Applications
1. Sunscreens and Sun Care Products
Widely used in creams, lotions, sprays, and lip balms as a UV-B filter.
Protects skin from sunburn and photoaging by absorbing harmful UV-B rays.
2. Cosmetics and Personal Care
Incorporated into makeup products, moisturizers, and hair care items that offer SPF (sun protection factor).
Helps maintain product stability and effectiveness during sun exposure.
3. Polymer and Plastic Protection
Occasionally used to protect plastic products and films from UV degradation, especially in packaging and outdoor applications.
Benefits
Effective UV-B Protection: Absorbs UV-B radiation, helping prevent skin erythema and DNA damage.
Oil-Soluble: Compatible with anhydrous and water-resistant sunscreen formulations.
Photostability: Offers moderate stability under sunlight when used with other stabilizers or in combination with other UV filters.
Enhances SPF: Boosts the overall sun protection factor in combination with other UV absorbers (e.g., avobenzone, octocrylene).
Conclusion
2-Ethylhexyl 4-dimethylaminobenzoate (Padimate O, CAS 21245-02-3) is a UV-B filter commonly used in sunscreens and sun-protective cosmetics. With excellent oil solubility and effective UV-B absorption, it contributes significantly to sunburn prevention and SPF enhancement in skincare formulations. While effective, regulatory status varies by country, and it is often used in conjunction with other UV stabilizers for optimal performance and safety.
