DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

(2) The present invention provides for a starch-based moldable play composition, including: 55% by weight corn starch; 8% by weight mineral oil; 5% by weight propylene glycol; 8% by weight glyceryl stearate; 10% by weight sodium laureth sulfate; 3% by weight sodium chloride; 0.5% by weight potassium sorbate; 0.5% by weight phenoxyethanol; 9.12-9.63% by weight water; 0.15% by weight fragrance; and 0.1-1.0% by weight pigment dye, selected from the group consisting of yellow 3, yellow 4, red 14, red 17, blue 1, blue 2, and titanium dioxide.

(3) Starch is an essential ingredient of the moldable play composition and can include corn starch, wheat starch, rice flour (glutenous and non-glutenous), potato starch, or tapioca starch.

(4) Starch granules are made of polysaccharides (strings of sugar molecules) which include both amylose, a linear polysaccharide molecule, and amylopectin, a branched polysaccharide molecule that is formed by hydrogen bonds between the strands. Starches with a higher percentage of amylose make a stronger, firmer dough. Preferable starches have a sufficient amylose content to create a firm, yet moldable soap composition.

(5) In the present invention corn starch was preferably used to make the moldable soap composition. The preferred weight percent of corn starch is 55% of the moldable soap composition. However starches, selected from the group consisting of: corn starch, wheat starch, rice flour (glutenous and non-glutenous), potato starch, or tapioca starch can also be used.

(6) The corn starch is added to water which is preferably from 9.12% to 9.63% by weight of the moldable soap composition.

(7) However, over time, the amylose strands in the starch- and water mixture begin to bind to each other which is called retrogradation. Retrogradation of the starch in the moldable soap composition results in it drying out and hardening. Accordingly, a retrogradation inhibitor or humectant is further added to the mixture which helps prevent retrogradation of the starch and helps soften the moldable soap composition. Preferably, propylene glycol is added to act as a retrogradation inhibitor and softener and is preferably 5% by weight of the moldable soap composition.

(8) In addition, lubricants are added to further improve the texture and consistency of the moldable soap composition and to reduce the stickiness of the moldable soap. Preferably, mineral oil is added to the composition at 5% to 10% by weight of the moldable soap composition. Furthermore, glyceryl stearate is added to the composition to act as a surfactant and emulsifier to further improve the moisture and viscosity of the moldable soap. Preferably, glyceryl stearate is 8% by weight of the moldable soap composition.

(9) Furthermore, a foaming agent is added to the mixture to facilitate the formation of foam, act as a detergent and a surfactant, and to further reduce the stickiness of the moldable soap on the hands of the user. Preferably, sodium laureth sulfate is used as a foaming agent. Sodium laureth sulfate (SLES), an accepted contraction of sodium lauryl ether sulfate (SLES), is an anionic detergent and surfactant found in many personal care products (soaps, shampoos, toothpaste etc.). It is an inexpensive and very effective foaming agent. The percentage of sodium laureth sulfate used is preferably 10% by weight of the moldable soap composition.

(10) Salts are also added to the moldable soap composition which further stiffens the composition by reducing its moisture, preserves it, and adds some antimicrobial properties to the composition. Preferably, sodium chloride is added to the composition at 8% by weight of the moldable soap composition.

(11) Additional preservatives are also added including potassium sorbate and phenoxyethanol. Specifically, potassium sorbate and phenoxyethanol are both added to the composition in amounts from 0.1% to 1.0% by weight of the moldable soap composition.

(12) In order to make the moldable soap composition more appealing to the user, fragrances and dyes are also added. Specifically, fragrances are added to the composition at 0.1% to 1.0% by weight of the moldable soap composition. Also, pigment dyes, selected from the group consisting of yellow 3, yellow 4, red 14, red 17, blue 1, blue 2, and titanium dioxide, are also added in amounts from 0.1% to 1.0% by weight of the moldable soap composition.

(13) Thus, the present invention provides a safe, non-toxic, and non-irritating, moldable soap composition that has improved moldability, is soft, and maintains structural integrity even after it is exposed to water. Further, the present invention provides a play moldable soap composition that remains moist, soft, and is easily moldable while retaining its structural integrity such that it can be cleanly cut into pieces, molded into various shapes, and can be put through an extruder. In addition, the play moldable soap of the present invention doesn't leave a powdery residue in the hands of the user, can be molded and cut into shapes whether it is wet or not, and is reusable and soft even after it is wet and until it disappears.

(14) In the specification the terms comprise, comprises, comprised and comprising or any variation thereof and the terms include, includes, included and including or any variation thereof are considered to be totally interchangeable and they should all be afforded the widest possible interpretation.
