Hey, old fart! You stink!

I can smell your feet a mile away! (Smile away, smile away…)

I compute on my couch naked with a towel underneath to catch my sweat. My towel really stinks after three days. If towel stinks, I must stink.

The trouble is that this old age chemical is wax-based rather than composed of body oils. That makes it really hard to wash off.

Did some research into this and came up with persimmon. Japanese pick green persimmons and ferment them for three years. These tannins are used mostly for dyes. But I want to try making them into a body scrub with Castile soap.

Don’t bother looking. I’ve only found one company that sells the liquid tannin and will be stocking powdered by end of summer. Canadian company, Maiwa.

Nonenal (2-Nonenal) is a chemical compound produced when fatty acids on the skin oxidize. Widely known as the scientific cause of "aging odor" or "old person smell," it typically begins to develop around age 40 and has a distinct greasy, grassy, or musty scent.

Why It Happens

• Biochemical Change: As people age, the skin's lipid composition changes, resulting in more Omega-7 unsaturated fatty acids. Simultaneously, the body's natural antioxidant defenses decrease, causing these fatty acids to oxidize and break down into Nonenal. [1, 2, 3, 4]

• Not a Hygiene Issue: Nonenal is water-insoluble and grease-based. Because it is a lipid compound, traditional soaps and scrubbing do not wash it away. [1, 2, 3, 4]

How to Manage and Eliminate It

Because ordinary soaps are ineffective against Nonenal, a targeted approach is required to neutralize the molecule and prevent its accumulation: [1]

• Use Persimmon Extract: Soaps or body washes formulated with Persimmon Tannin are highly effective. The molecular structure of the tannin binds to and breaks down the Nonenal molecule, neutralizing the odor rather than just masking it. [1, 2]

• Focus on Problem Areas: The odor is most heavily concentrated where sebaceous glands are dense: the back of the neck, behind the ears, the chest, and the upper back. [1]

• Target Clothing and Bedding: Nonenal easily transfers to and sticks to fabrics. Washing contaminated items with oxygen bleach or enzyme-based detergents and drying them in direct sunlight helps break down the odor. [1, 2, 3]

• Adjust Diet: Reducing the intake of saturated fats, fried foods, and processed meats lowers the production of fatty acids on the skin. Consuming antioxidant-rich foods, such as berries, leafy greens, and green tea, helps reduce oxidative stress

[OIL-FREE] Oil-free persimmon body wash recipe

An oil-free persimmon body wash rinses completely clean without leaving a residue, making it ideal for oily or acne-prone skin while retaining full deodorizing power. Because it lacks heavy oils, this formula relies on vegetable glycerin to keep the skin hydrated without clogging pores. [1]

Ingredients

• 1 cup Liquid Castile Soap (unscented)

• 2 tbsp Aloe Vera Gel (pure, inner-leaf gel for soothing hydration)

• 1 tbsp Vegetable Glycerin (acts as a humectant to draw moisture to the skin)

• 1 to 2 tsp Liquid Persimmon Extract (Kakishibu)

• 10 drops Essential Oils (Peppermint or eucalyptus provides a crisp, oil-free cooling sensation) [1, 2, 3]

Instructions

1. Blend Hydrators: In a clean mixing bowl, whisk the aloe vera gel and vegetable glycerin together until completely smooth and unified.

2. Incorporate Extract: Stir the liquid persimmon extract directly into the aloe and glycerin mixture.

3. Combine with Soap: Slowly pour in the liquid castile soap. Stir gently with a spoon to mix the ingredients thoroughly without creating unwanted foam.

4. Bottle: Transfer the mixture into a clean pump bottle or soap dispenser. [1, 2, 3, 4, 5]

Usage & Storage

Shake the bottle gently before each use, as natural ingredients can settle over time. Since this recipe utilizes shelf-stable extracts and aloe gel, it can be stored right in your shower and will remain fresh for up to 6 months.

[OIL] Persimmon extract body wash recipe

Using shelf-stable liquid persimmon extract (Kakishibu) allows you to create a long-lasting, highly effective deodorizing body wash that breaks down tough body odors like nonenal. Unlike fresh fruit puree, a recipe using botanical extract does not require refrigeration and will last for months. [1, 2, 3, 4]

Ingredients

• 1 cup Liquid Castile Soap (like Dr. Bronner's Unscented available on Amazon)

• 1 to 2 tsp Liquid Persimmon Extract (Kakishibu) or 1/2 tsp Japanese Persimmon Extract Powder

• 1 tbsp Vegetable Glycerin (for a richer lather and hydration)

• 1 tsp Sweet Almond Oil or Jojoba Oil (to prevent skin dryness)

• 10-15 drops Essential Oils (Tea tree, eucalyptus, or Japanese yuzu complement the formula well) [1, 2, 3, 4, 5]

Instructions

1. Dissolve (if using powder): If you are using persimmon extract powder instead of liquid, mix the powder thoroughly into the vegetable glycerin first to ensure it dissolves completely without clumping. [1]

2. Combine Base and Oils: In a clean mixing bowl or glass measuring cup, gently stir together the liquid castile soap, vegetable glycerin, and your chosen carrier oil. [1]

3. Add the Extract: Stir in the liquid persimmon extract (or your dissolved powder mix). [1, 2]

4. Scent and Bottle: Drop in your chosen essential oils and stir slowly to prevent generating excess foam. Pour the finished liquid into a clean soap dispenser.

Why Extract Works Better

Commercial and premium options like Mirai Clinical's Purifying & Deodorizing Body Wash exclusively use Japanese persimmon extract because the condensed kakishibu tannins specifically bind to and eliminate lipid-based odors like nonenal. Regular soaps only wash over these oxidized fatty acids without breaking them down.

Some old people smell really bad - you probably just need to shower with soap more often

rather than relying on elaborate washing regimes once a month

Just a bathtub and some bath salts should do the job. I would also start with exercise, a healthy diet and staying properly hydrated. That is likely to do more for body odor and overall health than looking for another miracle product.

I never noticed old people smelling more until they lose the capacity to wash themselves.

I've always been a little dirtier than most I think. I'm outdoors all the time and like to take quick showers often. I smell nice but hard to reach areas over time start to get dirty. I now go for quality showers vs countless showers. I made the change when the wife laughed at my side of the bed with the sheets removed. It wasn't funny at all IMO. I bought a new mattress and so far so good.

It's true they smell like sour pee and unwiped arse cracks.

God life is brutal at times.

Shower and change your masturbate towel daily will sort that.

I routinely have three showers a day, four when exercising.

I'd like to find our more. What do you mean by "quality showers"? We only have "cold" water.

Do all that. But who takes baths in Thailand?!? Yes, we have a bathtub. Great for rinsing cloths and brooms.

I do like a hot bath. I have one when to go to nice, seriously air-conditioned hotels!

Longer showers and I scrub more - TMI :)

I don't think I "stink really bad". But that towel I sit on for 7-9 hours every day stinks really bad. So it must be coming off me.

I think, most old people smell bad for other reasons than just poor hygiene or changed skin oils.

Very often, the smell is quite typical, and can be put in three groups: people with liver problems smell like ammonia, people with kidney problems smell like urine and old fish and diabetic people smell like acetone.

I fell, for a good time, in the kidney problems category, and it was actually not pretty, while all the time thinking that my wife was a bit of a drama queen (she called it "horrible to the point of wanting to die when I am in the room", make of that what you will).

Sometimes, all this can be reversed with an improved diet, getting rid of those extra kilos, drinking enough, and not stressing and poisoning the body on a regular basis (yes, I am talking about alcohol, especially in an dehydrated oldy).

With medical intervention for my kidney, the smell has reduced to the normal smell of "unwashed farang", or so I am told.

With regard to nonenal excretion; I do not suffer from it (yet?), but from what I heard, CoQ10 (every person should take this, anyway), and anti-oxidant supplements like astaxanthin or fucoxanthin help (they accumulate in the skin, preventing lipid breakdown there). This is the supplementation from the inside, topical help from the outside would be the persimmon topical mentioned in the OP, or one with green tea, or a combination of both would also help.

I must admit I take great care with how I smell, body and breath. I work with students 7-8 years old. They are brutally honest and if you stink they let you know.

I have a bathtub on my balcony and fill it with fresh, colder water from the well during the warm season. In the cold season, I fill it with hot water and sit there soaking a few times a week.

It also helps to stay active a couple of times a day and take short showers.

Omg, I'm surrounded by you guys 🤢

Shower twice a day, use deodorant, and wear clean clothes. This is not rocket science.

Oh dear, you live alone I reckon?

Are there really people out there who don't change towels and underwear every day? I do it with my bedsheets also.

Sorry, to tell you, but a bit more hygiene is not a mistake 🤣

Perhaps a visit to the local soapy is in order……

Wow. You wear underwear?

My skin smells like cannabinoids, the mosquitos tend to lay around and eat Cheetos after they smell me. 😁

Making your own soap is Tyler Durden level , not necessary

Simple Thailand routine for Oldsters

Daily: Skinoxy Body Wash (pH 5.5) or Watsons Softening Cream body wash

2–3×/week: Watsons Papaya Vitamin C Body Cleaner

Optional: Mario Badescu AHA Botanical Body Soap or Naturium Glycolic Acid Body Wash (AHA - alpha hydroxy acids)

It's a health issue not age.

I'm 75 and i smell the same... Wonderful! I've got references!

or out of you maybe ?

The pores in skin open in hot water and stay closed in cold water. Fit a water heater on your shower. I have 8Kw heaters but 6Kw is enough and even 4Kw is better than nothing, especially in January.

Tip: finish your lovely warm/hot shower with two minutes of cool water to cool your core temperature down otherwise you'll need another shower five minutes later.

It's not difficult , Just respect people's personal space , Whenever possible I avoid getting too close to people, I have never experienced the "old persons smell" that has been mentioned here.

So Just stop getting too close to them, it's a bit weird and they don't like it

Two minutes of a cold shower would have absolutely no cooling effect on ones core body temperature. if anything it would have the opposite result

from AI

The sudden temperature drop triggers your sympathetic nervous system, inducing "cold shock". Your body immediately begins shivering or increasing non-shivering thermogenesis to actively generate internal heat. This metabolic spike often cancels out the external cooling effect of the water.
