## Midlife body odor starts
Women over 40 notice a faint musty scent that soap and water can’t eliminate.
## 2-nonenal causes age odor
2-nonenal, a compound from oxidized skin fats, creates musty, grassy or dusty body odor.
## Persimmon soap targets odor
Persimmons contain tannins that interact with odor compounds instead of masking them with fragrance.
## Persimmon soap benefits skin
Japanese deodorizing products focus on addressing odor at cleansing stage with minimal fragrance.
## 2001 study finds 2-nonenal
A 2001 study detected 2-nonenal only in subjects 40 years or older.
## 2012 study shows reduction
A 2012 Japanese study reported reduced 2-nonenal and odor after four weeks of persimmon soap use.
## Persimmon soap helps with age odor
Persimmon soap is a plausible option for age-related body odor but not a proven cure.
## Key takeaway

2-nonenal, a compound formed from oxidized skin fats, causes musty body odor in older adults that persimmon soap can target through tannins.
