结合剂、乳化剂、香料。人工合成酯,低分子量的单酯类,可增加产品的易涂性,并减轻油腻感,作为混合剂及香料的溶剂,也可保湿及柔润皮肤,具有刺激性,有导致青春痘之可能。

属化学制造之合成脂,清爽、易推开,无一般植物油之黏腻感,因分子小,易渗入毛孔中清洁油脂类污垢,作为卸妆用途时较果非常良好,但同时也会渗透角质细胞,过度使用会使皮肤角化、变得粗糙蜡黄,拒绝指数为 4/5(越高越不好)[1]。

并常添加于多种化妆品中作为溶剂,面疱发生性为 4/5(越高越不好),皮肤刺激性为 1/5(越高越不好)[1]。

WHAT IS IT? A compound of isopropyl alcohol and palmitic acid that is used commonly as a thickening agent. It is an easily spreadable man-made thickening and emollient agent; its main function is to make products feel soft and look shiny. Isopropyl myristate can often be found in beauty products as well and is a major ingredient in a can of penetrating rust remover, Liquid Wrench.

HEALTH RISK: Known to be comedogenic (pore-clogging), it also causes flare-ups of pustular acne. The thickness of the chemicals in isopropyl palmitate can deprive the skin of nutrients such as as oxygen. If the skin doesn’t breathe, your pores can become clogged and healthy skin cells can die. This can also lead to dry, flaky skin. In addition, industry tests on rabbits indicate the chemical can cause skin irritation and dermatitis. This is a cheap way to make products feel nice and last longer but it’s bad for your skin, especially if you’re prone to breakouts!
