Solubilizing and Detackifying Stickies with ß- Cyclodextrin

ß-Cyclodextrin (ß-CD) solubilizes stickies from deinked pulp, commercial adhesive formulations, or magazine inserts, which demonstrates its potential as a washing aid. A new test to simulate coater scratches is described; it involves scraping the test paper sample across the surface of a thin layer chromatography plate and measuring the degree of scratching on the plate. Scratching was significantly reduced when the paper was pre-treated with ß-CD. A trial at a recycle paper mill confirmed that ß-CD reduces the tack of filtrate components.
