ROKAnol DB11W has the form of an oily liquid or paste at room temperature, which at 30 ° C takes on a light color, i.e. 50 on the Hazen scale. It solidifies at a temperature of about 16 ° C. What’s more, it has a cloud point at a temperature of 60-64 ° C in NaCl solution (100 g / L). The product contains about 90% of the active substance. It is characterized by high hydrophilicity, perfectly dissolves in water. The product’s hydrophilic-lipophilic balance (HLB) is 13.6.

It is mainly used as a solubilizer, e.g. for fragrances in air fresheners.

ROKAnol DB11W is active in an oxidizing and reducing environment as well as in the presence of hard water. It works in cold water and shows stability in acid, neutral and diluted alkali baths. The product is distinguished by the best NaOH resistance from among the Rokanoli DB series, therefore it is recommended for applications requiring highly alkaline environments.

In addition, it is characterized by very good money, wetting and degreasing properties, therefore it can be a component of e.g. glass cleaner. In cosmetics ROKAnol DB11W is used in wet wipes, as well as in white cosmetics (e.g. in creams).

It is completely biodegradable and meets the criteria of the detergents directive.
