  The Falkata material used in the present invention is wood that is generally cultivated in Southeast Asia, but belongs to the Nemnophyllum genus Falkata, and the common name varies depending on the production area. According to a technical book, `` Sengon laut is also referred to as Alibizia falcata Back, Moluccan sau in Philippine, Bantai in Malaya Sarawak and Brunei Saba, Indonesia. In Sengon laut, in Papua New Guinea it is called Albizia, and in Taiwan it is called Singon (Singon). Trees of the genus Aliizzia are distributed from tropical Africa to Asia, and it is said that its number is 130. The mackerel is divided into two groups according to the size of the specific gravity: the mackerel has an air-dry specific gravity of 0.48 as a boundary, and the low one is distinguished from Batai and the high one is distinguished from Batai batu. Falcata is considered to be a typical tree species of the former, A. chinensis, A. pedicellata in the former, and A. lebbekoides, A. retusa, A. saponaria in the latter. ("Tropical useful tree species" published by the Ministry of Agriculture and Forestry, Tropical Agriculture Center and Tropical Forestry Association), there are many types of Falkata wood, and these trees have the function of removing residual chlorine. .

  The growth of these Falkata timbers is very fast, with a height of 35m in 10 years and a record of 44m in 17th grade. Besides being used for wooden shoes, it is effectively used overseas as a substitute for plywood, veneer and paulownia wood, as a material for pulp, and recently as an environmental bento box.

  In order to use these Falkata materials as a residual chlorine removal material, first, a strip cut into a predetermined length is sliced parallel to the axial direction to obtain a strip, and then the strip is cut into a fixed shape. It is preferable to mainly use a thin plate and a chip having a size of 20 mm square or less and a thickness of 1.5 mm or less.

  In addition, the above wood and chips are further pulverized, and the pulverized material with a size of about several millimeters is put in a non-woven cloth storage bag, placed in a cold water pot or kettle, and the tap water inside the kettle is boiled. Residual chlorine may be removed.

  Alternatively, an extract obtained by using a chip material of Falkata as a raw material and boiling the raw material in hot water is used directly as an extract for removing residual chlorine, or an edible powder having solubility in the extract It can also be used alone as a granular residual chlorine removing agent obtained by mixing the body, or as a residual chlorine removing agent which is further blended with an approximately the same amount of a foaming agent into small granules.

  In addition to the above-mentioned Falkata wood, domestic timbers such as persimmon, paulownia, cedar, persimmon, beech, zelkova, oak, cherry, fir, honoki, linden, redwood, wig, walnut, duck, maple, dogwood, chestnut, karin, teak, The same effect can be obtained by using wood chips selected from Agatis, Enju, Tochu, Olive, Lawan, Pine, Bamboo, Apple, Hickory, Walnut, White Oak, Nem Tree, or hot water extract from the chip. Obtainable.

  Similarly, hydrolyzed collagen powder (hereinafter referred to as collagen powder) composed of animal collagen powder obtained from pigs, cattle, etc., marine collagen obtained from fish, etc. Silk protein silk (fibroin) hydrolyzed powder (hereinafter referred to as silk powder) hydrolyzed in the presence of silk protein silk (hereinafter referred to as silk powder) Sericin) hydrolyzed powder (hereinafter referred to as sericin powder) and powder made of chitosan powder (hereinafter referred to as chitosan powder) obtained by deacetylating chitin obtained by alkali treatment of shellfish and shrimp shells. Used to remove residual chlorine as well.

  The collagen powder, silk powder, and sericin powder are generally protein hydrolyzed powders, and proteins are usually made from 20 types of amino acids. In addition to the 10 non-essential amino acids synthesized in the human body, this amino acid cannot be made in the body in addition to the two semi-essential amino acids that are slow to synthesize in the body and essential for infants. It is said that there are eight essential amino acids that will cause some illness if not supplied as a meal.

  In the present invention, it has been found that the protein hydrolyzed powder composed of the above collagen powder, silk powder, sericin powder and its aqueous solution have a residual chlorine removing action. Naturally, the amino acids constituting these proteins also have a residual chlorine removing action. Specifically, residual chlorine can be removed even with commercially available sodium glutamate and bonito.

  Furthermore, plants such as raw wormwood and tutaba leaves, seaweeds such as kelp, vegetables such as fresh cabbage, dried cabbage and fresh cucumber, teas such as dried green tea, grains such as refined white rice, seasonings such as salt Residual chlorine in tap water can also be removed by using fruits such as citrus fruits, apples, strawberries, pears and peaches, and flower buds such as roses.

  As the removal material of the present invention, not only the above-mentioned wood-based extract, but also extracts extracted from collagen powder and the like, and extracts obtained from dried products such as plants, vegetables, and grains, or dried extracts are extracted. In addition to being able to be used as a remover, it can be mixed with powders obtained by mixing with edible powders and edible powders, or mixed with auxiliary materials such as fragrances, colorants, solvents, stabilizers and antioxidants, or It can be mixed with excipients such as starch and lactose and used as a solid remover for tablets and the like.

  Moreover, the removing agent of the present invention can be used not only for removing residual chlorine in tap water but also as a medicine or a quasi-drug as a bathing agent having a warm bath effect. It can be used in the same manner as commercially available products such as powders, tablets, granules, and bath oils.
