  • Novel Form of Plastic Bottle allows All of the Shampoo to Come Out in the End

A novel form of plastic bottle allows all of the shampoo contained in it to come out in the end leaving not even a single droplet behind.

It is a commonplace occurrence. You are left with the last dollop of shampoo in the bottle. So you put some water in the bottle, shake it and leave it upside down for awhile. Yet still some of the shampoo remains stuck to the inner surface of the bottle. This is when you feel so frustrated that you want to scream out in agony. Yet now scientists have found a solution to this problem too. 

Engineers from Ohio State University have developed a special inner coating for plastic bottles that allows you to get the complete shampoo out from it at the drop of a hat. It almost works in a magical manner.

The new invention is still in its patent-pending stage though. This method is less complex, does not cost much and is not a hazard for the environment. Other methods that had been tried up until now had failed. This one though has hit the nail on the head. 

Soaps tend to have less of a surface tension. This allows them to bond with oil and water. It is this process that makes anyone squeaky clean after entering and emerging from a shower. Yet this same quality makes the soap or shampoo stick to the inner surface of the bottle in which it is contained.

A coating made from a solvent and very fine silica particles was sprayed on the inside of the bottles at the time of their manufacturing. As soon as the plastic solidified, the silica formed a layer on the inner surface. 

Air pockets were created and these allowed the soap or shampoo to slide off easily into the hands of the person in the shower. This principle has been used before in case of mayo and ketchup.

Yet soap remained the acid test and it was an unresolvable problem. Soap has a different nature from various foods. So a different layer of material was needed for soap to slide off. It is hoped that this new methodology will allow soap to be saved in the future.

Also recycling will be easier since there will not be any soap or shampoo to clean out arduously from the bottles before sending them for processing and renewal. 

The research on this new technology described in a paper that appeared in the journal Philosophical Transactions of the Royal Society.
