Plastic items (including period care products) that end up in the ocean will continue to break into smaller and smaller microplastics, adding to the plastic smog of 170 trillion pieces already ...
Polyvinyl chloride (alternatively: poly (vinyl chloride), [ 6][ 7] colloquial: vinyl[ 8] or polyvinyl; abbreviated: PVC[ 8]) is the world's third-most widely produced synthetic polymer of plastic (after polyethylene and polypropylene ). About 40 million tons of PVC are produced each year.
These products are typically composed of polyethylene, a common component of plastics, but they can also be manufactured from polypropylene, polyethylene terephthalate (PET), and nylon. [83] They are often found in face washes, hand soaps, and other personal care products; the beads are usually washed into the sewage system
Signed into law by President Barack Obama on 2015-12-28. The Microbead-Free Waters Act of 2015 is a United States law that prohibits the addition of plastic microbeads in the manufacturing of certain personal care products, such as toothpaste. The purpose of the law is to reduce water pollution caused by these products.
A microbead imaged using scanning electron microscopy. Microbeads are manufactured solid plastic particles of less than one millimeter in their largest dimension [4] when they are first created, and are typically created using material such as polyethylene (PE), polyethylene terephthalate (PET), nylon (PA), polypropylene (PP), and polymethyl methacrylate (PMMA).

The environmental effect of pharmaceuticals and personal care products ( PPCPs) is being investigated since at least the 1990s. PPCPs include substances used by individuals for personal health or cosmetic reasons and the products used by agribusiness to boost growth or health of livestock. More than twenty million tons of PPCPs are produced ...
Plastisol. Plastisol. A plastisol is a colloidal dispension of small polymer particles, usually polyvinyl chloride (PVC), in a liquid plasticizer. When heated to around 180 °C (356 °F), the plastic particles absorb the plasticizer, causing them to swell and fuse together forming a viscous gel. Once this is cooled to below 60 °C (140 °F) it ...
Polyvinylidene chloride is applied as a water-based coating to films made of other plastics, such as biaxially-oriented polypropylene (BOPP) and polyethylene terephthalate (PET). This coating increases the barrier properties of the film, reducing the permeability of the film to oxygen and flavours and thus extending the shelf life of the food ...
