Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an ink composition for directly marking the skin of the human body, and more particularly relates to an additional patent to Patent Application No. 45189 filed in 1972.

The routes by which chemical substances are absorbed into the human body are divided into respiratory, cutaneous, and digestive routes. And when harmful substances come into contact with the skin,
It dissolves into the body through sweat glands, sebaceous glands, hair follicles, etc., enters the bloodstream through capillaries, and circulates throughout the body, causing damage. In particular, if the skin has trauma or eczema, absorption will be accelerated.

Therefore, skin mark inks must be composed of less toxic substances.

Furthermore, when the marked area is wiped with a disinfectant, the mark must remain clearly.

In view of the above circumstances, and with the aim of eliminating these various drawbacks, the present invention has been made to contain one or more types of less toxic basic dyes, especially triphenylmethane basic dyes, and to use a solvent as a solvent. Using ethyl alcohol, inpropyl alcohol, n-propyl alcohol, water, etc., and adding glycerin, propylene glycol, polyoxy-7ethylene or its derivatives, polyoxypropylene or its O derivatives, etc. as a drying and viscosity regulator,
In addition, the present invention provides an ink composition for skin marks containing an appropriate amount of tannic acid as an anti-suppuration agent, a blood agent, or a fixing agent for basic dyes, and is suitable for marking during surgical operations or in markets and supermarkets. It is ideal for direct marking on the surface of fruits, vegetables, etc.

The present invention will be explained in detail below. In addition, "Example Middle" indicates parts by weight.

Ethyl alcohol and inglobil alcohol, which are used as partial solvents, are generally used as sterilizing agents, and normal propyl alcohol is used in cosmetics or dental lotions. As shown in the above embodiments, the rate of solvent volatilization after marking varies depending on the blending ratio of alcohol and water, and therefore the drying rate of the ink can be adjusted freely. Further, the adjusting agent plays the role of adjusting the drying speed and viscosity of the ink to prevent the ink from drying out excessively and to fix the pigment after marking to the skin. Both glycerin and propylene glycol used as regulators have very low toxicity. In addition, polyoxyethylene and polyquine propylene are generally used as base materials such as soft powder, suppositories,
It is used in creams, lotions, etc. and has low toxicity, and examples of derivatives thereof include various polyoxyethylene ethers derived from higher alcohols of C1myClg and alkylphenols of 08 to C9.

However, when using only the above-mentioned conditioner, the adhesion strength of the pigment to the skin etc. is not necessarily firm and firm, and there is a risk that it will come off due to friction or weak wiping with a damp cloth. There is.

Therefore, by adding tannic acid as an auxiliary regulator to the above various inks, the ink can be more reliably adhered to the skin and the like. Note that sodium benzoate is used as a preservative.

Compositions based on these formulations are particularly characterized in that they leave clear marks even when wiped with a disinfectant. There are two types of marking: one is done before applying the disinfectant (one or two types), and the other is after the disinfectant is applied, but in the latter case, there is a risk that the mark will fade when wiped with the disinfectant. However, in the present invention, an ink that does not disappear easily can be obtained by allowing tannic acid to act on a basic dye, particularly a triphenylmethane basic dye.

Also, green ink is particularly effective for black skin marks.

Depending on the patient, it may be necessary to mark damaged skin, and the same pen cannot be used on other people because bacteria may adhere to and remain on the marking pen tip. In order to solve this problem, the following skin mark ink composition is applied.

Pigment (each color) 3-10 parts Ethyl alcohol 100 parts Additive propylene glycol 40 Tannic acid

1. The ink composition of the present application uses a basic dye with low toxicity, especially a triphenylmethane basic dye, as a coloring agent, and after the solvent such as alcohol and water has evaporated, the dye is replaced with glycerin and propylene. Conditioners such as glycol and tannic acid make it more securely adhere to the skin, and the handwriting does not come off easily due to friction, so when erasing it, it can be washed with water or wiped with a wet cloth. You can definitely erase it by doing this.

Therefore, it is ideal for marking incisions during surgical operations, body pendenting, and direct marking of foods such as fruits and vegetables, and is highly safe as each composition has low toxicity. It is a relatively safe ink even if the ink accidentally gets into the mouth of an infant or the like.

As mentioned above, the ink composition according to the present invention is novel and has significant practical effects.

4. The additional related original patent invention is an ink composition for skin marks in which ethyl alcohol or the like is used as a solvent, glycerin or the like is used as a modifier, and low toxicity food coloring is added. This ink composition for skin marks uses a basic dye with low toxicity as a pigment and further contains an appropriate amount of tannic acid.

In other words, the claimed invention is an invention in which all or a major part of the matters essential to the structure of the original patented invention is used as all or a major part of the matters essential to the structure, and the claimed invention has the same purpose as the original patented invention. It is something to be achieved.
