본 발명은 레시틴, PG계 계면활성제, 소르비탄계 계면활성제 및 점증제를 유효성분으로 함유하여, 안정도가 개선된 유중수형 화장료 조성물에 관한 것이다.The present invention relates to a water-in-oil cosmetic composition with improved stability by containing lecithin, a PG-based surfactant, a sorbitan-based surfactant, and a thickener as active ingredients.
Description
본 발명은 레시틴, 계면활성제 및 점증제를 유효성분으로 함유하여, 안정도가 개선된 유중수형 화장료 조성물에 관한 것이다. 보다 상세하게는, 유중수형 제형 형성에 있어서 PEG계 계면활성제를 사용하지 않고, PG계 계면활성제 및 소르비탄계 계면활성제를 사용하면서, 레시틴을 유화 안정화제로서 함유하는 유중수형 화장료 조성물에 관한 것이다.The present invention relates to a water-in-oil type cosmetic composition with improved stability by containing lecithin, a surfactant, and a thickener as active ingredients. More specifically, it relates to a water-in-oil cosmetic composition containing lecithin as an emulsion stabilizer while using a PG-based surfactant and a sorbitan-based surfactant instead of using a PEG-based surfactant in forming a water-in-oil formulation.
유중수형(W/O) 제형에서는 외상의 오일 점증이 어려워 제형의 점도 및 경도가 경시적으로 하락하고 제형의 분리가 이루어지기 쉬운 경향이 있다.In water-in-oil (W/O) formulations, it is difficult to thicken the external oil, so the viscosity and hardness of the formulation decreases over time, and separation of the formulation tends to occur.
일반적으로 수중유형(O/W)의 유화 안정화 메커니즘은 크게 다음 두 가지 과정을 거친다. 1) 유화 입자 안정화: 계면활성제, 고급 알코올, 산(acid)으로 유화막을 견고하게 하여 콜로이드 입자의 합체(coalescence)를 막는다. 2) 형성된 유화입자 안정화: 외상 물 파트의 점증을 통하여 유화 입자의 크리밍(creaming)과 응집(flocculation)을 막는다.In general, the oil-in-water (O/W) emulsion stabilization mechanism largely goes through the following two processes. 1) Stabilization of emulsion particles: Strengthens the emulsion film with surfactants, higher alcohols, and acids to prevent coalescence of colloidal particles. 2) Stabilization of formed emulsified particles: Prevents creaming and flocculation of emulsified particles through thickening of external water part.
[O/W 화장료 제형의 유화 안정화 메커니즘][Emulsion stabilization mechanism of O/W cosmetic formulation]
그러나, 유중수형 제형에서는 외상의 오일을 점증하는 것이 어려우므로, 위와 같은 원리 중 입자들 간의 합체와 응집을 막는 것이 어렵게 된다. 그에 따라, 제형의 점도 및 경도가 경시적으로 하락하고 결국 제형이 분리된다. 특히 점도가 낮은 제형에서 이러한 현상이 가속화될 수 있다.However, in a water-in-oil type formulation, it is difficult to gradually increase the oil in the outer layer, making it difficult to prevent coalescence and agglomeration between particles among the above principles. Accordingly, the viscosity and hardness of the formulation decrease over time and eventually the formulation separates. This phenomenon can be accelerated, especially in low viscosity formulations.
또한, 유중수형 제형 형성 시, PEG(polyethylene glycol) 계열의 계면활성제가 다른 유중수형용 계면활성제에 비해 약하기는 하지만 안정적인 계면막을 형성할 수 있으며 다양한 구간의 HLB 값을 가진 원료가 화장품용으로 사용할 수 있도록 상용화가 되어 있는 등 여러 가지 편의를 고려하여, 다소 불안정함에도 불구하고 당업계에서 널리 사용되어 왔다. 그러나, 최근 안전성에 대한 소비자의 관심 증가로 PEG계 계면활성제의 사용이 점차 감소하는 추세이며, 그에 따라 유중수형 제형의 안정도를 확보하는 것이 더욱 어려운 일이 되었다. 따라서, PEG계 계면활성제를 사용하지 않으면서도 제형 안정도가 개선된 유중수형 화장료 개발에 대한 필요성이 제기되고 있다.In addition, when forming a water-in-oil formulation, although PEG (polyethylene glycol)-based surfactants are weaker than other water-in-oil type surfactants, they can form a stable interfacial film, and raw materials with HLB values in various ranges can be used for cosmetics. In consideration of various conveniences, such as commercialization, it has been widely used in the industry despite being somewhat unstable. However, due to the recent increase in consumer interest in safety, the use of PEG-based surfactants is gradually decreasing, and as a result, securing the stability of water-in-oil formulations has become more difficult. Therefore, there is a need to develop water-in-oil cosmetics with improved formulation stability without using PEG-based surfactants.
본 발명은 상기와 같은 문제점을 해결하기 위하여, PEG계 계면활성제를 사용하지 않으면서도 제형 안정도가 개선된 유중수형 화장료 조성물을 제공하는 것을 목적으로 한다.In order to solve the above problems, the purpose of the present invention is to provide a water-in-oil cosmetic composition with improved formulation stability without using a PEG-based surfactant.
본 발명자들은 놀랍게도, PEG계 계면활성제 대신 PG(polyglyceryl)계 계면활성제 및 소르비탄(sorbitan)계 계면활성제를 사용하면서, 이와 함께 레시틴(lecithin)을 유중수형 제형에 적용하면 점도 및 경도가 향상되어 안정도가 개선되는 것을 발견하고 본 발명을 완성하였다.Surprisingly, the present inventors found that when PG (polyglyceryl)-based surfactant and sorbitan-based surfactant were used instead of PEG-based surfactant and lecithin was applied to the water-in-oil formulation, the viscosity and hardness were improved and stability was improved. was found to be improved and the present invention was completed.
따라서, 상기한 목적을 달성하기 위하여, 본 발명은 레시틴, PG계 계면활성제, 소르비탄계 계면활성제 및 점증제를 유효성분으로 함유하는 안정도가 개선된 유중수형 화장료 조성물을 제공한다.Therefore, in order to achieve the above object, the present invention provides a water-in-oil type cosmetic composition with improved stability containing lecithin, a PG-based surfactant, a sorbitan-based surfactant, and a thickener as active ingredients.
본 발명은 레시틴을 유중수형 조성물의 유화 안정화제로 사용함으로써, 오일 층의 분리를 억제하고 점도 및 경도를 상승시켜 안정도가 향상된 유중수형 화장료 조성물을 제공할 수 있다. 또한, 장기간 보관 시 및 고온/저온의 가혹한 조건에서도 분리되지 않고 경시적 안정성을 유지하는 유중수형 화장료 조성물을 제공할 수 있다. 또한, PEG계 계면활성제를 포함하지 않아 피부 안전성이 높으면서도 사용감을 개선시킨 유중수형 화장료 조성물을 제공할 수 있다.The present invention can provide a water-in-oil cosmetic composition with improved stability by suppressing separation of the oil layer and increasing viscosity and hardness by using lecithin as an emulsion stabilizer for the water-in-oil composition. In addition, it is possible to provide a water-in-oil type cosmetic composition that maintains temporal stability without separation even when stored for a long period of time and under harsh conditions of high and low temperatures. In addition, it is possible to provide a water-in-oil type cosmetic composition that does not contain a PEG-based surfactant and has high skin safety while improving the feeling of use.
도 1은 본 발명의 실시예 1~2와 비교예 1~7의 상온 방치 시(48시간 경과) 제형 변화를 비교한 사진이다.Figure 1 is a photograph comparing the change in formulation of Examples 1 to 2 of the present invention and Comparative Examples 1 to 7 when left at room temperature (after 48 hours).
유중수형 제형 형성 시, PEG계 계면활성제를 대신하여 사용하고자 할 때 만족할 만한 안정도를 나타내는 계면활성제를 찾기는 쉽지 않다. PG계 계면활성제는 PG계 계면활성제 단독으로는 유중수형 제형의 안정도를 충분히 확보하기 어렵다. 또한, 레시틴은 유화력이 약하여 수중유형 제형의 보조 성분으로 사용되어 왔다.When forming a water-in-oil formulation, it is not easy to find a surfactant that exhibits satisfactory stability when trying to use it instead of a PEG-based surfactant. It is difficult to sufficiently secure the stability of a water-in-oil type formulation with PG-based surfactants alone. In addition, lecithin has weak emulsifying power and has been used as an auxiliary ingredient in oil-in-water formulations.
그런데, 놀랍게도 PG계 계면활성제와 레시틴을 조합하여 유중수형 제형에 적용하면, 점도 및 경도가 향상되어 안정도가 개선되는 것을 본 발명자들은 발견하였다. 또한, PEG계 계면활성제를 대체하는 계면활성제로서, PG계 계면활성제와 소르비탄계 계면활성제를 병용하면 안정도가 더욱 향상되는 것을 발견하고 본 발명을 완성하였다.However, surprisingly, the present inventors discovered that when a combination of PG-based surfactant and lecithin was applied to a water-in-oil formulation, the viscosity and hardness were improved, thereby improving stability. In addition, as a surfactant that replaces the PEG-based surfactant, it was discovered that the stability was further improved when a PG-based surfactant and a sorbitan-based surfactant were used together, and the present invention was completed.
따라서, 본 발명은 레시틴, PG계 계면활성제, 소르비탄계 계면활성제 및 점증제를 유효성분으로 함유하는 안정도가 개선된 유중수형 화장료 조성물에 관한 것이다.Therefore, the present invention relates to a water-in-oil cosmetic composition with improved stability containing lecithin, a PG-based surfactant, a sorbitan-based surfactant, and a thickener as active ingredients.
본 발명의 조성물에서 레시틴은 유중수형 제형의 유화 안정화제로서 함유된다. In the composition of the present invention, lecithin is contained as an emulsion stabilizer for the water-in-oil type formulation.
본 발명에서 "유화 안정화제"라 함은, 오일을 외상으로 함유하는 유중수형 제형 형성 시, 외상에서 오일 층의 분리를 억제하고, 조성물의 점도 및 경도를 상승시켜서 제형 안정도를 확보하는 작용을 하는 것을 말한다. 나아가, 장시간 경과 후, 또는 고온 및 저온 조건에서도 오일 층이 분리되지 않고, 경도에 큰 변화가 없어 경시적 안정도를 유지하는 작용을 하는 것을 말한다.In the present invention, "emulsion stabilizer" refers to an agent that acts to ensure formulation stability by suppressing separation of the oil layer from the outer layer and increasing the viscosity and hardness of the composition when forming a water-in-oil formulation containing oil on the outer layer. says that Furthermore, it means that the oil layer does not separate even after a long period of time or under high and low temperature conditions, and there is no significant change in hardness, thereby maintaining stability over time.
일반적으로 레시틴은 아래의 화학식 I로 나타내는 분자 구조를 갖는다. 인산 및 콜린 등의 친수성 성분이 글리세롤에 결합되어 있고, 반대쪽에는 소수성 아실기가 결합된 구조를 하고 있어서 계면활성제의 특징을 가지고 있다. Generally, lecithin has a molecular structure represented by Chemical Formula I below. It has the characteristics of a surfactant because it has a structure in which hydrophilic components such as phosphoric acid and choline are bonded to glycerol, and a hydrophobic acyl group is bonded to the other side.
[화학식 I][Formula I]
레시틴은 이러한 구조적 특징을 지녀 유화제로 사용될 수 있으나, 단독으로는 유화력이 약한 편이어서 화장품에서는 보조적인 역할로 사용된다. 또한, 보조 유화제로 사용될 경우에도 주로 수중유형 제형에 사용되고 있다. 본 발명에서는 수중유형 화장료의 보조 유화제로 사용되던 레시틴을, 특정 계면활성제의 조합 및 점증제와 병용하면, 유중수형 제형의 안정도를 향상시킬 수 있음을 발견하였다.Lecithin has these structural characteristics and can be used as an emulsifier, but it has weak emulsifying power on its own, so it is used in cosmetics in an auxiliary role. Additionally, when used as an auxiliary emulsifier, it is mainly used in oil-in-water formulations. In the present invention, it was discovered that the stability of water-in-oil type formulations could be improved by using lecithin, which was used as an auxiliary emulsifier for oil-in-water cosmetics, in combination with a specific surfactant and thickener.
본 발명에 따른 유중수형 조성물에 함유될 수 있는 레시틴은 특별히 제한되지는 않으나, 입수 용이성 등을 고려하여 대두(soybean) 유래 수소첨가 레시틴을 사용할 수 있다.The lecithin that can be contained in the water-in-oil composition according to the present invention is not particularly limited, but hydrogenated lecithin derived from soybeans can be used considering ease of availability.

If the lecithin content is less than 0.05% by weight, the improvement in viscosity and hardness is not noticeable and stability cannot be guaranteed, and if it exceeds 5% by weight, the hydrophilicity is too strong and the formulation is not properly formed, which is undesirable.
본 발명에 따른 유중수형 조성물에서, PEG계 계면활성제를 대체하는 계면활성제로는 PG계 계면활성제 및 소르비탄계 계면활성제의 조합을 사용할 수 있다.In the water-in-oil composition according to the present invention, a combination of a PG-based surfactant and a sorbitan-based surfactant can be used as a surfactant replacing the PEG-based surfactant.

일반적으로 유중수형 제형의 외상의 오일을 점증하기가 쉽지 않지만, 본 발명에 따른 조성물에서 상기 점증제를 레시틴과 PG계 계면활성제 및 소르비탄계 계면활성제와 병용 시 상기 서술한 비율과 서술한 조합을 활용하면, 레시틴이 상기 점증제의 점증력을 높여줄 수 있다. 또한, 상기 점증제의 병용은 레시틴의 약한 유화력과 PG계 계면활성제 및 소르비탄계 계면활성제의 상호작용에 의하여 보다 촘촘하고 단단한 계면막을 형성하여 점도 및 경도를 상승시키게 되어, 유중수형 제형의 안정도를 더욱 높이는 역할을 한다. 본 발명의 유중수형 조성물에서 점증제를 함유하지 않으면 충분한 점도 및 경도를 확보할 수 없어서 안정도를 담보할 수 없는 문제가 발생할 수 있다. In general, it is not easy to thicken the external oil of a water-in-oil type formulation, but when the thickener is used in combination with lecithin, a PG-based surfactant, and a sorbitan-based surfactant in the composition according to the present invention, the above-described ratio and the above-described combination are used. When used, lecithin can increase the thickening power of the thickener. In addition, the combined use of the above thickener increases the viscosity and hardness by forming a denser and harder interfacial film due to the interaction between the weak emulsifying power of lecithin and the PG-based surfactant and sorbitan-based surfactant, thereby increasing the stability of the water-in-oil type formulation. It serves to further elevate it. If the water-in-oil composition of the present invention does not contain a thickener, sufficient viscosity and hardness cannot be secured, and thus stability may not be guaranteed.

[시험예 1] 조성물의 제형안정도 평가[Test Example 1] Evaluation of formulation stability of composition
상기 실시예 1~2 및 비교예 1~7의 조성물에 대하여 제형안정도를 평가하였다. 초기 점도는 Brookfield viscometer(spindle no 4, 12rpm, 2min, 25℃)를 사용하여 평가하였고, 측정된 단위는 cps이다. 경도는 SUN RHEOMETER COMPAC-100의 경도측정방법을 사용하여 평가하였고, 측정된 단위는 g/m2이다.The formulation stability of the compositions of Examples 1 to 2 and Comparative Examples 1 to 7 was evaluated.
