High UVB Protection Efficiency
Synergy with DHHB:
In formulations containing 10% DHHB, adding 1% EHT increases SPF by +7 units (e.g., from SPF 30 to 37).
At 5% EHT, SPF reaches 43 (ISO 24444:2019 testing protocol).
Absorption Peak: λmax = 314 nm (covers UVB spectrum: 290–320 nm).
Superior Photostability
Retains >95% efficacy after 2 hours of UV irradiation (1.5 MED, COLIPA guidelines), outperforming conventional UVB filters like Octinoxate.
Enhanced Safety Profile
Minimal Skin Penetration:
High molecular weight (823.07 g/mol) prevents transdermal absorption (OECD 428 in vitro skin permeation study).
Regulatory Compliance:
Approved under EU Cosmetics Regulation (EC No. 1223/2009) up to 5% concentration.
Formulation Flexibility
Compatible with organic and inorganic filters (e.g., ZnO, TiO₂, DHHB).
Stable in pH 4–8 systems and temperatures up to 80°C.
Optimal Usage:
Sunscreen Creams/Sprays: 3–5% EHT + 5–10% DHHB for balanced UVA/UVB protection.
Daily Moisturizers: 1–2% EHT for lightweight UVB defense.
Synergistic Additives:
Pair with antioxidants (e.g., Vitamin E acetate) to enhance free radical scavenging.
