ABSTRACT:
Cyclodextrin complexes are prepared utilizing processes in which the cyclodextrin/active complex is prepared under concentrated reaction conditions in which there is no more than about 40% solvent, e.g., water, with mechanical working, to provide a complex ultimate particle size of less than about 12 microns and the resulting complex reaction mixture is incorporated, preferably without further operation, into at least one fabric conditioning material, preferably cationic fabric conditioning active, preferably in liquid (molten) form, preferably at a temperature between about 60 and about 95.degree. C., and mechanically worked to reduce complex aggregate particle size below about 200 microns. The resulting complex/fabric conditioning material mixture is used to prepare, e.g., dryer-added fabric softener article, e.g., sheet. The mixture of complex and fabric softener material preferably contains a small amount of an anionic surfactant to help avoid deposition of, e.g., unreacted cyclodextrin onto the equipment used to prepare the fabric conditioning composition and/or article (sheet).
