Anhydrous Vitamin C Serum Formulation with Isododecane and Cyclomethicone

Yes, this formulation is a correct and valid approach for creating an anhydrous Vitamin C serum.

Here's why:

• Anhydrous Base: L-Ascorbic Acid (Vitamin C) is highly stable in formulations that do not contain water. Using Isododecane and Cyclomethicone creates an anhydrous base, which helps preserve the potency of the Vitamin C.
• Ingredients:
  • Vitamin C (L-Ascorbic Acid) ultra-fine 15%: This is the active ingredient. 15% is an effective concentration commonly used in serums. The ultra-fine powder form is suitable for suspending in an anhydrous base.
  • Isododecane 25% and Cyclomethicone 60%: These are common volatile solvents and silicones used in cosmetics to create a lightweight, non-greasy feel. They act as the base to suspend the Vitamin C powder evenly.
• Percentages: The percentages add up to 100% and are within a reasonable range for this type of anhydrous suspension serum.

This type of formulation is a popular way to deliver stable L-Ascorbic Acid. Remember to ensure the Vitamin C powder is fully dispersed in the liquid base.
