Octocrylene characters
Absorbs UVA and UVB rays
Octocrylene is effective in absorbing and filtering out UVB radiation, which is responsible for causing sunburn and contributes to skin cancer. It also offers some protection against UVA rays, which can lead to premature aging and skin damage.
Stability and effectiveness
Octocrylene helps stabilize other UV filters in sunscreen products, improving their overall photostability. This means that the sunscreen remains effective for a longer period when exposed to sunlight.
Water-Resistant sunscreen products
Octocrylene helps maintain their effectiveness even when exposed to water or sweat.
Broad-Spectrum protection
When combined with other UV filters like avobenzone, octocrylene can provide broad-spectrum protection against both UVA and UVB radiation, offering comprehensive sun protection.
Octocrylene Use
Octocrylene is an organic sun filter. This filter mainly absorbs UVB radiation, which is responsible for tanning but also for sunburn and skin cancer.
Octocrylene is an active ingredient in sunscreen formulations to increase their SPF (Sun Protection Factor) and broad-spectrum protection. The main applications include sunscreens , moisturizers, foundations, lip balms, and anti-aging creams in cosmetics.
UV Absorber UV-3039 is a material in sunscreen products to be water resistant.
