DHHB is approved for use up to 10% concentration in the EU, Japan, and China. It is not permitted in sunscreen formulations in the USA but may be used for product protection.
DHHB’s high photostability and strong UVA absorption (up to 400 nm) make it an ideal ingredient for long-lasting, broad-spectrum sunscreens. It helps prevent degradation of other active ingredients, ensuring consistent protection
As an oil-soluble filter, DHHB must be incorporated into the oil phase of O/W emulsions. It is typically used alongside emulsifiers and co-filters like Octocrylene to ensure dispersion, photostability, and optimal UV protection.

DHHB acts as a broad-spectrum UVA absorber, designed to protect skin from the harmful effects of long-wave UVA radiation. It is formulated in cosmetic and dermatological products to prevent photo-aging, hyperpigmentation, and UV-induced skin damage. Its oil-solubility and photostability make it ideal for water-resistant and long-lasting formulations in personal care products.
