Wacker showcases innovative silicone-based antifoam at SEPAWA 2009
F O C US detergents for the washing industry (3.4 M tonne/y), textile dyeing and printing (1.2 M tonne/y), the glass industry (1.3 M tonne/y), and for sodium sulfide production (2.2 M tonne/y). China has abundant resources of mirabilite, the main raw material for sodium sulfate, with proven reserves of 17.78 bn tonnes and total resources of up to 30 bn tonnes. Chinese imports and exports of sodium sulfate during 2001-2008 are compared. In 1H 2009, sodium sulfate exports totalled 1.325 M tonnes compared with imports of just 307 tonnes. Chinese production of sodium sulfate rose to around 8.2 M tonnes in 2006. The largest Chinese producer, China Nafine Group International Co Ltd with a capacity of more than 2 M tonne/y, expects to account for 25% of the 3.5 M tonnes of exports in 2010. Problems faced by Chinese sodium sulfate producers include overcapacity and low product quality.

formulations are possible. It is also a suitable general-purpose foam-control additive for other powder products that foam when applied or when they dissolve, such as granular cleaning and plant-protection agents. The antifoam is easy to use. In most cases, 0.5% to 2.5% Silfoam SP 150 is sufficient. If a particularly exact or very low dosage is required, the product can be mixed with sodium sulfate or another carrier beforehand. Silfoam SP 150 has a long shelf life. When the agent is stored in its original container at max 30°C, its effectiveness will not diminish, even after 12 months.

Wacker showcases innovative silicone-based antifoam at SEPAWA 2009
Cognis at SEPAWA 2009: holistic product experiences and a high level of naturalness
Wacker, the Munich-based chemical company, showcased an innovative silicone antifoam agent for powder detergents at the 56th SEPAWA Congress in Würzburg, Germany, from 14 to 16 Oct 2009. Marketed as Silfoam SP 150, this white powder additive efficiently regulates foaming within a very broad temperature range. It also exhibits excellent flow and processing properties, combined with a high bulk density. Silfoam SP 150 was formulated without starchbased additives, making it highly versatile. The silicone antifoam powder inhibits foam formation persistently and extremely efficiently. Its action is largely unaffected by temperature: effective foam control begins right in the low-temperature range and is not impaired by high temperatures either. Silfoam SP 150 is therefore ideal both for lowtemperature detergent formulations and general-purpose detergents. Versatile and flexible, the new product can be used as an antifoam agent on its own or with soap. Combinations of the antifoam agent with a broad variety of different powder detergent
At the 56th SEPAWA congress in Würzburg, Germany in Oct, speciality chemicals supplier Cognis presented its latest solutions for ‘green’ and high-performance personal care and home care products. Company experts gave a number of presentations explaining how manufacturers can use its ingredients and concepts to effectively serve the needs of today’s consumers. Cognis exhibited a number of new ingredients for manufacturers of cosmetics as well as detergents and cleansing products at SEPAWA 2009. These included a high-performance anionic O/W emulsifier, which is highly effective even at low concentrations, and can be used in a wide variety of advanced skincare formulations. In particular, its outstanding electrolytic and pigment stability mean it is ideally suited to use in sun protection products. A PEG/EO-free dispersion polymer designed for skin and hair care products, with an excellent sensory profile, gives a very pleasant skin and hair feel and improves the combability of wet and dry hair.

introduction is a transparent microemulsion that fits with the ‘green’ trend in the shampoo segment by combining natural origins with excellent performance. It is made entirely from plant-derived raw materials, and delivers outstanding conditioning. The company also presented a high-performance wax dispersion consisting of a system that provides proven protection against hair breakage when used in shampoos, as well as excellent conditioning benefits in both skin cleansing and hair cleansing products. For hard surface cleaners, Cognis highlighted a new additive that provides visible benefits for the consumer, such as spotless drying, easy-to-clean-again effect and streakfree cleaning without residues. Its ecotoxicological profile and excellent aerobic and anaerobic biodegradability make it ideally suited for use in ‘green’ formulations and those with an eco-label. The company also promoted its Green Formulation Set and Green Chemical Solutions (GCS) concepts [Focus on Surfactants, Mar 2009 & Nov 2007], which rate the naturalness of formulations and individual chemicals in Cognis’ portfolio, respectively.
