International Specialty Products (ISP) has introduced a UV absorber for broad-spectrum sun care products. Escalol S (INCI: Not Provided) is based on hydroxyphenyltriazine chemistry to serve as a UV filter for UVA and UVB protection in beach and daily wear products.
The filter reportedly is highly photostable, assuring effective and long-lasting protection against UVA radiation. The filter is said to boost the performance and the stability of other commonly used UV filters, creating synergies that offer higher SPF ratings for UVB radiation and photostability that results in longer-lasting UVA protection.
To produce and market the filter, ISP licensed the technology for bis-resorcinyl-triazine from BASF. Hydroxyphenyltriazine chemistry has been approved for use in Europe and elsewhere for several years, and ISP will offer this filter immediately to Europe, with plans to offer it in the United States when approved by the US Food and Drug Administration (FDA).
The company reports that when the ingredient is approved and the new FDA monograph on sunscreens is published, the filter will offer sunscreen formulators the opportunity to market sun care products that provide the FDA's four star rating for UVA protection in the United States.
The filter is synergistic with both organic and inorganic UV filters, according to the company. In addition, the UV filter is easily incorporated into formulations and allows for elegant formulations.
