Key Benefits And Performance
This UV filter is recognized for its high efficiency due to broad-spectrum absorption capabilities, covering both UVA and UVB ranges. It acts as a synergistic agent when combined with other UV-B filters, effectively boosting the Sun Protection Factor (SPF) of the final product. Formulators appreciate its ease of incorporation into various bases. At standard temperatures, it is soluble in polar cosmetic oils while remaining insoluble in water, providing flexibility in emulsion design. Furthermore, it demonstrates excellent compatibility with other cosmetic ingredients and UV filters, reducing the total amount of absorber required to meet regulatory standards.
Industrial Applications
UV Absorber S was specifically designed to meet the rigorous needs of the modern cosmetic industry. It is primarily incorporated into sunscreen lotions and creams to provide reliable skin protection. Beyond sun care, it is also suitable for day care products and skin brightening formulations where UV protection is required to prevent photo-aging. The recommended concentration is typically up to five percent, though regulatory approvals in certain regions may allow up to ten percent. This versatility makes it a valuable asset for diverse product lines.
