pretty sure it is just elmers glue [SEP] i am pretty sure this is just elmers glue in a bottle it does not even have a label on the bottle no ingredients no instructions just goopy tacky white stuff in a frosted white bottle that being said it is somewhat effective you just have to experiment to figure out when the best time to remove is sometimes it work flawlessly and other times it pulled my nail polish up with it it is not worth the effort unless your doing something more artistic messy with your nail polish like using a sponge to apply it
