UNI_EHT - The Third-Generation and most powerfull UVB Filter 

INCI: ETHYLHEXYL TRIAZONE

CAS: 88122-99-0 

MOLECULAR STRUCTURE

With growing awareness of sun protection, the demand for safer, longer-lasting sunscreens has led to the emergence of third-generation sunscreens. 

Third-generation sunscreens offer enhanced light stability and more enduring protection.

Their larger molecular weight reduces absorption and skin irritation, while also delivering a light skin feel and excellent spreadability.

UNI_EHT, also known as UV T150, is a high-purity, triazine-type UV absorber and a definitive third-generation sunscreen agent supplied by UNIcare from China. It represents the forefront of sunscreen technology, offering exceptional efficiency, broad-spectrum potential in synergy with other filters, and an enhanced safety profile.

Core Advantages 

Unmatched UVB Protection

As the most potent oil-soluble UVB filter available, UNI_EHT exhibits an exceptionally high molar extinction coefficient ( absorbance > 1500 at 314 nm). Its high efficacy allows for the achievement of high SPF values even at low concentrations, enabling more elegant cosmetic formulations with reduced total actives.

Superior Photostability

The molecular structure, featuring a stable central triazine ring, is highly resistant to photodegradation under prolonged UV exposure. This ensures long-lasting, consistent protection without a significant loss of efficacy, making it ideal for extended outdoor use.

Enhanced Safety Profile

Prevents UV-Induced Immunosuppression: By effectively absorbing UVB radiation, UNI_EHT mitigates damage to skin immune cells (e.g., Langerhans cells), thereby helping to maintain the skin's natural immune defenses and reduce associated risks.

High Affinity for Skin Keratin

The molecule binds strongly to keratin via hydrogen bonds and van der Waals forces. This minimizes skin penetration, reduces the potential for irritation, and enhances film durability on the skin's surface, resisting removal by friction or mild cleansing.

Excellent Water Resistance

The hydrophobic nature of its molecular structure ensures strong water resistance. It is not easily dissolved or washed away by water or sweat, making it an ideal component for waterproof and sweat-resistant sunscreen products.

Synergistic Broad-Spectrum Performance

While an elite UVB filter, UNI_EHT is designed to be combined with UVA filters such as UNI_DHHB. This combination delivers synergistic, balanced, and comprehensive protection across the entire UVA/UVB spectrum.

Application Note

UNI_EHT is easily incorporated into various sunscreen formulations by dissolving in the oil phase (e.g., GTCC, Dioctyl Carbonate) with heating.
