芦荟提取物对水包油型乳液的抗氧化性能影响

Effects of Aloes Extract on Anti-Oxidation Performance of Oil-in Water Emulsion

在水包油乳液中添加芦荟提取物,考查了芦荟提取物的添加量、温度和紫外光对乳液的过氧化值以及羟基自由基清除能力的影响.结果表明:室温下添加8 mL芦荟提取物放置5 h时,乳液的过氧化值比未添加小20.64%;室温下用紫外光照射5 h时,添加芦荟提取物的乳液的过氧化值比未添加小16.73%;40℃温度下加热5 h时,添加4 mL芦荟提取物的乳液的过氧化值比未添加小21.76%.羟基自由基清除能力实验说明乳液添加芦荟提取物后,羟基自由基清除率是未加的5.5倍.

Adding aloes extracts in oil-in water emulsion,influences of aloes extracts dosage,temperature and ultraviolet light on peroxide value of emulsion cosmetics and hydroxyl free radical scavenging capacity were investigated.The results showed that the peroxide value of emulsion with addition of 8 mL aloes extracts for 5 hours decreased by 20.64% compared with that without addition of aloes extract.After 5 hours of UV irradiation,the peroxide values of emulsion with addition of aloes extracts decreased by 16.73...
