Which "SAFE" chemical is better?

Just going by what the experts tell me, doug. I'm not a scientist.

The reason olefin floats on water is that it has a specific gravity of less than 1.

The real issue here is that olefin absorbs NO MOISTURE.

In real terms that means that water rolls right down the fiber.

Maybe, doug. Maybe not. Do you have enough definite knowledge to say one way or the other either, or are you just resting on authoritative sources that you trust, just like most of us do? I don't see any need to prove my point; I just asked for your points as to why you disagreed. If I was misinformed or semi-misinformed by being swayed by nerdy terminology, then shame on me, I guess. It doesn't really affect how I do my job. The point was that I don't have enough knowledge of physical chemistry to report with any certainty exactly how water behaves on two hypothetical separate pieces of carpet whose only real difference is their respective specific gravities. In other words, I don't have specific knowledge of an experiement where water's propensity to travel past the piles of carpets of differing specific gravities was recorded, so I can't personally comment with absolute certainty. Are you asking me to look this stuff up in the appropriate journals and report back to you? I was just trying to be honest, because your request for me to explain "why" these things work the way they do would eventually lead down this path, right?

I just cut to the chase: none of us are scientists; we base our opinions on authorities that we trust (for whatever reason); then we compare knowledge to hopefully root out the truth, in time. If I'm wrong, I'd love to be enlightened, which I've already asked. You can either pony up with your definitive knwledge and its source, or you can just continue being vaguely contrary.

Have I sort of answered your question, or are you still waiting for . . . something?

I can appreciate that, doug.
