  • Efficient cleaning performance and viscosity of the cleaning compositions are two requirements which drive consumer acceptance of hard-surfaces cleaning products. Indeed, viscosity enables cleaning compositions to remain long enough on the surface to provide an effective cleaning action. Such a requirement is of particular utility in cleaning compositions intended to be applied "as is” to non-horizontal surfaces such as walls, windows and sanitary fittings such as sinks, baths, showers, wash basins and WCs.
