- One of its most popular uses in skin care products is as an ingredient in exfoliators, in which small beads made of Polyethylene are used for smoothing or polishing the skin.
- Polyethylene is often seen in formulas because of its ability to bond other ingredients together, such as in make up foundations and compressed powder cakes. It can also be used to dilute solids, increase the thickness of formulas, or help keep emulsions from separating into oil and water components. It dries to form a thin coating on the skin, hair or nails, and is also seen as a toothpaste ingredient because of its ability to polish the teeth thanks to its exfoliating properties.
