What is Oxidized Polypropylene?
Oxidized Polypropylene is a cosmetic ingredient primarily used for its ability to form protective layers. This substance creates a thin coating on the skin or hair, which helps retain moisture and shield against outside factors. The protective layer forms through a process of film formation, where the oxidized polypropylene molecules spread evenly across the surface and bond together. This continuous film acts as a barrier, trapping moisture within the skin or hair shaft and preventing its escape into the environment. Simultaneously, it creates a physical shield that blocks external elements such as pollutants and irritants from coming into contact with the skin or hair surface.
The production process involves modifying a common plastic by introducing oxygen to change its chemical structure. This transformation alters the material’s properties, making it more flexible and better at sticking to surfaces. The oxidation process involves exposing polypropylene to oxygen at high temperatures, which breaks some of the polymer chains and introduces oxygen-containing groups. These new functional groups enhance the material’s polarity, improving its adhesion to skin and hair. The increased flexibility allows the oxidized polypropylene to conform to the contours of the application area, ensuring even coverage and a smooth feel.
These improved characteristics make it well-suited for use in various cosmetic products. In skincare formulations, the protective layer formed by oxidized polypropylene helps maintain skin hydration by reducing transepidermal water loss. This results in softer, more supple skin with improved texture. In hair care products, the film-forming properties create a protective coating around each hair strand, enhancing shine and reducing frizz by smoothing the hair cuticle.
Who Can Use Oxidized Polypropylene?
This ingredient is generally suitable for all skin types as it forms a non-occlusive film, meaning it does not clog pores or suffocate the skin. However, if you have extremely sensitive skin or conditions like eczema or rosacea, you might want to patch test first or consult with a dermatologist, as the film-forming nature might irritate sensitive conditions.
For vegans and vegetarians, Oxidized Polypropylene is a suitable choice. It is synthesized from polypropylene, which is a petroleum-derived product, not derived from animal sources. This makes it compatible with vegan and vegetarian lifestyles.
Regarding its use during pregnancy or breastfeeding, there are no specific contraindications. However, as with any cosmetic ingredient, it is always prudent for pregnant or breastfeeding women to consult healthcare providers about the products they use, to ensure safety for both mother and baby.
Potential Side Effects/Adverse Reactions
Side effects and reactions to the topical application of Oxidized Polypropylene can vary from person to person. Here are some potential side effects:
- Redness or irritation at the application site
- Itching or swelling
- Dermatitis or allergic skin reactions
- Dryness or peeling of the skin
If you experience any of these side effects while using a product containing Oxidized Polypropylene, it is advisable to discontinue use immediately and consult a healthcare professional.
While the list of potential side effects might sound extreme or scary, it’s important to note that adverse reactions to Oxidized Polypropylene are relatively rare. Most people use products containing this ingredient without any negative effects.
Given the variability in how different people’s skin can react to new substances, the importance of patch testing cannot be overstated. Applying a small amount of the product to a discreet area of skin and waiting 24 hours to observe any reactions is a crucial step in ensuring your skin’s compatibility with new cosmetic products.
Comedogenic Rating
Comedogenicity refers to the potential of cosmetic ingredients to cause comedones, which are skin blemishes commonly known as blackheads or whiteheads. This is particularly relevant for individuals with acne-prone skin, as some ingredients can exacerbate or trigger breakouts by clogging pores.
Oxidized Polypropylene has a comedogenic rating of 0. This rating indicates that it is non-comedogenic and does not pose a risk of clogging pores or exacerbating acne. The molecular structure and properties of Oxidized Polypropylene allow it to sit on the skin without penetrating the follicles, thereby minimizing the risk of comedones formation.
Given its non-comedogenic rating, Oxidized Polypropylene is generally suitable for individuals who are prone to acne or breakouts.
Conclusion
Oxidized Polypropylene primarily functions as a film-forming agent in cosmetics. This property allows it to create a continuous film on the surface of the skin or hair, providing a protective barrier and enhancing the texture of the product.
Despite its functional benefits, Oxidized Polypropylene is not particularly popular in the cosmetic industry compared to similar ingredients that offer additional benefits such as moisturization or anti-aging properties. Its use case within contemporary cosmetic formulations remains limited, primarily due to the availability of more versatile ingredients.
Regarding safety, Oxidized Polypropylene is considered safe for use in cosmetic products. Its stability and lack of skin penetration minimize potential for irritation or adverse effects, making it a reliable choice for formulating gentle and non-irritating cosmetic products.
