Core Ingredient for Long-Lasting Water/Sweat-Resistant Sunscreen: Trimethylsiloxysilicate Film Former

BT-6803P is an advanced MQ silicone resin produced via an optimized, solvent-free manufacturing process. This exclusive process results in a product with an improved dissolution rate in cosmetic oils, ensuring easier and faster incorporation into your sunscreen formulations during production, thereby enhancing manufacturing efficiency.

In sunscreen products, BT-6803P performs three critical functions:

• SPF/PA Performance Booster: It acts as a film-forming powder that creates a uniform matrix on the skin, optimizing the distribution and network of UV filters (both chemical and physical). This leads to more efficient UV light attenuation, allowing for a measurable increase in SPF and UVA protection values without raising filter concentrations.
• Water & Sweat Resistance Enhancer: The durable, hydrophobic silicone film formed by BT-6803P effectively "locks" sunscreen actives in place on the skin. This provides excellent resistance to wash-off from water, swimming, and perspiration, helping formulations meet and maintain stringent 40-minute or 80-minute water-resistant claims.
• Texture & Wear Improver: It imparts a soft, velvety, and matte finish, reducing the greasy or sticky feel often associated with high-SPF and water-resistant products. This improves ultimate consumer comfort, wearability, and premium product perception.

• Proven Performance: Enhances key sunscreen metrics: higher SPF efficiency, stronger water resistance, and superior skin feel.
• Manufacturing-Friendly: Solvent-free process ensures purity, while the optimized dissolution rate saves time and energy in production.
• Formula Versatility: Excellent compatibility with a wide range of UV filters and cosmetic oils, suitable for various emulsion types (O/W, W/O).
• Market-Driven: Enables the creation of modern sunscreens that meet growing demand for long-lasting, sensorially elegant, and high-fidelity protection.
