Why Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) Is the Future of UVA Protection

When it comes to sun care, not all UV filters are created equal. While many people focus on SPF values (which mainly measure UVB protection), the truth is that UVA rays—the ones responsible for photoaging, pigmentation, and long-term skin damage—can be just as harmful. This is where Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB, CAS 302776-68-7) steps in.

What Makes DHHB Stand Out?

l Broad UVA Coverage: DHHB specifically targets long-wave UVA rays (320–400 nm) with a peak absorption at ~354 nm, protecting deep layers of the skin where photoaging begins.

l Outstanding Photostability: Unlike older UVA filters such as Avobenzone, which degrade quickly under sunlight, DHHB remains stable. This means long-lasting protection and fewer formulation issues for skincare brands.

l Formulation-Friendly: Oil-soluble, compatible with a wide range of sunscreen agents, and works well in creams, lotions, and high-SPF products without leaving a heavy feel.

Safety and Performance

DHHB has been extensively tested for safety, showing low irritation potential and good skin compatibility. It’s trusted worldwide in premium sunscreens and anti-aging skincare products for delivering consistent UVA protection.

Global Regulatory Status

DHHB has gained wide regulatory approval, reinforcing its role as a next-generation UV filter:

l European Union: Approved since 2005, up to 10% concentration in cosmetics.

l Japan, Taiwan, South America, and more: Widely authorized at up to 10%.

l United States: Not yet FDA-approved as a sunscreen active, but present in imported and hybrid formulations.

Why It Matters for Sunscreen Innovation

Consumers are increasingly demanding broad-spectrum, photostable, and safe sun protection. With its superior UVA coverage and stability, DHHB is quickly becoming a go-to filter for formulators seeking to elevate their sunscreen and skincare products.
