Question

I would like a suggested formulation for a facial spray essence aimed at skin brightening, firming, and acne reduction.

I plan to use liquid chitosan as the base and add the following ingredients:

  • Panthenol (Pro Vitamin B5)
  • Vitamin B3 (Niacinamide) Ultra-Low Niacin
  • Phenoxyethanol
  • Disodium EDTA
  • Azelaic Acid (Potassium Azeloyl Diglycinate)

Please advise on the appropriate quantities (percentages) for each of the ingredients I plan to add.

Answer

Subject: Suggested Formulation for Facial Spray Essence

Hello! Thank you for reaching out. You're looking to create a facial spray essence for brightening, firming, and acne reduction using liquid chitosan you already have, plus five additional ingredients you plan to order: Panthenol, Vitamin B3 (Niacinamide), Phenoxyethanol, Disodium EDTA, and Azelaic Acid (Potassium Azeloyl Diglycinate). You are asking for recommended percentages for each ingredient.

Creating a precise formulation requires testing, but I can provide a suggested starting point for the percentages of the ingredients you plan to add, based on common cosmetic usage. You will add these ingredients to your liquid chitosan base.

Here is a suggested formulation guide (percentages are by weight/volume of the final product):

  • Panthenol (Pro-Vitamin B5): 1% - 3% (For moisturizing and soothing)
  • Vitamin B3 (Niacinamide) Ultra-Low Niacin: 3% - 5% (For brightening, barrier support, and anti-acne)
  • Azelaic Acid (Potassium Azeloyl Diglycinate): 2% - 5% (For brightening, anti-redness, and anti-acne)
  • Disodium EDTA: 0.1% (As a chelating agent for stability)
  • Phenoxyethanol: 0.8% - 1% (As a preservative)
  • Your Liquid Chitosan: Add to make up 100% of the total formulation.

Example (for 100g total product):

  • Panthenol: 1g
  • Niacinamide: 3g
  • Potassium Azeloyl Diglycinate: 2g
  • Disodium EDTA: 0.1g
  • Phenoxyethanol: 0.8g
  • Your Liquid Chitosan: Add 100 - (1+3+2+0.1+0.8) = 93.1g

Important Considerations:

  • These are suggested starting points. You may need to adjust percentages based on the specific concentration of your liquid chitosan and the desired feel and efficacy.
  • Ensure all ingredients are compatible and soluble in your liquid chitosan base. You may need to gently heat or stir to dissolve solids.
  • Hygiene is critical during preparation to prevent microbial contamination. Use clean, sanitized equipment and containers.
  • The preservative (Phenoxyethanol) is included to help prevent microbial growth, but proper hygiene is still essential.
  • Always perform a small patch test on your skin before applying the product to your face.
  • Monitor the product over time for stability (clarity, color, odor, separation).

This formulation aims to combine the benefits of the listed ingredients with your chitosan base for the desired effects. Good luck with your project!
