As a cosmetic formulator, selecting the right UV filters is paramount for creating effective sunscreens. Avobenzone (CAS 70356-09-1) stands out as a globally approved UVA filter, celebrated for its ability to absorb a wide spectrum of UVA radiation, thus preventing premature skin aging and damage. However, its inherent photostability challenges have been a subject of extensive research and formulation development. Understanding these challenges and implementing effective stabilization strategies is key for any manufacturer aiming to produce high-performance sun care products. At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing not just high-quality Avobenzone but also the technical insights necessary for its optimal application.

Understanding Avobenzone's Photostability Issues

Avobenzone, chemically known as butyl methoxydibenzoylmethane, is highly effective at absorbing UVA rays (320-400 nm). Unfortunately, it is prone to photodegradation, meaning it can break down upon exposure to UV light, losing its efficacy over time. This degradation can also lead to the formation of free radicals, which can be detrimental to the skin. For formulators and manufacturers, this instability necessitates careful consideration during product development. Simply including Avobenzone without proper supporting ingredients can result in a sunscreen that offers diminishing protection as the day progresses, especially during prolonged outdoor activities.

Key Strategies for Stabilizing Avobenzone

To ensure that Avobenzone delivers consistent and reliable UVA protection, formulators commonly employ several stabilization techniques. These methods are crucial for any supplier or manufacturer looking to offer a superior product.

  • Pairing with Photostabilizers: The most prevalent approach is to combine Avobenzone with other UV filters that act as photostabilizers. Ingredients like Octocrylene, Tinosorb S (Bemotrizinol), and Tinosorb M (Bisoctrizole) are widely recognized for their ability to absorb UV radiation and transfer energy away from Avobenzone, thereby preventing its degradation. When you buy Avobenzone, consider these synergistic partners for your formulations.
  • Incorporating Antioxidants: Antioxidants such as Vitamin E (Tocopherol), Vitamin C (Ascorbic Acid), and plant-derived polyphenols play a vital role. They help to neutralize the free radicals that might be generated during Avobenzone's degradation process, thus offering an additional layer of protection for the skin and enhancing the overall stability of the formulation.
  • Encapsulation Technology: Advanced formulation techniques include microencapsulating Avobenzone. This process involves enclosing the Avobenzone particles within a protective shell, shielding them from light and oxygen, and controlling their release. This not only enhances photostability but can also reduce potential skin irritation.
  • Combination with Mineral Filters: Layering Avobenzone with physical blockers like Zinc Oxide and Titanium Dioxide can also improve overall sunscreen stability. These mineral filters reflect UV radiation, reducing the load on the chemical filters and indirectly protecting Avobenzone from rapid degradation.
