In the evolving landscape of dermatological science and sun protection, CAS 103597-45-1, chemically known as Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (and commercially recognized as Tinosorb S), stands as the "gold standard" of broad-spectrum UV filters. Unlike traditional chemical sunscreens that often degrade under UV exposure or provide limited coverage, CAS 103597-45-1 offers unparalleled photostability and high-absorption efficiency across both UVA and UVB spectrums.
As a premier CAS 103597-45-1 factory and supplier, Aogebio LLC leverages advanced molecular synthesis to provide high-purity grades that meet the rigorous demands of global skincare brands. This white paper explores why this specific raw material is indispensable for modern SPF formulations and how our specialized manufacturing processes in China provide a competitive edge in quality and scale.

The global market for UV filters is projected to grow significantly as consumer awareness regarding skin cancer and premature aging increases. CAS 103597-45-1 is particularly favored in the EU, Asia, and Latin America due to its oil-soluble nature and synergy with other filters like Avobenzone, which it helps stabilize.
Industry trends are moving away from unstable filters. CAS 103597-45-1 does not significantly degrade even under intense solar radiation, making it an essential ingredient for "long-wear" and "high-protection" (SPF 50+) sunscreens that consumers trust for outdoor activities.
With tightening regulations on "reef-safe" ingredients, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine is increasingly scrutinized and often preferred over older filters like Oxybenzone or Octinoxate, providing a safer profile for both the user and the environment.
Founded in 2013 and headquartered in the prestigious high-tech zone of Xi'an, Xi'an Aoge Biotech Co., Ltd., along with its subsidiaries Xi'an Imaherb Biotech Co., Ltd. and Xi'an Nahanutri Biotech Co., Ltd., has established itself as a leading force in the cosmetics raw materials industry.
Our expansive cooperative factory, spanning 1,000 mu (approximately 165 acres), is equipped with state-of-the-art extraction and synthesis technology. This advanced infrastructure allows us to manufacture a wide array of premium cosmetic raw materials, including natural plant extracts and high-end synthetic ingredients like CAS 103597-45-1.
Located in Xi'an, we benefit from China's robust chemical supply chain. We source raw precursors locally, reducing logistics costs and ensuring a stable supply even during global market fluctuations.
Our factory utilizes multi-stage purified crystallization techniques. This ensures that our CAS 103597-45-1 has minimal impurities, resulting in a cleaner scent and better color stability in finished cosmetic emulsions.
Operating a 165-acre facility allows us to offer bulk pricing that is highly competitive on the global market without compromising the E-E-A-T standards required by pharmaceutical-grade cosmetic manufacturers.
Due to its broad-spectrum coverage, CAS 103597-45-1 is the primary filter used in SPF 50+ formulations. It provides a non-greasy feel compared to physical filters like Zinc Oxide, making it ideal for the Asian and European "light-feel" market.
UVA is the main culprit for photo-aging. Integrating CAS 103597-45-1 into daily moisturizers ensures comprehensive protection against collagen breakdown, which is a major selling point for high-end skincare brands.
As an oil-soluble filter, it integrates seamlessly into water-in-oil (W/O) emulsions, ensuring the product stays on the skin during perspiration or swimming, providing durable protection for athletes.
Its high compatibility with pigments and other cosmetic ingredients allows manufacturers to create multi-functional BB creams that offer high UV protection without compromising the texture or coverage of the makeup.
We are seeing an increased demand from North American "clean beauty" brands looking for EU-approved filters that provide higher efficacy than local US-standard filters. By sourcing our Custom CAS 103597-45-1, international firms can formulate products that meet the highest global safety and performance benchmarks.
Our commitment to excellence is backed by rigorous scientific testing. We don't just supply; we guarantee performance.
Our in-house lab uses advanced instruments like UPLC, HPLC, GC-MS, and ICP-MS for quality control, ensuring raw materials meet strict international standards. Every batch of CAS 103597-45-1 undergoes:
