Definitions
- the present invention relates to the use of solid form nitrogen-containing cosurfactants to enhance the primary detergency of laundry detergents when washing fabrics against oil and / or greasy soils.
- detergents In addition to the ingredients indispensable for the washing process, such as surfactants and builders, detergents generally comprise further constituents which can be summarized under the term washing assistants and which comprise such different active ingredient groups as foam regulators, graying inhibitors, bleaching agents, bleach activators and dye transfer inhibitors.
- washing assistants Such excipients also include substances whose presence enhances the detergency of surfactants, without them usually having to exhibit a pronounced surfactant behavior itself. The same applies mutatis mutandis to cleaners for hard surfaces. Such substances are often referred to as a detergency booster or because of their particularly pronounced effect against oil or fat-based stains as a "fat booster".
- nitrogen-containing cosurfactants improve the primary washing performance against grease / pigment containing soils; but as a rule they are liquid or paste-like at room temperature, but they can be difficult to formulate into particulate detergents and cleaners.
- the invention which seeks to remedy this, is in a first aspect, a granulate, which 10 wt .-% to 90 wt .-% nitrogen-containing cosurfactant, 10 wt .-% to 90 wt .-% of carrier material and up to 50 wt % Binder.
- granulate in the context of the present invention includes granules in the narrower sense, agglomerates, powders, coated particles, PrNIs, etc.
