Embodiment Construction

[0033] Two formulations, the inventive formulation (1 ) and the comparative formulation (V1 ) were evaluated in terms of stability and whiteness. Whiteness is measured according to the method of DIN EN 12625-7, item 7.3.2, color (D65 / 10°), where the whiteness of uncoated / unimpregnated paper is taken as 100%. Evaluate the reduction in whiteness, expressed in %, where a reduction of not more than 4% is permitted. The sensory properties were evaluated by trained personnel according to the principle of a 1-6 point scoring system.

Abstract

Water-in-oil emulsion comprises: polygylcerin-2-dipolyhydroxyste arate (12-21 wt.%); hydrogenated ethoxylated ricinus oil (4-7 wt.%); mineral oil (25-35 wt.%); further oil body (20-30 wt.%); hydrotropes (3-5 wt.%); metal soaps (3-4 wt.%) and water (10-30 wt.%).

Description

technical field [0001] The subject of the present invention are specific emulsions which can be used for impregnating and wetting commodity and toilet paper / towels. technical background [0002] The general concept "paper" refers to about 3000 different types and articles whose properties and fields of use vary widely in some cases. Many additives are needed to produce paper, the most important of which are fillers (such as chalk or kaolin) and binders (such as starch). In the area of ​​tissue and toilet paper, which come into close contact with the human skin, there are particular demands on pleasant softness. For paper, lightness is usually achieved through careful selection of fibrous materials, especially the use of high levels of virgin wood pulp or cellulose. However, considering the economics of paper production and from an environmental point of view, it is desirable to use as high a content as possible of low-quality waste paper. However, this has the consequence...
