Wax-based compositions

Abstract

A composition for use on personal hygiene articles containing: (a) a primary wax or oil component selected from the group consisting of a C14-30 dialkyl carbonate, a C14-30 dialkylene carbonate, and mixtures thereof; and (b) up to about 10% by weight of water, and wherein the composition has a melting point above about 25° C.

Description

[0001] This invention relates to special wax-based compositions which may be used as a basis for cosmetic preparations and, more particularly, for impregnating and wetting utility and sanitary wipes used for personal hygiene and body care.PRIOR ART[0002] The generic term "paper" encompasses about 3,000 different types and articles which can differ, sometimes considerably, in their applications and their properties. Their production involves the use of numerous additives among the most important of which are fillers (for example chalk or kaolin) and binders (for example starch). For tissues and hygiene papers, which come into relatively close contact with the human skin, there is a particular need for an agreeable soft feel which is normally given to the paper by careful selection of the fibers and, in particular, by a high percentage of fresh mechanical wood pulp or cellulose. However, in the interests of economic paper manufacture and from the ecological perspective, it is desirabl...

Benefits of technology

[0012] The presence of special oil or wax components selected from dialkyl(ene) ethers, dialkyl(ene) carbonates, dicarboxylic acids or hydroxyfatty alcohols or mixtures thereof enables the sensory properties in particular of the wax-like compositions to be optimized so that they feel less greasy and, instead, have a dry feeling on the skin, but still show excellent care properties. The compositions according to the invention contain less than 10% by weight water, preferably less than 6% by weight water and more particularly less than 3% by weight water. In a particularly preferred embodiment, the compositions are water-free. Water-free in the context of the invention means that the compositions may have a small water content originating from their raw materials, but do not contain any added water. In the processing and application of the composition to the wipes, the wipes can thus be aftertreated with aqueous / surfactant-containing solutions without the composition dissolving.

Problems solved by technology

Unfortunately, this means that the softness of the paper is significantly reduced which is troublesome in practice and can even lead to irritation of the skin, particularly with frequent use.

The coatings in use at present often leave the skin feeling too greasy and, in some cases, are distinguished by an overly slow release of active ingredients.
