The efficacy of modern sunscreens and personal care products hinges on sophisticated chemical formulations designed to protect human skin from the damaging effects of ultraviolet (UV) radiation. Central to this protection are UV absorbers – chemical compounds that selectively absorb specific wavelengths of UV light. Among the most widely recognized and utilized is 2-Hydroxy-4-methoxybenzophenone, commonly known by its INCI name, Oxybenzone, or its CAS number 131-57-7. As a leading supplier of fine chemical ingredients, we aim to provide clarity on its role and benefits.

Understanding UV Radiation and Skin Damage

The sun emits UV radiation in three main forms: UV-A, UV-B, and UV-C. While UV-C is largely absorbed by the Earth's ozone layer, UV-A and UV-B rays penetrate the atmosphere and can cause significant harm to the skin. UV-B rays are primarily responsible for sunburn, while UV-A rays penetrate deeper, contributing to premature aging, wrinkles, and an increased risk of skin cancer. Effective sunscreens must therefore block or absorb a significant portion of both UV-A and UV-B radiation.

How 2-Hydroxy-4-methoxybenzophenone Works

2-Hydroxy-4-methoxybenzophenone is classified as a broad-spectrum UV filter, meaning it is effective across a wide range of UV wavelengths, including both UV-A and UV-B. Its chemical structure allows it to absorb UV photons and then dissipate this energy as heat through molecular rearrangement. This process effectively prevents the UV radiation from reaching and damaging skin cells. Key advantages of this compound, which make it a preferred choice for formulators, include:

  • High Absorption Efficiency: It absorbs UV light very effectively, allowing for lower concentrations to achieve desired Sun Protection Factor (SPF) and PPD (Persistent Pigmentation Darkening) values.
  • Good Photostability: While some UV absorbers can degrade under prolonged UV exposure, Benzophenone-3 offers a reasonable degree of photostability, especially when formulated with other UV filters.
  • Cosmetic Grade Purity: Manufactured to meet stringent cosmetic grade standards, ensuring safety and efficacy for topical application.
  • Cost-Effectiveness: As a widely produced chemical, it offers excellent value for money, a crucial factor for mass-market cosmetic production.
