這個成份加在乳液裡面不知道會不會長痘痘。不知道為什麼極潤系列會想添加此成份...
""建議小心使用，與脂肪酸作用會產生皂化反應。""--請問有人知道/可以舉例例如哪些為 脂肪酸 ? tks a lot.//
我用過這牌的眼線液 畫完眼睛會紅腫 痛到不行
建議有更多有知識份子在這 多多解說一些化學知識
在面膜有這成份會導致敏感及出粉刺暗瘡嗎
用過 base forumla 的玫瑰凝膠面膜, 但好似沒引起出暗瘡丫
脂肪酸(Fatty acid)
十四酸／肉豆蔻酸(Myristic acid)
十二酸／月桂酸(Lauric acid)
十六酸／棕榈酸(Palmitic acid)
十八酸／硬脂酸(Stearic acid)
脂肪經脂肪酶分解成脂肪酸和甘油
我用的是AA网芦荟海藻眼胶..长期接触皮肤不知道有什么后果
有人用過寶藝的保濕冷敷劑嗎?我聽很多人說好用,所以也想買來用用看,可是也有這成份....會敏感或長痘痘粉刺嗎?
百雀羚和相宜本草基本上都有三乙醇胺啊。。。
很擔心啊 新買了一罐蝦紅素精華素 也有這個成份 之前導致紅點點的玫瑰凍膜也有 不知道會怎麼樣(淚
三乙醇胺的潛在毒性
三乙醇胺是一種酸鹼調節劑，主要用在清潔產品上，以調節產品對臉部的刺激性，所以潔臉品或沐浴露都頗常見。
但當用在保養品時，卻另一回事了，因它有著一令人憂慮的副作用。
本文立論源於「美國國立衛生研究院(National Institutes of Health)」，於２００４年發表的研究報告，編號「NTP TR-518」
這研究是科學家找來一些實驗用的老鼠，在牠們的皮膚塗上三乙醇胺，每週五天並為期兩年，之後再對照同期，沒在皮膚塗上三乙醇胺的老鼠，當檢查牠們的生理變化時，發現以下的現象：
塗了三乙醇胺的雄性老鼠，牠肝臟的血管肉瘤出現稍微的增大；而雌鼠肝臟腫瘤更是明顥地增大。
科學家分析了數據後，對此研究得出以下結論(英語原文)：
We conclude that triethanolamine caused liver tumors in female mice and may have caused a slight increase in hemangiosarcomas of the liver in male mice.
中譯：我們斷定三乙醇胺導至雌鼠的肝臟腫瘤，以及令雄鼠的肝臟血管血瘤稍微增大。
三乙醇胺：三乙醇胺是一种有机化合物，可以调节皮肤酸碱平衡，是一种已知的会对人体免疫和呼吸系统造成破坏的毒剂，皮肤长期或反复接触会导致发炎、红肿、疼痛，眼睛接触的话会造成严重刺伤、发炎以及角膜损伤等。虽然三乙醇胺在化妆品中含量较少，但却容易与脂肪酸作用产生皂化反应(即油脂的水解)，所以要尽量避免长期接触。

内分泌干扰素
三乙醇胺應用於化妝品，九成以上主要功能為酸鹼調節，剩下一成則用於液體皂，用量的確也是不多，但若有使用這對此產品敏感度較高仍建議避免使用；至於致粉刺性，此原料的確刺激性較高，但應用於配方中致痘或致粉刺性並不光是此原料導致，有些為配方設計問題，甚至有部分原因為營養原料含量過高所致，因此看到含此原料之化妝品毋須過度恐慌
三乙醇胺(Triethanolamine，TEA)是很多化妝品的添加物，例如
防曬霜、保濕霜、粉底液和染髮劑。作為表面活性劑和調節pH的化學
物質。三乙醇胺和二乙醇胺與硝酸鹽結合會產生亞硝胺，亞硝胺被世
界衛生組織國際癌症研究所(IARC)定義為可能的人類致癌物(2A)。
蘭之的晚安面膜就是加了這個導致一堆人用了致痘致粉刺，尤其是敏感油肌要特別注意。
這個成分的我用了都會致粉刺orz
萊雅的底妝產品跟保養品以前各用過一款都含三乙醇胺
感覺萊雅東西常有三乙醇胺
所以沒甚麼好感
特別筆記一下
http://www.thedermreview.com/triethanolamine/
Triethanolamine can most often be found in cosmetics such as eye shadow, mascara, eyeliner, fragrance, foundation and concealer. Sometimes, it is also added to hair care products such as hair dyes, wave sets. Triethanolamine is also common in shaving creams and gels, as well as sunscreen formulas. Its main use is to balance the overall pH of a product, but it also works as an emulsifier that helps products retain a more homogenous appearance and to spread creams more evenly over the skin. This is especially important for cosmetic products so that they do not lump or cake on the skin.
In most cases, products containing triethanolamine are not meant to have prolonged contact with the skin and should be washed away daily. Keep this in mind if you are going camping or on road trips, where you may not have access to adequate facilities to cleanse your skin. While the FDA has approved triethanolamine as being safe for use, the organization also recommends that any product which contains this chemical should have no greater than a 5% concentration in order for it to remain safe for use. Despite its many uses, triethanolamine is moderately dangerous to the skin if it is applied on a long-term basis. If you have any concerns about the dangers of triethanolamine, there are a number of ways to lower your risk of exposure.
STRONGLY ALKALINE substance- used as a pH adjuster.
Triethanolamine, or TEA is a viscous organic compound that is both a tertiary amine and a triol.
A triol is a molecule with three alcohol groups.
三乙醇胺或TEA是粘性有機化合物，既是叔胺又是三醇。
三醇是具有三個醇基的分子。
Triethanolamine is produced from the reaction of ethylene oxide with aqueous ammonia, also produced are ethanolamine and diethanolamine.
The ratio of the products can be controlled by changing the stoichiometry of the reactants.
三乙醇胺是由環氧乙烷與氨水反應生成的，還生成了乙醇胺和二乙醇胺。
產物的比例可以通過改變反應物的化學計量來控制。
Triethanolamine is used primarily in making surfactants, such as for emulsifier.
三乙醇胺主要用於製造表面活性劑，例如乳化劑。
The triethanolamine neutralizes fatty acids, adjusts and buffers the pH, and solubilizes oils and other ingredients that are not completely soluble in water.
三乙醇胺可中和脂肪酸，調節和緩衝pH值，並溶解不完全溶於水的油和其他成分。
Some common products in which triethanolamine is found are sunscreen lotions, liquid laundry detergents, dishwashing liquids, general cleaners, hand sanitizers, polishes, metalworking fluids, paints, shaving cream and printing inks.
發現有三乙醇胺的一些常見產品是防曬乳液，液體洗滌劑，洗碗液，普通清潔劑，洗手液，拋光劑，金屬加工液，油漆，剃須膏和印刷油墨。
