The patent application (Publication Number: US20240001321A1) describes a delivery system that includes a solvent system, 1.5-10% of at least one polymer, 0.00025-0.75% of at least one enabler, and optionally at least one benefit agent that is different from the enabler. The solvent system is specified to be a hydroalcoholic one, with the alcohol component being a primary, secondary, or tertiary C1-C5 alcohol. The hydroalcoholic solvent system consists of ethanol in the range of 90-97% by weight and water in the range of 3-10% by weight. The benefit agent, when present, is in the range of 1-15% by weight and can include various components like fragrance, antioxidants, humectants, and more.

Furthermore, the delivery system includes specific details such as the molecular weight range of the polymer (25000 to 270000 Daltons), the log P value range of the enabler (-1.5 to 6), and the types of enablers that can be used, including carboxylic acids, amines, esters, phenols, and carbonyl compounds. The patent application also lists examples of specific compounds that fall under each category, such as acetic acid, triethyl amine, octyl methoxy cinnamate, BHT, and acetophenone. The delivery system aims to provide a versatile platform for incorporating various benefit agents while ensuring compatibility and efficacy in the delivery of these agents for different applications in the fields of personal care, cosmetics, pharmaceuticals, and more.
