The origin of the P&G logo can be traced back to the shipping business along the Ohio River and other Midwestern rivers more than a hundred years ago. Illiterate longshoremen of the time identified P&G's star candles by drawing a crude plus sign on the cargo box, thus letting ship owners know whose product they were handling and where it was being shipped. Later, P&G began to attach marking stars to each container, and some artistic dockworkers drew circles to surround the stars, and also added some other decorations, such as the face of the moon— —That was a pretty popular image at the time. Pamp;G then further processed it and turned it into a more exquisite Moon Man logo. If someone wants to erase the moon face on the P&G product packaging box, some wholesalers will object, because they only trust those goods with the complete P&G logo.

William Parrott, the company's founder, thought this was an attractive logo, and he suggested that the number of stars be set at 13 to represent the stars on the American flag at that time. In 1882, this improved logo was registered as a trademark. Since then, it has appeared on all P&G products and has become increasingly popular. But in the 1980s, this logo caused a huge controversy. There were rumors at the time that P&G's logo was a symbol of the devil. This man's curly beard hides the devil number 666, and the meaning of the 13 stars is considered to be a reference to the Bible "The saint is clothed with the sun, with the moon under her feet, and the 12 stars turn into a bright crown." sun, with the moon under her feet, and on her head a crown of 12 stars". The number "666" is considered by Christians to be the number of the beast and represents evil. At the same time, there were rumors that Procter & Gamble was taken over by the then cult organization The Church of the Moon. In 1911, Procter & Gamble made detailed changes to the logo, removing the curly beard. But the rumors about P&G, the Church of the Moon, and the Church of Demons have not subsided. Two years later, P&G stopped using the star and moon logo and adopted the P&G letter logo, which is still in use today. But in China and Japan, P&G's star and moon logo did not completely stop public use until 2002.
