Chief ingredients in Persil washing powder besides soap were sodium PERborate and sodium SILicate (get it? "PerSil..".
https://en.wikipedia.org/wiki/Persil#History
Sodium metasilicate along with some other silicates are rather good water conditioners. As with all soap based products one simply used enough product to maintain a rich layer of suds. Since Persil contained water softeners one dosed according to soil levels and water hardness.
Then yes, of course there was all that hot or boiling water for washing and or first one or two rinses.
Right up until and through 1970's hospitals and others doing healthcare laundry in UK used nothing but soap and sodium metasilicate for doing things fouled by blood and other fluids or secretions. Results were quite good to excellent. Then again they were also washing at temps at or near 95 degrees C.
Getting around hard water and using soap for wash day....
In Germany and some other markets Henkel devised the wash day trinity: Henko (a washing soda based pre-soak), Persil (washing powder) and Sil (a perborate based rinse agent that went in first hot/boil rinse).

Bringing this back on home....
After P&G launched Tide detergent in 1940's nearly every soap based wash day product was threatened. This included until then Lever Bros "Rinso". They did their best to reverse declining sales of brand including introducing "blue" Rinso which was a detergent, but nothing really helped.
In 1952 Lever Bros. launched "Surf" (in UK market) and Sunil in Netherlands, Germany and other markets which was a detergent.
Because it was a detergent Sunil/Surf like Tide and others did away with issues caused by hard water on wash day.
In this German advert the mother who has not heard nor used Sunil learns its benefits from another housewife who knows what she's talking about. First housewife asks about "soaking" and boil rinsing (referring to Henkel's wash day trinity), with other housewife telling her none of that was necessary. Just into kochewashe tub, bring to boil, etc....
In this other commercial for Sunil a housewife is schooled by her laundress in virtues of Sunil...
Lever Bros. got jump on Henkel by introducing Sunil/Surf in 1952. Henkel wouldn't bring out a detergent version of Persil until 1959 (Persil 59...)
Notice packaging for German "Sunil" wasn't that much different than OMO sold in UK and elsewhere.

Back to hard water and soap on wash day..
While Lever Bros was content to introduce detergents such as Sunil, their top selling wash day product in UK, Persil, would remain soap based well into 1960's and beyond. Lever Bros over years tinkered with formulas for Persil doing things such as adding phosphates, using different types/formulas of soaps, creating versions for hard and soft water, adding washer protection agents including ingredients to prevent limescale on heater elements, etc... All this culminated with introduction of "new improved" Persil in 1968 which was still a soap based product.
Hi, as the title says, I am creating this thread about the history of Persil, the detergent brand, as I would like to know more about Persil and also about the history of the brand. I hope this thread also educates others as well. So please can you share anything you know about Persil and I...
