Nonyl acid is a by-product obtained during the hydrolysis of lauric oil, coconut oil or nutmeg oil to produce lauric acid. It is mainly used for the production of decanoate products. The esters of this acid are used as fragrances, humectants, plasticizers and food additives, etc. 

Nonanoic acid is a medium-length carbon chain saturated fatty acid. It is present in small amounts in milk and goat milk, and has relatively high content in tropical oils such as coconut oil (with a nonanoic acid content of approximately 8%) and palm kernel oil (with a nonanoic acid content of approximately 9%). Nonanoic acid and its esters are mainly used in the fields of food, plastic additives, medicine, chemical pesticides, chemical industry, and aviation, and can be used as flavoring agents for dairy products, rum, brandy, etc., food additives, lubricants, wetting agents, plasticizers, foaming agents, rust inhibitors, polymer modifiers, special oils for high and low temperatures, aviation oil, etc. The application fields are extensive and the market prospects are very optimistic. 

Used in the synthesis of fragrances, spices and medicines

Defoamer; According to GB 2760-96, it is stipulated as a permitted heavy-duty sumbol aroma ingredient. It is mainly used in dairy products, rum, brandy, liqueurs, etc. as type aroma essences for manufacturing ester compounds, serving as fruit flavoring agents. It is also a chemical synthetic intermediate.

It is mainly used for the production of decanoic acid ester products, and the ester compounds are used as flavoring agents, wetting agents, plasticizers, and food additives, etc.
