My boo-boo.
You prompted a good English lesson for me.
"Main Entry: hy·gro·scop·ic
Pronunciation: "hI-gr&-'skäp-ik
Function: adjective: readily taking up and retaining moisture
<glycerol is hygroscopic>
Source: Merriam-Webster Medical Dictionary, © 2002 Merriam-Webster, Inc. "
==============================
"As far as I am aware and can find in dictionaries, there is no word
"hydroscopic." "Hygroscopic", on the other hand, is a respectable word,
meaning the tendency of some materials to absorb moisture from humid air.
My dictionary offers the following definitions:
hy.gro.scop.ic ..........
1 : readily taking up and retaining moisture
2 : taken up and retained under some conditions of humidity and temperature
"hydroscopic": <=== Dictionary has no entry for hydroscopic"

=========================================================
"hy·dro·scope ( P ) Pronunciation Key (hdr-skp) n.
An optical device used for viewing objects far below the surface of water. "
==============================================
"hydroscopic.......commonly, erroneously used in place of hygroscopic"
Interestingly, there seems (from scanning some articles)
to be no distinction in "hygroscopic" between
absorbent (integrating)
["To take in; assimilate"]
["To take up by cohesive, chemical, or
any molecular action"]
&
adsorbent (holding)
["to accumulate on a surface"]
["one material attracting and holding molecules of another substance to the surface of its molecules"]
So 'absorb' can incorporate (absorb
![Big Grin :D :D](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
) 'adsorb'.
(btw - The respective actions of these words is absor
ption & adsor
ption.)
Thus doth my lesson end.
Thanks
