ISP: new broad spectrum UV absorber
ISP Personal Care has added a new sun care UV filter to its portfolio that has been designed to provide broad spectrum skin protection against damage caused by exposure to the sun. Called Escalol S, the new ingredient offers protection from both the UVA and UVB ranges of the light spectrum in a single ingredient. The ingredient is highly photostable, assuring effective and long-lasting protection against UVA radiation. Escalol S can 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 result in longer-lasting UVA protection. This broad spectrum functionality and synergistic effect will allow Escalol S to act as a ‘keystone’ for the broad range of ingredients that make up an effective sun care formulation. ISP has licensed the technology for bis-resorcinyl-triazine from BASF.
According to Philip Strenger, Senior Vice President - EMEA for ISP, the license with BASF will allow ISP to produce Escalol S and to market it worldwide. “HydroxyPhenylTriazine chemistry has been approved for use in Europe and elsewhere for several years, and ISP will offer this material to our customers in the EU immediately,” he said. “When the ingredient is approved by the United States Food and Drug Administration (USFDA) we will market Escalol S in the USA as well,” he added. It is expected that when the ingredient is approved and the new USFDA monograph on sunscreens is published, Escalol S will offer sunscreen formulators the opportunity to market sun care products that provide a ‘four star’ rating for UVA protection in the United States – the highest level of protection under the new UVA protection rating system.
According to James A. Mish, Vice President and General Manager of ISP Personal Care, the technology represented in Escalol S responds to a consumer market that is increasingly concerned with the consequences of prolonged exposure to the sun, in an ingredient that meets the formulating and sensory requirements of the personal care industry. “More than ever, consumers and regulatory agencies are focused on the potential damage of UVA radiation to skin and to overall health. The major trend in sun protection is toward broad spectrum protection – from both UVA and UVB radiation. Escalol S, based on HydroxyPhenylTriazine chemistry, is a highly efficient technology that can form the keystone of the UV filter package in sunscreen products,” he said. “Escalol S offers some great synergies with existing organic and inorganic UV filters, and because it is broad spectrum, we can imagine a situation where it is included in sun care protection regimens in every type of sun care and skin care product. Cosmetically-elegant, easy to formulate and efficient, Escalol S is an ideal starting point upon which to build UV protection packages,” he added.
Manufacturing in Columbus, Ohio
Escalol S will be manufactured in the US by ISP at its Fine Chemicals facility in Columbus, Ohio, where it has produced fine chemicals, pharmaceutical intermediates and finished active pharmaceutical ingredients (APIs) for many years. This cGMP facility is routinely audited by the FDA and leading pharmaceutical companies with excellent results. The agreement with BASF provides ISP with the necessary process know-how, registrations and patent rights for the manufacture of Escalol S.
Technology for a broad range of end uses
Escalol S is easily formulated, compatible with most cosmetics ingredients and has a cosmetically elegant feel. This makes it ideal for a broad range of sun and skin care products including long-lasting sunscreens in aerosol, spray, lotion and gel forms, anti-aging/firming creams and day creams, multipurpose products, such as bronzing agents and insect repellants, and decorative cosmetics with SPF claims.
According to Mr. Mish, the addition of Escalol S to ISP’s sun care product portfolio will allow the company to work more closely with the manufacturers of next generation sun protection products. “Escalol S is an exciting addition to ISP’s UV filter portfolio because of its broad spectrum protection and its synergistic effects with other UV filters. This puts ISP in a position of being able to bring a broad range of technology – including UV filters, solubilizers and film formers – to the makers of sun care products. With our formulation background and expertise, we feel that we can enhance our status as one of the world’s leading suppliers to the sun care market,” he added.
