抗起泡劑、柔潤劑、肌膚防護劑,可作為疏水膜、防水劑。Silicone 類物質,不揮發液體矽,為人工合成材料 - 矽化物,高純度矽靈類幾乎是無毒性的,能給予產品滑柔及絲綢感,並形成薄膜在皮膚上,清爽不黏膩,通常用於輔助著妝或潤絲用品上,以創造質感,依黏稠度不同有許多應用及變化。含矽靈的產品通常只能帶來短暫的立即效果,無法長期維持及吸收,甚至可能會減低其他成份的滲透效率,因此較適合添加於非滲入肌膚型產品配方中。廣被用於乳液、乳霜、防曬製品、粉底產品、止汗產品、護髮產品中。

非揮發性成分,親脂性與親水性接不佳,只覆蓋在角質層,容易清潔或卸妝移去,不會造成堆積的垃圾(取自張麗卿 博客分享)

一直有個疑問,矽靈這個成份到底會不會造成對皮膚的危害?因為這個產份很廣氾的使用,各種說法都不一@@

揮發性高的矽靈其實不會堆積在皮膚毛孔

可是高揮發的矽靈是Cyclomethicone,Dimethicone不是高揮發性的。

不知道是不是有矽靈的產品就應該要卸妝(注意清潔步驟?)

矽靈使用優點
1. 不干擾保養品效果:它不會與保養品其他成份相互作用,影響效益
2. 增加保養品的質感與使用性方便:常見有 Dimethicone 及 Cyclomethicone 兩種。
Dimethicone:分子量大小不同,有不同用途
分子小於 100:常用於噴霧式止汗劑
分子 100~500:則常用於保養品中,讓肌膚感到滑順,彩妝品有水漾波光感。
分子大於 500:則常用於防水性產品。
Cyclomethicone:屬於高揮發性,常用於油性肌膚用保養品及彩妝品中。

A type of silicone, dimethicone is one of the most frequently used emollient ingredients in moisturizers due to its gentleness and effectiveness. Dimethicone is considered a synthetic ingredient, even though it’s derived from natural silicon.

Applied to skin, dimethicone forms a permeable barrier that works to prevent moisture loss and impart a wonderfully silky feel.

Dimethicome is considered safe as used in cosmetic products.

Dimethicone is a silicone-based polymer widely used for its silkiness and conditioning properties.

Dimethicone forms a barrier on the skin’s surface that helps to block water loss while giving skin a silky feel. As an emollient, dimethicone helps to improve skin softness and flexibility by filling in the spaces in the top layer of skin. It is included in skincare products for these moisturizing benefits.

Dimethicone is appropriate for all skin types. It is non-comedogenic, or non-pore clogging. Because of its gentleness and effectiveness, dimethicone is one of the most commonly-used moisturizing ingredients and can be found in many products, including lotions, creams and serums.
