375. Great New Laundry Soap Discovery! PMC's OSO, 1957

As one knows Philippine Manufacturing Company (PMC) started as early as 1908, under the name Manila Refining Co. It capitalized on the rich coconut industry of the country, to give us edible products like “Purico”, an early vegetable oil-based shortening. When Procter and Gamble acquired it in 1935, the company beefed up its coconut oil-based product portfolio to include laundry detergent bars, with the introduction of PERLA  in 1949.

The next decade saw PMC expanding its detergent line. In 1951, it came up with dirt-fighting “Luto”, and in  1957, it launched OSO.

OSO was heralded as “a great new soap discovery”, with a promise that it “washes better than any other soap”—a bold superlative claim, at that time. It was a product of a “new process” that made the soap purer and brighter. Thus, OSO had a 3-way advantage: longer-lasting suds, greater economy, and more fragrant clothes.

 Subsequent ads positioned it as “the whitest soap, for the whitest wash”. Even with this, OSO did not last the 50s decade.  After all, P&G already had 3 detergent bars at that time, and the differentiation was not delineated at that time. The best performer was PERLA, and consumers have also began discovering that it was also ideal for white clothes, as it was not only effective, but gentle. OSO was eased out towards the end of the 50s decade; LUTO would also be dropped. PMC decided put its marketing resources behind PERLA, a move that proved to be wise, as the iconic soap bar continue to exist to this day.
