Debate has raged for years over the real reason for the label on the Imperial Leather bar of soap.

The sticker is known for remaining secure even after weeks of use as the bar slowly wears away.

But now it's been revealed that the scratchy metallic label is actually a stand to stop the bar sticking to the soap dish.

One fascinated person on Reddit said it 'amazed' them how it managed to stay in place for so long, and was hit with a mind-blowing revelation about its real purpose.

A commenter explained that the sticker is meant to be used as a mini soap stand, and that the bar should be placed with the label facing down.

Imperial Leather confirmed to MailOnline that apart from brand identity the 'sticker on the top is for a long lasting bar and preventing mushiness'.

Redditors queried the real reason for the sticker on the Imperial Leather soap bar, which the brand has confirmed 'is for a long lasting bar and preventing mushiness'

Others were equally intrigued by the reason for the sticker as it was suggested that the main reason for it was to create a stand for the bar

'You have no idea how many times I’ve sat in the bath and stared at this sticker in amazement that it sticks to the soap ‘till the very end, Please enlighten me,' they asked.

Many discussed how nostalgic the soap was for them, reminiscing about seeing it in their grandparents bathrooms, whereas others were determined to uncover the truth.

'I don't know what glue they use, but I was always told that the sticker is meant to substitute for a soap stand, and should always be downwards,' revealed one.

'Well ****** me with a bar of soap! That makes perfect sense, I've been an imperial guy for years and never thought of that so I just went and 'flipped my soap' and it works, thanks!' one amazed reader responded.

Some suggested that the label itself was magnetic and helped it to stick.

'Older bathrooms used to sometimes have a chrome thing mysteriously fixed to the wall over the bath.

'It was magnetic and I think the the metal label on the soap stuck to it, thus removing the need for a gooey soap dish. Seemed like a good idea at the time,' said another.

Cussons & Sons eventually took over Bayley's of Bond Street, which included the acquisitions of original fragrances, in 1930 they launched their first Imperial Leather soap based on the scent

Imperial Leather explained to MailOnline further: 'Besides the brand identity, the sticker on the top is for a long lasting bar and preventing mushiness.

'When the soap is used, the sticker will make and keep the top surface, where the sticker is on, concave.

'After use, the soap is supposed to be upside down. The concave surface will help water run out from the bar and minimise the touching surface on a soap tray.'

Imperial Leather was initially a scent first created in 1798 by Royal London perfumery Bayley’s of Bond Street, which was visited by Russian nobleman Count Olaf, who requested they create a fragrance reminiscent of the distinct aroma of the Russian Courts.

It was named ‘Eau de Cologne Imperiale Russe’, and became his favourite fragrance.
