Ammonium laureth sulphate 此物质含乙醚且易被皮肤吸收，常加入于泡泡沐浴精和洗髮精中，对皮肤有伤害，有毒性，致癌物质，会有诱发有机体突变的可能。
The Human and Environmental Risk Assessment (HERA) project performed a thorough investigation of all alkyl sulfates, as such the results they found apply directly to ALS. Most alkyl sulfates exhibit low acute oral toxicity, no toxicity through exposure to the skin, concentration dependent skin irritation, and concentration dependent eye-irritation. They do not sensitize the skin and did not appear to be carcinogenic in a two year study on rats. The report found that longer carbon chains (16–18) were less irritating to the skin than chains of 12–15 carbons in length. In addition, concentrations below 1% were essentially non-irritating while concentrations greater than 10% produced moderate to strong irritation of the skin.
底下(楼上?)这误导人的迴响怎么没被删除？
ALES具有刺激性，但并非致癌物，请不要随便乱讲。
请问这个界面活性剂属于哪一个类别，是阴离子型、阳离子型、两性型、非离子型哪一种?
