Avobenzone is a critical component in the formulation of effective sunscreens, primarily lauded for its ability to provide broad-spectrum UVA protection. As a leading chemical manufacturer and supplier in China, we understand the intricacies of this compound and are dedicated to providing formulators with the highest quality Avobenzone (CAS 70356-09-1). This article will explore the essential chemical properties of Avobenzone and offer insights for procurement managers and R&D scientists seeking a dependable supplier.

The Chemistry Behind Avobenzone's UV Protection

Avobenzone, or Butyl Methoxydibenzoylmethane, belongs to the class of dibenzoylmethane derivatives. Its molecular structure is specifically designed to absorb ultraviolet radiation, particularly within the UVA spectrum (315-400 nm). It functions by absorbing UV light and converting it into heat, which is then dissipated from the skin. This mechanism is vital for preventing long-term skin damage, such as premature aging and an increased risk of skin cancer, both associated with UVA exposure.

The absorption maximum of Avobenzone is around 357 nm, positioning it as a highly effective filter for the longer UVA wavelengths. While it is known to be photounstable, meaning it can degrade under UV exposure if not stabilized, its inclusion in formulations remains crucial. Modern sunscreen technology utilizes stabilizers like octocrylene, homosalate, or antioxidants to enhance Avobenzone's photostability, ensuring prolonged efficacy.

Key Specifications to Consider When Buying Avobenzone

For procurement professionals and R&D scientists, understanding product specifications is key to making informed purchasing decisions. Our Avobenzone is manufactured under strict quality controls. The typical specifications include:

  • Appearance: White to off-white crystalline powder.
  • Assay: 99.0% - 105.0%.
  • Melting Point: 81°C - 86°C.
  • Loss on Drying: Maximum 0.5%.
  • Chromatographic Purity: Individual impurities max 3.0%, sum of impurities max 4.5%.
  • Specific Gravity: 1.037-1.041.
  • Acidity: Maximum 1.0 mg KOH/g.

These parameters ensure that the Avobenzone purchased from our facility will consistently meet the demands of high-performance cosmetic applications.
