ROKAnol NL4 is a non-ionic surfactant from the group of ethoxylated alcohols (INCI name: C9-11 Pareth-4). The product belongs to the ROKAnol NL series based on C9-C11 synthetic alcohol. High surface activity allows them to be used mainly in detergents and cleaning agents. The commercial product contains about 100% of the active substance.
ROKAnol NL4 takes the form of a clear or slightly turbid liquid, solidifying at about -10°C. At 40°C, it takes the form of a clear liquid with a light colour, i.e. up to 100 Hazen-scale. ROKAnol NL4 exhibits poor solubility in water, forming turbid solutions. Its cloud point is at 60 ÷ 65°C in a butyl-glycol / water solution.
Due to the non-ionic nature, it works perfectly in combination with other non-ionic, cationic and anionic surface-active compounds. ROKAnol NL4 stands out from other products of the ROKAnol NL series with no foam generating capacity. In addition, it has very high detergency, emulsifying and dispersing properties. ROKAnol NL4 is perfectly suited as a co-surfactant in all types of cleaning formulations, especially in products intended for industrial and institutional applications.
The basic feature of ROKAnol NL4 is its high efficiency of degreasing hard surfaces. In combination with ROKAnol NL6 and ROKAnol NL8 it exhibits synergism in cleaning performance. Examples of such application are: degreasing agents for sheet metal and metal parts, floor cleaning products, professional products for gastronomy. ROKAnol NL4 in cleaning formulations is usually used in the presence of a hydrotrope or solvent (e.g., BDG), which improves its stability in the formulation.
ROKAnol NL4 is a completely biodegradable product and meets the criteria of the detergents directive.
