Polypropylene, also known as 1-Propene, homopolymer, is a synthetic polymer derived from the polymerization of propene (or propylene) monomers. In the context of cosmetics, it is primarily used as a viscosity controlling agent. This means it helps to adjust the thickness or flow of cosmetic products, ensuring they have the right consistency for application.
Polypropylene has a rich history that dates back to the mid-20th century. It was first polymerized in 1954 by the Italian chemist Giulio Natta and his German counterpart Karl Rehn. Since then, its versatile properties have made it a popular choice in various industries, including cosmetics. Its introduction into the cosmetic world was driven by its stability, non-reactivity, and ability to blend well with other ingredients.
The production of polypropylene involves a process called polymerization, where propene monomers are chemically bonded to form long chains. This is typically achieved through the use of catalysts under controlled conditions of temperature and pressure. The resulting polymer is then processed into various forms, such as powders or granules, which can be easily incorporated into cosmetic formulations.
In this section, we will delve into the officially recognized cosmetic benefits and uses of Polypropylene:
Polypropylene is primarily used in cosmetics for its viscosity-controlling properties. But what does that mean for you? Essentially, viscosity refers to the thickness or thinness of a liquid. By controlling viscosity, Polypropylene helps to ensure that your favorite lotions, creams, and other beauty products have the right consistency. This means they are neither too runny nor too thick, making them easier to apply and more effective in delivering their active ingredients to your skin.
Note: the listed benefits above are exclusively based on the officially recognized and defined functions of the ingredient, as documented by the International Nomenclature of Cosmetic Ingredients (INCI).
Polypropylene is generally considered safe for use in cosmetics and personal care products. It is a synthetic polymer that serves primarily as a viscosity controlling agent, helping to maintain the desired consistency of a product. However, like any ingredient, it may have potential side effects and considerations that users should be aware of.
Regarding individuals who are pregnant or breastfeeding, data and research on the topical usage of polypropylene during pregnancy and breastfeeding are lacking. Therefore, it is advisable for these individuals to consult a healthcare professional for further advice before using products containing this ingredient.
Adverse reactions to polypropylene are uncommon, but it is always a good practice to conduct a patch test before widespread usage to ensure that you do not have a sensitivity to the ingredient.
Polypropylene has a comedogenic rating of 0, meaning it is considered non-comedogenic. This makes it suitable for individuals who are prone to acne, blemishes, or breakouts, as it is unlikely to clog pores or exacerbate these conditions.
