Tinosorb S: chemical UV filter in skincare products, offering broad-spectrum protection against UVA and UVB radiation.
Tinosorb S is also known for its broad-spectrum UV protection. It primarily protects against UVA and UVB rays, which can cause skin damage, sunburn, and premature aging. It is photostable, which means it doesn't degrade when exposed to sunlight, making it an effective and long-lasting sunscreen ingredient.
Skin Benefits
Broad-Spectrum Protection: Tinosorb S provides effective protection against both UVA and UVB radiation. It absorbs UVA rays in the range of 320 to 400 nanometers and UVB rays in the range of 280 to 320 nanometers. This broad-spectrum coverage helps prevent sunburn, photoaging, and reduces the risk of skin cancer.
Photostability: Tinosorb S is highly photostable, meaning it remains effective when exposed to sunlight. Unlike some other UV filters that can degrade upon UV exposure, Tinosorb S maintains its protective properties over time, providing reliable sun protection throughout sun exposure.
Enhanced UV Absorption: Tinosorb S has a high molar extinction coefficient, which means it efficiently absorbs UV radiation. This allows for lower concentrations of Tinosorb S to be used in sunscreen formulations while still providing high levels of UV protection, contributing to lighter and more cosmetically elegant sunscreen products.
Oil Solubility: Tinosorb S is lipophilic (fat-soluble), making it compatible with oil-based sunscreen formulations. Its oil solubility ensures even distribution on the skin and enhances the water-resistance of sunscreen products, making them more durable in outdoor and water-related activities.
