Abstract

In this experiment, the optimum concentration of polyols which were used for making transparent soaps was determined using design of experiment (DOE) method. Dipropylene glycol and 1,3 butylene glycol with short chains enhanced the transparency of soap, however, polyethylene glycol 400, glycerin and diglycerin made the soap opaque. The hardness of soap was increased as increasing the concentration of propylene glycol, diglycerin, dipropylene glycol and polyethylene glycol 400. The hardness, transparency, absorbance of water, and friction solubility could be optimized by controlling the concentration of dipropylene glycol, polyetylene glycol, sugar, and triethanolamine.

본 실험에서는 투명비누를 만드는데 사용되는 폴리올의 최적 농도를 실험계획법을 이용하여 결정하였다. 짧은 사슬을 보유한 디프로필렌글리콜과 1,3 부틸렌글리콜은 비누의 투명도를 증가시켰으나 폴리에틸렌글리콜 400, 글리세린과 디글리세린은 비누를 불투명하게 하였다. 프로필렌글리콜, 디글리세린, 디프로필렌글리콜 및 폴리에틸렌글리콜의 농도를 증가시키면 비누의 경도는 증가하였다. 경도, 투명도, 물의 흡수성 및 마찰 용해도는 디프로필렌글리콜, 폴리에틸렌글리콜, 설탕과 트리에탄올아민의 농도를 조절하여 최적화할 수 있었다.
