Sensory evaluation of a body lotion formulated with hot spring water from Deokgu, Korea
The purpose of this study was to evaluate hot spring water (HSW) from Deokgu as a cosmetic ingredient in the preparation of a body lotion. The HSW was tested for its suitability as an aqueous phase main component. Microbiological and chemical stability tests of the HSW were carried out. Microorganisms including E. coli were not detected or detected below the detection limits, and no harmful heavy metals were found. The cytotoxicity of the HSW was also considered, and its pH determined over a period of three months. Further, sensory characteristics were assessed for consumer acceptance by performing sensory tests on body lotions formulated using either Deokgu HSW or distilled water. Skin moisturization, irritation and tension reinforcement were found to be enhanced when using the HSW lotion rather than that formulated with distilled water. Taken together, the results of this study show that the use of HSW in cosmetic formulations contributes to the efficacy of these products. yo yag iyeonguyimogjeogeunbadirosyeonjejosihwajangpumceomgajeroseoyideogguonceonsureulpyeonggahagiwihamida. juyosuyongseongguseongseongbuneu roseoyi onceonsuyi jeoghabseongeul siheomhayeossda. onceonsuyi misaengmul mic hwahagjeog anjeonseong siheomi suhaengdoeeossda. daejanggyuneul biroshan misaengmuleun geomculdoejianhassgeonageomculhandoiharogeomculdoeeosseumyeo, yuhaehanjunggeumsogeunjeonhyeogeomculdoejianhassda. onceonsuyisepodogseongipyeonggadoeeosseu myeo, onceonsuyi pH byeonhwareul 3daldonganceugjeonghayeossda. ddohandeogguonceonsumicjeungryusurojejodoenbadirosyeonedaehaeseogwanneungsiheomeulsuhaenghameu rosseo sobijayi jeoghabseongeul gwanneungteugseong bunseogeul tonghayeo pyeonggahayeossda. jeungryusuro jejodoen badirosyeonboda onceonsureul sayonghan badirosyeoneul pibue jeogyonghayeosseulddae, pibuboseub, pibuteureobeulmic pibu jangbyeogganghwaga jeungjindoeeossda. jonghabhae boasseul ddae, i yeonguyi gyeolgwaneun hwajangpum jejoe isseoseo onceonsureul sayonghaneun geoseun hwajangpumyi hyoneungeul jeungjinsikil su isseumeul boyeo junda.
