Peg 9, also known as Polyethylene Glycol 9, is a water-soluble polymer that is commonly used in cosmetics as an emulsifier, surfactant, and moisturizer. It is a type of polyethylene glycol that has a molecular weight of around 400.

2. Use:

Peg 9 is used in cosmetics to help blend oil and water-based ingredients together, stabilize formulations, and improve the texture and spreadability of products. It is commonly found in creams, lotions, shampoos, and other skincare products.

3. Usage Peg 9:

Peg 9 is generally considered safe for use in cosmetics when used in concentrations that comply with regulatory guidelines. However, some individuals may be sensitive to Peg compounds and may experience irritation or allergic reactions when using products containing Peg 9. It is important to perform a patch test before using a product with Peg 9, especially if you have sensitive skin.

Precautions: While Peg 9 is considered safe for use in cosmetics, some studies have raised concerns about potential contamination with harmful impurities such as 1,4-dioxane. To minimize the risk of exposure to these impurities, it is recommended to choose products from reputable brands that follow strict quality control measures. Additionally, individuals with sensitive skin or a history of allergic reactions should consult with a dermatologist before using products containing Peg 9.
