Glyceryl Stearate
中文譯名中的“硬脂酸酸甘油酯”是不是多了一個字
應該是“硬脂酸甘油酯”吧?
謝謝。

原諒我對化學反應不是十分了解,我想請問如果使用的乳液中含有Glyceryl Stearate ,塗抹于面部后它會很容易自行乳化成Glyceryl Stearate SE從而達到一個很高的面皰發生性嗎?需要什麼條件才會發生如上情況?

據報導,濃度高達100%的硬脂酸甘油酯和硬脂酸甘油酯/ SE對兔皮膚有輕微刺激性或無刺激性。
Single and repeated insult patch tests used to evaluate human skin irritation and sensitization potential of up to 20% glyceryl
stearate showed the ingredient to be non-sensitizing and non-irritating
In primary eye irritation studies, glyceryl stearate and glyceryl stearate/SE at concentrations up to 100% were mildly
irritating or non-irritating when instilled in the eyes of rabbits.
In clinical testing, 5% glyceryl stearate was not
irritating.

【Glyceryl Stearate】

Rating: GOOD
Benefits: Hydration
Categories: Emollient, Emulsifier, Cleansing Agent

Glyceryl stearate is a mixture of portions of glycerin and stearic acid. While it’s found naturally in the human body and can be animal-derived, most glyceryl stearate used in cosmetics is plant-derived (such as from olive oil or coconut) or produced synthetically. In its raw form it is a white or cream-colored wax-like solid.

Glyceryl stearate functions as an emollient, surfactant, and emulsifier in skin care products. Its emulsifying properties are highly versatile, making it a valuable and gentle addition to several types of emulsions, such as oil-in-water or water-in-oil, where it helps support the benefits of skin-replenishing ingredients such as ceramides and fatty acids. Its moisturizing properties help skin look and feel softer and smoother. It also forms a barrier on skin, helping prevent water loss. In addition, glyceryl stearate is used as a food additive.

The Cosmetics Ingredient Review Panel has found glyceryl stearate to be safe within its typical usage levels of 1–10%. Studies have also shown it to be non-sensitizing, and plant-derived glyceryl stearate is allowed for use in cosmetics and personal care products marketed in Europe.
