Product Information of UV Absorber BP-5 (CAS 6628-37-1)

Sodium,5-benzoyl-4-hydroxy-2-methoxybenzenesulfonate (BP-5) is sodium salt of BP-4. It is a water-soluble neutral broad-spectrum ultraviolet absorber with high absorption efficiency, non-toxicity, no teratogenic side effects, good light and heat stability. It can improve the stability of shampoos, body washes and fragrances containing polyacrylic substances. It is mainly used in water-soluble chemical sunscreens, sunscreens and lotions. It can improve the durability of dyed textiles, prevent yellowing of wool textiles and prevent synthetic fabrics. It can be used in hair products such as hair gels and mousses to prevent hair damage and whitening caused by ultraviolet radiation.
