Cosmetic-Grade Trimethylsiloxysilicate (TMS) Powder, Film Former / Sunscreen Booster

In sunscreen foundation formulations, Trimethylsiloxysilicate serves as a crucial multi-functional additive. It acts not only as a potent film-former but also as a booster and stabilizer for the sunscreen system. It works synergistically with organic UV filters and powder pigments to form a dense, breathable, and hydrophobic flexible protective film on the skin. This film significantly enhances the water and sweat resistance of the formula, preventing the washing away of UV filters and pigments, thereby ensuring lasting SPF efficacy and makeup integrity.

• Boosts Sunscreen Durability: The hydrophobic film effectively reduces the loss of UV filters due to sweating or water immersion, making it a key ingredient for products claiming water resistance.
• Stabilizes Makeup & SPF Protection: Prevents the migration, pooling, or formation of gaps of foundation and sunscreen components on the skin. This ensures uniform and consistent UV protection (minimizing the risk of localized sunburn) and long-lasting wear.
• Improves High-SPF Formula Feel: Mitigates the heavy, greasy feel often associated with high levels of sunscreens and powders. It delivers a smoother, drier application experience and aids in achieving a natural matte finish.
• Enhances Skin Adhesion & Comfort: Makes sunscreen-infused formulas feel lighter and more skin-adherent, reducing the potential for pore-clogging and white cast, thus improving all-day comfort.
