화장품은 그 어떤 제품보다도 소비자가 사용 시 느끼는 관능특성 및 그에 대한 만족도가 중요한 제품이다. 자연스러우면서도 가벼운 메이컵이 유행함에 따라 페이스 파우더를 사용하는 소비자의 비중이 높아지고 그에 따라 다양한 관능특성을 가진 페이스 파우더들이 개발되고 있다. 사전 조사에 따르면 페이스 파우더 사용자들의 사용이유는 자연스러운 화장 및 가벼운 화장, 화사해 보임(블루밍 효과) 등이 주를 이루며 페이스 파우더 사용 시에 주요하게 느끼는 관능특성으로는 파우더 입자에 관한 사항과 화장상태에 관한 사항이 동시에 고려되는 것으로 나타났다. 이에 평상시에 페이스파우더를 주로 사용하는 여성들을 대상으로 다양한 페이스파우더들을 실제 화장단계에 따라 사용하면서 인지되는 페이스 파우더의 관능특성들을 도출하게 한 결과 중 19가지 관능특성 평가 용어가 도출되었으며 이 용어들은 다시 입자 및 도포 요인/촉촉함 및 매트함 요인/색상 및 블루밍 요인의 세가지 요인으로 분류되었다. 이러한 페이스파우더의 주요 관능특징요인과 소비자들이 중요하게 생각하는 관능특성을 적절히 조합하여 각각의 소비자군들이 선호하는 관능속성의 제품을 설계하고 평가할 수 있는 평가방법을 개발하였고 주후 제품개발에 활용하고자 한다.

In the field of makeup cosmetics, especially, powder-based foundations such as two-way cake, pact and face powder, the quality of which is known to be strongly influenced by the properties of powder, surface treatment technology is widely used as a method to improve the various characteristics of powder texture, wear properties, dispersion ability and so on. The two-way cake or pressed-powder foundation is one of the familiar makeup products in Asian market for deep covering and finishing purpose. In spite of the relent progress in surface modification method such as composition of powders with different characteristics and application of a diversity of coating ingredient (metal soap, amino acid, silicone and fluorine), this product possess a technical difficulty to enhance both of the adhesion power and spreadability on the skin in addition to potential claim of consumer about heavy or thick feeling. This article is covering the preparation and coating method of nano-vesicle that mimic the double-layered lipid lamellar structure existing between the corneocytes of the stratum corneum in the skin for the purpose of improving both of two important physical characteristic of two-way cake, spreadability and adhering force to skin, and obtining better affinity to skin. Nano-vesicle was prepared using the high-pressure emulsifying process of lecithin, pseudo ceramide, butylene glycol and tocopheryl acetate. This nano-sized emulsion was added to powder-dispersed aqueous phase together with bivalent metal salt solution and then the filtering and drying procedure was followed to yield the nano-vesicle coated powder. The amount of nano-vesicle coated on the powder was able to regulated by the concentration of metal salt and this novel powder showed the lower friction coefficient, more uniform condition of application and higher adhesive powder comparing with the alkyl silane treated powder from the test result of spreadability and wear properties using friction meter and air jet method. Two-wav cake containing newly developed coated powder with nano-vesicle showed the similar advantages in the frictional and adhesive characteristics.

BGsome coating on the surface of illite powder was attempted to impart skin affinity and improve various characteristics of the powder for makeup cosmetics. BGsome is a type of hydrated liquid crystalline vesicles prepared by the hydration of 1,3-butylene glycol (BG) dissolved lecithin. BGsome droplets were coated through wet process and the coated powders were analyzed by TGA, SEM, and particle size measurements. Effect of BGsome coating on the physical properties, such as flow-ability, dispersibility, spreadability, and adhesion, were examined. The repose angle of BGsome-coated illite was decreased, which means that BGsome coating improves the flowability of the powder. Dispersibility, spreadability, and adhesion of the coated illite were also improved remarkably. The result of adhesion tests showed that the BGsome-coated illite was evenly adhered onto artificial leather surface with almost no lumps. The flowability, dispersibility, spreadability and adhesion of face powders containing the BGsome-coated illite were also improved.
