hot water or cold water? Soft water or hard water? Actual soap or syndet bar? Economy brand or name brand, or boutique brand?

Given my background in surfactants i could not adequately answer that question without those variables supplied.

sur·fac·tant
sərˈfaktənt/Submit
noun
plural noun: surfactants
a substance that tends to reduce the surface tension of a liquid in which it is dissolved.

I've been working on the chemistry, reaction and phase/physical, of surfactants for a LONG time. I have to know about 1000 people in the cleaning products business around the world from companies, both big and small, premium and economy.

Soap is a surfactant, but less effective, especially in hard water than detergents. Chemically they're different and almost nobody knows it. Well, let's be honest, nobody really cares either, except for geeks like me.

Word of the day is....surfactant

It is an interesting field and it's something everyone needs to keep clean, and the stuff in consumer products is nearly 100% biodegradable, so there's not a giant negative impact on water and air.

I suppose that's better than pesticides and herbicides.
