Almost two out of every three people think microbeads, used in things like face washes and shower gels, should be banned in the UK according to a poll.
That figure comes from Greenpeace who spoke to 1,000 people, many of whom did not know what microbeads were before they were asked.
These tiny plastic beads are included in toiletries to exfoliate the skin.
Water treatment systems cannot filter them so they eventually flow into the oceans where they damage marine life.
The US has already put in place a ban on microbeads. Canada, as well as some EU countries, are looking to introduce similar laws. The UK is yet to follow suit.
"Microbeads are one of those rare environmental problems that are actually relatively easy to solve," said Louise Edge, oceans campaigner at Greenpeace UK.
"A ban is easy to introduce and alternatives are already available.
"Although it would not alone eradicate the problems caused by microplastics, it would set an important precedent in the UK that pumping plastics into our oceans is not acceptable."
Greenpeace says, external: "Up to 100,000 microbeads can be washed down the sink with the single application of some products."
Only one in ten of those asked thought microbeads should definitely not be banned in the UK.
Almost seven out of ten did not know what a microbead was before they participated in the poll, carried out by Censuswide. Young women were the most likely to be aware of them.
"There still needs to be a lot more scientific research to show how damaging it [microplastic] has been for marine life," Emma Cunningham of the Marine Conservation Society told Newsbeat, earlier this year.
"The evidence is there to suggest animals right at the bottom of the food chain are ingesting it and we worry what impact that will have higher up the food chain."
If you're looking for something to exfoliate, she suggests using natural alternatives including oats, sea salt and ground nut shells.
The UK Parliament is currently looking into the effects of microplastics on the environment. Part of their research will investigate whether eating fish which have consumed microplastics has an effect on people.
A spokesperson for Defra said they are "backing action at a European level" to end the use of microplastics.
"Already many firms have taken action to remove microbeads from their products, but everyone can play their part in keeping our seas safe by making informed shopping decisions," they added.
Unilever announced in 2012 that it would be phasing out microbeads by 2015 and other companies have started to follow suit.
Companies including Asda, Avon, the Bodyshop, L'Oreal and Boots are pledging not to use them on their own-brand products - but may still stock other items with microbeads in, say Greenpeace.
Some other unusual findings came out of the poll.
More than 4% of people who filled out the survey were under the impression microbeads were sex toys. Almost one in ten people from Edinburgh also thought that.
Out of the 1,000 people asked, a small number - 16 - said they had never purchased toothpaste. Three-quarters of those were men.
The poll also showed that about one in 10 men say finding out a company does animal testing would not affect the chances of them buying their products in the future.
