我不是專家,
一個叫SqualAne 一個叫 SqualEne,
我今天才發現原來有差別,怪不得 HABA 成條line都係 SqualAne ~
看看wiki 》
Not to be confused with squalene. (連WIKI都提醒吾係SqualEne)
Squalane is a natural hydrocarbon and triterpene derived from a variety of plant and animal sources. It is a component of human sebum. Squalane is a saturated analog of squalene, from which it can also be produced by hydrogenation.
The chemically inert nature of squalane makes it useful in cosmetic applications, where it is used as an emollient and moisturizer.[2] Squalane has low acute toxicity and is not an irritant at concentrations used in cosmetics.[3]
SqualAne 的好處主要都是因為比較溫和,用來保濕是不錯的。
可是再看看
Squalene is a natural organic compound originally obtained for commercial purposes primarily from shark liver oil, though plant sources (primarily vegetable oils) are used as well, including amaranth seed, rice bran, wheat germ, and olives. All plants and animals produce squalene, including humans. Squalene has been proposed to be an important part of the Mediterranean diet as it may be a chemopreventative substance that protects people from cancer.[2][3]
Squalene is a hydrocarbon and a triterpene, and is a natural and vital part of the synthesis of cholesterol, steroid hormones, and vitamin D in the human body.[4] Squalene is used in cosmetics, and more recently as an immunologic adjuvant in vaccines.
Squalene 跟 squalane 都是 hydrocarbon,
可是 Squalene 還有一種叫 triterpene(膽固醇,類固醇激素的合成,維生素D)
可以預防Cancer,還可以防疫~
Squalene oil is the most common fat and antioxidant produced in and on human skin. It is a natural moisturizer.
Squalane is a saturated form of squalene in which the double bonds have been eliminated by hydrogenation. Squalane is less susceptible to oxidation than squalene. Squalane is thus more commonly used than squalene in personal care products, such as moisturizers.
Toxicology studies have determined that in the concentrations used in cosmetics, both squalene and squalane have low acute toxicity, and are not significant human skin irritants or sensitizers.[9]
Squalene除了是人體有的一種油,還是有 抗氧化的!
不過我再網絡上看到些批評Squalene unstable,所以推薦Squalane;
但也不知道是真是假。。。。。。。。。。
