Introducing TC-UV TDSA — The Solution to Modern Formulation Challenges
In today’s era of innovation, every industry is pushed to maximize product performance — including the beauty industry. TC-UV TDSA, or terephthalethylene dicamphorsulfonic acid, is an advanced organic UV filter that provides broad-spectrum protection against both UVA and UVB rays. This filter stands out for its excellent photostability, proven safety, and eco-friendly profile.
The TC-UV TDSA sunscreen innovation meets the demand for formulations that are water-soluble, lightweight on the skin,environmentally and ocean-friendly. Sunscreens containing this ingredient are chemically stable and difficult to degrade, meaning they are not easily absorbed by the human body — making them safe and highly compatible with skin.
Key Benefits of TC-UV TDSA
High Molecular Weight (>500 Da)
Prevents skin penetration and ensures consumer safety. The higher molecular weight, the lower the chance of skin absorption — making it safer. Conversely, a lower molecular weight increases the likelihood of entering the skin and bloodstream, making it less safe.
Optimal UV Protection
With a maximum absorption at 345 nm and a critical wavelength of 373 nm, it provides excellent UVA coverage.
Water-Soluble Formulation
Completely soluble in water, making it ideal for lightweight, transparent, and non-greasy formulations.
Eco and Ocean-Friendly Formulation
Unlike conventional oil-soluble UV filters such as Octocrylene or Benzophenone, which can disrupt marine ecosystems, TC-UV TDSA is biodegradable and safe for marine life — particularly coral reefs.
