Applications
Acids and esters are a broad and versatile class of chemicals with wide applications across industries. They are used as solvents in coatings, inks, and cleaning formulations; serve as intermediates and building blocks in polymer and plasticizer production; play roles as fragrance and flavor compounds in the fragrance and flavor industries; in cosmetics and personal care they are used as solvents, emollients, and formulation additives; and as intermediates or active ingredients in pharmaceutical synthesis. These roles reflect the versatility of acids and esters, enabling activities from polymer manufacturing to consumer-product formulations; use is subject to local regulations and formulation limits.
