Default Is tooth brushing water from hot tap safer than from cold tap?

The message
from Chris Bacon contains these words:

PEG-6 (?)


Polyethylene glycol. The 6 tells you how long the chain is.

PEG is used in a number of toothpastes as a dispersant; it binds water
and helps keep gum uniform throughout the toothpaste. It is also used in
liquid body armor [3] and tattoos to monitor diabetes[4]. Functional
groups of PEG give polyurethane elastomers their "rubberiness", for
applications such as foams (foam rubber) and fibers (spandex). Its
backbone structure is analogous to that of silicone, another elastomer.
