In the world of advanced sunscreen formulations, Tinosorb M has become one of the most reliable and effective UV filters available today. Developed by BASF, it stands out as a hybrid organic–inorganic UV filter that offers broad-spectrum protection against both UVA and UVB rays. Unlike traditional filters that only block a specific range of wavelengths, Tinosorb M works across the entire UV spectrum—making it a key ingredient for high-performance, long-lasting sun care products.
At Xiamen Aeco Chemical Industrial Co., Ltd., we specialize in supplying high-purity Tinosorb M for global cosmetic and personal care manufacturers. Our version ensures consistent particle size distribution, excellent dispersion properties, and compliance with international cosmetic regulations, ensuring safety and stability in final formulations.
Tinosorb M (INCI name: Methylene Bis-Benzotriazolyl Tetramethylbutylphenol) acts as a broad-spectrum UV absorber and scatterer. It absorbs short- and long-wave UVA (320–400 nm) and UVB (280–320 nm) radiation while scattering and reflecting the light to prevent deep skin penetration.
Its microfine particle size (typically <200 nm) allows it to remain transparent on the skin—eliminating the white cast that often accompanies traditional mineral filters like zinc oxide or titanium dioxide. Moreover, it is photo-stable, meaning it does not degrade when exposed to sunlight, ensuring long-lasting sun protection and better product performance throughout the day.
The unique hybrid nature of Tinosorb M—combining organic and inorganic characteristics—offers a series of benefits that traditional UV filters cannot match:
Broad-spectrum coverage: Protects against both UVA and UVB rays effectively.
Excellent photostability: Maintains efficiency even under prolonged UV exposure.
Compatibility: Works synergistically with other UV filters such as Avobenzone, Octocrylene, or Titanium Dioxide.
Transparency: Delivers a clear finish without whitening.
Low skin penetration: Safe and suitable for sensitive skin formulations.
These properties make Tinosorb M an essential component in premium sunscreen lines, daily moisturizers with SPF, and even tinted or makeup foundations that include UV protection.

Our Tinosorb M is manufactured under stringent quality control processes, ensuring high purity and consistency batch after batch. It meets EU and Asian cosmetic regulatory standards, making it suitable for global markets.
In formulation testing, Tinosorb M consistently demonstrates outstanding protection performance. It enhances SPF values significantly when combined with other filters, allowing formulators to create lighter, more elegant sunscreen textures without compromising UV defense.
When used in synergy with Tinosorb S or Avobenzone, the result is a formula that remains stable and effective throughout long sun exposure periods. The versatility of Tinosorb M makes it ideal not only for sunscreens but also for daily skincare, anti-aging creams, and BB creams—offering invisible protection for everyday use.
Dispersion Step: Pre-dispersing Tinosorb M in the oil or water phase before emulsification enhances stability and uniform distribution.
Emulsion Type: Works well in both O/W (oil-in-water) and W/O (water-in-oil) emulsions.
Compatibility: It is compatible with silicones, emollients, and most organic filters, improving the sunscreen's overall film-forming ability.
Combination Use: Using Tinosorb M together with micronized titanium dioxide or Tinosorb S achieves optimal protection efficiency and transparency.
These formulation guidelines ensure that Tinosorb M performs effectively in both high-SPF sunscreens and daily wear skincare products.
Reliable Quality: Sourced from certified suppliers, verified through strict internal quality checks.
Global Compliance: Conforms to EU Cosmetic Regulation (EC) No. 1223/2009 and other international standards.
