The secret of molecular structure
Trimethylsiloxysilicate (INCI name) has a three-dimensional network structure, and its Si-O bond energy is as high as 452kJ/mol, far exceeding the 348kJ/mol of C-C bond. This structure makes its UV protection efficiency 40% higher than that of traditional organic sunscreens, while avoiding the problem of photodegradation.


Innovative application
When compounded with traditional sunscreens, silicone resin can form a nano-scale three-dimensional protection network:


Refracting UV rays (physical protection)


Fixing chemical sunscreen molecules (preventing photolysis)


Regulating product viscosity (improving spreadability)
A laboratory test showed that the SPF value of sunscreen with 10% silicone resin increased by 28%, and the protection efficiency attenuation rate was reduced to less than 5% after 6 hours.


Environmental breakthrough
The new generation of biodegradable silicone resin uses enzymatic hydrolysis technology, and the decomposition rate in the natural environment is 92% in 180 days, solving the environmental residue problem of traditional silicone materials. In 2023, the EU has approved its use in eco-friendly sunscreen products.
