我不懂為何台灣維基寫用古柯葉,明明就是椰子油起泡,不含椰子油是怎回事?查證國外wiki得到以下說明
椰油酰胺丙基甜菜鹼(CAPB)是從椰子油和二甲基氨基丙胺衍生的有機化合物 。 [1],它是一種兩性離子 ,包括一個季銨陽離子和羧酸鹽 。 CAPB可為粘稠的淺黃色溶液,作為表面活性劑 ,在個人護理產品中使用。 反映了該分子的主要部分, 月桂酸基,來自椰子油的名稱。 已經大幅取代椰油酰胺DEA 。

椰油酰胺丙基甜菜碱过敏反应
有些人在使用含有CAPB的产品时会有过敏反应。2004年,美国接触性皮炎协会宣布CAPB为“年度过敏原”。
从那以后,2012年的一项科学综述研究发现,导致过敏反应的不是CAPB本身,而是制造过程中产生的两种杂质。
这两种刺激物是氨基酰胺(AA)和3-二甲基氨基丙胺(DMAPA)。在多项研究中,当人们接触不含这两种杂质的CAPB时,他们没有过敏反应。已纯化的高等级CAPB不含AA和DMAPA,不会引起过敏反应。

Translating the comment from user ftbase:


“Some people have allergic reactions when using products containing CAPB. In 2004, the American Contact Dermatitis Association declared CAPB as the "Allergen of the Year".
Since then, a scientific review study in 2012 found that it is not the CAPB itself that caused the allergic reaction, but two impurities generated during the manufacturing process.
The two stimuli are aminoamide (AA) and 3-dimethylaminopropylamine (DMAPA). In multiple studies, when people were exposed to CAPB that did not contain these two impurities, they had no allergic reactions. The purified high-grade CAPB does not contain AA and DMAPA and does not cause allergic reactions.”

為何我只要洗,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,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。

I've discovered I'm allergic to this after using multiple shampoos with this ingredient. I get itchy red bumps all other my forehead and hairline but when I stop using the shampoo they go away within a few days (so it's not acne. Also no whiteheads form). I've taken long periods of time in between trying shampoos. I was using one shampoo for 6 months that my hairdresser recommended. Then he suggested I switch it up due to weather changes. I got the bumps. Sure enough it had this ingredient. Switched back to my old shampoo, which doesn't contain it, and they went away.

椰油醯胺丙基甜菜鹼(Cocamidopropyl betaine, CAPB),又稱為椰子油起泡劑,是一種介面活性劑,於1967年上市就開始添加在嬰幼兒的清潔產品中,尤其是主打不流淚配方(No tear detergent)的產品,但之後發現此成分會造成過敏性、接觸性皮膚炎,於2004年此成分更被票選為年度過敏原,異位性皮膚炎患者很容易對此物質產生過敏反應,因此,異膚患者盡量不要用含有此成分的清潔產品。

界面活性劑是洗面乳主要的清潔成分,有清潔、去除皮脂污穢的效果。市面上常見強力陰離子界面活性劑SLS(十二烷基硫酸鈉 Sodium Lauryl Sulfate)、SLES(十二烷基聚氧乙醚硫酸鈉 Sodium Laureth Sulfate),洗淨力強,較為刺激,未必人人適用。雖然洗面奶配方中通常會加入其他成分來降低刺激性,但不建議敏感肌使用。

敏感肌、乾燥肌膚想要溫和清潔,可以選擇氨基酸清潔成分,例如椰油醯胺丙基甜菜堿(Cocamidopropyl Betaine)、月桂醯谷氨酸鈉(sodium Lauroyl Glutamate)與椰油醯基麩氨酸三乙醇胺鹽(TEA Cocoyl Glutamate) 。

另外一類界面活性劑,透過動物或植物油脂與強鹼(例如氫氧化鈉sodium hydroxide或氫氧化鉀potassium hydroxide)結合,酸鹼值通常會偏高。洗面產品清潔力、去油脂和除污能力上表現突出,但可能會讓肌膚感覺較為乾燥和繃緊。為了平衡這一效果,製造商通常會添加甘油(glycerin)或其他護膚成分來滋潤肌膚。

想要辨別產品是否含有這種皂化方法製成的物質,可以查看成分列表是否包含脂肪酸,如椰油醯羥乙磺酸鈉(Sodium Cocoyl Isethionate)、肉豆蔻酸(myristic acid)、月桂酸(lauric acid)、棕櫚酸 (Palmitic acid)、硬脂酸(stearic acid)等,以及是否含有強鹼如氫氧化鉀。這些潔面產品通常更適合中性或油性肌膚。
