Description

FSS SilDerm® SQ is a modernized version of Polymethylsilsesquioxane (PMSQ)—a silicone compound known for its unique 3D ladder-type polymer structure. The formula [CH₃SiO₃/₂]ₙ[CH₃Si(OH)O₃/₂]ₘ showcases how the ingredient forms a network of siloxane bonds, populated by methyl and hydroxyl groups. By adjusting the ratio of these functional groups, the surface activity can be fine-tuned to meet specific formulation needs.

Thanks to improved production methods, SilDerm® SQ avoids contamination issues typically associated with traditional PMSQ production, such as draggy textures and unwanted alcohol byproducts like methanol. The result is a refined, efficient silicone-based powder suitable for improving aesthetics and stability across various cosmetic products.

In emulsions, SilDerm® SQ acts as a partitioning agent at the oil-water interface, promoting enhanced emulsion stability. In color cosmetics, it diffuses light, improves spreadability, preserves translucency, and helps achieve a matte finish without compromising smoothness. As such, it’s a versatile solution for formulators looking to overcome sensory or performance limitations in existing products.

Made Of:

A soothing botanical blend containing Hyacinthus orientalis (Hyacinth) Flower Extract in a base of water and propylene glycol, preserved with Leuconostoc/Radish Root Ferment Filtrate.

Why It’s Perfect for You:

FSS SilDerm® SQ is ideal for advanced skin care, makeup, and emulsified products seeking to improve light management, stability, and formulation elegance—making it a must-have for high-performance formulations.

Suggested Applications

Foundations & BB creams, emulsion-based skincare, pigmented cosmetics, primers and mattifying serums.
