Documented Uses

• ... plant growth regulator ... of tobacco.
• Perfumery, cosmetics, organic synthesis, solvent manufacture of high-boiling esters, antifoaming agent, flavoring agent.
• Mixtures of 1-hexanol and 1-octanol serve as frothing agents (bubbling promoters) in flotation, e.g., of coal. Large amounts are added to aqueous drilling muds to prevent frothing during drilling for oil and gas.
