POLYPROPYLENE TEREPHTHALATE

Description

Polypropylene terephthalate (PPT) is a synthetic polymer gaining attention in the skincare and cosmetics industry for its unique properties and versatile applications. This thermoplastic polyester is derived from terephthalic acid and propylene glycol, resulting in a material that combines strength, flexibility, and chemical resistance.

In skincare formulations, PPT serves multiple functions. It acts as a film-forming agent, creating a protective barrier on the skin's surface that helps retain moisture and shield against environmental stressors. This property makes it particularly useful in long-wearing makeup products and sunscreens. PPT also functions as a texture enhancer, improving the spreadability and feel of creams and lotions.

The polymer's resistance to oils and solvents makes it an excellent choice for oil-control products and mattifying formulations. Its stability under various pH conditions ensures compatibility with a wide range of active ingredients. PPT's low water absorption rate contributes to the water-resistance of products, making it valuable in sweat-proof and waterproof cosmetics.

While PPT offers numerous benefits, formulators must consider its potential environmental impact, as it is not biodegradable. Ongoing research focuses on developing more sustainable alternatives or improving its recyclability in cosmetic packaging.
