Abstract: The present invention relates to activated and ground sodium hexametaphosphate frit particles and antimicrobial composite material comprising said activated and ground sodium hexametaphosphate frit particles embedded in a thermoplastic polymer such as low density polyethylene (LDPE). The invention also relates to the method for obtaining the composite material of the invention and a thermal activation method for the thermal activation of a sodium hexametaphosphate salt in order to generate the activated and ground sodium hexametaphosphate frit particles. The antimicrobial material of the invention is preferably used in the food industry.

Abstract: Natural oil based marking compositions and their methods of making are provided. The compositions comprise a lipid-based wax having approximately 0-90 percent by weight triacylglycerides and approximately 10-99 percent by weight monoacylglycerides and diacylglycerides combined. The compositions also comprise approximately 1-40 percent by weight of a structuring agent. The methods comprise blending the composition by heating the lipid-based wax and structuring agent at a sufficiently high temperature to destroy substantially all crystal structure within the lipid-based wax. The methods further comprise pouring the composition into a mold having a surface and a core, wherein the pouring is conducted at a temperature at least 5° C. greater than the congeal point of the lipid-based wax. The methods further comprise cooling the lipid-based wax under conditions sufficient to cool the core to at least 5° C. below the congeal point of the lipid-based wax in approximately 30-90 minutes.

Abstract: The invention provides a process for producing a crayon having a desired hardness stably without poor gelation using a benzylidene sorbitol gelling agent together with the use of carbon black as a black pigment. The process comprises: dissolving and dispersing a resin component, carbon black having a pH of less than 5.0 and an organic amine in an organic solvent, dissolving at least one gelling agent selected from the group consisting of dibenzylidene sorbitol, tribenzylidene sorbitol and derivatives thereof in the resultant under heating to prepare a raw material solution, pouring the raw material solution into a molding container, and cooling and gelling the raw material solution.

Abstract: There is provided a transparent solid marker that has high bending strength and low writing resistance as stick-formed goods, is difficult to break or bend, generates few remnants while coating is carried out, and does not cause spreading of a writing surface even if it is coated on a surface which is written on by oily or aqueous writing implements. There is provided a transparent solid marker that is obtained by heating and mixing a composition including a gel forming material that includes an alkali metal salt or ammonium salt of an aliphatic carboxylic acid having 8 to 36 carbon atoms, a transparency agent, a subsidiary transparency agent, hydrogenated glucose syrup, a basic pigment, and oil, and cooling it.

Abstract: A solid drawing material containing a gel-forming substance of an alkali metal salt or an ammonium salt of an aliphatic carboxylic acid having 8 to 36 carbon atoms, an alkoxylated nitrogen-containing compound, a reduced starch saccharide, and a coloring agent. The solid drawing material which is in the form of a stick features a large strength, a small drawing resistance, is less subject to be collapsed or broken, produces little shavings while drawing, makes it possible to favorably form a drawing even on smooth surfaces such as windowpanes, and of which the traces after drawn can be easily wiped out with a wet cloth.

Abstract: The invention provides a crayon comprising an organic solvent, a resin soluble in the organic solvent, a coloring agent, a gelling agent and an interferential pearl luster pigment. The crayon provides a metallic or pearly coating film, and has characteristics such that the color tone of the coating film varies with an angle for viewing the coating film, namely, a visual angle for the coating film. Therefore, for example, when applied to a flaw caused in metallic or pearly coating of automobiles, the crayon is adapted to such coating of automobiles to form an integrated coating film, so that it is suitably used for repairing such a flaw.

Abstract: A solid marking composition comprises a solid matrix containing at least one type of optically variable interference pigment flakes. The solid marking composition provides a document or article with a copy and counterfeit protection feature, and is preferably used in a writing instrument for applying hand-written anti-counterfeit markings and signatures.

Abstract: A multi-color crayon or oil pastel which features excellent drawing property, vividness of color and intimate adhesion of multi-color picture in combination, and a method of preparing the same. The multi-color crayon or oil pastel comprises a continuous matrix of a crayon or oil pastel material and a plurality of kinds of granular coloring phases dispersed in the matrix, the granular coloring phases being formed of a collapsible granular material which includes a coloring matter of a hue different from that of the continuous matrix, a body, and a water-soluble or solvent-soluble high molecular material or a water-swelling clay mineral (e.g., bentonite).

Abstract: A solid glitter marker comprising a gel-forming material that contains (A) at least one kind of gelling agent selected from the group consisting of a dibenzylidene sorbitol, derivatives thereof, tribenzylidene sorbitol and derivatives thereof, (B) water, (C) a water-miscible organic solvent, (D) a high0molecular adhesive and (E) a glitter, the gel-forming material having a bending strength under JIS S-6026 of 160 to 700 g and a crushing strength which is not larger than 10 times as large as the bending strength.
