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 cosmetic composition having improved stability by containing lecithin, a surfactant, and a thickener as an active ingredient. More specifically, the present invention relates to a water-in-oil cosmetic composition containing lecithin as an emulsifying stabilizer, while using a PG-based surfactant and a sorbitan-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 the water-in-oil type (W/O) formulation, it is difficult to increase the oil of the trauma, so the viscosity and hardness of the formulation tend to drop over time and tend to be easily separated.
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 type (O/W) emulsification stabilization mechanism has two main processes. 1) Stabilization of emulsified particles: The emulsification film is made firm with a surfactant, higher alcohol, and acid to prevent coalescence of colloidal particles. 2) Stabilization of the emulsified particles formed: prevents creaming and flocculation of the emulsified particles by increasing the number of traumatic water parts.
[O/W 화장료 제형의 유화 안정화 메커니즘][Emulsification 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 the water-in-oil formulation, since it is difficult to increase the oil of the trauma, it is difficult to prevent coalescence and aggregation between particles among the above principles. As a result, the viscosity and hardness of the formulation drop over time and eventually the formulation separates. This 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, a PEG (polyethylene glycol)-based surfactant is weaker than other surfactants for water-in-oil, but can form a stable interfacial film, and raw materials with HLB values in various sections can be used for cosmetics. It has been widely used in the art despite some instability, considering various conveniences such as commercialization. However, in recent years, the use of PEG-based surfactants is gradually decreasing due to increased consumer interest in safety, and thus it has become more difficult to secure the stability of water-in-oil formulations. Therefore, there is a need to develop a water-in-oil cosmetic with improved formulation stability without using a PEG-based surfactant.
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, an object of the present invention is to provide a water-in-oil cosmetic composition having 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.The present inventors surprisingly use a polyglyceryl (PG) surfactant and a sorbitan surfactant instead of a PEG-based surfactant, while applying lecithin to the water-in-oil formulation improves viscosity and hardness to improve stability. The improvement was found 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 cosmetic composition with improved stability containing lecithin, PG-based surfactant, sorbitan-based surfactant, and thickener as an active ingredient.
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 having improved stability by suppressing separation of the oil layer and increasing viscosity and hardness by using lecithin as an emulsifying stabilizer of the water-in-oil composition. In addition, it is possible to provide a water-in-oil cosmetic composition that maintains stability over time without being separated even during long-term storage and in harsh conditions of high/low temperature. In addition, it is possible to provide a water-in-oil cosmetic composition that does not contain a PEG-based surfactant, and has improved skin feel while improving skin feel.
도 1은 본 발명의 실시예 1~2와 비교예 1~7의 상온 방치 시(48시간 경과) 제형 변화를 비교한 사진이다.1 is a photograph comparing the changes in formulations at room temperature (48 hours) in Examples 1 to 2 and Comparative Examples 1 to 7 of the present invention.
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 it is intended to be used instead of a PEG-based surfactant. The PG-based surfactant is difficult to sufficiently secure the stability of the water-in-oil type formulation with the PG-based surfactant alone. In addition, lecithin has weak emulsifying power and has been used as an auxiliary component 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 have found that when a combination of a PG-based surfactant and lecithin is applied to a water-in-oil formulation, viscosity and hardness are improved to improve stability. In addition, as a surfactant that replaces the PEG-based surfactant, it was found that the stability is further improved when a PG-based surfactant and a sorbitan-based surfactant are used in combination to complete the present invention.
따라서, 본 발명은 레시틴, PG계 계면활성제, 소르비탄계 계면활성제 및 점증제를 유효성분으로 함유하는 안정도가 개선된 유중수형 화장료 조성물에 관한 것이다.Accordingly, the present invention relates to an improved water-in-oil cosmetic composition containing lecithin, a PG surfactant, a sorbitan surfactant, and a thickener as an active ingredient.
본 발명의 조성물에서 레시틴은 유중수형 제형의 유화 안정화제로서 함유된다. Lecithin in the composition of the present invention is contained as an emulsifying stabilizer in water-in-oil formulations.
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, the term "emulsification stabilizer", when forming a water-in-oil formulation containing an oil as a trauma, suppresses the separation of the oil layer from the trauma, and increases the viscosity and hardness of the composition to function to secure formulation stability. Say things. Furthermore, it means that the oil layer does not separate even after a long period of time has elapsed or under high temperature and low temperature conditions, and there is no significant change in hardness to maintain 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 the formula (I) below. Hydrophilic components such as phosphoric acid and choline are bound to glycerol, and on the other side, hydrophobic acyl groups are combined to have the characteristics of a surfactant.
[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 a weak emulsifying power alone, so it is used as an auxiliary role in cosmetics. Also, when used as an auxiliary emulsifier, it is mainly used in oil-in-water formulations. In the present invention, it was found that the stability of the water-in-oil formulation can be improved by using lecithin, which was used as an auxiliary emulsifier for oil-in-water cosmetic, in combination with a specific surfactant combination and a 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 may be contained in the water-in-oil composition according to the present invention is not particularly limited, but considering the availability and the like, hydrogenated lecithin derived from soybean may be used.

If the content of the lecithin is less than 0.05% by weight, the viscosity and hardness is not improved, so stability cannot be guaranteed. If it is more than 5% by weight, the hydrophilicity is too strong to form the formulation, which is not preferable.
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 may be used as a surfactant to replace the PEG-based surfactant.
상기 PG계 계면활성제의 예로는 일반적으로 화장품의 계면활성제로 사용되는 모든 폴리글리세릴계 화합물을 포함할 수 있다. 하지만 그 중에서도 유중수형 조성물에 사용하기 위하여 HLB 값은 7 이하이어야 하며, 상기 PG계 계면활성제는 유상에서 60℃ 이하에 용해되는 특징을 갖는 것이 바람직하다.Examples of the PG-based surfactant may include all polyglyceryl-based compounds that are generally used as surfactants in cosmetics. However, among them, for use in a water-in-oil composition, the HLB value should be 7 or less, and it is preferable that the PG-based surfactant has a characteristic of being dissolved at 60° C. or less in an oil phase.
또한, 상기 소르비탄계 계면활성제의 예로는 일반적으로 화장품의 계면활성제로 사용되는 모든 소르비탄 에스테르계 화합물을 포함할 수 있다. 하지만 그 중에서도 유중수형 조성물에 사용하기 위하여 HLB 값은 7 이하이어야 하며, 상기 소르비탄계 계면활성제는 유상에서 60℃ 이하에 용해되는 특징을 갖는 것이 바람직하다.Further, examples of the sorbitan-based surfactant may include all sorbitan ester-based compounds that are generally used as surfactants in cosmetics. However, among them, for use in a water-in-oil composition, the HLB value should be 7 or less, and the sorbitan-based surfactant preferably has a characteristic of being dissolved at 60° C. or less in an oil phase.

본 발명의 일 구현예에 따르면, 상기 PG계 계면활성제 및 소르비탄계 계면활성제는 조성물 총 중량에 대하여, 0.05 내지 10 중량% 함유되며, 바람직하게는 0.1 내지 5 중량%인, 안정도가 개선된 유중수형 화장료 조성물을 제공할 수 있다. 상기 PG계 계면활성제 및 소르비탄계 계면활성제의 함량이 0.05 중량% 미만이면, 안정적인 계면이 형성되지 않아 안정도를 담보할 수 없고, 5 중량% 초과이면, 친유성이 너무 강하여 불안정한 제형이 형성되어 바람직하지 않다.According to one embodiment of the present invention, the PG-based surfactant and the sorbitan-based surfactant are contained in an amount of 0.05 to 10% by weight, and preferably 0.1 to 5% by weight, based on the total weight of the composition. A male cosmetic composition can be provided. When the content of the PG-based surfactant and the sorbitan-based surfactant is less than 0.05% by weight, a stable interface is not formed and thus stability cannot be guaranteed. If it is more than 5% by weight, an unstable formulation is formed because the lipophilic property is too strong. Does not.
본 발명의 일 구현예에 따르면, 상기 PG계 계면활성제 및 소르비탄계 계면활성제는 조성물 총 중량에 대하여, 1:1 내지 5:1의 중량비로 함유되며, 바람직하게는 2:1 내지 3:1의 중량비인, 안정도가 개선된 유중수형 화장료 조성물을 제공할 수 있다. 상기 PG계 계면활성제 대 소르비탄계 계면활성제의 중량비가 1:1 미만이면, 친유성이 너무 강하여 불안정한 제형이 형성되고, 5:1 초과이면, 제형 내 응집 현상이 발생하여 바람직하지 않다.According to an embodiment of the present invention, the PG-based surfactant and sorbitan-based surfactant are contained in a weight ratio of 1:1 to 5:1 with respect to the total weight of the composition, and preferably 2:1 to 3:1 It is possible to provide a water-in-oil cosmetic composition having improved weight ratio and stability. When the weight ratio of the PG-based surfactant to the sorbitan-based surfactant is less than 1:1, the lipophilic property is too strong to form an unstable formulation, and when it is more than 5:1, aggregation in the formulation occurs, which is not preferable.
본 발명에 따른 유중수형 조성물은, 레시틴과 PG계 계면활성제 및 소르비탄계 계면활성제 외에도 점증제를 함유함으로써 외상의 오일을 효과적으로 점증하여 안정도를 더욱 개선할 수 있다.The water-in-oil composition according to the present invention can further improve the stability by effectively increasing the oil of the trauma by containing a thickener in addition to a lecithin and a PG surfactant and a sorbitan surfactant.
