Patent number: 5565109Abstract: Free halogen sources (e.g., sodium hypochlorite and chlorine) added as slimicides in high organic component process streams such as pulp and paper processing are rendered more efficacious by the addition of selected N-hydrogen compounds (namely, 5,5-dimethylhydantoin, 5-ethyl-5-methylhydantoin, cyanuric acid, succinimide, urea, 4,4-dimethyl-2-oxazolidinone, and glycouril) to the process stream. The latter compounds may be added to the process stream before or after the slimicide is added or combined with the slimicide and added directly thereto. The direct use of halogenated hydantoins has also been found to provide improved efficacy relative to free halogen sources. In addition, absorbable organic halogen by-products are reduced.Type: GrantFiled: October 14, 1994Date of Patent: October 15, 1996Assignee: Lonza Inc.Inventor: Philip G. Sweeny

Patent number: 5547990Abstract: It has been found that certain combinations of substituted imidazoline-based amphoterics and quaternary ammonium compounds show markedly reduced irritation profile in addition to providing excellent cleaning detergency. Moreover, it has further been found that certain substituted imidazoline amphoteric surfactants in combination with didecyl dimethyl ammonium chloride (DIDAC) show unexpected synergistic irritation reduction compared to that observed when the quaternary is an ADBAC type. This allows the formulation of disinfectants and sanitizers with the favored antimicrobial agent while at the same time affording the optimum reduction in irritation potential.Type: GrantFiled: May 20, 1994Date of Patent: August 20, 1996Assignee: Lonza, Inc.Inventors: Larry Hall, Michael Y.

The preferred additive includes an essential amino acid residue selected from the group consisting of lysine, methionine, threonine, tryptophan, isoleucine and valine. Use of the di-and tripeptide additives of the invention gives increased nitrogen use by the animal, as compared with feeding of the amino acid constituents of the additives.Type: GrantFiled: September 16, 1994Date of Patent: June 11, 1996Assignees: Kansas State University Research Foundation, Lonza, Inc.Inventors: Jeffrey A.
