The composition of the present invention includes a surfactant blend of an ethoxylated sorbitan ester and at least one additional nonionic or anionic surfactant. The combination of the ethoxylated sorbitan ester and additional surfactants used in the invention surprisingly has a synergistic effect on the removal of oligomer deposits from polyester fibers and polyester processing equipment.Type: GrantFiled: May 24, 2005Date of Patent: April 24, 2007Assignee: Nicca USA, Inc.Inventor: Kazu Ikebata

Patent number: RE40495Abstract: An article for sanitizing a surface with a sanitizing solution while maintaining the concentration level of a sanitizer in the sanitizing solution at an effective concentration level. A substrate that absorbs and holds the sanitizing solution is treated with a sanitizer release polymer composition. The substrate may be a woven, nonwoven, or knit fabric, a foam or sponge, or the like. The sanitizer release polymer composition may include a cationic or nonionic surfactant or binder that is operable to maintain the concentration level of the sanitizer at the effective level during prolonged periods of use.Type: GrantFiled: March 9, 2005Date of Patent: September 9, 2008Assignee: Commun-I-Tec, Ltd.Inventor: Jeffrey S.
