What it is
Polyvinyl Acetate Emulsion is an adhesive polymer that’s milky white in colour and is often used as an emulsion in water. More simply put, it is PVA glue.
What it does
Polyvinyl Acetate Emulsion is mostly used in peel-off nail polishes and face masks for its ability to create an adhesive film that is easy to remove. That’s because, once the water evaporates, the adhesive that’s left behind doesn’t have a very strong hold when applied on a smooth surface like that of the nail and can so be peeled off in big chunks. On porous materials such as wood, its hold is much more resistant.
Polyvinyl Acetate Emulsion is generally considered to be safe. However, if it chips, it may remove a big chunk of the nail polish too, completely ruining your manicure.
