1. Acts Drometrizole as a high-efficiency UV stabilizer in plastic & coating production, providing full-spectrum UV protection to prevent polymer degradation and discoloration under outdoor exposure.

2. Serves UV-P CAS 2440-22-4 as a light stabilizer in cosmetic formulations, synergizing with organic UV filters to enhance photostability of skin care and hair care products effectively.

3. Functions as a photoprotective additive in textile finishing, improving UV resistance and color fastness of dyed fabrics for outdoor textile applications.

Store Drometrizole (CAS 2440-22-4, white crystalline powder, faint aromatic odor, non-flammable, mp 137-141℃, purity ≥99%) at 10–25℃ in sealed amber glass/HDPE containers in a cool, dry, dark and well-ventilated area. Isolate from strong oxidants, acids, alkalis and moisture to avoid photodegradation and oxidation. Wear nitrile gloves, safety goggles and dust mask; avoid dust inhalation, skin/eye contact and ingestion to prevent mild irritation. Reseal tightly post-use; dispose of waste per local UV absorber & fine chemical environmental regulations.

Drometrizole is an industrial UV stabilizer and cosmetic additive, not for direct pure-form human contact or ingestion; long-term skin contact may cause mild dryness, and accidental intake will lead to gastrointestinal discomfort. In regulated applications, UV-P CAS 2440-22-4 features excellent full-spectrum UV absorption and photostability, has good compatibility with polymers and cosmetic matrices, and exhibits remarkable synergistic effects with other light stabilizers to extend product service life.
