最重要的一点是,环状硅油,特别是环戊硅氧烷(D5)和环丁硅氧烷(D4,用在化妆品行业中较少),可能会对母乳的产生有影响,有可能会想起婴儿的一些健康问题。至于有多大的严重性,目前还没有确切的证据,并且有一些相关争论在里面。目前加拿大政府已将环戊硅氧烷列为毒性化学成分之一,要求使用这个成分的化妆品公司去申报安全性及用量以便 更好的监管。

硅能为肌肤或毛髮创造丝滑质感,也会在肌肤上形成一层如塑胶般的薄膜,进而瓦解肌肤释放毒素的能力,并使刺激物质阻塞肌肤及毛孔,此外,硅是属于生物无法分解的成分。一般标籤可能会将硅列为:环戊硅氧烷 (cyclopentasiloxane)、硅灵 (dimethicone) dimethicone copolyol.与二甲基硅氧烷共聚物 (dimethicone copolyol)

邱品齐医师他在留言版回应说奇时保养品&洗髮精的硅灵都是不会阻塞毛孔的
硅灵在洗髮精不建议是因为它带来的柔顺感会让人误会,以为髮质很好
而忽略真正的护髮,同时也因为硅灵包覆的特性让后续护髮吃不进去

而硅灵在保养品可能导致部分成分进不去(挥发性硅灵不会)
但也没有阻塞毛孔的风险
且硅灵的密封性有很好的锁水保湿效果
可以发现肌研浓极润.水之印弹力霜都有加,且成分很前面

所以我对硅灵的评价很中性,不好不坏
但我洗髮精不会挑有硅灵的
润髮没关系,护髮尽量不要
保养品尽量不要(有点难度),挥发性硅灵就没差,像雅顿胶囊
化妆品有硅灵反而很喜欢

环戊硅氧烷这个成分的作用是营造一种不油腻好吸收的假象,如果看到他排前的位置,用的时候不会要被好吸收的假象蒙蔽。

"Recently many ingredients have been restricted in cosmetic products, among others: Cyclopentasiloxane (D5) and Cyclotetrasiloxane (D4). Both of them are silicones, and they are used to protect the skin and to retain moisture."
"Cyclopentasiloxane (D5) can also be harmful to the environment."
"What do the Manufacturers need to do?

Make sure that the raw materials supplier provides you with Cyclopentasiloxane (D5) with the highest purity (99%) and that it does not contain Cyclotetrasiloxane (D4)
As a precautionary measure – plan to reformulate rinse-off cosmetic products with Cyclopentasiloxane by decreasing the amount until up to 0,1%, or by replacing it with another type of silicone"
