COPPER BIOCIDES ARE DANGEROUS ACCORDING TO ECHA COMMITTEE

 Cleanroom Technology: January 2015

Biocides containing copper flakes should be classified as hazardous for humans, the Committee for Risk Assessment of the European Chemicals Agency (ECHA) has decided.

In a recommendation on the classification and labelling of chemicals used and sold in the European Union (EU), the committee backed proposals from France that these biocides should be regarded as harmful under certain circumstances. Indeed, the committee decided that biocides based on copper (II) hydroxide are fatal if inhaled, cause serious eye damage and can be harmful if swallowed. Also dicopper chloride trihydroxide-based biocides are toxic if swallowed and harmful if inhaled, said the committee.

The committee added that biocides containing copper flakes (coated with aliphatic acid) and basic copper carbonate should be classified as harmful if swallowed; they can also cause severe eye irritation. Copper sulphate pentahydrate biocides are harmful if swallowed and cause serious eye damage; tetracopper hexahydroxide sulphate and its hydrate is harmful if swallowed; Bordeaux mixture (another copper biocide); and copper (I) oxide-based biocides are harmful if inhaled and cause serious eye damage. The committee agreed that copper thiocyanate biocides are very toxic to aquatic life.

Meanwhile, ECHA's biocidal products committee has approved the use of 5-Chloro-2-(4-chlorophenoxy)-phenol (DCPP) as an active substance for biocides used in the EU. DCPP is used to make liquid hand soaps and surface disinfectants.

ECONEA RECEIVES POSITIVE APPROVAL FOR BPR

 Press Release: January 2015

Janssen PMP, a division of Janssen Pharmaceutica NV, has announced that the EU Standing Committee on Biocidal Products has voted positively for the approval of ECONEA™ (tralopyril) under the EU Biocidal Products Regulation 528/2012 (EU BPR), for use as a new active substance for "Product Type 21", which encompasses antifouling products.

"It has been a long journey but we are extremely pleased with the positive outcome of the review process for tralopyril under the EU BPR, a regulatory regime which is recognized for having some of the highest environmental and human health risk assessment standards in the world" said Dr Adrian Gray, Janssen PMP's European Regulatory Manager. "Following this positive Standing Committee vote, publication of the EU Commission implementing regulation for the approval of tralopyril is expected to open the door for applications for authorizations of antifouling paints containing ECONEA™ in the European Economic Area."

Tony Kempen, Global Product Manager Microbial Control for Janssen PMP, added: "Since the shipping industry is a truly global industry, it has always been our strategic objective to support ECONEA™ under the various regulatory regimes worldwide. Following registrations in the USA, China, South Korea, Japan and a host of other countries in different parts of the world, this landmark EU BPR approval makes ECONEA™ the first and hitherto only copper alternative which has regulatory approvals in all major antifouling markets around the globe."

About ECONEA™

ECONEA™ represents the latest generation of active substances for use in antifouling paints to prevent the settlement of unwanted aquatic organisms on ship hulls and other marine structures. Depending on the paint formulation, ECONEA™ is as effective as cuprous oxide at about one tenth the use concentration in the paint by weight. ECONEA™ is supported with extensive toxicological and environmental databases as well as approvals by regulatory authorities throughout the world. More information can be found at www.econea.com.

KOPPERS ACQUIRES KMG’S CREOSOTE BUSINESS

 ICIS: January 2015

Koppers is getting out of the utility pole business in the U.S. and acquiring another chemicals business. The company has reached agreement to sell its U.S. utility pole business to Cox Industries of Orangeburg, S.C., for an undisclosed price. The business had revenues last year of approximately $43 million.

The sale does not include Koppers' wood treating plant in Florence, S.C., which is its main production facility. Koppers said it will retain that plant to supply wood treatment products for railroad crossties and other railroad products.

Tom Loadman, vice president of Koppers' railroad and utility products and services segment, said divesting the utility pole business "was the best long-term alternative for Koppers" as the company focuses more on growing its railroad maintenance division. The company will continue to operate its utility pole business in Australia "and expect that it will continue to remain a part of Koppers for many years to come," said Leroy Ball, Koppers' president and chief executive.

Separately, Koppers said it has acquired the creosote distribution business of KMG Chemicals in a deal KMG valued at $15.5 million. Creosote is a substance produced by tar distillation that is used as a wood preservative for railroad crossties. The transaction includes $12.5 million in cash and inventory with an estimated value of $3 million. KMG, a specialty chemicals company based in Houston, said its creosote assets "are more strategically advantageous for Koppers."

The acquired creosote business will be part of Koppers' carbon materials and chemicals segment, which has faced weak market conditions lately.

GE INTRODUCES INDUSTRIAL COOLING WATER BIOCIDE

 WaterTech: January 2015

GE has introduced a new biocide for industrial cooling water systems designed to reduce microbiologically influenced corrosion and the potential risk of Legionella bacteria. GE's Spectrus TD1100E is a non-oxidising microbiological control agent used to kill or control growth of microbial populations in open evaporative cooling systems.

Cooling water systems are essential to production in many industrial plants and for comfort cooling in commercial and institutional facilities. Corrosion and microbiological fouling must be kept at bay to avoid damage to equipment and system inefficiencies, which can result in losses in production and / or excessive water and energy consumption. In addition, microbiological growth that is not tightly controlled can result in increased employee and community exposure to health risks including Legionnaires' disease.

The Spectrus TD1100E is a unique liposome-enhanced biocide that directly targets biofouled surfaces within the cooling system and / or the tower pack with less chemical handling and a lower environmental footprint. It also improves heat transfer rates, increases efficiency, reduces the amount of chemicals, which lowers environmental impact, and diminishes adsorbable organic halogens in effluent water. Sessile bacteria (biomass) is also reduced, thereby addressing a key risk factor for Legionella development on a cooling system.
