Is BB Micro Silk a Silicone?

Based on the ingredient information, BB Micro Silk is not classified as a silicone. Its INCI name is HDI / Trimethylol Hexyllactone Crosspolymer (and) Silica.

While it provides a soft, smooth, and silk-like feel and is often used in formulations alongside silicones (such as in silicone-based BB creams), its primary components are a crosspolymer and silica, not silicone polymers.

Products like SiliSilk™ 1.5Micron, SiliSilk™ 5H, and SiliSilk™ 5L are examples of ingredients that are silicone powders, with INCI names indicating they are silicone crosspolymers.
