2-Phenylbenzimidazole-5-sulfonic acid Usage

UV absorber

Water-Based Sunscreens: Highly effective water-soluble UVB absorbers, these are key ingredients in developing lightweight, non-greasy sunscreens and gels.

Daily Moisturizers: Widely used in day creams, sunscreens, and anti-aging lotions, these provide basic UV protection (SPF) while maintaining a lightweight feel on the skin.

Hair & Scalp Care: Used to protect hair from UV-induced fading and keratin damage, often added to leave-in conditioners and styling sprays.

Key Advantages

Excellent Water Solubility: Dissolves directly in the aqueous phase. Enables the development of completely oil-free or very low-oil products, providing a refreshing, lightweight feel.

Strong UVB Protection: Possesses an extremely high extinction factor, making it a highly effective additive for enhancing SPF.

Excellent Photostability: Highly stable under sunlight, resistant to degradation, and can be used as a co-stabilizer for other unstable sunscreen agents.

Improved Formulation Texture: Reduces the stickiness of oily sunscreen systems, increasing ease of application and absorption.
