What is 2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7?

Ensulizole(PBSA) 2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 is a water-soluble sunscreen ingredient, a sulfonated UV absorber characterized by strong absorption of UVB and partial absorption of UVA. ChemicalbookEnsulizole can damage DNA through the production of reactiveoxygenspecies(ROS) under ultraviolet light or sunlight.

Application

1. Cosmetics

Sunscreen function: 2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 is a highly efficient ultraviolet absorber, which can absorb 260-340 nanometers of ultraviolet light, especially the UVB band, but also absorb part of the UVA band, which can effectively block the damage of ultraviolet light to the skin, prevent skin sunburn, tanning, light aging, etc., often added to sunscreen, moisturizing sunscreen water and other products.

Improve the stability of the formula: with good water solubility, durability, dispersion, low migration, good thermal stability, can keep the texture of sunscreen and other products fresh, but also inhibit the decomposition of other UVB isolation agents, help to improve the stability of the cosmetics formula and the durability of the sunscreen effect.

2. Paint field: 2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 can be used as an ultraviolet absorber of water-based paint, which can absorb ultraviolet light, reduce the damage of ultraviolet light to the paint, improve the weatherability and service life of the paint, prevent the paint from fading, chalking, cracking and other problems, so that the paint can better maintain its performance and appearance in the outdoor environment.

3. Chemical materials: 2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 is used to manufacture outdoor overhead cable materials with weather resistance and oxidation resistance, which can absorb ultraviolet rays, reduce the aging effect of ultraviolet rays on cable materials, and improve the service life and performance of cables.

4. Bionic sensor field: 2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 is can be used to manufacture bionic sensors for the determination of 4-methylbenzyl camphor (4-MBC).

5. Grease field: 2-Phenylbenzimidazole-5-sulfonic acid CAS 27503-81-7 can be nucleophilic substituted with liquid bromine to prepare brominated 2-phenylbenzimidazole-5-sulfonic acid, and then react with the amino group of 3,4,4' -triamino-diphenyl ether to produce intermediate products, and then further react with isocyanate to synthesize polyurea thickener for preparing polyurea grease.

6. Other fields: It can be used as an analytical reagent for scientific research experiments, and can also be used in the preparation of supramolecular intercalation structural materials. The products after intercalation can be used as an excellent ultraviolet absorber to improve the anti-ultraviolet aging ability of composite materials.
