Product Application Of Octanoic acid CAS#124-07-2
Octanoic acid is widely applied in various fields, It is an antimicrobial pesticide used as a food contact surface sanitizer in commercial food handling establishments on dairy equipment, food processing equipment, breweries, wineries, and beverage processing plants. In addition, caprylic acid is used as an algaecide, bactericide, and fungicide in nurseries, greenhouses, garden centers, and interiorscapes on ornamentals. Products containing caprylic acid are formulated as soluble concentrate/liquids and ready-to-use liquids.
Caprylic acid is also used in the treatment of some bacterial infections. Due to its relatively short chain length it has no difficulty in penetrating fatty cell wall membranes, hence its effectiveness in combating certain lipid-coated bacteria, such as Staphylococcus aureus and various species of Streptococcus.
Octanoic acid is used commercially in the production of esters used in perfumery and also in the manufacture of dyes.
Some studies have shown that Caprylic acid is effective to excess calorie burning taken as a dietary supplement, resulting in weigh loss.
