The intriguing Soap Story Nobody Tells You.
Share
Most of us use soap every day without giving it a second thought. But the story of what goes into a bar of soap — and how it's made — is far more interesting than the label suggests.
A brief (and slightly grim) history
Soap has been around for thousands of years. The earliest known recipes, dating back to ancient Babylon, used animal fats and wood ash. For most of history, soap was made from tallow — rendered animal fat, often from cattle or sheep, sometimes from horses — combined with lye (an alkaline solution made from ash and water).
And here's the thing: it hasn't changed as much as you might think.
What's still in your supermarket soap
Tallow is still widely used in many mainstream commercial bar soaps. While some brands have transitioned to plant-based formulations, several household names on supermarket shelves continue to use animal fat as a primary ingredient.
Manufacturers rarely use the word "tallow" directly on the label. Instead, look for Sodium Tallowate — the chemical name for saponified tallow. If it's near the top of the ingredient list, animal fat is a primary component of that bar.
Beyond the tallow question, mass-produced soap also typically strips out the glycerin — a natural byproduct of the soap-making process that's brilliant for moisturising skin — and sells it separately to the cosmetics industry. Natural bars keep it in. That's the difference you feel.
Then there's the other kind
Small-batch, handcrafted natural soap is a different thing entirely. No synthetic detergents. No animal fat. No mystery preservatives. The glycerin stays in. And the ingredients actually mean something.
We recently came across the Scots Oat & Honey Soap Bar from Skye Natural Skincare — a small, independent producer based in Breakish on the Isle of Skye in the Scottish Highlands. It arrived as a taster gift with a recent order, and it stopped us in our tracks.
Beautifully sweet scented — honey and nectar, a delicate blend of Scottish wildflowers, ground oats, and a pleasing honeycomb top.
A proper cottage industry
And we mean that literally. Skye Natural Skincare is run by a founder who has built her business from a cottage in Breakish — directly opposite a thatched-roof cottage, to be precise — and has recently added an honesty caravan out front where locals and visitors can pick up products. It doesn't get more small-batch than that.
This is handmade soap in the truest sense: made by a real person, in a real place, in small quantities, with care. The kind of maker that's increasingly rare and absolutely worth supporting.
What's actually in it
The ingredient list reads like a masterclass in what soap should be:
- Sodium olivate (olive oil) — one of the oldest skincare ingredients in the world. Gentle, moisturising, and kind to sensitive skin.
- Sodium cocoate (coconut oil) — gives the bar its lather and cleansing power.
- Sodium shea butterate (shea butter) — rich and deeply nourishing. The reason this bar feels luxurious rather than just clean.
- Sodium castorate (castor oil) — boosts lather and helps bind the other oils together.
- Comfrey root powder — a traditional herbal ingredient with a long history of soothing irritated skin.
- Chamomile — calming and gentle, particularly good for sensitive or reactive skin.
- Annatto seed — a natural plant-based colourant giving the bar its warm golden tone.
- Blended essential oils — the source of that wildflower and honey fragrance.
No sodium tallowate. No synthetic detergents. No mystery preservatives. Just oils, botanicals, and essential oils — made in small batches, the way soap used to be made before the factories got involved.
One note: this bar is not suitable for vegans, as it contains honey.
Why it costs more — and why it's worth it
Natural soap costs more to make. Quality oils are more expensive than synthetic detergents or rendered fat. Small batches can't compete on price with factory production. But you're getting something fundamentally different: a bar that nourishes your skin rather than stripping it, made by a real person in a real place, with ingredients you can actually pronounce.
Sometimes the old ways — done properly — are simply better.
At Wilder & Fern we're drawn to things made with care, by real people, in real places. This soap is exactly that.
