Formulation Adjustment for Anti-Aging Cream: Gelling Agent and Stability

Hello! Thank you for sharing your formula for an anti-aging, lifting, and brightening cream and your questions. Based on the staff's advice regarding your formulation:

1. Regarding the use of Light Cream Maker™ (ID 141) with the Centella Asiatica Extract (ID 294):

   • The staff advises that Light Cream Maker™ may not be suitable for this formula, especially because it contains a relatively high amount of electrolytes, such as DMAE (ID 637).
   • Instead, they recommend using Pro Polymer (ID 234). Pro Polymer is more tolerant to electrolytes and can effectively create a gel texture while also helping to emulsify the oil-soluble Centella Asiatica extract into the formula.

2. Regarding the preservative (Phenoxyethanol, ID 155):

   • The staff confirms that Phenoxyethanol (ID 155) at 1% concentration is suitable for your formula.
   • Alternatively, you could also use Mild Preserved™ (Ethylhexylglycerin, ID 642) at a concentration of 0.8-1.0%.

3. Regarding the mixing procedure using Pro Polymer (ID 234):

   • Here are the recommended steps:
     • Combine the water-soluble ingredients (Argireline, Matrixyl 3000, DMAE, Vitamin B3, N-Acetyl-D glucosamine, and water) and mix until fully dissolved.
     • Add Pro Polymer (ID 234) to this mixture and stir to form a smooth gel texture.
     • Finally, add the oil-soluble ingredient (Centella Asiatica Extract, ID 294) to the gel and mix thoroughly until a cream texture is achieved.

Your formula includes several excellent active ingredients for your desired effects. Following the staff's recommendation to use Pro Polymer should help ensure a stable and effective cream texture.

Hope this helps!
