有良好的起泡及去油作用,清洁力极佳,常使用于个人清洁用品中,但用于直接接触肌肤性产品时,容易带走肌肤表层之溼气,而导致敏感性肌肤(如化学敏感、溼疹、粉刺、皮肤炎、癣类)者产生不适及加重刺激[1];但若添加于间接接触肌肤产品时(如洗衣店之清洁剂),则不会有此问题[1]。

在CIR(Cosmetic Ingredient Review)的评估报告中,有明确造成肌肤或眼周粘膜刺激性的可能。

烷基醚硫酸盐,烷基硫酸盐,市面上90%的贩售洗髮精,护髮乳中均含它,它会损害毛囊,阻碍头髮生长,它亦常用在牙膏、乳液、乳霜和清洁剂中,它会渗入眼睛、脑、肝脏中并会长期积存,会使细胞膜慢慢变薄,改变基因的讯息传送(造成身体基因的突变),伤害免疫系统造成眼睛变的看不见,形成白内障,眼睛无法正常的痊癒,阻碍眼睛痊癒的过程,研究报告显示此成份添加于化妆品和食品营养品中会使成份硝酸化,造成致癌物成为有毒物质,所有这些成份会进入人体的循环系统,经由洗髮精和口腔刷洗中摄入,这些成份会滞留在肝脏、心脏和眼睛、肾脏、肌肉中达数年之久,它们会造成眼睛发炎、起疹子,造成掉髮、头皮屑和过敏现象。

邱品齐医师对于 SLES &SLS 两种成分的介绍与释疑 :http://tw.myblog.yahoo.com/skindocchiu-cosmeticfact/article?mid=6088&prev=6907&next=5907&l=f&fid=28 .

撷取部分重点:


于是目前结论是无论是SLS或是SLES本身都不是致癌性成份(Carcinogen)

如果要以最严格挑剔的论点来看的话

应该说SLS高浓度长期使用可能会有促癌的可能性

而制造SLES时所产生的1,4-dioxane副产物有可能会有致癌的可能性

但这两种状况以目前一般的使用情形来说几乎是可以不需担心的

为何我只要洗,含有 sls、sles、als、 Cocoamidopropyl Betaine 的洗髮精 都会过敏(头皮痒 头皮皮肤过敏发炎 头皮屑),而且有Cocoamidopropyl Betaine的洗髮精 洗了好像都会有银屑(有时头髮干后 头皮感觉有些东西 屑之类),

特别是那种洗髮精sls、Cocoamidopropyl Betaine 洗了,没多久 头皮会痒 皮肤过敏发炎,有大大 能介绍 不会过敏的洗髮精吗?

有些洗髮精不知什么原因 什么成份过敏(或着有毒的成份),会造成眼睛 很痛 连带头也跟着痛,而且痛到 睡觉 根本睡不着。

个人经验建议:大油田使用适量添加SLS的洗发产品应该挺好的,因为清洁能力真的很强,但的确这成分刺激性也强,我用含有SLS的洗发产品时手部皮肤能干到脱皮,而含有SLS 的牙膏也会让我刷牙后口腔内壁脱皮,虽然像我这样容易过敏的人也是少数,但还是建议在有其他选择的时候尽量避开这个成分,比如洗发水可以买在产品包装上明确标明不含SLS的,而牙膏也可以选择非起泡牙膏。

There has been a great of misinformation about sodium lauryl sulfate (SLS) being circulated on the Internet. Used primarily as a detergent cleansing agent SLS can be derived from coconut. Although it is a potent skin irritant it is not toxic or dangerous for skin. In concentrations of 2% to 5%, SLS can cause allergic or sensitizing reactions in lots of people. It is used as a standard in scientific studies to establish irritancy or sensitizing properties of other ingredients (Sources: European Journal of Dermatology, September-October 2001, pages 416–419; American Journal of Contact Dermatitis, March 2001, pages 28–32; and Skin Pharmacology and Applied Skin Physiology, September-October 2000, pages 246–257). Being a skin irritant, however, is not the same as a link to cancer, which is what erroneous warnings on the Internet are falsely claiming about this ingredient!

According to Health Canada, in a press release of February 12, 1999 (www.hc-sc.gc.ca/), “A letter has been circulating the Internet which claims that there is a link between cancer and sodium laureth (or lauryl) sulfate (SLS), an ingredient used in [cosmetics]. Health Canada has looked into the matter and has found no scientific evidence to suggest that SLS causes cancer. It has a history of safe use in Canada. Upon further investigation, it was discovered that this e-mail warning is a hoax. The letter is signed by a person at the University of Pennsylvania Health System and includes a phone number. Health Canada contacted the University of Pennsylvania Health System and found that it is not the author of the sodium laureth sulfate warning and does not endorse any link between SLS and cancer. Health Canada considers SLS safe for use in cosmetics. Therefore, you can continue to use cosmetics containing SLS without worry.� Further, according to the American Cancer Society’s Web site (www.cancer.org), “Contrary to popular rumors on the Internet, Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) do not cause cancer. E-mails have been flying through cyberspace claiming SLS [and SLES] causes cancer … and is proven to cause cancer.... [Yet] A search of recognized medical journals yielded no published articles relating this substance to cancer in humans.� See surfactant.
