Cream Color Change and Vitamin C Alternatives for Serum
Question
Based on the previous conversation about my cream turning brown due to Adenosine Complex, I would like to ask about alternatives for Vitamin C (L-ascorbic acid) Ultra-Fine, which is currently out of stock. I plan to use it in a serum formulation. What are the suitable alternative forms of Vitamin C, and what are their recommended usage percentages in a serum?
Answer
Cream Color Change and Vitamin C Substitution
Cream Color Change
The change in color of your cream formulation, turning from light orange to brown, was caused by the Adenosine Complex ingredient. As confirmed by the staff, Adenosine Complex has stability issues when combined with other ingredients, leading to discoloration (yellowing/browning). Due to these stability challenges requiring expert handling, Adenosine Complex is no longer available for retail purchase.
Vitamin C Substitution
Regarding the substitution for Vitamin C (L-ascorbic acid) Ultra-Fine, which is currently out of stock, there are several alternative forms of Vitamin C you could consider for your serum formulation:
- Vitamin C (Ascorbyl Tetraisopalmitate): This is an oil-soluble, stable form of Vitamin C. It is often used in oil-based serums or emulsions.
- Vitamin C (SAP - Sodium Ascorbyl Phosphate): This is a stable, water-soluble form of Vitamin C suitable for water-based formulations.
- Vitamin C (Ethyl Ascorbic Acid): Another stable, water-soluble form of Vitamin C that is known for good penetration.
The appropriate usage percentage for these alternatives would depend on the specific product and desired effect. You should refer to the product descriptions for recommended usage rates for each alternative.
We cannot provide an exact restock date for Vitamin C (L-ascorbic acid) Ultra-Fine.
