Ethanol

The production of ethanol from sugar in Europe dates back to the early 19th Century. The first molasses distilleries originated in the second half of the 19th Century in Northern Germany, which included KWST. The fermentation of alcohol continued to be developed further over thousands of years, and today it is an existential element of industrial production in many sectors.

For the production of bioethanol as a fuel additive, there is generally only a very limited concentration and purification which is essentially aimed at reducing the water content.

In the field of food, cosmetics and pharmaceutical industry very pure neutral alcohol is in high demand, as it is produced in complex multi-step rectifications and through the use of water (hydroselection). This yields an alcohol that is neutral in taste, i.e. it has no undesirable foreign odor or taste.

At 97.2%vol. ethanol with water forms an azeotrope and cannot be further concentrated by distillation. Using the so-called entrainer distillation, we remove the remaining water. The same effect is achieved by drying using a molecular sieve.

Alcohol, especially ethyl alcohol, is widely used as an active ingredient in products for skin and surface disinfection due to its excellent disinfecting and germicidal effect.

Since 1 September 2013, the new Biocide Regulation (EU) No. 528/2012 has been in force, replacing the previous Directive 98/8 EC. According to the Regulation, the active substances of a biocidal product must be listed in the so-called active substance list according to Article 95. The manufacturing and marketing companies receive the approval of an active substance by submitting a dossier to the ECHA (European Chemicals Agency).

After successful submission of the dossiers with ethanol (EC No. 200-578-6, CAS: 64-17-5) KWST is included in the list according to Article 95 and thus continues to be authorised to market the active substance ethanol as a biocide for the product categories PT1, PT2 and PT 4 of the main group 1 “disinfectants”.

Main group 1: Disinfectants

Product categories PT1 Human hygiene: The products of this product type are biocidal products used for human hygiene and applied to or in contact with the human skin or scalp mainly for the purpose of skin or scalp disinfection).

Product category PT2 disinfectants and algae control products: These products are not intended for direct application to humans or animals. Products for the disinfection of surfaces, substances, equipment and furniture not intended for direct contact with food or feed. […] Products used as an additive in textiles, fabrics, masks, paints and other objects or substances to produce treated goods with disinfecting properties.

Product Category PT4 Food and Feed Sector: Products used for the disinfection of equipment, containers, cutlery and dishes, surfaces and pipes used in connection with the production, transport, storage or consumption of food or feed (including drinking water) for humans and animals.
