Description

[Technical Field]

[0001] This invention relates to an ink cosmetic composition, particularly an ink cosmetic for application to keratinous materials. The invention also relates to a method of using the composition in printing on keratinous materials. [Background technology]

[0002] Traditional tattoos involve injecting pigment into the dermis layer of the skin. While the initial treatment cost is high, once applied, they are permanent and difficult to remove.

[0003] Recently, following traditional tattooing techniques, henna tattoos (a method of drawing on the body using ink), water transfer stickers (a form of body painting that uses water to adhere transfer paper to the body), and other body painting methods that use ink in various ways, such as stamping patterns, have been proposed.

[0004] Among temporary body painting methods, methods for printing onto the skin using two-component skin printing inks are reported in KR101655978 B1 and KR20180057953 A. The two-component skin printing inks in these methods include an ink composition and an ink immobilizer or fixative composition as a primer for the ink composition.

[0005] Furthermore, WO 2023 / 229315 discloses a tattoo printing method in which a powder-containing ink fixative composition for tattoo printing may be applied before or after the ink composition for tattoo printing is applied. This document also discloses that a balm-type fixative composition may be applied after the ink composition for tattoos has been applied.

[0006] When an ink composition is typically applied to a keratinous substance by an inkjet method, the ink composition needs to be ejected from the nozzle of the ink cartridge. Therefore, it is preferable that the ink composition does not cause problems with clogging the ink cartridge nozzle. Furthermore, since the ink composition may be stored in the ink cartridge for a long period of time, it is required that the ink composition has improved stability and storage characteristics.

[0007] Furthermore, the formulations of environmentally friendly cosmetics are designed and developed with environmental issues in mind, and this is an important goal in addressing global challenges. Therefore, it is essential to propose more sustainable compositions, preparation methods, and ingredients to address these environmental concerns.

[0008] In this context, it is particularly important to develop novel compositions, such as novel ink compositions for keratinous materials, that have a better carbon footprint by promoting the use of renewable raw materials and / or materials with a good index of naturalness and / or materials of natural origin.

[0165] The application of the composition, primer composition, and / or coating composition according to the present invention in steps (i) to (iii) can be carried out by any means, such as an inkjet method, a spray method, a drop method, or by bringing the ink composition into contact with the keratin substance using a finger, gauze, cotton, stick, tip, or applicator. Preferably, the composition according to the present invention can be applied by an inkjet method or a spray method.

[0166] In a preferred embodiment of the present invention, the composition according to the present invention can be applied in a single operation, preferably by using a multipart composition or kit according to the present invention, particularly by using a printing device, such as Prinker's Prinker M skin transfer printer.

[0167] Each of the compositions may be dried after application to form a primer layer, an ink layer, and / or a coating layer. Therefore, the method according to the present invention may include one or more drying steps between step (i) and (ii), i.e., before step (ii), between step (ii) and (iii), i.e., after step (ii), and / or after step (iii), i.e., after step (iii), if step (i) is present. In a preferred embodiment of the present invention, the method includes steps (i) and (iii), and includes drying steps between steps (i) and (ii), between steps (ii) and (iii), and after step (iii).

[0168] The drying process can be carried out under ambient conditions for 1 to 120 seconds, preferably for 30 to 60 seconds. The drying process may be carried out by heating the applied composition, or simply by keeping the applied composition under ambient conditions. Ambient conditions, here, refer to a temperature in the range of 10°C to 40°C, particularly 15°C to 30°C, and atmospheric pressure (10°C). 5 It may indicate Pa.

[0169] In the method according to the present invention, since the composition according to the present invention is used as an ink composition, it is possible to efficiently produce ink printed on keratinous material, preferably skin, hair, eyebrows and / or eyelashes, such as temporary tattoos. [Examples]

[0170] The present invention will be described in more detail by reference to examples. However, these examples should not be construed as limiting the scope of the present invention. The following examples are presented as non-limiting illustrations in the art of the present invention.

[0171] [Composition] Each of the compositions from Examples 1-4 (Ex.1-Ex.4) and Comparative Examples 1-7 (Comp.Ex.1-Comp.Ex.7) was prepared by mixing the components listed in Tables 1 and 2 below. All numerical values ​​regarding the amount of components are based on "mass%" as active raw materials.

[0172] [evaluation] (pH stability) The pH of each composition was measured immediately after preparation (T0) and then after storage at 45°C for 2 months (T2M) using a pH meter (LAQUA pH meter F-72L by HORIBA) at 25°C. The following criteria were used for evaluation. Excellent: After storage, the pH value changed by 0-0.3. Excellent: After storage, the pH value changed by more than 0.3 to 0.5. Good: After storage, the pH value changed by more than 0.5 to 1.0. Normal: After storage, the pH value changed by more than 1.0 to 1.5. Defect: After storage, the pH value changed to above 1.5.

[0173] (Storability) The shelf life of each composition was evaluated by determining its antimicrobial protective properties according to ISO standard 11930. The evaluation was performed according to the following criteria. OK: Bacteriological risk is considered acceptable. This indicates that the composition is protected against the growth of microorganisms that could pose a potential risk to the user. NG: The bacteriological risk is considered unacceptable.

[0174] (Nozzle clogging resistance) Nozzle clogging resistance was evaluated by the following printing test. First, ink cartridges containing each of the compositions were stored at 37°C for two weeks. Next, the ink cartridges were set in a printing device (Prinker M, manufactured by Prinker Corporation) and the ink was printed on paper. One minute after printing, the nozzle clogging characteristics were determined according to the following criteria. Excellent: No blurry print patterns were observed. Very good: 1-5% of blurry print patterns were observed. Good: Over 5% to 10% of the print pattern was blurry. Normal: Over 10% to 20% of the print patterns were blurred. Defect: Over 20% of the print patterns were found to be blurry.

[0175] The results are shown in Table 1 and Table 2.

[0176] [Table 1]

[0177] [Table 2]

[0178] As shown in Table 1 and Table 2, the compositions according to the present invention, including combinations of components (a) to (c), exhibited good stability and shelf life, and showed improved resistance to nozzle clogging.

[0179] On the other hand, the composition according to Comparative Example 1, which did not contain preservatives or buffering agents, failed to exhibit acceptable pH stability and shelf life. Furthermore, the composition according to Comparative Example 2, which did not contain preservatives, did not exhibit acceptable shelf life. Furthermore, the composition according to Comparative Example 3, which did not contain buffering agents, failed to exhibit good pH stability. Furthermore, the composition according to Comparative Example 4, which did not contain any of components (a) to (c), failed to exhibit good pH stability, nozzle clogging resistance, and shelf life. Furthermore, the composition according to Comparative Example 5, which did not contain water-soluble acid dyes or buffering agents, failed to exhibit good pH stability and nozzle clogging resistance. Furthermore, the composition according to Comparative Example 6, which did not contain water-soluble acid dyes or preservatives, failed to exhibit good nozzle clogging resistance and shelf life. Furthermore, the composition according to Comparative Example 7, which contained pigments, failed to exhibit good nozzle clogging resistance.

[0180] Therefore, it can be concluded that the composition according to the present invention is very suitable as an ink composition for printing inks for keratin materials, and in particular very suitable for temporary tattoos.
