F O C U S Phosphates and replacements Synthetic zeolite: exploring new applications Research and development into new applications for synthetic zeolites is ongoing. Until recently, most synthetic zeolites were used as detergent builders, a market of 140,000 tonnes/y and accounting for 90% of demand. Consumption of synthetic zeolites for detergent builders (sodium aluminosilicate) amounted to 88,524 tonnes in 1999 and 81,450 tonnes in 2000. Production fell 17% in 2000 to 45,880 tonnes. Details are given of the latest innovations in synthetic zeolites. Japan Chemical Week, 4 Apr 2002, 43 (2166), 6-7
Perborates FMC plans to build 35,000 tonnes/y of sodium percarbonate capacity at its site at La Zaida, Spain As a consequence of the detergent market trend towards sodium percarbonate, FMC Foret is switching part of its sodium perborate capacity at La Zaida, Spain, to percarbonate. FMC Foret has already had a 15,000 tonnes/y percarbonate plant in operation since Dec 2001. The switch will make a further 35,000 tonnes/y available by 2H 2003.

ENZYMES Novozymes rolls out new lipase for cold wash temperatures Novozymes has launched Lipex (lipase, active at 20C, can be used with linear alkyl benzenesulfonates) into the detergent enzymes market. Product launch is imminent in the USA and due in Europe in 2H 2002. Novozymes sales of technical enzymes fell 3% in 2001 due to competition and pricing pressure. The company plans to launch new proteases and cellulases into the detergent enzymes market. Chemical Market Reporter, 29 Apr 2002 (Website: http://www.chemexpo.com/cmronline)

PATENTS Henkel receives low-concentration, highly viscous liquid detergent patent Henkel has obtained patent number 6,342,472 for low-concentration, highly viscous liquid detergents. The detergents offer a maintained storage viscosity property under various weather conditions, maintained colour property under light exposure and no phase or agglomerate separation. Soap and Cosmetics, Mar-Apr 2002, 78 (2), 48
Cognis receives cosmetic formulations patent Cognis has obtained patent number 6,306,421 for cosmetic compositions like skin cleansers. The formulation contains about up to 80% oil by weight and approximately 20%-80% of one or more ethoxylated partial glycerides by weight. The formulation also contains additives and/or cosmetic auxiliaries, and water. The produced cosmetic products spread smoothly and easily, and transparent when applied on the skin. Soap and Cosmetics, Mar-Apr 2002, 78 (2), 28
Kao patents granular detergents Kao Corp of Tokyo, Japan, has obtained patent number 6,335,313 B1 for detergent granules composed of a nonionic surfactant and crystalline alkali metal silicate with iron content of 140 ppm or less. HAPPI, Household & Personal Products Industry, Apr 2002, 39 (4), 28
Rohm and Haas receives aqueous composition processing patent Rohm and Haas has obtained patent number 6,337,366 for a process that enhances viscosity of an aqueous composition. The method stabilizes the viscosity of aqueous compositions containing at least one associative thickener and high levels of surfactants. The composition produced also contains a mixture of at least one monophobe and at least one multiphobe.
BASF receives cleaning formulation patent BASF has obtained patent number 6,342,474 for an aqueous hard surface cleaning formulation. The formulation contains an effective amount of cleaning auxiliary, a nonionic surfactant, a water-soluble organic solvent and an optional thickening agent. The formulations can easily wipe off or scrub off hard surfaces. Soap and Cosmetics, Mar-Apr 2002, 78 (2), 28
Unilever patents hair styling compositions Researchers for Unilever Home & Personal Care USA have been awarded patent number US 6,335,000 Bi for a hair styling formulation that includes a crosslinked silicone polymer, a surfactant, cationic hair styling polymer, water and an aerosol propellant.

Dial Corp receives process patent
L’Oreal patents nanoemulsion
Dial Corp has obtained patent number 6,310,015 for a process and composition of a transparent, moisturising and translucent cosmetic or personal cleansing bar. The bar preferably contains approximately 7%-11% water, and approximately 13% by weight or less of final water. The product does not easily melt and deform, and has higher durability and hardness.
Researchers for L’Oreal have obtained patent number US 6,335,022 B1 for a nanoemulsion that can be utilised in dermatological, cosmetics and/or ophthalmological fields. The nanoemulsion is produced from an oil phase dispersed in an aqueous phase and contains one or more oils, a surfactant and one or more amphiphilic lipids.
