Hi, how are you?
In this issue, we’re excited to introduce a new lineup of silica capsule products – SUNSIL-AB, SUNSIL-EHT, SUNSIL-DHHB, and SUNSIL-BLP – following the launch of SUNSIL-S last April. These innovative silica capsules allow traditionally oil-phase organic UV filters to be used in the water phase, creating formulations with a lightweight feel and enhanced UV protection.
The Silica UV Capsule series encapsulates organic UV filters, typically used in oil phases, within silica, enabling their use in the water phase to develop lightweight sun care formulations. This new series is an evolution of our Hybrid series (PMMA capsules), launched in 2007 and now selling over 40MT annually. By using silica instead of PMMA, these products address microplastic concerns.
Most organic UV filters require an oil phase, but SUNSIL-AB, SUNSIL-EHT, SUNSIL-DHHB, and SUNSIL-BLP are water-phase compatible. This flexibility allows formulators to use UV filters in both the oil and water phases, maximizing UV protection effectiveness.
In comparative studies, SUNSIL-AB demonstrated superior UV protection in both in-vivo and in-vitro tests at equivalent net content when compared to BMDBM in the oil phase.
Additionally, thanks to their lightweight feel, these silica capsules are ideal for O/W sun gel formulations where oil use is limited. You can create SPF50, PA++++ sun gel formulations with a non-sticky, light feel – without ethanol.
SUNSIL-AB, SUNSIL-EHT, SUNSIL-DHHB, and SUNSIL-BLP contain 30% organic UV filters in silica capsules, providing a more lightweight texture and higher UV protection.
