ROKAnol LK2 is a non-ionic surfactant belonging to the group of ethoxylated fatty alcohols (INCI name: Laureth-2.) The product co-creates a group of surfactants based on lauryl alcohol. It differs from ROKAnol L2 (INCI name: Laureth-2) in its reduced water content (max. 0.1%), so it is mainly used as a semi-finished product for the production of anionic surfactants from the group of lauryl ether sulphates (SLES).
It has the form of a transparent or cloudy liquid, which over time becomes clear at the top and cloudy with sediment at the bottom. It has a maximum colour of 50 HU at 40°C. ROKAnol LK2 is slightly soluble in water, in which it forms cloudy solutions. The commercial product contains more than 99.9% of the active substance and solidifies at a temperature of approx. 0°C. Compared to other ROKAnol L series, it has a low HLB value.
In addition to being used in the sulfation process, ROKAnol LK2 can be an ingredient in cosmetic formulations. In shampoos, shower gels, bath lotions and other rinsable cosmetics, it acts as a washing agent and rheology modifier (thickener). It also shows the ability to solubilize a wide range of perfumes and active ingredients.
ROKAnol LK2 is used in various types of preparations for washing, cleaning and laundering. Most often it is one of the constituents of the composition in combination with other non-ionic, anionic or cationic surfactants. ROKAnol LK2 can be used in the oxidizing, reducing and hard water environments. It is active in acidic, neutral and diluted alkaline baths.
In addition, it is used in the pre-treatment of fibres as a component of the formulation for removing mineral oil stains from knit and woven fabrics resulting from industrial knitting and weaving processes. It can also be used in the final stage of textile processing, i.e. in finishing preparations improving the functional properties of the fabric.
ROKAnol LK2 has no foam-forming properties, however, it is characterized by excellent detergency, emulsifying and dispersing properties. It is biodegradable in the natural environment.
