< First Examples >

Crayon only erasers include baking soda, starch, moisturizers, surfactants, alcohol and certain incense. In this embodiment, baking soda and starch are in the form of powder (powder) and the other components are in liquid form.

In the method of manufacturing the eraser for crayon only, baking soda and starch are first weighed, the moisturizing agent and the surfactant are thoroughly mixed, and then alcohol and a predetermined fragrance are added thereto. The mixture is thoroughly mixed using a mixing machine. Slowly pour into a crayon eraser.

The crayon exclusive eraser is provided with a crayon exclusive eraser in an amount of 20 to 50% by weight of baking soda, 5 to 50% by weight of starch, 10 to 30% by weight of a moisturizer, 5 to 20% by weight of a surfactant, 10 to 30% 1 to 5% by weight of fragrance is contained.

Baking soda is a synonym of Sodium Hydrogen Carbonate and is a colorless crystal. Monohydrogen sodium salt of carbonic acid. It is also called sodium bicarbonate, sodium acid carbonate, sodium bicarbonate, bicarbonate soda. The formula is NaHCO ₃ , a colorless crystalline powder with a specific gravity of 2.20. When heated, it generates carbon dioxide CO ₂ and water H _{2 O} and turns into sodium carbonate anhydride (anhydrous) Na ₂ CO ₃ . The aqueous solution of 2NaHCO ₃ → Na ₂ CO ₃ + H ₂ O + CO ₂ shows weak alkalinity due to hydrolysis, which discolors on methyl orange but neutral on phenolphthalein. When the aqueous solution is heated, it releases carbon dioxide gas at 65 ° C or higher and changes into a sodium carbonate solution. Even with the action of acids such as hydrochloric acid and sulfuric acid, carbon dioxide is generated.

The pure is filtered by filtration of carbon dioxide in a sodium carbonate solution and dried in a stream of carbon dioxide. It is industrially produced as an intermediate of the ammonia-soda method used in the production of sodium carbonate, and also occurs through carbon dioxide in sodium carbonate hydrate. Ammonium chloride, sodium chloride and the like are contained as an impurity. Therefore, if necessary, recrystallization is carried out from an aqueous solution of 65 DEG C or less.

It is used as medicines such as antacid, alkali, and side effect inhibitors when taking antacids, sulfates, etc., and is used as a raw material for producing sodium salts, a compounding agent for baking powder, powdered soap, a detergent such as fleece, a foam extinguishing agent, And carbon dioxide gas generators of beverages.

Baking soda has the property of swelling sideways, it acts to inflate bread, and is used for muffins, cakes, and steamed cakes.

It also contains a lot of ingredients that neutralize fatty acids and is useful when removing oil or dust that is not easily erased. In the present invention, the baking soda serves as an abrasive for removing the crease.

Starch refers to powders obtained through processes such as milling, bereavement, and separation using starch materials such as potato, sweet potato, and corn. In the present invention, corn starch is preferably used. Corn starch is a starch extracted from the endosperm of corn. When water is added to the cornstarch and heated, the starch becomes luxurious and viscous. The viscosity at this time is weaker than that of potato starch. But it has good stability and strong adhesion. The temperature required for the cornstarch to be luxurious is 87 ° C, which is higher than that of rice and potato starch. Transparency is lower than that of potato starch in a luxurious state. Corns are dent, flint, sweet corn, popcorn, and soft, though they are widely used and the color of the species is yellow. The corn has a general corn (about 27% of amylose content), waxy corn, and high amylose corn (more than 60% of amylose content). Corn starch is prepared according to the wet method.

In addition, corn starch is a water-soluble thickening agent that serves to increase the viscosity of cosmetics and is used in modeling packs to help impart adhesion.

In the present invention, corn starch can be used for gel form.

The moisturizing agent is to prevent the surface from drying. In one embodiment of the present invention, 1,2-hexanediol may be one kind of the moisturizing agent.

1,2-Hexanediol is widely used as a substitute for parabens and is widely used as a preservative for various cosmetics and extracts because of its excellent moisturizing and antibacterial properties. Since 1,2-hexanediol has little irritation compared with excellent antimicrobial activity, compatibility of water and alcohol It is excellent and universally usable in many product lines. Mainly used as a moisturizer, antibacterial agent, preservative or solvent.

Surfactants are added to maintain an emulsion state in which dispersed liquids such as water and oil can not be mixed. Surfactants, also called surfactants, are substances which are adsorbed on the surface of a liquid to increase the activity of the interface and significantly change the properties. Particularly, the surface tension is lowered and the cleaning power, dispersing power, emulsifying power, solubilizing power and disinfecting power are excellent and widely used in various industries including household detergents.

The surfactant is a compound that acts as a wetting, emulsifying, dispersing, solubilizing and cleaning agent by lowering the interfacial free energy of a gas, a liquid, and a solid. The surfactant is anionic, cationic, nonionic, And the system is divided into four types. In one embodiment of the present invention, there is no limitation on the kind of the surfactant.

In one embodiment of the present invention, Apple Wash may be used as the surfactant. Apple Wash is a natural surfactant that is made by acylating the essential amino acids obtained from apple juice. It is good in use feeling. It does not change the skin protein and does not affect defense system, so it is mainly used in shampoo or cosmetics.

Alcohol is a colorless transparent liquid, which in the present invention means ethyl alcohol.

Certain fragrances may be present as a flavor, odoriferous powder or liquid component. For example, banana incense powder and banana incense liquid are examples.
