Hello from Sunjin Beauty Science,

Silicone-Free and Microplastic-Free have become the new standard in the global base makeup market. However, removing silicone presents formulators with a new challenge.

"Can makeup still deliver long-lasting performance without silicone?“

Silicone has long been a key ingredient for improving makeup longevity thanks to its excellent water repellency and pigment dispersibility. Without silicone, pigments are more easily wetted by sebum and sweat, leading to darkening, color shift, and makeup breakdown over time.

Ultimately, the key to a successful Silicone-Free formulation is not simply replacing silicone —it is reproducing the performance that silicone has traditionally provided.

The TINA (Totally Innovative Natural Coating Agent) Series from Sunjin Beauty Science was developed to meet this challenge. Featuring 100% Natural Origin Coating Technology, TINA delivers outstanding pigment dispersibility, superior water repellency, excellent formulation compatibility, and exceptional long-lasting performance, making it the next-generation coated pigment solution.

1. TINA Coating Technology – Stronger Bonding for Longer Performance

The performance of a coated pigment depends not only on the coating material itself, but also on how the coating is applied.
Conventional blending methods rely on physical adhesion between the coating material and pigment surface. As a result, the coating layer can easily detach during high-temperature processing or in various oil systems, causing pigment agglomeration, poor dispersion, formulation instability, and ultimately reduced product quality.
TINA utilizes Sunjin's proprietary Chemical Bonding Technology to create a strong chemical bond between the natural coating agent and the pigment surface. This robust coating layer provides outstanding heat resistance and coating stability while maintaining excellent performance across a wide range of formulations.
In a 100°C Boiling Stability Test, TINA demonstrated significantly better coating stability than conventional naturally coated pigments using fatty acid or amino acid coatings.

2. Superior Dispersibility Beyond Silicone-Coated Pigments

Even in highly polar ester oils—which are among the most challenging media for pigment dispersion—TINA exhibits remarkably low dispersion viscosity, delivering dispersibility comparable to or even better than conventional silicone-coated pigments.
Uniform pigment dispersion contributes to vibrant color payoff, a smoother sensory experience, and improved manufacturing efficiency.

3. Low Wetting Technology that Repels Sebum and Sweat

One of the primary causes of makeup deterioration is pigment wetting by sebum and sweat. Artificial sebum testing showed that TINA exhibits significantly slower wetting behavior than conventional AS-coated pigments, demonstrating excellent Low Wetting characteristics.
By minimizing the effects of sebum and sweat, TINA helps maintain the original makeup finish for a longer period without premature breakdown.

4. Anti-Darkening, Long-Lasting Performance & Stability

In an 8-hour in vivo evaluation, formulations containing TINA recorded a color change (ΔE) of only -0.42, demonstrating outstanding Anti-Darkening performance compared with global benchmark products.
TINA helps maintain a fresh, bright complexion while providing exceptional Long-lasting performance. In both Silicone System and Silicone-Free System formulations, pigment agglomeration is minimized to maintain uniform dispersion over time. Its excellent formulation stability and storage stability ensure high reproducibility throughout both R&D and manufacturing processes.

5. Delivering Performance While Supporting Clean Beauty

Outstanding makeup performance alone is no longer enough.
Today, sustainability and regulatory compliance have become key competitive advantages in the global cosmetics market. The TINA Series is COSMOS Approved and has a Natural Origin Index 1.0 (100% Natural Origin), making it ideal for Silicone-Free and Microplastic-Free claims. It enables brands to meet global Clean Beauty trends, including Sephora Clean standards, while maintaining the high-performance characteristics traditionally associated with silicone-coated pigments.

6. More Than a Silicone Alternative—Performance Without Compromise

The TINA Series is more than simply a naturally coated pigment.
It delivers silicone-level dispersibility, superior water repellency, excellent formulation stability, Anti-Darkening performance, and long-lasting wear while fully supporting 100% Natural Origin, Silicone-Free, and Microplastic-Free technologies.
From high-performance base makeup to sustainability and evolving global clean beauty standards,
The TINA Series from Sunjin Beauty Science sets a new benchmark for next-generation coated pigments.
