Is PVP a Microplastic?

Polymethyl methacrylate (PMMA)

A part from the microplastics in shampoo, the plastic most commonly found in hair sprays is Polyvinylpyrrolidone (PVP). It is at its most dangerous point when applied to the hair and heated up with styling tools.

Is PVP a silicone?

To understand how this silicone made a better hairspray, it helps to understand how the hairspray works in the first place. When you spray it on, the polyvinylpyrrolidone forms a thin coating on the hair. This coating is stiff and keeps the hair from moving around.

What is the disadvantage of PVP?

The advantages of utilizing PVP are that there are no additional process and no more required energy input. However, one of the disadvantages of PVP in the experiment is its dissolution process, which requires a certain amount of time.

Is PVP a natural ingredient?
