Description

Avobenzone is a high-performance, oil-soluble organic compound widely recognized as a critical broad-spectrum UVA filter. Its primary value lies in its exceptional ability to absorb long-wave UVA rays, which are a major contributor to skin aging and long-term photodamage. This makes it an indispensable active ingredient for formulators in the personal care and cosmetics industries, specifically for sunscreens, daily moisturizers with SPF, and anti-aging skincare products. Global manufacturers rely on its efficacy to meet stringent regulatory standards and consumer demand for advanced photoprotection.

Application

• Broad-Spectrum Sunscreen Formulations: As a key UVA filter in sun care products (SPF 15-50+), lotions, sprays, and sticks.
• Daily Wear & Cosmetic Products: Incorporated into facial moisturizers, foundations, BB/CC creams, and lip balms for everyday UVA protection.
• Anti-Aging & Skincare Serums: Used in products designed to prevent photoaging, wrinkles, and loss of skin elasticity caused by UVA exposure.
• Professional Sun Care Lines: For formulating water-resistant, high-SPF, and sensitive skin sunscreens.
• Hair Care Products: Added to sun-protective hair sprays, leave-in conditioners, and oils to shield hair from UV damage.
• After-Sun & Repair Products: Used in formulations aimed at soothing and repairing skin after sun exposure.
