Description

네일에나멜 조성물Nail Enamel Composition

본 발명은 네일에나멜 조성물에 관한 것으로서, 보다 구체적으로 폴리비닐부티랄과 에탄올을 주성분으로 하는 네일에나멜 조성물에 관한 것이다.The present invention relates to a nail enamel composition, and more particularly, to a nail enamel composition comprising polyvinyl butyral and ethanol as main components.

네일에나멜이란 일명 매니큐어라고 하는 것으로서, 종래 네일에나멜은 신경계통을 손상시키고 피부와 손톱의 각질에서 지방분과 유분을 유실시켜 손톱을 변형시키거나 피부를 거칠게 하는 등의 부작용을 유발하는 유독성 화학약품을 기재성분으로 하고 있는 바, 최근에는 이러한 문제점을 해소하기 위하여 인체에 안전하게 적용할 수 있는 성분들로 네일에나멜을 조성하고자 하는 시도가 있어 왔다.Nail enamel is a so-called manicure, and conventional nail enamel is a toxic chemical that causes side effects such as damage to the nervous system and loss of fat and oil from the keratin of skin and nails, resulting in deformation of the nails and rough skin. In order to solve this problem, in recent years, there have been attempts to form nail enamel with ingredients that can be safely applied to the human body.

그 대표적인 예로서, 니트로셀룰로오즈 락카를 사용한 네일에나멜 조성물이 잘 알려져 있다. 이러한 네일에나멜 조성물은 손톱에 대한 접착성을 향상시키기 위하여 천연수지, 아크릴수지, 변성 폴리에스테르 수지 및 설폰아미드 수지 등의 피막형성제를 배합하여 경도를 향상시키고 있으나, 이렇게 조성한 네일에나멜은 손톱 등에 도포한 후 제거하고자 하는 경우 아세톤이나 에틸아세테이트 등의 용제를 함유하는 제거제를 사용하여야 하였다.As a representative example thereof, nail enamel compositions using nitrocellulose lacquer are well known. The nail enamel composition improves hardness by blending film-forming agents such as natural resin, acrylic resin, modified polyester resin, and sulfonamide resin in order to improve adhesion to nails. If you want to remove after that, you should use a remover containing a solvent such as acetone or ethyl acetate.

그러나, 이와 같은 용제는 전술한 바와 같은 화학약품과 마찬가지로 손톱을 변형시키거나 피부를 거칠게 하는 등의 작용을 하는 유해 물질이라서 이러한 용제를 사용하여야 하는 네일에나멜 조성물은 아직 안심하고 사용할 수 있는 것이 아니었다.However, such a solvent is a harmful substance that acts to deform nails or rough skin like chemicals as described above, so the nail enamel composition which should use such a solvent has not yet been used with confidence.

따라서, 본 발명은 인체에 안전하게 적용할 수 있는 성분들로 조성되며 또한 제거시에도 인체에 순한 용제로 제거할 수 있어 소비자가 안심하고 사용할 수 있는 네일에나멜 조성물을 제공하는 것을 과제로 한다.Therefore, an object of the present invention is to provide a nail enamel composition which is composed of ingredients that can be safely applied to the human body and can be removed with a gentle solvent to the human body even when removed.

상기한 과제를 해결하기 위한 본 발명자의 연구에서 인체에 순한 것으로 알려진 폴리비닐부티랄과 에탄올을 기재성분으로 한 네일에나멜이 손톱에 대한 접착성이 우수하고 벗겨짐 저항성이 높으며, 이의 도포에 의해 형성된 피막은 인체에 순한 알코올에 의해 용이하게 용해, 제거할 수 있으므로 해서 소비자가 안심하고 사용할 수 있게 된다는 사실을 알게 되었다.Nail enamel based on polyvinyl butyral and ethanol, which is known to be gentle to the human body in the study of the present inventors for solving the above problems, has excellent adhesion to nails and high peeling resistance, and is formed by coating thereof. Since it can be easily dissolved and removed by the mild alcohol in the human body, it has been found that consumers can use it with confidence.

그러므로, 본 발명에 의하면 안료, 가소제, 침강방지제 및 안료와 같은 통상의 네일에나멜용 미량성분과 기재성분으로 되는 네일에나멜 조성물에 있어서, 상기 기재성분이 에탄올 용해성 폴리비닐부티랄 수지 20~30중량%와 에탄올 70~80중량%로 이루어진 것을 특징으로 하는 네일에나멜 조성물이 제공된다.Therefore, according to the present invention, in a nail enamel composition comprising a trace component for a conventional nail enamel and a base component such as a pigment, a plasticizer, an antisettling agent and a pigment, the base component is 20 to 30% by weight of ethanol-soluble polyvinyl butyral resin. And it provides a nail enamel composition comprising 70 to 80% by weight of ethanol.

본 조성물에 있어서, 폴리비닐부티랄 수지는 폴리비닐아세탈 수지의 일종으로서 인체에 비교적 안전하게 적용할 수 있으며, 기재성분중 폴리비닐부티랄 수지의 함량은 20~30중량%가 적합하다. 만일 폴리비닐부티랄 수지의 함량이 20중량% 미만인 경우에는 점도가 낮아져서 도막의 평활성을 잃게 되며 광택을 유지하지 못하고 부착성이 떨어지게 되며, 30중량% 초과시에는 건조속도가 느리고 굴곡안정성이 불량하게 된다. 이와 반대로 기재성분중 에탄올의 함량이 80중량% 초과시에는 점도가 낮아져서 도막의 평활성을 잃게 되며 광택을 유지하지 못하고 부착성이 떨어지게 되며, 70중량% 미만의 경우에는 건조속도가 느리고 굴곡안정성이 불량하게 된다.In the present composition, the polyvinyl butyral resin is a kind of polyvinyl acetal resin and can be applied relatively safely to the human body. The content of the polyvinyl butyral resin in the base component is preferably 20 to 30% by weight. If the content of the polyvinyl butyral resin is less than 20% by weight, the viscosity is lowered, so that the coating film loses its smoothness, the glossiness cannot be maintained, and adhesiveness is lowered, and when it exceeds 30% by weight, the drying speed is slow and the flexural stability is poor. . On the contrary, when the content of ethanol in the base component exceeds 80% by weight, the viscosity is lowered, so that the coating film loses its smoothness, the glossiness cannot be maintained, and the adhesion is lowered.When the content is less than 70% by weight, the drying speed is slow and the bending stability is poor. do.

위에 언급한 바와 같은 본 발명의 특징 및 기타의 장점은 후술되는 실시예의 기재로부터 보다 명백하게 될 것이다.Features and other advantages of the present invention as mentioned above will become more apparent from the description of the embodiments described below.

하기 실시예에서 사용한 폴리비닐부티랄 수지는 폴리비닐아세탈 76%, 폴리비닐아세테이트 3%, 폴리비닐알코올 21%로 이루어진 것이었다.The polyvinyl butyral resin used in the following examples consisted of 76% polyvinyl acetal, 3% polyvinylacetate, and 21% polyvinyl alcohol.

평가시험Evaluation test

상기한 실시예 1~4 및 비교예 1~4의 네일에나멜에 대하여 다음과 같은 평가시험을 하였다. 평가결과는 하기 표 1에 제시된다.The following evaluation test was done about the nail enamel of the said Examples 1-4 and Comparative Examples 1-4. The evaluation results are shown in Table 1 below.

* 건조성 : 손톱에 시료를 25℃, 습도 50~60% 조건하에서 브러쉬로 도포한 후, 2~4분 이내에 도막에 자국이 마국이 마르지 않고, 5~8분 이내에 도막을 눌러도 자국이 나지 않는 가를 평가.* Dryness: After applying the sample to the nails with a brush at 25 ℃ and humidity of 50 ~ 60%, the marks do not dry on the coating within 2 ~ 4 minutes, and the marks do not appear even after pressing the coating within 5 ~ 8 minutes. Rate it.

* 광택성 : 시료를 25㎛ 유리판에 필림어플리케이터로 코팅하고 24시간 실온에서 건조한 후 코팅필름의 광택을 광택계에 의해 60°의 경사각, 60°의 반사각에서 측정하여 평가.* Glossiness: The sample was coated on a 25 μm glass plate with a film applicator and dried at room temperature for 24 hours, and then the gloss of the coated film was measured at a 60 ° inclination angle and 60 ° reflection angle by a glossmeter.

* 도막박리성 : 손톱에 시료를 25℃, 습도 50~60% 조건하에서 브러쉬로 도포한 후, 8분이상 경과후 도막이 문지름에 의해 벗겨지지 않는 가를 평가.* Peelability of the film: After the sample is applied to the nail with a brush at 25 ° C and humidity of 50 ~ 60%, it is evaluated whether the coating film does not come off by rubbing after more than 8 minutes.

* 굴곡성(유연성) : 시료를 25㎛ PVC 판에 균일하게 도포하고 실온에서 48시간 건조한 다음 꺾임굴곡을 측정하여 평가.* Flexibility (flexibility): The sample was uniformly coated on a 25 μm PVC plate, dried at room temperature for 48 hours, and evaluated by measuring the bending bend.

* 도막강도 : 시료를 25㎛ 철판에 코팅하고 실온 25℃에서 24시간 건조한 후 코팅된 필름의 강도를 연필강도 시험기로 측정하여 평가.* Coating film strength: After coating the sample on a 25㎛ iron plate and dried for 24 hours at room temperature 25 ℃ by measuring the strength of the coated film by a pencil strength tester.

* 냄새 : 냄새가 역하고 불쾌한 지, 그리고 신경계를 자극하는 지를 평가.* Odor: Evaluate if the smell is reverse and unpleasant and irritates the nervous system.

* 에탄올 용해성 : 시료조성물을 0.35㎛로 필름어플리케이팅하고 실온에서 48시간 방치한 후 25g의 하중하에서 비커(vicker) 강도계를 측정하여 평가.* Ethanol solubility: The sample composition was film-applied at 0.35 μm and left for 48 hours at room temperature, and then measured by measuring a beaker (vicker) strength meter under a load of 25 g.

[표 1]TABLE 1

상기 표 1로부터, 네일에나멜의 건조성, 광택성, 도막강도, 유연성, 및 박리성은 실시예와 비교예가 비슷하지만, 비교예의 네일에나멜은 냄새가 역하고, 에탄올에 대한 용해성이 없는 반면에 본 발명에 따르는 실시예의 네일에나멜은 냄새가 역하지 않고 에탄올에 용해가 잘되는 것을 알 수 있다.From Table 1, although the dryness, glossiness, coating strength, flexibility, and peelability of the nail enamel are similar to those of the examples, the nail enamel of the comparative example has an odor and has no solubility in ethanol. Nail enamel of the embodiment according to the odor is not reversed, it can be seen that well dissolved in ethanol.

즉, 본 발명에 따르는 네일에나멜 조성물은 인체에 비교적 안전하게 적용할 수 있으며, 또한 그 도포후 제거시에 인체에 순한 용제인 에탄올에 의해 용이하게 용해, 제거될 수 있으므로 손톱을 변형시키거나 피부를 거칠게 하는 등의 부작용을 방지하는 효과가 있는 것이다.That is, the nail enamel composition according to the present invention can be applied relatively safely to the human body, and can be easily dissolved and removed by ethanol which is a gentle solvent to the human body upon removal after application thereof, thereby deforming nails or roughening the skin. It is effective to prevent such side effects.
