Drometrizole Trisiloxane-CAS 155633-54-8
Cosmetic-grade Drometrizole Trisiloxane (DTS) is a high-end silicon-based organic broad-spectrum sunscreen agent, combining benzotriazole UV absorption structure and silicone chain modification technology, which is a star raw material for long-acting waterproof sunscreen in the global cosmetic industry.
Different from traditional single-band sunscreen agents, DTS achieves synchronous coverage of UVA (320-400nm) and UVB (280-320nm) dual bands, realizing true one-step broad-spectrum sun protection, effectively blocking skin sunburn, tanning and deep photoaging damage.
The unique silicon-based molecular structure endows the product with ultra-high intrinsic photostability, no molecular decomposition or efficacy attenuation under long-term continuous strong sunlight irradiation, no need for additional photostabilizers, completely solving the pain points of traditional sunscreen failure and light degradation.
In addition, the silicone chain structure significantly enhances the film-forming adhesion and waterproof and sweatproof performance of the formula, forming a tight, breathable and durable protective film on the skin surface, which is not easy to fall off with sweat and rain, and greatly improves the outdoor lasting sun protection capacity.
The raw material is mild and non-irritating, low-sensitizing, perfectly compatible with silicone oil systems and mainstream sunscreen raw materials, with stable formula performance and natural and refreshing skin feel. It is the core preferred material for developing high waterproof, long-acting, high-stability professional broad-spectrum sunscreen products.
Key Benefits
• Dual-Band Broad-Spectrum Protection: Synchronously covers full UVA and UVB bands, integrates anti-sunburn and anti-photoaging functions, realizes one-stop comprehensive ultraviolet defense, improves SPF and PA values synchronously.
• Top-Level Intrinsic Photostability: Optimized silicon-modified benzotriazole structure, zero photolysis under long-term sun exposure, no efficacy attenuation, no need for stabilizer compounding, lasting stable protection.
• Super Waterproof & Sweatproof Durability: Unique silicone chain film-forming advantage, tight skin adhesion, durable protective film, resistant to sweat and water erosion, suitable for high-intensity outdoor scenarios.
• Silicone Formula Compatibility: Perfectly compatible with all silicone oil phases, solves the compatibility problems of traditional sunscreen agents in silicone-based formulas, stabilizes product texture and improves skin feel.
• Mild Low-Sensitivity & High Safety: Highly purified formula, non-irritating to skin and eyes, no phototoxicity, low sensitization, compliant with global cosmetic sunscreen regulations, suitable for long-term daily use.
• High Temperature & Storage Stability: Excellent thermal stability, no discoloration or deterioration under high-temperature production and summer storage conditions, stable performance and easy for mass production.
Applications
• Outdoor Waterproof Long-Lasting Sunscreen: Core broad-spectrum raw material for sports, seaside and outdoor high-intensity sunscreen, enhance waterproof and sweatproof performance, extend sunscreen holding time for all-day protection.
• Silicone-Based Refreshing Sunscreen Series: Special raw material for high-end silicone sunscreen formulas, optimize transparent and light texture, avoid greasiness and powder floating, and improve product grade.
• High-Power Full-Spectrum Sunscreen: Used in SPF50+ PA++++ professional sunscreen products, synergistically improve full-band defense capability, stabilize protection index and avoid efficacy attenuation.
• Transparent Sunscreen Spray: Suitable for invisible lightweight spray formulas, good fluidity and film-forming property, natural and docile skin feel without white film, suitable for whole-body universal sun protection.
• Anti-Photoaging Isolation Products: Added in high-end sunscreen isolation cream and anti-aging skin care products, resist ultraviolet deep damage, delay skin aging, and realize integrated protection and maintenance.
