Store in a tightly closed container in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage. This substance is stable under recommended storage conditions. 4-Methyloctanoic Acid is incompatible with strong oxidizing agents as well as strong bases. This chemical causes severe skin burns and eye damage.

4-Methyloctanoic acid has a fatty, musty, plastic odor. This compound is also reported to have a goat, costus, mutton odor

Physical properties

4-Methyloctanoic acid is one of the acids mainly responsible for the so-called "soo" odour of mutton. The analogue 4-Ethyloctanoic acid (found in Virginia tobacco and Costus root oil) also has a related goaty odor; this analog has the lowest threshold of all the fatty acids at 1.8 ppb. 4-Methyloctanoic acid is used in flavours for cheese, meat, tobacco and (possibly) fish. Normal use levels in finished consumer product: up to 3 ppm.

Occurrence

Reported found in cooked mutton fat, raw and cooked mutton, lamb, and blue, cheddar, parmesan, provolone and romano cheeses

Aroma threshold values

Aroma characteristics at 1.0% in PG: waxy, fatty, meaty, reheated beef-like with a slightly lactonic cheesy nuance

Taste threshold values

Taste characteristics at 10 ppm: fatty, waxy, creamy and lactonic with a satiating fatty mouthfeel and metallic nuances.

General Description

4-Methyloctanoic acid is a branched fatty acid commonly used in the flavor and fragrance industries. This compound gives sweaty and goaty flavors to the mutton meat and goat′s milk cheese, respectively.
