ABSTRACT:
A process to manufacture 4-methoxybenzoic acid from anethole. This raw material can be obtained from a variety of plant materials and thus offers a renewable alternative to fossil raw materials. Another aspect of the present invention is the use of 4-methoxybenzoic acid gained from vegetal anethole as raw material in cosmetic and dermatologic products and/or aroma components in foodstuffs.
