Preparation and Analysis of Influencing Factors of Aloe Vera Hand Cream
In order to apply aloe extract to hand cream,single factor method was used to optimize the prescription process.The effects of oil phase composition and ratio,oil-water phase ratio,emulsifier composition and dosage,emulsification temperature and other factors in the prescription were analyzed,and the evaluation indexes of the product were sensory evaluation,heat and cold resistance,stratification experiment and irritation.The results showed that the optimum conditions were as follows:the oil phase consisted of the composition of liquid paraffin(10%)and petroleum jelly(17%),the ratio of oil-water phase was 1︰2,the emulsifier was selected with the mixture of 16-octadecyl alcohol(3%),glycerol monostearate(7%)and tween-60(7%),and the mixing temperature of oil-water phase was 60~80 ℃.The aloe vera hand cream prepared under this condition has uniform color,refreshing texture,good cold and heat resistance and stability,which provides a theoretical reference for the research of aloe vera extract in skin care industry.
