Description

손톱 코팅제 {NAIL COATINGS}Nail coating agent {NAIL COATINGS}

본 발명은 손톱 코팅제에 관한 것으로서, 양호한 산소투과도를 갖는 UV 경화성 미용 손톱 코팅제에 관한 것이다. The present invention relates to a nail coating agent, and relates to a UV curable cosmetic nail coating agent having good oxygen permeability.

미용 산업 분야를 중심으로 손톱 코팅제가 널리 사용된다. 손톱 코팅제는 패션에 관심이 많은 사용자가 손톱에 장식 효과를 부여하거나, 깨지기 쉬운 손톱 표면을 강화시키기 위한 목적으로 주로 사용된다. Nail coatings are widely used in the beauty industry. The nail coating agent is mainly used for the purpose of giving a decorative effect to a nail or strengthening a fragile nail surface by a user who is interested in fashion.

최근에는 UV 경화성 미용 손톱 코팅제의 사용이 증가하고 있다. UV 경화성 미용 손톱 코팅제는 코팅제를 손톱에 칠한 후 자외선 램프(UV 램프)를 조사하여 경화하는 방식으로 손톱 표면에 코팅한다. Recently, the use of UV curable cosmetic nail coatings is increasing. The UV curable cosmetic nail coating agent is coated on the nail surface by applying a coating agent to the nail and curing it by irradiating with an ultraviolet lamp (UV lamp).

상용제품으로 널리 사용되는 UV 경화성 미용 손톱 코팅제는 젤 성분을 주 성분으로 포함하며, 이러한 젤 성분은 소프트 젤(Soft Gel)과 하드 젤(Hard Gel)로 구분된다. UV curable cosmetic nail coatings, which are widely used as commercial products, contain gel components as a main component, and these gel components are divided into soft gels and hard gels.

하드젤은 아크릴을 주성분으로 하고 분자량이 작은 올리고머를 주로 사용한다. 소프트 젤은 일반적으로 젤 폴리시(Gel Pilosh)라고 불리우며 분자량이 큰 우레탄아크릴 계통의 올리고머를 주성분으로 한다. Hard gel mainly uses acrylic and oligomers with small molecular weight are mainly used. The soft gel is generally called gel polish, and has a large molecular weight urethane acrylic oligomer as its main component.

하드젤은 UV 경화 후에 분자 구조가 타이트(Tight)한 코팅이 형성되는데, 이러한 타이트한 구조로 인하여 아세톤 등을 이용하여 도막 제거 시 아세톤이 분자 내에 침투하지 못하기 때문에 제거가 용이하지 않다는 단점이 있다. The hard gel has a molecular structure tight coating after UV curing, and due to this tight structure, acetone does not penetrate into the molecule when removing a coating film using acetone, etc., and thus has a disadvantage that it is not easy to remove.

이와 대비하여, 소프트 젤은 하드젤과 유사하게 광택이 나는 특성과 우수한 내구성을 가지면서도, UV 경화 후에 분자 구조가 소프트(Soft)하게 형성이 되어 도막 제거 시 아세톤, 알콜 등을 침투시켜 제거가 용이하다는 장점이 있다. In contrast, the soft gel has a shiny property and excellent durability similar to that of a hard gel, and the molecular structure is formed soft after UV curing, so it can be easily removed by penetrating acetone, alcohol, etc. when removing the coating film. It has the advantage of being.

그러나, 소프트 젤은 우레탄아크릴의 분자 구조상 산소투과율이 낮기 때문에 장기간 시술하게 되면 자연 상태의 건강한 손톱을 유지하기가 어렵게 된다는 한계를 갖고 있었다. However, the soft gel has a limitation in that it is difficult to maintain healthy nails in a natural state when the procedure is performed for a long time because the oxygen permeability is low due to the molecular structure of urethane acrylic.
