Sunscreen has long evolved from a “seasonal care” product to a year-round essential. Consumers now expect more—not only must sunscreens provide reliable protection, but they must also feel pleasant on the skin. Lightweight, non-greasy texture with high SPF performance has become the core demand for the next generation of sunscreens.
In response, a solution that balances stability and excellent skin feel has emerged: UNI-POWDER XSorb Chemical & Mineral UV Filter Emulsified Water Slurry.
It is not a simple blend of UV filters, but a ready-to-use pre-dispersed system. Through innovative structured emulsion technology, chemical and mineral UV filters coexist stably, greatly simplifying formulation processes while enhancing product stability. This makes it possible to achieve high SPF protection alongside a light, invisible skin feel.
Ingredient Analysis: Innovative Emulsion System Ensures Stable Chemical & Mineral UV Filter Integrated Compounding
XSorb uses a scientifically balanced UV filter system, combining five organic and one mineral UV filter for a total UV filter content exceeding 50%. This system, paired with efficient emulsifiers and a polyol-based preservative system, further enhances product stability.
Performance Validation: Multiple Tests Demonstrate Exceptional Stability and Protection
● Stable from Micro to Macro Scale
High-content organic UV filters are prone to crystallization, which can compromise both stability and UV protection. In contrast, XSorb remains clear with no floating particles under the same test conditions, and microscopic examination shows no crystallization, proving the excellent stability of its UV filter system.
Diluted to 10%, XSorb was subjected to high and low temperature stability tests for one month. The results showed no significant changes in viscosity or particle size, and microscopic examination revealed no crystallization, demonstrating that XSorb maintains excellent system stability even under extreme conditions.
● Enhances Sunscreen Performance, Unlocking Full PA++++ Protection
XSorb can significantly boost sunscreen efficacy. Studies show that, with the same total UV filter content, a formulation containing 35% XSorb achieves an SPF of 70.96, compared to SPF 56.28 for a standard formulation—an increase of approximately 1.3×. At the same time, the PA rating improves from +++ to ++++, making it a highly effective UV filter boosting solution.
Application Advantages: Efficient Formulation Compatibility, Enhanced Production and User Experience

Simplified Production, Significantly Improved Development Efficiency
Using XSorb not only enhances sunscreen performance but also boosts production efficiency. Laboratory tests show that preparing 100 g of an oil-in-water sunscreen formulation with individual UV filters takes 80 minutes, whereas using the slurry requires only 50 minutes, saving approximately 37.5% of production time. Greater time savings are expected at larger manufacturing scales.
The chemical & mineral UV filter emulsified water slurry may appear to be just an “intermediate step” in a formulation, but it is actually a key factor determining the final performance of sunscreen products. UNI-POWDER aims to provide brands and R&D partners with a more stable, user-friendly raw material option through this innovative slurry.
