Modeling composition for craft works and a method for the production thereof

Claim 2

A smooth and velvety modeling composition especially adapted for handicraft articles which is soft, pliable, non-sticky, non-toxic and rapid-drying consisting essentially of a mixture having the consistency of dough and formed from at least one material selected from the group consisting of starch and grain flour which is mainly composed of starch, non-toxic synthetic latex having no offensive or irritating smell and which does not cause chapped skin, and bread crumbs having a porous structure composed of α-starch and thermally modified and solidified gluten, and containing, in addition to small amounts of astringent agent adapted to increase the gellation temperature of the starch, filler, wetting and lubricating agent, borax and other conventional additives, at least one anti-discoloring and anti-fading agent selected from the group consisting of dibutyl hydroxy toluene and butyl hydroxy-anisole.

Claim 3

A composition according to claim 1 wherein the total amount of said anti-discoloring and anti-fading agent is from 0.04% to 0.4% by weight of the total weight of said mixture, said synthetic latex being selected from the group consisting of polyvinyl acetate emulsion and polyvinyl alcohol solution.

Claim 4

A composition according to claim 1 consisting essentially of a mixture by weight of 100 parts of non-toxic synthetic latex having no offensive or irritating smell and which does not cause chapped skin, 55 to 75 parts of at least one material selected from the group consisting of starch and grain flour which is mainly composed of starch, 35 to 55 parts of bread crumbs having a porous structure composed of α-starch and thermally modified and solidified gluten, 1 to 2 parts of astringent agent adapted to increase the gellation temperature of the starch, 3 to 6 parts of wetting and lubricating agent, 5 to 8 parts of filler, 0.1 to 1.0 parts of borax and 0.04% to 0.4% by weight of anti-discoloring and anti-fading agent based on the total weight of said mixture and small amounts of other conventional additives.

Claim 5

A process of manufacturing a composition of matter which is soft, pliable, non-sticky, non-toxic and rapid-drying and especially adapted for handicraft articles, said process including the steps of mixing together by weight 100 parts of non-toxic synthetic latex having no offensive or irritating smell and which does not cause chapped skin, 55 to 75 parts of at least one material selected from the group consisting of starch and grain flour which is mainly composed of starch, 35 to 55 parts bread crumbs having a porous structure composed of α-starch and thermally modified and solidified gluten, 1 to 2 parts astringent agent adapted to increase the gellation temperature of the starch, 3 to 6 parts wetting and lubricating agent, 5 to 8 parts filler, 0.1 to 1.0 parts of borax and 0.04% to 0.4% by weight of anti-discoloring and anti-fading agent based on the total weight of said mixture and small amounts of other conventional additives and continuing the blending of the mixture while regulating the temperature of the blended composition so that it rises up to about 50° C.

Claim 6

A process of manufacturing a composition of matter which is soft, pliable, non-sticky, non-toxic and rapid-drying and especially adapted for handicraft articles, said process including the steps of mixing together by weight 100 parts of non-toxic synthetic latex having no offensive or irritating smell and which does not cause chapped skin, 55 to 75 parts of at least one material selected from the group consisting of starch and grain flour which is mainly composed of starch, 35 to 55 parts bread crumbs having a porous structure composed of α-starch and thermally modified and solidified gluten, 1 to 2 parts astringent agent adapted to increase the gellation temperature of the starch, 3 to 6 parts wetting and lubricating agent, 5 to 8 parts filler, 0.1 to 1.0 parts of borax and 0.04% to 0.4% by weight of anti-discoloring and anti-fading agent based on the total weight of said mixture and small amounts of other conventional additives and continuing the blending of the mixture while regulating the temperature of the blended composition so that it rises up to about 50° C.

Claim 7

A composition according to claim 1 wherein said grain flour is wheat flour.

Claim 8

A composition according to claim 3 wherein said grain flour is wheat flour.

Claim 9

A process according to claim 4 wherein said grain flour is wheat flour.
