No, it's not. The study that I linked to
mentioned a previous study on a spermicide, N-9. The linked study in question discusses hyperosmolar water-based lubricants ONLY. The word spermicide doesn't even
appear in the article.

Where did your study point out normal soughing of the skin?
|
"Recently, Phillips et al. demonstrated that rectal application of N-9 resulted in sloughing of
surface epithelia [this is the rectal lining, not skin].
Hyperosmolar fluids have been shown to induce similar changes in the distal colon."
Many water-based lubes are hyperosmolar, per the study--No spermicide required to cause epithelial sloughing.

Your question makes no sense. ... Their are small tears during anal...

"Small tears" does not equal "stripping off epithelium." My question, which was not addressed by the study, was whether or not stripping off the epithelium is significant by itself (IOW: Does it enable friction to cause worse damage to the remaining lower layers more easily? Is it reason enough to avoid lubes that may strip the epithelial layer?).
I'm thinking that silicone lubes might be better for anal sex than hyperosmolar water-based ones, but I could be mistaken... Which is why I asked
Brandye this question in the first place.
Anyway, forget that I even asked about this. I'll PM Brandye and hopefully get better results, not insults.
