The direction of today’s suncare market is becoming increasingly clear.
Low-viscosity formats-led by sun serums and sun ampoules-are rapidly gaining traction, evolving beyond a passing trend to become the new standard.

However, translating this trend into formulation is far from straightforward.
By nature, sun ampoules are low in viscosity-bringing several practical challenges:

1. 1. Can sufficient SPF/PA be maintained at low viscosity?
2. 2. Can organic UV filters be remain stable without phase separation?
3. 3. Can a lightweight texture still deliver satisfying hydration?

The simplest way to solve these challenges.
With HYDROSOLA, formulating sun ampoules becomes easier and more efficient.

■ HYDROSOLA: A New Way to Use Organic UV Filters-In the Water Phase

The HYDROSOLA series is a water-dispersible system that stabilizes organic UV filters within a multi-layered structure.
With submicron particles below 1 μm, the filters are encapsulated and designed to disperse rapidly and uniformly in the water phase.
This structural advantage makes a meaningful difference in formulation.

• Easy to Use
  Enables fast and uniform dispersion of organic UV filters in the water phase-without the need for additional heating.
• High UV Performance
  Micro-emulsion technology finely disperses filter particles, enhancing overall UV protection efficiency.
• Excellent Stability
  Delivers stable formulations without the need for additional emulsifiers.

■ A Minimalist Sun Ampoule Formula

Formulated with 30% HYDROSOLA-EBD, this sun ampoule achieves SPF 50, PA++++ without complex combinations of organic UV filters. At the same time, it delivers a lightweight, low-viscosity texture with a fresh, non-greasy feel.

■ Proven High Performance-Verified In Vivo

In in vivo testing, a formulation containing 30% HYDROSOLA-EBD achieved SPF 50 and PA 20-without the need for complex UV filter combinations. This level of protection, typically requiring carefully optimized multi-filter systems, is delivered through a single, streamlined solution.

■ Stable Low-Viscosity Formulation-No Additional Emulsifiers Required

Even at low viscosity (below 5,000 cps), the formulation maintained stability for one month at 50°C.
No oil phase separation, filter sedimentation, or structural breakdown-common issues in low-viscosity systems-were observed.

As a result, HYDROSOLA reduces formulation complexity and processing burden, while delivering high SPF, low viscosity, and stability-all in one solution.
In other words, powerful and stable low-viscosity suncare is now achievable-without complex formulation design.

■ In Summary

HYDROSOLA redefines what was once a trade-off delivering both performance and sensoriality in a single approach.

Rather than relying on increasingly complex formulations, it’s time for a more efficient solution. Experience how HYDROSOLA enables easier, more refined low-viscosity suncare formulations.

🔎 Summary Q&A
Q1. Can SPF 50-level protection be achieved in low-viscosity suncare? Yes.
With approximately 30% HYDROSOLA, it is possible to achieve SPF 50 and PA 20-without complex combinations of organic UV filters.
👉 High SPF performance, even in low-viscosity systems

Q2. Can organic UV filters be used directly in the water phase? Typically, no-but with HYDROSOLA, yes.
Its multi-layered structure stabilizes organic UV filters, allowing them to disperse uniformly in the water phase.
👉 Redefining the limitation of “organic UV filters = oil phase”

Q3. How is emulsion stability maintained in low-viscosity formulations?
HYDROSOLA utilizes a micro-emulsion-based fine particle structure to keep droplets small and uniformly distributed. This enables stable formulations even in low-viscosity systems without additional emulsifiers.
👉 Stable low-viscosity formulations, no extra emulsifiers needed

Q4. What types of formulations is HYDROSOLA best suited for?
It is ideal for low-viscosity suncare formats such as sun serums, ampoules, and mists.
Especially effective for developing trend-driven products that require fast absorption and a fresh skin feel.
👉 Optimized for next-generation lightweight suncare
