Eyebrow Paint Formulation Considerations

Your list of ingredients provides a good starting point, including a solvent (Isopropyl Alcohol), humectant (Glycerin), potential skin conditioners (Madecassic Acid, Vitamin E), and a pigment (CI77499 / SI-2 BLACK BL-100). However, this list is not a complete, ready-to-use formula, and specific proportions are crucial for performance, stability, and safety.

Here's a look at the ingredients you mentioned and their roles:

• AQUR: This term is unclear, but if it refers to an aqueous component like water, it would serve as a primary solvent in the formulation.
• Isopropyl Alcohol: A solvent that helps dissolve ingredients and can contribute to a faster drying time.
• Glycerin: As confirmed by the product description for Glycerin (USP/Food Grade), this acts as a humectant, helping to retain moisture and improve the texture and feel of the product on the skin. It is typically used at 1-100% in cosmetics, but not applied directly to the skin at high concentrations.
• MADECASSIC ACID: The product description for Madecassic acid (85%, Powder) indicates it is derived from Centella Asiatica and has potential anti-inflammatory, antioxidant, and collagen-boosting properties. It's typically used at a low rate (0.01-0.1%) and should be added in the final step without heat above 40°C.
• Tocopheryl Acetate: The product description for Vitamin E (Tocopheryl Acetate) confirms it is a stable form of Vitamin E used as an antioxidant and skin conditioning agent. It is oil-soluble and typically used at 0.1-1%.
• CI77499: This is a common cosmetic pigment, likely corresponding to SI-2 BLACK BL-100, which is Iron Oxide Black used for coloring. Proper dispersion is needed for even color.
• POLYESTER FILM: Adding a film-forming polymer is an excellent approach to enhance water resistance and wear properties. The search results included Allianz OPT (Acrylates/C12-22 Alkyl Methacrylate Copolymer), which is described as a polymer film former that provides water and wear resistance. It is dispersible in water and has a suggested utilization rate of 1-5%.

Missing Components:

Your list is missing several key components typically required for a stable and functional eyebrow paint, such as:

• Thickeners or Rheology Modifiers: To achieve the desired texture, viscosity, and prevent pigment settling.
• Emulsifiers (if needed): If the formula contains both oil and water phases that need to be blended.
• Preservatives: Essential to prevent microbial growth, especially in water-containing formulas.
• Pigment Dispersants: To ensure the CI77499 pigment is evenly distributed and doesn't clump.

Regarding Proportions and Adding POLYESTER FILM:

It is not possible to provide exact percentages for each ingredient without developing and testing a specific formulation. The optimal percentage for each component, including a film former like Allianz OPT, depends on the desired properties of the final product (e.g., consistency, drying time, intensity of color, level of water resistance, skin feel).

Adding a film former like Allianz OPT at the recommended usage rate (1-5%) is a suitable way to increase water resistance. However, integrating it correctly into the formula requires careful consideration of its compatibility with other ingredients and its impact on the overall rheology and stability.

Conclusion:

While your ingredient list contains relevant components for an eyebrow paint, it is not a complete formula. Developing a stable and effective cosmetic product requires expertise in formulation chemistry to determine the correct ingredients, their precise proportions, and the manufacturing process. Adding a film former like Allianz OPT is a valid approach for water resistance, but the exact percentage should be determined through formulation trials.

It is highly recommended to consult with a cosmetic chemist or refer to established cosmetic formulation guidelines and sample formulas to create a safe and effective product.
