Waterproof Eyeliner and Mascara Formulation Guidance

While a complete, ready-to-use formula for waterproof and lash-thickening eyeliner and mascara is not available, we can provide guidance on the key types of ingredients typically used in such formulations and their functions.

To achieve waterproof properties and add thickness to lashes, formulations often include:

• Film Formers: These ingredients create a flexible film on the lashes or skin, providing water resistance and hold. Examples include polymers like Resist Film or Polyacrylate-21.
• Fibers: For thickening and lengthening effects in mascara, fibers such as Lash Fiber (Long/Thick) or Lash Fiber (Short/Thin) are incorporated into the formula. These small fibers adhere to the natural lashes, building volume and length.
• Thickeners and Rheology Modifiers: Ingredients like Disteardimonium Hectorite are used to create the desired texture and stability of the product, ensuring it applies smoothly and stays in place.
• Colorants: Black pigments, such as WaterMix™ Black dispersions (Carbon Black or Iron Oxides Black), provide the intense color for both eyeliner and mascara.
• Bases: Formulations are built upon a base, which can be a pre-made option like Mascara Base or a custom blend of waxes, oils, and emulsifiers (for emulsion-based formulas).

Creating a stable and effective waterproof and volumizing product requires careful selection and balancing of these components. The interaction between film formers, thickeners, and pigments is crucial for performance, wear, and ease of application.

While we cannot provide a specific formula, understanding the role of these key ingredient types can help in exploring potential formulation approaches.
