Formula Review for Micellar Cleansing Water

Let's review the proposed formula for your Micellar Cleansing Water based on the ingredients provided:

Compatibility and Suitability of Ingredients

Based on the known properties of the ingredients:

• Compatible and Suitable:

  • PEG-6 Caprylic/Capric Glycerides (MakeUp-Wash™) 5%
  • PEG-7 Glyceryl Cocoate (Coco Wash™) 3%
  • Natural Moisturizing Amino Acids
  • HyaCoat™ (Cationic Hyaluronic Acid)
  • Disodium EDTA

• Preservatives: Your formula includes two preservatives: Phenoxyethanol SA and Eye Preserved™. It is generally recommended to choose only one broad-spectrum preservative system for a formula. You should select either Phenoxyethanol SA or Eye Preserved™, but not both, to avoid potential compatibility issues or over-preservation.

• Incompatible: Lecithin is not soluble in this type of water-based micellar formula and should be removed.

• Ingredients requiring more information: Compatibility and suitability for SEBARYL and ginkgo (biloba) extract cannot be fully assessed without more specific information about these particular ingredients.

Efficacy

• The combination of MakeUp-Wash™ and Coco Wash™ provides a good base for a micellar cleansing water. MakeUp-Wash™ is known for its makeup removal efficacy, while Coco Wash™ adds gentleness and a conditioning feel.
• Including Natural Moisturizing Amino Acids and HyaCoat™ is beneficial for adding moisturizing properties, which helps to counteract any potential dryness from cleansing, even in a rinse-off product. HyaCoat™, being cationic, is designed to adhere better to the skin even after rinsing, providing longer-lasting hydration.
• Disodium EDTA acts as a chelating agent, helping to improve formula stability and efficacy by binding to metal ions in the water.

Cost-Effectiveness

Using multiple specialized ingredients like MakeUp-Wash™, Coco Wash™, Natural Moisturizing Amino Acids, and HyaCoat™ will generally result in a higher cost compared to simpler micellar water formulations. The cost-effectiveness depends on the desired performance and target market for the product.

Adding Vitamin E

Regarding your previous question about adding Vitamin E (Tocopheryl Acetate), while Vitamin E is a beneficial antioxidant and skin conditioner, its effectiveness in a rinse-off product like micellar water is limited as it is washed away shortly after application. The oil-soluble form of Vitamin E (Tocopheryl Acetate) may also be difficult to fully incorporate into a clear, water-based micellar system without affecting clarity or stability. For antioxidant benefits, it is generally more effective in leave-on products.

In summary, the core of your formula with MakeUp-Wash™, Coco Wash™, Natural Moisturizing Amino Acids, HyaCoat™, and Disodium EDTA is sound. Remember to remove Lecithin and choose only one preservative system (either Phenoxyethanol SA or Eye Preserved™).
