摘要:
Cationic polysaccharide derivatives are prepared by reacting a polysaccharide with a polycationic reagent having one polysaccharide reactive group and at least two cationic groups. Suitable reagents include polycationic alkyl, aryl, alkaryl, cycloaliphatic, or heterocyclic amines, some of which are novel compositions. The polycationic polysaccharide derivatives prepared from these reagents are useful in the manufacture of paper.
摘要:
Thermally-inhibited starches and flours are used in conventional water-based adhesives such as corrugating, cigarette, remoistenable, kraft adhesives. The starches or flours are thermally-inhibited by dehydrating the starch to anhydrous or substantially anhydrous and then heat-treating the starch or flour for a time and at a temperature sufficient to inhibit the starch and improve its viscosity stability. The starch or flour may be thermally or non-thermally dehydrated (e.g., by alcohol extraction or freeze-drying). Preferably, the pH of the starch is adjusted to at least a neutral pH prior to the dehydration.

A water resistant, starch-based, alkaline corrugating adhesive is provided having improved tack or runnability and comprises using a chemically treated or modified high amylose starch having at least 40% by weight amylose content as the raw starch component.
摘要:
An all natural, starch-based, alkaline corrugating adhesive free of formaldehyde and other crosslinking and water resistance additives and having good water resistant properties comprising an aqueous dispersion of a gelatinized carrier starch and a raw ungelatinized starch wherein the carrier starch has a total amylose content of greater than 60% by weight and the gelatinized starch amylose content is at least about 15% by weight of the total starch content in the adhesive.

摘要:
This invention details the use of a simple blend of polyvinyl formamide and one or more polyvinyl alcohols as the fixative polymer system in a clear hair gel composition. The interaction of the polymer system and gelling agents provides clarity of less than 20 NTU and other physical properties such as good curl compression, resistance to high humidity and resistance to flaking.
摘要:
The present invention relates to a hair fixative film, which contains a natural and/or synthetic polymer as the main component and a method of applying said film to hair. Such film is useful in maintaining a desired look and style of hair. Furthermore, the film is beneficial because it enables the combination of ingredients that are incompatible in other application forms.
