The single emulsifier, compound emulsifier, thickener in the acidic system were screened, and the long-term thermal stability was investigated. The experimental results show that when the ether emulsifier, NIKKOL BC-150 and MONTANOV 68, is compounded in a mass ratio of 2:1 and the thickener is SEPIPLUS 400, the obtained product has good thermal stability, and its functional ingredients (tea tree oil and salicylic acid) did not change significantly at high temperatures.展开更多
