Oil Soluble Suncreen Ingredient Avobenzone

Product Detail

Cosmate^®AVB ,Avobenzone,Butyl Methoxydibenzoylmethane. It is a derivative of dibenzoyl methane. A wider range of ultraviolet light wavelengths can be absorbed by avobenzone. It is present in a lot of broad-range sunscreens that are commercially available. It functions as a sunblock. A topical UV protector with a broad spectrum, avobenzone blocks UVA I, UVA II, and UVB wavelengths, reducing the damage that UV rays can do to the skin. Avobenzone (BMDM, Butyl methoxydibenzoylmethane) is a sun screen chemical that offers broad-range protection against UVA rays. Avobenzone absorbs both UV-(380-315 nm that is associated with long term skin damage) and UV-B (315-280 nm that causes sunburn) rays. Avobenzone is known as one of the most effective sunscreen ingredient. Avobenzone is a widely used chemical sunscreen agent known for its ability to provide broad-spectrum protection against UVA rays. It is one of the most effective UVA filters available and is commonly found in sunscreens, moisturizers, and other sun care products. Its ability to absorb UVA radiation helps prevent photoaging, sunburn, and long-term skin damage.

Key Functions of Avobenzone

*Broad-Spectrum UVA Protection: Absorbs UVA rays, which are responsible for premature aging and skin damage. *Photoaging Prevention: Protects the skin from UVA-induced wrinkles, fine lines, and loss of elasticity. *Sunburn Protection: Works alongside UVB filters to provide comprehensive protection against sunburn. *Stabilized Formulations: Often used with stabilizers to enhance its photostability and effectiveness. *Skin Compatibility: Suitable for a wide range of skin types, including sensitive skin. Avobenzone Mechanism of Action *UVA Absorption: Absorbs UVA radiation (320-400 nm) and converts it into less harmful heat energy, preventing DNA damage. *Free Radical Neutralization: Helps reduce the formation of free radicals caused by UV exposure, minimizing oxidative stress. *Collagen Protection: Prevents UVA-induced breakdown of collagen and elastin, maintaining skin firmness and elasticity. *Synergistic Effects: Often combined with UVB filters (e.g., octinoxate) and stabilizers (e.g., octocrylene) to enhance its photostability and broad-spectrum protection. Avobenzone Advantages & Benefits *Effective UVA Protection: Provides superior protection against UVA rays, which are a major cause of photoaging. *Broad-Spectrum Compatibility: Works well with other UV filters to offer full-spectrum sun protection. *Photostability: When stabilized, it remains effective under prolonged UV exposure. *Gentle on Skin: Suitable for all skin types, including sensitive skin, when formulated correctly. *Regulatory Approval: Approved by major regulatory bodies, including the FDA and EU, for use in sunscreens.
