FAQ (Frequently Asked Questions)
1. What is Avobenzone?
Avobenzone is an oil-soluble chemical sunscreen agent that provides broad-spectrum protection against UVA rays. It is widely used in sunscreens, skincare products, and cosmetics to prevent premature aging and sun damage caused by UVA exposure.
2. What is the CAS Number and INCI Name of Avobenzone?
CAS Number: 70356-09-1
INCI Name: Butyl Methoxydibenzoylmethane
3. What are the benefits of using Avobenzone in personal care products?
Broad-Spectrum UVA Protection: Effectively absorbs long-wave UVA rays (320–400 nm) to prevent sun-induced aging and DNA damage.
Enhances Sun Protection: Often combined with UVB filters (e.g., Octocrylene, Homosalate) for full-spectrum sun protection.
Non-Comedogenic: Suitable for various skin types, including oily and acne-prone skin.
4. What are the common applications of Avobenzone in personal care?
Sunscreens & Sunblocks: A primary UVA filter in broad-spectrum SPF formulations.
Moisturizers with SPF: Provides daily sun protection in skincare products.
BB & CC Creams: Incorporated into tinted sunscreens and makeup products for sun defense.
Lip Balms with SPF: Shields lips from sun damage and dryness.
5. Is Avobenzone safe for use in personal care products?
Yes, Avobenzone is approved by the FDA, EU, and other regulatory bodies for use in sunscreens at recommended concentrations (up to 3% in the U.S. and 5% in the EU). However, it may degrade when exposed to sunlight, so it is often stabilized with other UV filters like Octocrylene.
6. Can Avobenzone cause skin irritation?
Avobenzone is generally well-tolerated, but some individuals with sensitive skin may experience mild irritation or allergic reactions. Conducting a patch test before use is recommended.
7. Is Avobenzone environmentally friendly?
Avobenzone has been associated with potential environmental concerns, particularly in marine ecosystems. Some regions, such as Hawaii and Palau, have restricted the use of certain chemical UV filters in sunscreens to protect coral reefs.
8. Are there alternatives to Avobenzone in personal care products?
Yes, alternatives include:
Zinc Oxide & Titanium Dioxide: Mineral sunscreen filters that provide broad-spectrum protection and are reef-safe.
Tinosorb S & Tinosorb M: Advanced broad-spectrum UV filters used in European and Asian sunscreens.
Mexoryl SX & Mexoryl XL: Photostable UVA filters with high efficiency (not widely available in the U.S.).
