Description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] The invention is further described in detail hereinafter with reference to the embodiments.

[0019] A coloured slimysand comprising following raw materials in percentage by weight:

TABLE-US-00002 silicon dioxide 70%-88% water  5%-10% phenyl silicone oil 1%-5% mannitol 1%-3% white granulated sugar 1%-5% adhesive  2%-10% preservative 0.2%-1.3% pigment 0.1%-0.5%

[0020] Said silicon dioxide selected is penetrating porous one after going through smoothing treatment and can be purchased on the market directly. Using penetrating porous silicon dioxide can not only reduce the weight of the slimysand, but also increase surface area of contact surface between the silicon dioxide and the adhesive, thus remarkably increasing adhesion of the adhesive; Adding mannitol and white granulated sugar in ingredients have strengthened stringiness of the adhesive and further improve tensile capacity of the slimysand, which can reduce the risk of slimysand's braking in the process of stretching and enhance fun of playing. The adding of mannitol can increase moisturizing property of the slimysand.

[0021] The pigment adopted is blue No. 1, yellow No. 5, and red No. 40 and other FDA approved pigment.

[0022] The particle size of said silicon dioxide is in 80-120 mesh.

[0023] Said adhesive is the mixture of two or more of polyvinyl alcohol, polyacrylamide, polyvinyl acetate and polyvinylpyrrolidone.

[0024] As the mixture of two or more of said elements, said adhesive has combined features, advantages and disadvantages of different adhesive to achieve better effect, among which the mixture of polyvinyl alcohol and polyacrylamide is preferred.

[0025] Said preservative is the mixture of two or more of phenoxyethanol, caprylyl glycol, ethylhexylglycerin, sodium dehydroacetate, and sodium ethylparaben.

[0026] As the mixture of two or more of said elements, said preservative has combined features, advantages and disadvantages of different preservative to achieve better effect, among which the mixture of phenoxyethanol and caprylyl glycol is preferred.
