呃....這個是防腐劑 不是保濕喔

也具保濕功能

可在無防腐劑保存系統中使用
水中溶解度:~0.1%
以下是我讀完放在CIR網站上的相關文件之後歸納的結果
動物實驗結果顯示乙基己基甘油沒有刺激性也不是致敏物,但在動物的毒性測試中發現吸入毒性,實驗條件為將老鼠暴露在霧化的乙基己基甘油中4小時,再觀察14天,結果顯示LC50為3.07 mg/L,低到中度毒性。
人體測試的部分在0.4%、0.5%以及1%濃度下進行皮膚測試後結論為本物質沒有刺激性與致敏性。
有案例指出有患者在使用含有5%乙基己基甘油的產品後過敏或是皮膚發炎,但在其他受試者身上均沒有發生此現象(個人認為可能是患者對本物質過敏)。未稀釋的乙基己基甘油具有強烈刺激性,但濃度5%的乙基己基甘油刺激性溫和,另外本物質也無光致敏性與光毒性
由於乙基己基甘油(最多2%)可用於可噴塗的化妝品中,專家討論了偶然吸入暴露的問題。專家指出,在化妝品氣溶膠中產生的95%至99%的液滴顆粒不會被吸入任何可感知的量。再加上呼吸區的實際暴露量和使用成分的濃度,這些信息表明偶然吸入不會是可能導致局部呼吸或全身毒性影響的重要接觸途徑。

Pale to colorless liquid as a raw material
Ethylhexylglycerin Description
Ethylhexylglycerin is a synthetic skin-softening agent. Ethylhexylglycerin can also be used as a preservative and carrier/suspending agent that boosts the efficacy of other preservatives such as phenoxyethanol. It has been shown to have mild humectant properties leading to improved skin hydration without a sticky feel.

Ethylhexylglycerin is also popular in deodorant formulas where it has an inhibiting effect on odor-causing bacteria. Antibacterial action is also where it earns its keep as a preservative, but since it isn’t effective against other type of pathogens, it would always be used with more broad-spectrum preservatives.

As a raw material, ethylhexylglycerin is a pale to colorless liquid. It is formed by a condensation reaction between 2-ethyhexanol (an oil-like ingredient) and glycerin.

In 2013, the Cosmetic Ingredient Review Expert Panel deemed ethylhexylglycerin as safe used in up to 8% concentration in rinse-off products and up to 2% in leave-on formulas. Studies regarding sensitization patch tests of 5% ethylhexylglycerin show that reactions to this ingredient are very rare and their occurrence in a broad population is considered low risk.
