Triethanolamine Phenylbenzimidazole Sulfonate-CAS 10020-01-6
Triethanolamine Phenylbenzimidazole Sulfonate, commercially known as TEA-PBS, is a high-purity cosmetic grade water-soluble UVB filter refined by advanced sulfonation, neutralization, purification and recrystallization technology.
It is a lightweight and widely used core functional raw material in the global high-end sunscreen and personal care industry, derived from phenylbenzimidazole sulfonic acid and neutralized with triethanolamine to improve its water solubility and compatibility with water-based cosmetic formulas.
Different from traditional oil-soluble UVB filters with heavy texture, poor compatibility with water-based formulas and sticky skin feel, ordinary water-soluble UVB filters with narrow protection range and poor photostability, and common broad-spectrum sunscreen agents with high irritation, TEA-PBS has a unique sulfonic acid triethanolamine salt structure, which is a typical lightweight water-soluble UVB absorber with partial UVA-II protection.
It can efficiently absorb ultraviolet rays in the 280-320nm UVB band, with a peak absorption at 306nm, and also has a certain absorption effect on 320-340nm UVA-II band, forming a thin, breathable and non-sticky protective barrier on the skin surface to effectively resist UV radiation damage, prevent skin sunburn, redness, itching 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 lightweight care, it not only has excellent UVB absorption capacity, but also can act as a synergist for other water-soluble and oil-soluble UV filters (such as Zinc Oxide, Titanium Dioxide, Octocrylene and Avobenzone), improving the photostability and SPF value of other sunscreen agents, avoiding their decomposition under sunlight, and extending the effective protection time of sunscreen products, especially for water-based sunscreen formulations and sensitive skin care products.
It is white crystalline powder with excellent water solubility, can be quickly dissolved in water to form a transparent solution, can be evenly dispersed in water-based and oil-in-water cosmetic formulas, has good compatibility with various cosmetic raw materials such as hydrophilic emulsifiers, plant extracts, humectants and functional active substances, will not cause heavy, greasy or sticky feeling on the skin, and will not leave white residue on the skin surface, bringing a refreshing, smooth and comfortable use experience.
The product has excellent chemical stability and photostability, can be perfectly compatible with various cosmetic raw materials, no precipitation or delamination, no oxidation, discoloration or peculiar smell during long-term storage and normal processing, ultra-mild and non-irritating, non-sensitizing, non-comedogenic, no harmful impurities such as heavy metals, passed multiple skin safety tests (including sensitive skin patch test) and cosmetic raw material safety certifications, suitable for sensitive skin, oily skin, combination skin, infant fragile skin and maternal skin, and is the core raw material for creating refreshing, non-greasy and mild sunscreen cosmetic formulas, especially suitable for water-based, oil-in-water lightweight sunscreen products, spray-type sunscreens and summer oil-control sunscreen products.
Key Benefits
