摘要：随着口红的普及，人们对于口红的构成和影响口红的内在因素产生了兴趣。由此，本文从口红的膏体原料作为研究对象，对基质原料油和蜡的凝固点以及相容性现象进行分析。在得到单一蜡质的基础上，加入不同种类和不同量的油脂，对其进行凝固点的比较和分析，再选择部分样品在室温或者45℃恒温箱静置一段时间，观察出油状况，分析加入量和温度对于原料之间的相互影响。实验结果表明：熔点仪测得的数据较为可靠，混合油蜡的熔点很大程度上取决于蜡质原料，熔点较接近该蜡质，与油脂的相关程度不大，且在高温熔融时，现象都呈透明状液体，混合油蜡较易出油。

Factors affecting the solidifying point and rheology of lipstick

Abstract: With the popularity of the lipstick, people are interested in the composition and the internal factors of lipsticks. Therefore, as the research object, the freezing point and compatibility phenomenon of matrix raw oil and wax are analyzed from the raw materials of the lipstick. On the basis of the single wax, adding different kinds of oil to compare and analyze the solidification  point, then  selecting  some samples  at  room temperature  or 45 ℃ constant

temperature box for a period of time, observing the oil and wax condition, analyzing the interaction between the amount and temperature of the raw materials. The experimental results show that the data obtained by the melting point instrument are more reliable. The melting point of the mixed oil wax depends largely on the wax material, and the melting point is close to the wax. It is transparent when the mixed oil wax was melt at high temperature. The mixed oil wax is easier to produce oil.

KeyWords: Lipstick; oil; wax; solidifying point
