Wash Away "Ageing Odour" at the Source

After 50, your skin produces a compound called 2-nonenal that ordinary soap cannot remove. Sawumi's fermented persimmon tannin neutralises it, instead of perfuming over it. A centuries-old Japanese ritual, made for British bathrooms.

The Problem Nobody Mentions

Is It On Your Pillowcase?

You can't smell 2-nonenal on yourself. Your nose adapts within minutes. But the signs are always there:

1

Yellowish marks on pillows and collars that never fully wash out, whatever detergent you use.

2

A "greasy, grassy" note that lingers behind the ears and on the chest, even straight after a shower.

3

Loved ones sitting a little further away. And nobody ever says why.

Why It Works

Neutralised. Not Masked.

Deodorants and perfumes layer scent on top of nonenal. Fermented persimmon tannin (kakishibu) binds to the molecule and breaks it down on contact. The Japanese have used it for centuries. We pressed it into a bar.

Lather

Warm water, rich amber lather. Chest, neck, back, behind the ears.

Neutralise

Kaki tannin binds to 2-nonenal and dismantles it at the source.

Fresh Again

Most customers notice the pillowcase difference within 3 to 7 days.

The Proof Is In The Wash

One Bar. Seven Days.

Don't take our word for it. Take the pillowcase test: change nothing else, wash with Sawumi daily, and look at your linen after a week.

The pillowcase test. 2-nonenal builds up in fabric as a yellowish, greasy film that laundry alone can't beat. When it stops arriving, your linen finally stays fresh.

The collar test. That ring that never washes out isn't dirt. It's oxidised skin lipids. Neutralise them at the source and it stops coming back.

My daughter said "Mum, you smell lovely"

First time in years. I cried in the kitchen. Nobody tells you how much the small things matter at my age.

The pillowcases speak for themselves

Bought it for my husband after 40 years of marriage. He now uses it more religiously than I do. The pillowcase test does not lie.

Sceptical at first, it's soap after all

But within a week the difference on my collars was undeniable. It's the real kaki extract, I checked the label.

Husband and I both use it now

Started as mine, now there are two in the shower. The spare room doesn't smell of "grandad's house" when guests stay.

Questions, Answered

What exactly is "ageing odour"?
From around age 50, skin lipids oxidise into a compound called 2-nonenal. It has a greasy, grassy scent, clings to skin and fabric, and ordinary surfactants can't break it down. It's chemistry, not hygiene.
How is Sawumi different from normal soap?
Sawumi contains real fermented persimmon tannin (Diospyros Kaki Fruit Extract, it's on the label). The tannin binds to 2-nonenal and neutralises it on contact instead of masking it with fragrance.
How long does one bar last?
Used daily on chest, neck, back and behind the ears, one 100g bar lasts about a month.
When will I notice a difference?
Most customers report the pillowcase difference within 3 to 7 days of daily use.
Is it suitable for sensitive over-50 skin?
Yes. The formula is fragrance-light, pH-balanced and gentle enough for the face. If in doubt, patch-test on the inner arm first.
What if it doesn't work for me?
Then it's free. Email us within 30 days of delivery and we refund in full. You don't even need to post anything back.
