Application:
Recommended for O/W sunscreen systems and suitable for selected W/O formulations. Sunsafe® Fusion C4 can be used in sunscreen lotions, creams and gels, as well as BB creams and foundations. For O/W systems, add at the final cooling stage at approximately 45-50°C and mix until uniform. It may be used alone or combined with physical UV filters, MBBT or other sunscreen carriers for broader formulation flexibility.
Key Benefits:
Broad-spectrum synergistic UV protection
Combines five UV filters covering UVA and UVB wavelengths. The lipid microsphere carrier promotes more uniform film formation on skin and can improve measured SPF/PFA performance versus the same level of free UV filters.
Reduced skin penetration and retention
In Franz diffusion testing, the carrier system significantly reduced skin retention of the incorporated UV filters compared with free-filter controls, supporting a lower-penetration formulation approach.
Improved stability and formulation convenience
Improves the solubility of avobenzone and BEMT and enhances avobenzone photostability. The product shows good water dispersibility and can be incorporated during the low-temperature stage, simplifying formulation processing.
Improved sensory performance and compatibility
Designed to reduce the heavy, greasy feel associated with high levels of lipophilic UV filters. Compatible with a wide range of emulsifiers and thickeners in O/W systems, with application flexibility across sun-care and color-cosmetic products.
