Filed:

Nov 22, 2000

Appl. No.:

09/721523

Inventors:

Michael Yao-Chi Chiang - Flemington NJ
Larry Kent Hall - Northampton PA

Assignee:

Lonza Inc. - Fair Lawn NJ

International Classification:

A61K 3114

US Classification:

514642, 514563, 514912

Abstract:

The present inventors have discovered that electrolytes, such as the tetrasodium salt of ethylenediaminetetraacetic acid (EDTA), reduce the ocular irritation and increase the disinfecting and sanitizing efficacy of compositions containing quaternary ammonium compounds and/or amines. As a result, concentrated solutions containing quaternary ammonium compounds and/or amines of the present invention have low, if any, ocular irritation. Furthermore, use dilutions of the concentrated solutions of the present invention include ingredients which are approved by the U. S. EPA for use on indirect food contact surfaces, unlike disinfecting and sanitizing compositions containing imidazoline compounds. Additionally, the use dilutions exhibit superior efficacy against gram negative and positive bacteria compared to similar compositions which do not contain the electrolyte and remain effective in hard water. The present invention is a concentrate, such as a sanitizing and disinfecting concentrate, comprising from about 0.

Appl. No.:

10/032204

Inventors:

Michael Chiang - Flemington NJ, US

Assignee:

Lonza Inc.

International Classification:

A61K007/50

US Classification:

510/130000, 510/138000, 510/156000, 510/382000, 510/387000, 510/504000

Abstract:

The present invention is directed to a sanitizing composition including (a) a sanitizing effective amount of an antimicrobial agent, (b) a water-soluble silicone, (c) a humectant selected from the group consisting of hydrogenated starch hydrolysates, glycerin, and mixtures thereof, and (d) water. This sanitizing composition is preferably substantially free of alcohol and more preferably contains less than about 0.5 or 1% by weight of alcohol, based upon 100% by weight of total composition. The hand sanitizer of the present invention is non-flammable, disinfects and/or sanitizes surfaces rapidly, and quickly dries after application. Another embodiment is a method of disinfecting and/or sanitizing a surface which comprises applying the aforementioned hand sanitizer composition to the surface. In particular, the hand sanitizer composition may be topically applied to hands, face and other surfaces of the body to disinfect and sanitize the same.

Assignee:

LONZA INC. - Allendale NJ

International Classification:

C09D 5/08

US Classification:

428418, 4273881, 4284258, 428461, 428460, 428462, 428458

Abstract:

Disclosed are quaternary ammonium salts containing non-halogen anions (e.g., quaternary ammonium carbonates, bicarbonates, and mixtures thereof) as anti-corrosive agents. The invention relates to a method for inhibiting the corrosion of metal surfaces by applying a composition containing one or more quaternary ammonium carbonate or bicarbonate. The disclosure is also directed to anti-corrosive coatings for metal substrates containing these compounds, to metal substrates having these anticorrosive coatings, and to aqueous cleaning solutions containing these compounds.

Filed:

Sep 3, 1998

Appl. No.:

9/146880

Inventors:

Michael Yao-Chi Chiang - Flemington NJ
Daniel Wayne Lemke - Jersey Shore PA
Joseph William Scheblein - Flemington NJ

Assignee:

Lonza Inc. - Fair Lawn NJ

International Classification:

C11D 118
C11D 175

US Classification:

510245

Abstract:

The subject invention relates to a novel class of compounds, known as alkali metal salts of hydroxyalkyl sulfonates of aminoalkyl alkanol amines and/or aminoalkyl alkanol ethers, the methods of making such compounds, the alkali-stable solutions containing such compounds, and the use of said solutions as strong detergent compositions. Those alkali-stable solutions are temperature-stable, exhibit superior wetting characteristics, and can be made into low or high foam formulations useful for hard surface cleaning, oven and grill cleaning, metal cleaning, bottle washing, steam cleaning and wax stripping formulations.
