Polypropylene

What Polypropylene is & what it does

Polypropylene is a synthetic thermoplastic polymer made from propylene monomers. In cosmetics and sunscreens it is used in solid form as an opacifying agent, a bulking filler, or as fine particles that add texture and slip to a formula. It is a chemically stable, water-insoluble material that does not contribute active skincare benefits.

Is Polypropylene safe in skincare?

Polypropylene is widely used in cosmetics and is generally regarded as a stable, inert material on the skin. It is a solid synthetic polymer that sits on the surface rather than penetrating, which is why it is commonly used as a filler or texturizing particle. As with any product, suitability can vary by individual, so patch testing a new formula is sensible.

Is Polypropylene comedogenic or does it clog pores?

Polypropylene is an inert plastic polymer and is not typically flagged as a notably pore-clogging ingredient. Because it is used in small amounts as a particle or filler, its effect on pores is generally considered low. If you are acne-prone, you may still want to monitor how a specific formula suits your skin.

Is Polypropylene natural or synthetic?

Polypropylene is fully synthetic. It is a man-made thermoplastic polymer produced from propylene, a petrochemical-derived monomer. It does not occur naturally in plants or minerals.
