POLYETHYLENE ISOTEREPHTHALATE

Description

Polyethylene Isoterephthalate (PIT) is a synthetic polymer widely used in cosmetic and skincare formulations. This versatile ingredient functions primarily as a film-forming agent and texture enhancer. PIT forms a thin, flexible layer on the skin's surface, providing a smooth, even application of products like foundations, sunscreens, and moisturizers.

PIT's molecular structure allows it to create a breathable barrier that helps retain moisture while still allowing the skin to perspire naturally. This property makes it particularly useful in long-wearing makeup formulations and water-resistant sunscreens. The ingredient also contributes to the stability of emulsions and suspensions, improving the overall texture and shelf life of skincare products.

In terms of safety, PIT is generally considered non-irritating and suitable for most skin types. It has a low risk of allergic reactions and is not known to clog pores. However, as with any synthetic ingredient, some individuals may experience sensitivity. PIT is often used in concentrations ranging from 0.1% to 5% in skincare formulations, depending on the desired effect and product type. Its ability to enhance product performance without compromising skin health makes it a valuable component in modern skincare technology.
