通過三種美白劑的復配,同時加入綠色組分和納米材料,根據美白功效,找到最佳配方。按照課題要求,本實驗考慮日光因素,選用天然蘆薈膠,并加入紅花提取液和白芷提取液

摘要:盡管目前國外已有相關美白劑復配的報道,但對復配后協同效應的研究則鮮有報道。本課題通過三種美白劑的復配,同時加入綠色組分和納米材料,根據美白功效,找到最佳配方。按照課題要求,本實驗考慮日光因素,選用天然蘆薈膠,并加入紅花提取液和白芷提取液,還嘗試了納米氧化鋅的效果;而對于復配,本實驗選用的是曲酸雙棕櫚酸酯、甘草提取液和熊果苷的復配,來代替單一的熊果苷,其美白效果有了顯著的提高。納米材料也因為其獨特的功效,在本實驗中有了一定的可取性。根據實驗結果,配比1是抑制效果最好的配方,而優化2美白劑的抑制率達到了最高,本課題中最佳的美白劑配方是:十八醇12%,甘油15%,異丙醇5%,三乙醇胺0.5%,表面活性劑44%,防腐劑1%,香精0.5%,白芷提取液4%,紅花提取液4%,蘆薈膠2%,熊果苷3%,納米氧化鋅2%,曲酸雙棕櫚酸酯4%,甘草提取物3%。35686

Study on Application of green whitening agent in cosmetics
Abstract:Although the existing foreign related whitening compound reported, but research on compound synergistic effect is rarely reported. Through the combination of three kinds of whitening agents, we also add the green component and nano material, according to whitening effect, find the best formula.In accordance with the requirements of the subject, this study consider daylight factor, selection of natural aloe vera gel,adding safflower extract and Radix Angelicae extract,the effect of nanometer zinc oxide was also attempted;and for the compound, the selected compound is kojic dipalmitate, licorice extract and arbutin, instead of a single arbutin,it’s whitening effect has been significantly improved.Because of its unique effect,in this experiment nano material has some merit.According to the experimental results, the best formula is 1, while the inhibition rate of the optimized 2 whitening agent is the highest, and the best whitening agent formula is:Octadecyl alcohol 12%, 15% glycerol, 5% isopropyl alcohol, triethanolamine 0.5%,Surfactant 44%, preservatives 1%, 0.5% essence, dahurian angelica root extract liquid 4%, safflower extract liquid 4%, aloe vera gel 2%, arbutin 3%, 2% of nano ZnO, Kojic dipalmitate 4%,licorice extract 3%. 源¥自%六:維;論-文'網=www.aftnzs.live
