Avobenzone uses
1. Broad spectrum UV absorption
UVA absorption capacity:
Avobenzone is a sunscreen agent that can absorb UVA in the entire wavelength range (approximately 315 to 400 nanometers), especially UVA with the highest absorption rate at 357 nanometers.
It is one of the few organic sunscreens that can absorb the UVA1 band, which is the area with the largest span of ultraviolet rays that most ultraviolet absorbers cannot protect.
Broad Spectrum Protection:
Because it blocks UVA I, UVA II, and UVB wavelengths, avobenzone is classified as a "broad spectrum" sunscreen, providing comprehensive UV protection.
2. Durability of sun protection effect
Although avobenzone breaks down over time when exposed to sunlight and reduces its effectiveness, its stability can be significantly improved by combining it with a light stabilizer such as octocrylene, thereby extending the durability of the sun protection.
3. Protect skin health
Reduce photoaging:
UVA is one of the main factors causing skin photoaging. Avobenzone helps keep skin young by absorbing UVA and reducing its damage to the skin.
Prevent cancer:
Studies have found that UVA may also be involved in the carcinogenesis process caused by sunlight. Effective protection with avobenzone helps reduce this risk.
4. Other applications
In addition to sunscreen products, avobenzone is also used to improve the stability of daily chemical products such as shampoo and shower gel, and to prevent color fading of dyed textiles and yellowing of wool textiles.
5. Security and Restrictions
The safety of avobenzone used in cosmetics has been recognized by multiple international regulatory agencies, such as the U.S. Food and Drug Administration (FDA) and the Cosmetics Directive of the European Union, which have approved its safe use concentration. .
However, the full risks of long-term use of avobenzone have not been determined. Since it is often used with light stabilizers, there may be a risk of skin irritation and low toxicity. Therefore, products containing avobenzone are not recommended for use by children and pregnant women.
In summary, avobenzone, as an efficient broad-spectrum UV absorber, plays an important role in sunscreen products. It not only provides comprehensive UV protection and reduces the risk of photoaging and canceration, but is also widely used in other daily chemical product fields. However, you should also pay attention to the safety risks it may bring when using it.
