The Nyx Jumbo Lash! 2-in-1 Liner & Adhesive product is composed of a combination of chemicals that serve dual functions in the context of eyelash application. The adhesive component of the product is primarily based on acrylates copolymer, which forms a strong bond with the keratin proteins present in eyelashes. Acrylates copolymer is known for its adhesive properties due to its ability to crosslink and adhere to various surfaces, providing long-lasting hold. In addition to the adhesive component, the 2-in-1 product also contains ingredients that function as a liner. The liner component is typically composed of various waxes, such as beeswax or carnauba wax, which help to create a smooth and defined line along the lash line. These waxes provide a barrier that prevents the adhesive from smearing or spreading beyond the desired application area. The pH of the Nyx Jumbo Lash! 2-in-1 Liner & Adhesive product is formulated to be around neutral (pH 7), which is compatible with the pH of the skin around the eye area. This helps to minimize irritation or allergic reactions that may occur with products that have a significantly different pH. The viscosity of the product is carefully controlled to ensure ease of application with the included brush applicator. The precise viscosity also aids in preventing the liner or adhesive from running or smudging during wear.
