Description

The The present invention relates to a particular nonionic surfactant Spray drying product, which in particular 0.5 to 5 Wt .-% of an ethoxylated fatty alcohol with a narrow homolog distribution contains. Furthermore, it relates to a washing or cleaning agent, containing such a spray-drying product. Further concerns They use a special spray-drying process and use of ethoxylated fatty alcohol with restricted homolog distribution in the spray drying of aqueous slurries.

The protection of people and the environment is in the general interest and is promoted worldwide by numerous laws. One aspect to pay particular attention to is industrial emissions. In Germany z. B. the Federal Immission Control Act with the protection against harmful environmental effects of air pollution. The so-called "Technical Instructions for Air Pollution Prevention" (TA Luft) is a general administrative regulation of the German Federal Government on the Federal Immission Control Act. It contains limits for the emission and immission of pollutants. Chapter 5 describes requirements for precautionary measures against harmful environmental effects. In particular, it is stipulated under 5.2.5 that organic matter in the exhaust gas must not exceed the total mass concentration 50 mg / m ³ , in each case given as total carbon. This requirement is important for the spray-drying production of detergents. The use of nonionic surfactants, in particular ethoxylated fatty alcohols, in the spray drying leads to an increase of the organic substances in the exhaust gas, so that z. B. the above mass concentration of 50 mg / m ³ can be exceeded quickly, unless the tower temperature would be lowered, thereby lowering the production capacity. From a business point of view, however, it is not desirable to reduce production output. At the same time, however, there is a need for nonionic surfactant spray drying powders, e.g. B. in order to obtain more efficient end products.

task The present invention therefore was the provision of a spray-drying product, which contains ethoxylated fatty alcohol.

The subject of the invention is a nonionic surfactant spray drying product comprising

at the ethoxylation of fatty alcohol are fatty alcohols with excess Ethylene oxide (EO) to a mixture of different homologs which from homologous fatty alcohol polyglycol ethers with different Polymerization exist, implemented. By the nature of the alkoxylation catalyst is thereby the free, unreacted alcohol and the homolog distribution significantly influenced. Usual products with high residual alcohol content and wider homolog distributions become more common through use basic catalysts (eg potassium hydroxide or sodium methylate) receive. These products are referred to as ethoxylated fatty alcohols with broad homolog distribution. A narrowing of the homolog distribution is achieved by using special catalysts (eg based on of layered silicates). The proportions of higher and in particular lower homologs and the residual alcohol content are significant compared to the broad homolog distribution reduced. The average degree of ethoxylation falls then together with the maximum in homolog distribution. These Products are also referred to as "peaked ethoxylates" and are readily available commercially. Examples for such commercially available ethoxylated fatty alcohols with narrow homolog distribution z.

The specified degrees of ethoxylation represent statistical averages that can be a whole or a fractional number for a particular product. The decisive factor is that there is a narrow homolog distribution.
