초록

본 연구에서는 수용액상에서 스클레로글루칸의 레올로지 성질을 0.1 ~ 2 wt.%의 농도에서 레오미터와 점도계를 이용하여 측정하였다. 스클레로글루칸 겔은 다양한 염과 pH에서 강한 점증력을 보이며, 식물성 스쿠알란을 함유한 고분자 분산계에서 스클레로글루칸은 강한 오일 분산성질을 보인다. 또한 스클레로글루칸과 로커스트빈검 혼합물의 시너지효과를 관찰하였으며, 스클레로글루칸과 로커스트빈검의 혼합비율이 5 : 5일 때 가장 높은 점증 효과를 나타냈다.이들 연구결과는 다양한 화장품 제형을 위한 점증제로써 스클레로글루칸의 가능성을 보여줄 것이다

The rheological properties of the aqueous solution of scleroglucan industrially produced by Sclerotium rolfsii at concentrations ranging from 0.1 % to 2 % (w/w) were determined by using brookfield viscometer and rheometer. Gel matrices of scleroglucans were stable over a wide range of pH and ionic strength in the aqueous medium. In the oil dispersion with phytosqualane in oil phase and three kinds of thickening agent in aqueous phase, scleroglucan showed the highest dispersion properties. The synergistic effect between scleroglucan and locust bean gum was also examined. The highest viscosity was obtained for the solution mixture at scleroglucan/locust bean gum weight ratio of 5 : 5. The results of this study suggest the potential of scleroglucan as thickner for a wide variety of cosmetic formulations.
