Many products for personal cleansing are advertised as "flushable". However, simply because the commode will take them doesn't mean that the sewer system will break it down. The fibrous wipes do not break down. They find something to wrap the,selves around and wait to collect more stuff until the line is plugged. I have been called to many backups in our city system and found just such things were the problem.
Nothing further needs sayin', eh?
