Micellar Water Formulation Guidance

Hello! Thank you for sharing your Micellar Water formula. It looks like a good base for a DIY product.

You have two main questions: finding a substitute for Disodium Cocoamphodiacetate and the correct mixing order for the ingredients.

Substitute for Disodium Cocoamphodiacetate

Disodium Cocoamphodiacetate is a mild amphoteric surfactant that helps cleanse and create a gentle foam in your formula. If you're looking for alternatives, consider other mild surfactants suitable for facial cleansing products.

Based on the available ingredients, two potential substitutes or complementary surfactants you could explore are:

• Sodium Cocoyl Glycinate: This is an amino acid-derived surfactant known for being moisturizing and creating a good lather. It's suitable for cleansing products.
• Sucrose Cocoate: This is a natural, sugar-based surfactant blend. It's known for increasing foam density and stability, providing a moisturizing effect, and improving skin feel. It's also readily biodegradable and suitable for gentle cleansers.

Both of these could potentially replace or be used in combination with other surfactants in your formula, depending on the desired cleansing strength and feel. Always test small batches when substituting ingredients.

Mixing Order

For a simple water-based formula like this Micellar Water, the exact mixing order isn't as critical as ensuring each ingredient is fully dissolved or dispersed before adding the next. However, a recommended order helps ensure proper incorporation and stability:

1. Start with the Water (RO).
2. Add Disodium EDTA to the water and stir until completely dissolved. EDTA helps chelate metal ions in the water, improving formula stability.
3. Add Hexylene Glycol and Glycerin. Mix well until fully combined with the water phase.
4. Gently add Poloxamer 184 and your chosen surfactant (either Disodium Cocoamphodiacetate or the substitute like Sodium Cocoyl Glycinate or Sucrose Cocoate). Mix slowly and gently to avoid creating excessive foam.
5. Finally, add Polyaminopropyl Biguanide (the preservative). Mix until the entire solution is uniform and clear.

Ensure each ingredient is fully incorporated before adding the next. The final product should be a clear liquid.

Hope this helps with your formulation!
