Common Name(s): Hexyl methicone,hexyl-modified methicone,short-chain alkyl silicone
DESCRIPTION
What It Does: Provides an ultra-lightweight, silky, fast-spreading feel in skin care and makeup products.
Why It's Used: The hexyl modification on methicone creates a short-chain alkylsilicone with both silicone and alkyl character; provides a slightly more lipophilic feel than standard methicone/dimethicone while remaining very lightweight.
How It Works: Short hexyl (c6) chain on methicone backbone provides mild lipophilicity beyond standard methicone; creates ultra-light, fast-spreading silicone feel; slightly volatile at body temperature.
Typically Found In: Lightweight serums,primers,sunscreens,ultralight skin care
