False Claim – Colour of Squares on Tubes Denotes Chemical Content

Outline

Circulating message claims that consumers can tell the chemical makeup of tube contents just by checking the colour of a small square at the bottom of the packaging. A newer variant focuses on toothpaste tubes. 

Brief Analysis

The claims in the message are false. The squares, called “eye marks”, are marks used in the packaging process and do not indicate the chemical content of the tubes in any way whatsoever. The marks tell packaging machines when to perform certain tasks such as cutting or crimping tubes.

Example

Pay attention when buying toothpaste,
at the bottom of the toothpaste tube
there is a color bar. And do you only know
the original meaning of the color bar!
Try to choose green and blue, there are four kinds:Green: natural;
Blue : Natural + Medicine;
Red : Natural + Chemical composition;
Black : pure chemical.

Toothpaste Squares on Tubes

 

Did you know squares on tubes means something …. Green : All naturals Red : some natural ,but most chemicals Black : Only chemicals

Squares on Tubes

 

Detailed Analysis

This piece of “advice”, which is currently making its way around via social media and the blogosphere, claims that all one need do to find out the chemical makeup of tube contents such as toothpaste and creams is to check the colour of a small square on the bottom of the tube. According to the message, a green square means contents are all natural, red means mostly chemicals with some natural composition and black means only chemicals are used.

But alas, this supposed helpful tip is, in fact, utter nonsense.

The rectangular marks or lines on tubes referred to in the message are using in the packaging process. The marks are known in the packaging industry as “eye marks” (or sometimes “eye spots”). They do not in any way indicate the chemical content of the tubes they are displayed on, regardless of what colour they are. That is not their role. 
Eye marks can be identified by electronic eyes used in sophisticated modern packaging machinery. The marks serve a variety of packaging purposes such as telling the machine where to cut and crimp tubes or indicating the desired colour of print on packaging. Many products have such eye marks, although they may not always be visible to consumers as they are on tubes.

Rather ironically, the message poses the question “did you know squares on tubes mean something” and then answers the question with an outright lie. In fact, the “squares” do mean something – to packaging machines and the people who operate them. But, to the average consumer, they mean nothing at all.

Want to know what a tube’s contents consist of? It is most likely listed right there on the side of the tube in some detail. Or, you might find even more detailed information about the product’s content on the company’s website or elsewhere on the Internet. But rest assured, the colour of the little mark on the tube’s base will tell you nothing whatsoever about its chemical makeup.



Importance Notice

After considerable thought and with an ache in my heart, I have decided that the time has come to close down the Hoax-Slayer website.

These days, the site does not generate enough revenue to cover expenses, and I do not have the financial resources to sustain it going forward.

Moreover, I now work long hours in a full-time and physically taxing job, so maintaining and managing the website and publishing new material has become difficult for me.

And finally, after 18 years of writing about scams and hoaxes, I feel that it is time for me to take my fingers off the keyboard and focus on other projects and pastimes.

When I first started Hoax-Slayer, I never dreamed that I would still be working on the project all these years later or that it would become such an important part of my life. It's been a fantastic and engaging experience and one that I will always treasure.

I hope that my work over the years has helped to make the Internet a little safer and thwarted the activities of at least a few scammers and malicious pranksters.

A Big Thank You

I would also like to thank all of those wonderful people who have supported the project by sharing information from the site, contributing examples of scams and hoaxes, offering suggestions, donating funds, or helping behind the scenes.

I would especially like to thank David White for his tireless contribution to the Hoax-Slayer Facebook Page over many years. David's support has been invaluable, and I can not thank him enough.

Closing Date

Hoax-Slayer will still be around for a few weeks while I wind things down. The site will go offline on May 31, 2021. While I will not be publishing any new posts, you can still access existing material on the site until the date of closure.

Thank you, one and all!
