Using GC/MS and GC/Olfactmetry analysis, we identified two vinyl ketones such as 1-Octen-3-one (OEO) and cis-1, 5-Octadien-3-one (ODO) as key materials in axillary odor. OEO and ODO showed a strong metallic odor and low odor threshold. These two materials were occurred from the reaction of unsaturated long fatty acids in lipids and the iron ion in our body's metabolism. Then, it was recognized that Morus alba (Japanese name, Kuwa) extract, one of the plant extract, showed a very good effect to control the generation of these vinyl ketones due to its remarkable anti-oxidization effects.

This study was performed to evaluate a deodorant body wash with 1.0 wt% of triclosan and 0.4 wt% of bamboo salt, which have an inhibitory effect on axillary malodor. In this studies, in vitro antibacterial study and the clinical study, which was designed by randomized assignment, double-blind and cross-over, were performed. In the antibacterial study, test sample, which was body wash having 1.0 wt% of triclosan and 0.4 wt% of bamboo salt, have a potent antibacterial effect on Corynebacterium glutamicum, Corynebacterium xerosis, Corynebacterium jeikeium. In the clinical study, test sample has a potent and significant deodorizing effect on axillary malodor and an antibacterial efficacy. And its efficacy was maintained for 9 h at least. There was no side effect during the period of clinical study. Consequently, body wash, containing 1.0 wt% of triclosan and 0.4 wt% of bamboo salt, has the effectiveness and the safety about axillary malodor reduction.

Background : Axillary osmidrosis is characterized by an unpleasant odor, profuse sweating, and in some instances, staining of clothes that may socially and psychologically impair affected individuals. Various types of surgical procedures have been developed for the treatment of axillary osmidrosis. This study was undertaken to evaluate the effectiveness of subcutaneous pulsed neodymium: yttrium-aluminum-garnet (Nd-YAG) laser treatment for the treatment of axillary osmidrosis. Methods : Twenty-nine patients with axillary osmidrosis were included in this study. Patients were categorized according to the results of an axillary malodor grading system, and a subcutaneous pulsed Nd-YAG laser was applied to all patients. The treatment area for the appropriate distribution of laser energy was determined using the iodine starch test (Minor's test) against a grid pattern composed of $2{\times}2cm$ squares. The endpoint of exposure was 300 to 500 J for each grid, depending on the preoperative evaluation results. The results were evaluated by measurement of axillary malodor both pre- and postoperatively using the grading system and iodine starch test. Results : The average follow-up period was 12.8 months. Nineteen patients had a fair-to-good result and ten patients had poor results. The postoperative Minor's test demonstrated that there were remarkable improvements for patients with mild to moderate symptoms. Complications including superficial second degree burns (n=3) were treated in a conservative manner. A deep second degree burn (n=1) was treated by a surgical procedure. Conclusions : Subcutaneous pulsed Nd-YAG laser has many advantages and is an effective noninvasive treatment for mild to moderate axillary osmidrosis.

We have developed a high performance powder, which has a quenching efficacy not only for short-chain fatty acids and amines, but also for vinyl ketones (l-octen-3-one, cis-l,5-octadien-3-one), newly found as other key compounds in axillary malodor. By investigating various powders known to have a quenching efficacy, we finally developed a highly porous silica bead containing magnesium oxide. We found that the superior deodorant effect performed by this powder was the result of multiple effects due to both an excellent physical adsorption capability from its high porosity and a specific adsorption of vinyl ketones by magnesium in the powder. An antiperspirant formulation containing both this powder and a Morus alba extract showed good efficacy as a deodorant.
