Abstract: A broad spectrum antimicrobial composition comprising a mixture of an iodopropynyl compound in combination with a benzimidazole and a metal borate is disclosed. The composition can be used to protect industrial systems against microbial growth and, more particularly, to protect substrates such as paints, coatings, stucco, concrete, stone, cementaceous surfaces, wood, wood-plastic composites, caulking, sealants, textiles, leather, wood, preservatives, metal working fluids, drilling muds, clay slurries, glazes, optical brighteners, carpet backing, and pigments against microbial growth. The composition can be used as a preservative for aqueous products.

Abstract: The present invention provides antimicrobial compositions comprising an antimicrobial agent and a thermally stabilizing effective amount of an amide based stabilizing agent. The present invention also provides polymeric-cellulosic fiber formulations comprising a polymeric-cellulosic fiber composition and an antimicrobially effective amount of the antimicrobial composition. The present invention further provides a method of thermally stabilizing an antimicrobial agent and an improved method for making a polymeric-cellulosic fiber formulation with antimicrobial activity.

Abstract: A non polluting additive or spotting fluid which lubricates, releases and/or prevents differentially stuck drill strings and casings in the wellbore of a subterranean well is presented. This additive composition comprises a glycol or glycol ether derived from a long chain epoxide of greater than 3 carbon atoms (preferably greater than 10 carbon atoms); and preferably comprises the reaction product between 2-ethylhexanol and the epoxide of 1-hexadecene. The present invention enhances the lubricity of a drilling fluid to prevent drill string sticking and when utilized as a spotting agent reduces the time required to release a stuck pipe. This invention also helps reduce or prevent foaming. By eliminating the need for traditional oil-based components, the present invention is nontoxic to marine life, biodegradable, environmentally acceptable, easy to prepare, and capable of being disposed of at the drill site without costly disposal procedures.

Abstract: A method of promoting weight gain in an animal by feeding the animal calcined attapulgite which reduces adverse effects of a mycotoxin present in an animal food formulation. The calcined attapulgite is obtained by heating an attapulgite clay at or above 300.degree. F. The calcined attapulgite can be fed to an animal in any form either before, after, or during intake of food by the animal. Furthermore, a mixture of calcined attapulgite and bentonite may be used, instead of calcined attapulgite itself. Also provided is an animal feed composition for promoting weight gain including calcined attapulgite. Such a composition reduces adverse effects of a mycotoxin-contaminated animal feed. The composition may further contain a bentonite clay.
