Abstract

Since minerals are in ionic forms in aqueous phase (like deep sea water), it is very hard to incorporate concentrated minerals in gel like cosmetic formulations which are generally composed of carbomer or acrylates polymer. In this study, we invented a salt-resistant network formulation made of silicon copolyol. It was found that the network formulation traps minerals (especially from marine) in a mesh-like silicone copolyol structure. Since the mineral-containing formulation makes a very thin film on the skin, minerals could be easily absorbed into stratum corneum. In 6 weeks in vivo test, it was found that the novel mineral formulation increased the amounts of amino acids, major components of natural moisturizing factors (NMFs), as well as levels of minerals. It was also found that the moisture contents and the brightness of the skin increased.

미네랄은 이온 상태로 존재하기 때문에, 카보머나 아크릴레이트 계 점증 시스템의 저점도 가용화 제형에서는 고농도로 안정화하기 어렵다. 본 연구에서는 젤 에센스 제형 내 고농도의 미네랄을 안정화하기 위하여, 염류에 안정한 실리콘 코폴리올을 이용한 네트워크 필름을 만들고, 네트워크 내에 미네랄을 고농도로 포집하여 피부에 오랜 시간 동안 고농도의 미네랄이 천천히 피부에 흡수될 수 있도록 제형을 설계하였다. 설계한 최적의 제형을 시료로 이용하여 6주간의 임상실험을 진행하였으며, 그 결과 피부 각질층의 미네랄 함량이 증가하고, 아미노산이 증가함으로써 각질층의 수분량이 증가하여 피부 투명도가 증가하였고 묵은 각질이 탈락하고 각질층이 정돈되어 피부 칙칙함과 피부 밝기가 개선됨을 확인하였다.
