The idea of combining organic and inorganic filters in a single formula is not new. Indeed, these two types of ingredients have complementary benefits. Organic UV filters absorb and convert UV rays into heat energy, offering smooth application and reduced white cast. Conversely, inorganic sunscreens reflect UV rays from the skin, providing strong UV protection but often leaving a white cast. Hybrid sunscreens combine these mechanisms to maximize benefits, though technical challenges such as ingredient aggregation have hindered achieving optimal performance.
Encapsulation of mineral filters
According to Kolmar Korea, their new technology, dubbed "UV-DUO PLUS", solves this technical challenge by encapsulating inorganic particles with organic sunscreen components.
“By coating inorganic sunscreen particles with organic components, this technology ensures even dispersion within formulations, eliminating aggregation and enhancing UV protection efficacy,” claimed the supplier.
According to Kolmar Korea, the "UV-DUO PLUS" technology also efficiently targets long-wavelength UVA rays, which are a key driver of the skin’s photoaging.
Clinical tests on human skin demonstrated that sun care products incorporating this technology improved long-wavelength UV blocking efficiency by 24.8% in the 400 nm range compared to conventional sunscreens.
Sunscreens developed using this patented technology achieve SPF 50+ PA++++ protection. Kolmar Korea, boasts over 70 patents related to UV protection.
The company recently strengthened its footprint in the USA through the building of a second U.S. plant located in Pennsylvania and slated to begin operations in the first half of this year. This new production will boost Kolmar’s annual production capacity in North America from 180 million to 300 million units.
