Phenylbenzimidazole Sulfonic Acid (Eusolex 232) UV Protective Sunscreen Raw Material-CAS 27503-81-7

Phenylbenzimidazole Sulfonic Acid (Eusolex 232) UV Protective Sunscreen Raw Material-CAS 27503-81-7

• Phenylbenzimidazole Sulfonic Acid, commercially known as Eusolex 232, is a high-purity cosmetic grade water-soluble UVB filter refined by advanced sulfonation reaction, purification and recrystallization technology.

• It is a unique and widely used core functional raw material in the global high-end sunscreen and personal care industry, distinguished from most oil-soluble sunscreen agents on the market.

• Different from traditional oil-soluble sunscreen agents with heavy texture, easy to cause greasy feeling and poor compatibility with water-based formulas, and ordinary water-soluble sunscreen agents with low UV absorption efficiency and poor photostability, Eusolex 232 has a unique phenylbenzimidazole sulfonic acid molecular structure, which is a typical water-soluble UVB absorber.

• It can efficiently absorb ultraviolet rays in the 280-320nm band, with a peak absorption at 306nm, forming a uniform and dense protective barrier on the skin surface to effectively resist UVB radiation damage, prevent skin sunburn, redness, peeling and long-term photoaging problems such as fine lines, pigmentation and skin roughing.

• As a multi-functional sunscreen raw material integrating UV protection, formula synergism and texture optimization, it not only has excellent UVB absorption capacity, but also can act as a synergist for other UV filters (such as Avobenzone, Octinoxate and Zinc Oxide), improving the photostability and SPF value of other sunscreen agents, avoiding their decomposition under sunlight, and extending the effective protection time of sunscreen products. It is white crystalline powder with good water solubility, can be quickly dissolved in the water phase of cosmetic formulas, will not cause heavy or greasy feeling on the skin, and will not leave white residue on the skin surface, bringing a refreshing, light and comfortable use experience.

• The product has excellent chemical stability and photostability, can be perfectly compatible with various cosmetic raw materials such as water-based emulsifiers, humectants, plant extracts and functional active substances, no precipitation or delamination, no oxidation, discoloration or peculiar smell during long-term storage and normal processing, mild and non-irritating, non-sensitizing, non-comedogenic, no harmful impurities such as heavy metals, with low dermal absorption rate (only 0.26%), passed multiple skin safety tests and cosmetic raw material safety certifications, suitable for sensitive skin, oily acne-prone skin, dry skin and infant fragile skin, and is the core raw material for creating lightweight, oil-free, broad-spectrum and mild sunscreen cosmetic formulas, especially suitable for water-based sunscreen products and children's sun care products.

Key Benefits
