What changed

The United States Patent and Trademark Office (USPTO) has granted patent US12582591B2, titled 'Increased solubilization of ethylhexyl triazone,' to DSM IP ASSETS B.V. The patent covers a cosmetic composition that includes an ester of a fatty acid and dextrin, a mixture of branched and linear saturated C15-C19 fatty acids, and a specific UV-filter. The primary innovation highlighted is the enhanced solubilization of the UV-filter, which allows for the creation of cosmetic products with a higher Sun Protection Factor (SPF) and greater absorbance of harmful UV light.

This patent grant signifies the USPTO's recognition of novel intellectual property in the cosmetic and pharmaceutical sectors. For companies operating in this space, particularly those involved in the development and manufacturing of sunscreens and other UV-protective cosmetic products, this patent may impact their freedom to operate and product development strategies. While this is a patent grant and not a regulatory rule imposing direct compliance obligations, it establishes exclusive rights for the assignee, potentially requiring licensing or alternative formulation strategies for competitors.

Abstract

The present invention relates to cosmetic composition comprising an ester of a fatty acid and dextrin, a mixture of branched and linear saturated C15-C19, wherein said mixture comprised primarily branched saturated C15-C19, and a UV-filter of the formula (I) This cosmetic composition allows a high amount of the UV-filter of the formula (I) to be solubilized which leads to compositions having a very high absorbance of harmful UV light, i.e. to compositions having a high Sun Protection Factor (SPF).
