Common Name(s): Lauryl trimethicone,c12-modified trimethicone,alkyl trimethicone
DESCRIPTION
What It Does: Provides lightweight silicone conditioning with enhanced compatibility with natural oils.
Why It's Used: Trimethicone modified with c12 lauryl group bridges the polarity gap between non-polar dimethicone and organic oils.
How It Works: Trimethicone base provides lightweight silicone feel; c12 lauryl modification provides intermediate lipophilicity enabling better compatibility with organic oils.
Typically Found In: Hybrid silicone-oil formulas,lightweight skin care,specialty silicone systems
