CAS No.:



ROKAmer 2100 belongs to the group of nonionic block copolymers of ethylene oxide and propylene oxide (ROKAmers). The product is a high molecular weight copolymer with a specific, bifunctional structure, which means it has two hydrophilic groups. This feature distinguishes the ROKAmers group from other nonionic surfactants and determines their properties. ROKAmer 2100 is among products with low and anti-foaming properties. It is dedicated for professional detergents for institutional and industrial cleaning as well as for some industrial processes.

The product is a clear, colourless liquid with a low freezing point (below 0°C) and with an active substance content of about 100%. The ROKAmer 2100 water solutions below room temperature are clear, while they become turbid at 23-27°C. The product is characterised by moderate hydrophobicity and good degreasing and wetting properties of hard surfaces. This makes it used, among others, as a component of professional dishwashing chemicals, formulations for industrial bottle washing and metal degreasing preparations.

ROKAmer 2100 is used in Clean in Place systems, e.g., as a component of cleaning formulations in breweries. Thanks to the anti-foaming properties already achieved at low temperature, it causes a lowering of the foaming of washing baths, also in the presence of proteins or starch.

ROKAmer 2100 is a product resistant to hard water, dedicated to neutral or slightly alkaline formulations. In addition, it is a reactive surfactant and it is possible to further modify it, e.g., with fatty acids. Its derivatives are anti-foaming ingredients for the paper and food industries (e.g. sugar production), as well as for numerous processes where the problem of foaming of sewage and technological waters occurs. Thanks to its properties, the product reduces the surface tension between the liquid and the air, and at the same time improves the "drainage" of the foam, resulting in its reduction. ROKAmer 2100 is also used in the agrochemical industry, mainly in EC, SC, and SE formulations.

ROKAmer 2100 does not contain silicone and is not classified as a dangerous substance. The product has a Kosher certificate. It is susceptible to aerobic biodegradation and complies with the regulations permitting the product for indirect contact with food. The US Food and Drug Administration (FDA) allows the use of this product and its derivatives as an antifoaming agent under the conditions described in the following FDA sections:

  • 173340
  • 175.105
