看了下这个产品介绍，有没有mm给解释下coconut derived cleansers(SLS)是什么?那个产品的说明： Our special formulation for hands uses gentle coconut derived cleansers, vitamin E and botanical extracts - including chamomile and aloe - to gently cleanse, sooth and recondition skin. 我在其他号称温和的产品上也看到SLS后标注derived from coconut，这个是什么意思呢？coconut里能进化出SLS不？Kiehl's的氨基酸洗发乳不含SLS，但我每次看到这个derived from coconut就不懂了。。
