Question

Please help check the compatibility of the ingredients in this serum formulation and provide the recommended mixing procedure. The goal is to create an anti-aging, brightening, and plumping serum suitable for morning and evening use. It should be non-comedogenic, with a thick yet light, soft, and smooth texture that absorbs quickly.

Formulation Details:

  1. Rose Water (Rosa Damascena) 50%
  2. Disodium EDTA 0.2%
  3. Allantoin 0.3%
  4. Safe-B3™ (Vitamin B3, Niacinamide) 5%
  5. GlucoBright™ (Acetyl Glucosamine) 4%
  6. DMAE (SkinTight MD™) Liquid 3%
  7. Panthenol (Vitamin B5, DL-Panthenol, Powder) 2%
  8. Wrinkle-Fill™ (Acetyl-Tyrosine) 2%
  9. Wrinkle-Lax™ 0.5%
  10. Sodium Copper Chlorophyllin Complex 0.5%
  11. Centella Asiatica Extract (Madecassoside 90%) 0.5%

  19. RO Water (q.s. to 100%)

Specific Questions:

  1. Is this ingredient list comprehensive? Are there any unnecessary ingredients that should be removed?
  2. Are all ingredients compatible in a single formula, or should any be separated into a different product?
  3. Can I use Rose Water to dissolve the powdered ingredients directly?
  4. Is 2% Mild Preserved Eco™ sufficient for this formula, or do I need additional preservatives?
  5. Regarding Centella Asiatica Extract (Madecassoside 90%), should I sprinkle the powder in the final step or dissolve it in water first?
  6. Please provide the full mixing instructions and steps.

Answer

The serum formula you have designed is very comprehensive, covering anti-aging, brightening, and hydration. Here is the compatibility check and recommendations:

1. Formula Coverage and Ingredients

  • Coverage: The formula is excellent. The combination of Safe-B3™ (5%) and GlucoBright™ (4%) is a proven synergistic duo for brightening. DMAE, Wrinkle-Fill™, and Wrinkle-Lax™ provide strong anti-aging and firming benefits.
  • Recommendation: Sodium Copper Chlorophyllin Complex at 0.5% will result in a very intense dark green color. If you prefer a light green "serum" look, I recommend reducing this to 0.01% - 0.05%.

2. Compatibility and Stability

  • The pH Challenge: DMAE Liquid is highly alkaline (high pH). However, Safe-B3™, GlucoBright™, and Madecassoside require a pH range of approximately 5.5 - 6.0 to remain stable and effective.
  • Electrolyte Sensitivity: Your formula contains many electrolytes (Niacinamide, GlucoBright, DMAE, and Magnesium Sulfate). Silky Serum Base is a ready-to-use base, but at only 10%, it may become very thin (runny) when mixed with these high-electrolyte actives. To achieve a "thick but light" texture, you may need to increase the base percentage or add a thickener.
  • Separation: There is no immediate need to separate the formula into two products, provided you manage the pH correctly.

3. Dissolving Powders in Rose Water

  • Yes, you can use Rose Water to dissolve water-soluble powders (Allantoin, Niacinamide, Panthenol, etc.) directly. However, ensure the total water volume is sufficient to dissolve everything.

4. Preservative Sufficiency

  • Mild Preserved Eco™ at 2% is generally sufficient. However, since your formula contains a high amount of natural extracts and Rose Water, ensure the final pH is below 6.0 for optimal preservative efficacy.

5. Mixing Madecassoside 90%

  • Madecassoside should be dissolved in the water phase before mixing with the base. You do not need to "sprinkle" it at the end. Dissolve it in a small portion of RO water or Rose Water first to ensure it is completely clear before adding it to the main mixture.

Recommended Mixing Steps

  1. Water Phase: Mix RO Water, Rose Water, Disodium EDTA, Allantoin, Safe-B3™, GlucoBright™, Panthenol, Sialic Acid, and Magnesium Sulfate. Stir until completely dissolved. (Slight warming can help Allantoin dissolve faster).
  2. Active Phase: Add Yeast Radiance™, MOIST24, Rose Extract, Wrinkle-Fill™, Wrinkle-Lax™, Sodium Copper Chlorophyllin, and the pre-dissolved Madecassoside.
  3. pH Adjustment (Crucial): Add DMAE Liquid. Use a pH meter or strips. The pH will likely rise. Use a Citric Acid solution (gradually drop by drop) to adjust the pH back down to 5.5 - 6.0.
  4. Base Incorporation: Gradually add the water mixture into the Silky Serum Base while stirring continuously until a uniform serum texture is formed.
  5. Preservation: Add Mild Preserved Eco™ and stir well.

Note: If the serum is too thin after step 4, you may need to add more Silky Serum Base or a small amount of a gelling agent.

Follow-up Questions:

  1. When increasing the percentage of the Silky Serum Base, should I decrease the water percentage accordingly? For example, if I increase the base from 10% to 15%, should I reduce the water by 5%, or can I simply add more base if the texture is not thick enough?
  2. If I want to add a gelling agent, which one should I use to achieve a soft, smooth, and non-greasy texture? What is the recommended usage percentage?
  3. What type of packaging is best for this finished serum to maintain the stability and efficacy of the ingredients?
  4. Could you please provide the revised mixing procedure if a gelling agent is added to the formula?

Thank you.

Answer:

Regarding your follow-up questions for the anti-aging and brightening serum:

1. Adjusting the Base Percentage

  • Water Adjustment: Yes, if you increase the Silky Serum Base (Face/Eye) from 10% to 15%, you must reduce the amount of RO Water by 5% to keep the total formula at 100%.
  • Adding Later: While you can add more base later if the texture is too thin, it is better to calculate it beforehand. Interestingly, for this specific base, a higher proportion of water often results in a thicker texture, while more base can make it more liquid. However, with your high electrolyte content (Niacinamide, DMAE, etc.), the electrolytes will likely thin the formula regardless of the ratio.

2. Recommended Gel Maker for Texture

To achieve a thick, smooth, and non-sticky feel while maintaining stability against high electrolytes, I recommend:

  • Pudding Gel Maker™ (Acid/Electrolyte Resistant): This is the best choice for your formula because it is specifically designed to handle high electrolyte loads and acidic environments. It provides a "pudding-like" bouncy texture that is very smooth.
  • Pro Polymer™: Another excellent option that provides a premium, silky skin feel and is highly resistant to electrolytes.
  • Usage Rate: Use 0.5% - 1.0%. This will ensure the serum remains thick and stable even with the DMAE and Vitamin B3.

3. Recommended Packaging

  • Airless Pump Bottle: This is the best choice. It protects the ingredients (especially the extracts and antioxidants) from oxidation by minimizing contact with air and prevents contamination from fingers.
  • Dark Glass Bottle (Amber/Cobalt): If using a dropper, choose dark glass to protect the Sodium Copper Chlorophyllin and extracts from light degradation.

4. Revised Mixing Procedure (with Gel Maker)

  1. Water Phase: Mix RO Water, Rose Water, Disodium EDTA, Allantoin, Safe-B3™, GlucoBright™, Panthenol, Sialic Acid, and Magnesium Sulfate. Stir until dissolved.
  2. Gelling Step: Sprinkle the Pudding Gel Maker™ or Pro Polymer™ into the water phase. Use a high-speed stirrer or blender until a smooth gel is formed.
  3. Active Phase: Add Yeast Radiance™, MOIST24, Rose Extract, Wrinkle-Fill™, Wrinkle-Lax™, Sodium Copper Chlorophyllin, and the pre-dissolved Madecassoside.
  4. pH Adjustment: Add DMAE Liquid. The pH will rise significantly. Gradually add a Citric Acid solution (dissolved in a tiny bit of water) drop by drop while testing the pH until it reaches 5.5 - 6.0.
  5. Emulsification: Gradually add the water-gel mixture into the Silky Serum Base (Face/Eye). Stir or blend until the texture is uniform and smooth.
  6. Preservation: Add Mild Preserved Eco™ and stir thoroughly.

This revised process ensures that your thickeners are fully hydrated and the pH is stabilized before the final serum structure is formed.
