DETAILED DESCRIPTION

[0017] In embodiments of the disclosure, a modeling compound includes a base compound and dehydrated particles admixed with the base compound. In embodiments, the dehydrated particles are a starch-based compound that is capable of mixing with the base compound when the modeling compound is manipulated. In embodiments, the dehydrated particles rehydrate from moisture present in the base compound. In embodiments, the dehydrated particle rehydrate and remain as discrete particles, maintaining or substantially maintaining their original shape until the modeling compound is manipulated. For example, manipulation can be that of a typical play pattern of modeling compounds such as Play Doh^®. For example, the modeling compound, can be stretched, squished, twisted, and/or mechanically shaped or moved in any other way, which can initiate and/or further mechanical blending of the particles into the base compound, thereby destroying the original shape of the dehydrated particles. In some embodiments, such manipulation results in color blending between the particles and the base compound, resulting in a color changing composition upon manipulation and further

manipulation, as shown in Figures 1 A to 1 D.

[0018] In embodiments, the modeling compound can be a color changing compound. For example, the base compound can have a first color and the dehydrated particles can have second color, different from the first color. In embodiments, the first color of the base compound and the second color of the dehydrated particles do not or substantially do not intermix until the modeling compound is manipulated. As illustrated in Figures 2A and 2B, for example, upon manipulation, for example, the two colors can be intermixed, thereby resulting in a modeling compound having a third color, different from the first and second colors.

[0019] Referring to Figure 3, when the base compound and the dehydrated particles have colors selected to provide a color change, the extent of the color change or incorporation of the color of the dehydrated particles into the base compound can be controlled by the amount of manipulation. For example, the manipulation can be such that some base compound color remains and a swirl or marbling type effect is provided as is illustrated in Figure 3. In embodiments, the modeling compound can be manipulated to fully incorporate the particles into the base compound to provide a single uniform compound of a different color, such as is shown in Figure 1 D.

[0020] In some embodiments, the colorant of the dehydrated particles can be selected such that there is at least some color migration of the dehydrated particles colorant when the dehydrated particles are mixed into the base compound in making the modeling compound and/or when the dehydrated particles being to rehydration and/or a duration of storage time.

The weight percentages recited in this paragraph being by weight of the total weight of the composition of the particles prior to dehydration.

[0049] Any combinations of formulations of the base compound and the dehydrated particles can be used. For example, in embodiments, the base compound and the dehydrated particles (prior to dehydration) have the same formulation. In embodiments, the base compound and the dehydrated particles (prior to dehydration) can have the same formulation except for the colorant used. In embodiments, the base compound and the dehydrated particles (prior to dehydration) can have the same formulation except additional water is added to the base compound. In embodiments, the base compound and the dehydrated particles can have different formulations. In embodiments, the base compound can have one or more additives, such as glitter, colored cotton, microspheres, and other additives, which are not included in the dehydrated particles. In embodiments, the dehydrated particles can have one or more additives, such as glitter, colored cotton, microspheres, and other additives, which are not included in the base compound. In embodiments, the additives can be included in an amount of about 0.1 to 5%, about 0.5% to 2%, about 1% to 3%, and about 0.8% to about 1.2%, by weight of the base compound.

[0050] In embodiments, the dehydrated particles are formed by drying the composition to a water loss of about 20% to about 50%, about 20% to about 40%, about 30% to about 40%, about 34% to about 38%. Other suitable moisture contents, as measured by water loss on drying, include about 20, 22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, and 50%. It has been advantageously found that such drying of the dehydrated particles allows for incorporation of the dehydrated particles into the base compound while maintaining the discrete shape of the dehydrated particles.

[0051] It has been further found that such dehydrated particles can rehydrate from moisture present in the base compound. Rehydration can occur, for example, during storage of the modeling compound. In embodiments, the dehydrated particles can maintain or substantially maintain the original discrete particle shape upon rehydration prior to use (e.g., manipulation or play) of the modeling compound.

[0052] Upon manipulation of the modeling compound, the rehydrated particles can incorporate into the base compound, which thereby destroys the discrete particle shape and blends the particles into the base compound. In embodiments, colors of the base compound and the dehydrated compound can blend together resulting in a color change of the modeling compound if the base compound and the dehydrated compound are of different colors or shades of colors.

[0053] In embodiments, the dehydrated particles can be adapted to rehydrate only upon manipulation of the modeling compound. For example, the dehydrated particles can include a coating or encapsulation that prevents moisture transfer into the particles during storage in the base compound. The coating or encapsulation can be broken with mechanical manipulation of the modeling compound, thereby allowing moisture to interact with the composition of the dehydrated particles resulting in rehydration and subsequent incorporation of the particles into the base compound upon further manipulation of the modeling compound.

[0054] The dehydrated particles can have any desired shape and/or size and/or colors. For example, the dehydrated particles can have a cross-section that is one or more of circular, square, rectangular, elliptical, hexagonal, diamond, and heart. In embodiments, the dehydrated particles can have other shapes, such as dog bones, or can be mimic the shape and/or size of an object, such as chocolate chips in dough or ice cream. The dehydrated particles can have a length and/or width of about 0.1 mm to about 10 mm. In embodiments, the dehydrated particles can have a diameter or width of at least about 3 mm, about 3 mm to about 10 mm, or about 3 mm to about 5 mm. The dehydrated particles can have a uniform size and/or shape.

Alternatively, the dehydrated particles can have a mixture or variety of sizes and/or shapes.

[0055] In embodiments, the composition for forming the dehydrated particles can be dried by heating in an oven to the desired loss of moisture. For example, the composition can be dried at a temperature of about 70 °C to about 100 °C. The composition can be dried by heating for any suitable amount of time to achieve the desired loss of moisture. For example, the composition can be dried for about 10 minutes to about 90 minutes, about 20 minutes to about 60 minutes, about 30 minutes to about 50 minutes, and about 20 minutes to about 45 minutes. Other suitable times include about 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, and 90 minutes. Other times are contemplated herein and may vary depending on the drying conditions.

[0056] In embodiments, the composition for forming the dehydrated particles can be dried by freeze drying process.

[0057] In embodiments, the composition forming the dehydrated particles can be shaped in to the discrete particle shapes prior to drying. In alternative embodiments, the composition can be dried and then cut or otherwise formed into the discrete shapes. EXAMPLES
