Product name: Benzophenone-12
CAS No: 1843-05-6

Benzophenone-12 is an organic compound used as a UV filter and stabilizer in cosmetic and personal care products, especially in sunscreens and hair care formulations. It is effective at absorbing UV radiation, particularly UVA and some UVB rays, providing broad-spectrum protection from the sun's harmful effects. Benzophenone-12 is valued for its ability to stabilize other sunscreen agents, enhancing the overall efficacy and photostability of the product. This makes it an important ingredient in formulations designed to provide prolonged sun protection and prevent skin damage, premature aging, and sunburn.

Application and Effect
Benzophenone-12 is primarily used in sunscreens and other sun care products to protect the skin from the damaging effects of UV radiation. UVA rays contribute to photoaging (wrinkles, fine lines, and sagging) and deeper skin damage, while UVB rays are responsible for sunburn. By absorbing and blocking these harmful rays, Benzophenone-12 helps to minimize the risk of both immediate and long-term skin damage, including sunburn and increased skin cancer risk.   In addition to its UV-blocking properties, Benzophenone-12 enhances the photostability of sunscreen formulations. Many sunscreen ingredients, especially those that provide protection against UVA radiation, degrade when exposed to sunlight, reducing their effectiveness over time. Benzophenone-12 helps prevent the breakdown of other active ingredients, maintaining the sunscreen's effectiveness even after prolonged sun exposure.   Benzophenone-12 is also used in hair care products, such as shampoos and conditioners, where it helps protect hair from UV-induced damage, including color fading, dryness, and brittleness. Its UV-blocking properties help maintain the integrity of hair color and texture, especially in formulations aimed at color-treated or sun-exposed hair.   The ingredient is also used in moisturizers, foundations, and other daily skincare products that offer sun protection, providing an additional layer of defense against UV damage. While generally considered safe in cosmetic formulations, as with any UV filter, some individuals with sensitive skin may experience irritation, so it is advisable to patch-test products before regular use.
