Filed:

May 12, 1997

Appl. No.:

8/854405

Inventors:

Thomas R. Oakes - Marine MN
Timothy A. Gutzmann - Eagan MN
Cynthia Lee Ross - Roseville MN
Bruce E. Schmidt - St. Paul MN

Assignee:

Ecolab Inc. - St. Paul MN

International Classification:

C11D 162
C11D 706

US Classification:

510179

Abstract:

The invention is a method of removing soils containing oils and fats from food processing surfaces. The method includes the steps of formulating a wash composition from a two-part concentrate. The concentrate first part includes a source of alkalinity and water. The concentrate second part includes a quaternary ammonium compound. After formulation, the wash composition has a major portion of water, from about 100 ppm to 20,000 ppm of quaternary ammonium compound, and an alkali source present in a concentration to provide a pH of from about 10 to 14. After formulation, the wash composition may be used by applying it to the food processing surface. Optionally, the wash composition may also include a chelating agent and a second nonionic or anionic detersive agent.

International Classification:

B29C 3360

US Classification:

106244

Abstract:

The invention is methods and compositions for removing bonding agents from the hard surfaces of machinery and, in its most preferred mode packaging equipment. The release composition comprises lecithin and a hydrophobic carrier. The method comprises the steps of applying a release composition to the surfaces of the packaging equipment. The packaging equipment is then used. Any bonding agent deposited on the treated areas of the packaging equipment may then be removed. The invention is applicable to any number of package and container manufacture environments including package assembly, package sealing, product sealing, and labeling.

International Classification:

US Classification:

106 2

Abstract:

The invention relates to a coating composition film or barrier layer containing an inorganic salt composition having a phosphate and a carbonate source and a surfactant composition. The aqueous coating can be applied to surfaces in food preparation units. The compositions of the invention can be used in methods for coating hard surfaces of food preparation units by applying the aqueous material through a spray or other aerosol apparatus to form a uniform coating. Upon drying, the water from the coating can evaporate leaving an organic/inorganic film which can support baked-on food soil and promote easy removal.
