The war rationed fat away from soap. The synthetic substitute took over the market in seven years.
In 1913 the German company BASF launched the first commercially successful synthetic detergent.
It was called Nekal. It wasn’t invented because someone wanted better soap. It was invented because German chemistry was looking for new markets.
The year after, the First World War broke out. The British blockaded German ports. Fat was rationed — it was needed for food, ammunition, lubricants. Not for soap.
So German industry developed soap substitutes without fat. Entirely synthetic. Made from chemical building blocks — petroleum products, alkylbenzenes, sulfonates.
It wasn’t a revolution. It was a shortage.
When the war ended, the technology was mature. Procter and Gamble launched the synthetic shampoo Drene in 1934. It washed without soap. In 1946 P&G launched Tide. The world’s first heavy-duty synthetic detergent. It washed clothes clean in hard water, where traditional soap left residue.
Tide sold out as fast as P&G could produce it.
In 1953 — only seven years later — synthetic detergents outsold traditional soap for the first time in the USA.
Seven years.
It had taken soap 4,800 years to reach that point. A synthetic substitute took over the market in seven.
In 1955 Unilever launched Dove. It’s not soap. It’s a syndet bar — a synthetic detergent pressed into soap form, because consumers weren’t ready to let go of the familiar look. It looks like soap. It’s hard like soap. It’s not soap.
It kept going. SLS invented in the thirties. Triclosan added in 1972. Microplastic beads in the nineties. Every generation added a new layer that hadn’t existed before.
Soap was now the old choice. The old-fashioned choice. The grandmother’s choice.
That’s the world we were born into. Where “ordinary soap” sounds old-school. Where store shelves are full of bottles that don’t contain soap. Where people have to be reminded that fat plus lye plus water still works.
It’s seventy years old — this state of things. The Babylonians made soap for 4,800 years before there was an alternative. We’ve lived in the age of the alternative for seven decades.
It’s an experimental state we’re still in.
