Silicone 类物质,不挥发液体硅,为人工合成材料 - 硅化物,高纯度硅灵类几乎是无毒性的,能给予产品滑柔及丝绸感,并形成薄膜在皮肤上,清爽不黏腻,通常用于辅助着妆或润丝用品上,以创造质感,依黏稠度不同有许多应用及变化。
含硅灵的产品通常只能带来短暂的立即效果,无法长期维持及吸收,甚至可能会减低其他成份的渗透效率,因此较适合添加于非渗入肌肤型产品配方中。广被用于乳液、乳霜、防晒制品、粉底产品、止汗产品、护髮产品中。

非挥发性成分,亲脂性与亲水性接不佳,只覆盖在角质层,容易清洁或卸妆移去,不会造成堆积的垃圾(取自张丽卿 博客分享)
挥发性高的硅灵其实不会堆积在皮肤毛孔
可是高挥发的硅灵是Cyclomethicone,Dimethicone不是高挥发性的。
不知道是不是有硅灵的产品就应该要卸妆(注意清洁步骤?)
硅灵使用优点
1. 不干扰保养品效果:它不会与保养品其他成份相互作用,影响效益
2. 增加保养品的质感与使用性方便:常见有 Dimethicone 及 Cyclomethicone 两种。
Dimethicone:分子量大小不同,有不同用途
分子小于 100:常用于喷雾式止汗剂
分子 100~500:则常用于保养品中,让肌肤感到滑顺,彩妆品有水漾波光感。
分子大于 500:则常用于防水性产品。
Cyclomethicone:属于高挥发性,常用于油性肌肤用保养品及彩妆品中。

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?
grffff: skincare products should not contain this ingredient, but make up is okay
环状聚二甲基硅氧烷(硅油)(硅油会把毛鳞片之间的空隙填满,造成滑顺的触感,继而出现头髮断裂、开叉、头屑、严重脱髮。)
长期使用会使毛孔阻塞越洗越油 真的建议不要再使用这个成分了!!!

硅灵能使洗髮产品滑顺,形成防护膜、避免头髮毛燥的功能,类似凡士林,下次洗头时能完全洗净。
并不会堵塞毛孔、掉髮、秃头,更别说资料来源是内容农场。
多看张丽卿、邱品齐等专家的资讯,误信来源不明的文章。
