Patent number: 6384006Abstract: A system for forming and releasing an aqueous peracid solution is disclosed. The system includes a container and a peracid forming composition provided within the container. The container is permeable to the passage of water and aqueous peracid solution. The peracid forming composition includes a peracid precursor and a peroxygen source. Preferably, the peracid forming composition includes a chemical heater capable of releasing heat upon hydration. When placed in water, water enters the container and interacts with the peracid forming composition provided within the container. The water combines with the peracid precursor and peroxygen source to provide an aqueous peracid composition. The presence of a chemical heater within the container provides for the generation of heat within the container which enhances the rate of peracid formation. The peracid solution leaves the container and forms an effective sanitizing amount of sanitizer.Type: GrantFiled: September 25, 2001Date of Patent: May 7, 2002Assignee: Ecolab Inc.Inventors: G.

Patent number: 6017864Abstract: We have found that long standing problems relating to the stability of organic materials in alkaline detergents, including the reversion or hydrolysis of condensed phosphate sequestrants in alkaline solid detergent compositions can be alleviated by the use of an organic composition having vicinal hydroxyls. Such a solid block detergent can be manufactured by a process in which a source of alkalinity, a functional material including a condensed phosphate sequestering agent, an organic compound having two vicinal hydroxyl groups, are combined in a pourable composition or liquid. Such a liquid can be introduced into a plastic capsule and solidified. During manufacture and solidification, we have found that the vicinal hydroxyl compound prevents substantial hydrolysis or reversion of the condensed phosphate maintaining effective hardness ion sequestration during the use of the detergent. The stabilizer can also stabilizes color, chlorine content and dispensing properties.Type: GrantFiled: December 30, 1997Date of Patent: January 25, 2000Assignee: Ecolab Inc.Inventors: Kent R.
