我是沒特別去研究啦!
不過嬰兒油應該是礦物油(Mineral Oil)
而綿羊油(Lanolin Oil)則是動物性油脂
以下我轉貼Paula Begoun網站上的ingredient Dictionary
希望有幫助
Mineral oil: Clear, odorless oil derived from petroleum that is widely used in cosmetics because it rarely causes allergic reactions and can`t become a solid and clog pores. Despite mineral oil`s association with petroleum and the hype that it is bad for skin, keep in mind that petroleum is a natural ingredient derived from the earth and that once it becomes mineral oil, it has no resemblance to the original petroleum. Cosmetics-grade mineral oil and petrolatum are considered the safest, most nonirritating moisturizing ingredients ever found (Sources: Cosmetics & Toiletries, January 2001, page 79; and Cosmetic Dermatology, September 2000, pages 44?6). Yes, they can keep air off the skin to some extent, but that`s what a good antioxidant is supposed to do; they don`t suffocate skin! Moreover, mineral oil and petrolatum are known to be efficacious in wound healing, and are also considered to be among the most effective moisturizing ingredients available (Source: Cosmetics & Toiletries, February 1998, pages 33?0).
