Defoaming agent; Skin conditioning; Emollient; Skin Protecting, it can be used as hydrophobic membrane and water repellent.

Silicone substances, non-volatile liquid silicon, are synthetic materials - silicon compounds, high-purity silicon spirits are almost non-toxic, can give products a smooth and silky feel, and form a film on the skin, refreshing and non-sticky, usually It is used to assist makeup or silk conditioners to create texture. There are many applications and variations depending on the viscosity.

Silicone-containing products usually only bring short-term immediate effects, cannot maintain and absorb for a long time, and may even reduce the penetration efficiency of other ingredients, so it is more suitable for adding non-penetrating skin-type product formulations. Widely used in lotions, creams, sunscreen products, foundation products, antiperspirant products, and hair care products.

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.

Since dimethicone is frequently used, should acne skin pick the ones with this one listed lower on their ingredient lists?

環狀聚二甲基矽氧烷(矽油)(矽油會把毛鱗片之間的空隙填滿,造成滑順的觸感,繼而出現頭髮斷裂、開叉、頭屑、嚴重脫髮。)

長期使用會使毛孔阻塞越洗越油 真的建議不要再使用這個成分了!!!

矽靈能使洗髮產品滑順,形成防護膜、避免頭髮毛燥的功能,類似凡士林,下次洗頭時能完全洗淨。
並不會堵塞毛孔、掉髮、禿頭,更別說資料來源是內容農場。

多看張麗卿、邱品齊等專家的資訊,誤信來源不明的文章。
