回覆上述(網友訪客與beauty00729): 邱品齊醫師對於 SLES &SLS 兩種成分的介紹與釋疑 :http://tw.myblog.yahoo.com/skindocchiu-cosmeticfact/article?mid=6088&prev=6907&next=5907&l=f&fid=28 .

擷取部分重點:


於是目前結論是無論是SLS或是SLES本身都不是致癌性成份(Carcinogen)

如果要以最嚴格挑剔的論點來看的話

應該說SLS高濃度長期使用可能會有促癌的可能性

而製造SLES時所產生的1,4-dioxane副產物有可能會有致癌的可能性

但這兩種狀況以目前一般的使用情形來說幾乎是可以不需擔心的

表面活性剂:【月桂醇聚醚硫酸酯钠】
英文 名称: Sodium lauryl polyoxyethylene ether sulfate AES
用 途: 去污剂 起泡剂 乳化剂

娇艳的好处:泡泡丰富,使用后面部立刻马上分分钟细滑,哇塞!!(⊙o⊙)哦

忧伤的坏处:
皮肤方面,石化型表面活性剂,假滑现象明显,分分钟的细腻不过一场梦幻泡影,如雾亦如电%>_。德标3%安全,国标似乎是5%。含量在标准以上后,破坏肌肤油脂质膜,蛋白质以及使胶原蛋白流失,皮肤越用越娇气敏感,造成松垮老化 敏感 暗黄。因为其又是螨虫喜爱的食物,容易造成螨虫滋生,刺激肌肤形成粉刺 痘痘 酒糟鼻等

身体方面,通过皮肤吸收抵达肝脏后难以排出,损伤肝脏,面部表现为面色暗黄,纯色暗灰
进入生殖系统后,对男性降低精子活性,对女性容易造成宫颈或者乳腺癌。但发病率较低

对后代方面。其潜伏在人体,对成人危害发病率较低,进入胚胎后可引起婴儿阴道闭合 不孕不育 睾丸发育不良等症状。 马普尚在研究的项目 结论待定

现在这么多不孕不育的,不知道跟这些新型化合物是否有关!!可怕哇。
当然,如果严格控制使用剂量,危害很低。 不要唯成分里论啊,不要草木皆兵啊

对生殖系统的影响相比外源性激素类添加剂要轻微许多,但仍然不容忽视

sodium laureth sulfate is not the same as sodium lauryl sulfate
Heres a post from paulas choice:

Used primarily as a detergent cleansing agent. Can be derived from coconut. It’s considered gentle and effective as typically used in cosmetics products (typically facial or body cleansers and shampoos). Despite the name similarity, sodium laureth sulfate is NOT the same as sodium lauryl sulfate. The former is a milder cleansing agent due to a higher amount and different chemical structure of the fatty alcohols required to manufacture this cleansing agent. The safety of sodium laureth sulfate has been reviewed by numerous industry experts and deemed safe as used.

SLES is prepared by ethoxylation of dodecyl alcohol, which is produced industrially from palm kernel oil or coconut oil. The resulting ethoxylate is converted to a half ester of sulfuric acid, which is neutralized by conversion to the sodium salt.[1] The related surfactant sodium lauryl sulfate (also known as sodium dodecyl sulfate or SDS) is produced similarly, but without the ethoxylation step. SLS and ammonium lauryl sulfate (ALS) are commonly used alternatives to SLES in consumer products.[1]

SLES是通過十二烷醇的乙氧基化製備的,十二烷醇是由棕櫚仁油或椰子油工業生產的。 生成的乙氧基化物被轉化為硫酸的半酯,通過轉化為鈉鹽而被中和。[1] 類似地生產相關的表面活性劑月桂基硫酸鈉(也稱為十二烷基硫酸鈉或SDS),但是沒有乙氧基化步驟。 SLS和月桂基硫酸銨(ALS)是消費產品中SLES的常用替代品。[1]

我只要洗,含有 sls、sles、als、 Cocoamidopropyl Betaine 的洗髮精 都會過敏(頭皮癢 頭皮皮膚過敏發炎 頭皮屑),而且有Cocoamidopropyl Betaine的洗髮精 洗了好像都會有銀屑(有時頭髮乾後 頭皮感覺有些東西 屑之類),

特別是那種洗髮精sls、Cocoamidopropyl Betaine 洗了,沒多久 頭皮會癢 皮膚過敏發炎,有大大 能介紹 不會過敏的洗髮精嗎?

有些洗髮精不知什麼原因 什麼成份過敏(或著有毒的成份),會造成眼睛 很痛 連帶頭也跟著痛,而且痛到 睡覺 根本睡不著。

SLS,可透過膠束Micelle技術或配方中添加甘油、b5、抗氧化劑、水解蛋白、潤膚劑等減少刺激,若是相當敏感者仍建議避免

可以選擇氨基酸系的洗髮精,可是洗感應該不會很好,但至少比較不傷皮膚,有些人是因為本身有脂漏性皮膚炎的狀況,再加上清潔劑影響導致不斷反覆發炎,建議有皮膚問題建議可以就醫,過敏跟眼睛會癢都挺正常的,洗劑每個人使用狀況都不太一樣

For people with sensitive skin, sulfates may also clog pores and cause acne.
Many products have a lower concentration of SLS or SLES in their formulation. But the longer the products stay in contact with your skin or eyes, the higher the risk of irritation. Rinsing off the product immediately after use reduces risk of irritation.

For cleaning skin and hair: Opt for solid and oil-based soaps and shampoos rather than liquid. Some products to consider include African black soap and body cleansing oils. Lather and foam aren’t crucial to cleaning skin or hair —sulfate-free products can also do the job.
