The efficacy of sunscreen is judged not only by its ability to prevent sunburn but also by its capacity to protect against the more insidious, long-term effects of sun exposure, particularly those caused by UVA radiation. Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB) has emerged as a critical ingredient for achieving superior UVA protection and ensuring the longevity of sunscreen products. This article, presented by NINGBO INNO PHARMCHEM CO.,LTD., a leading supplier of advanced cosmetic ingredients, explores the role of DHHB in modern sunscreen formulations.

The Critical Role of UVA Protection in Sunscreens

While SPF ratings primarily quantify protection against UVB rays (responsible for sunburn), UVA rays (responsible for photoaging and contributing to skin cancer) are equally damaging. Effective sunscreens must provide robust protection across the entire UV spectrum. UVA rays are persistent, penetrating deeper into the skin and causing long-term damage such as wrinkles, loss of elasticity, and increased risk of skin cancer. Therefore, incorporating a potent and stable UV-A filter is non-negotiable for high-performance sun care products.

DHHB: A Superior Choice for UVA Defense

Diethylamino Hydroxybenzoyl Hexyl Benzoate (CAS No. 302776-68-7) excels as a UV-A absorber due to several key properties:

  • High UVA Absorption: DHHB exhibits a strong absorption peak in the UV-A range (around 354 nm), effectively neutralizing these harmful wavelengths and providing critical protection against photoaging and DNA damage.
  • Exceptional Photostability: One of DHHB's most significant advantages is its remarkable photostability. Unlike many other organic UV filters that degrade upon prolonged exposure to sunlight, DHHB maintains its UV-absorbing capacity, ensuring consistent and reliable protection throughout the day. This stability translates to better product performance and consumer satisfaction.
  • Free Radical Scavenging: Beyond its primary UV absorption, DHHB possesses the ability to scavenge free radicals, which are generated by UV exposure and contribute to cellular damage. This dual action enhances the overall protective benefits of the formulation.
  • Formulation Versatility: As an oil-soluble ingredient, DHHB integrates seamlessly into the oil phase of sunscreen emulsions, offering formulators flexibility in creating various product textures, from lotions to creams and oils.
