Question
I have a serum formula containing water-soluble ingredients like REGU®-AGE, Aloe Vera Extract, Vitamin B3, and WhiteCumin™. The expert mentioned it appears to be a water-in-silicone or silicone-based serum.
I have three questions:
- Where exactly should I add the Mild Preserved™ preservative in this formula, especially if I am mixing without using heat?
- Is it necessary to use heat when mixing this type of serum (water-in-silicone or silicone-based)? What does 'using heat in cosmetic formulation' typically involve?
- Could you confirm the process for ordering and receiving products? Do I place the order online, pay via transfer, inform the company, and then either pick up or have it delivered?
Answer
Regarding your questions:
- Adding the preservative: Yes, based on the previous staff response, if your mixing process does not involve heating any ingredients, you can add the Mild Preserved™ to the water phase along with the other water-soluble ingredients (REGU®-AGE, Aloe Vera Extract, Vitamin B3, WhiteCumin™).
- Using heat in cream mixing: Using heat in cosmetic formulation typically refers to processes where ingredients (especially oils, waxes, and some emulsifiers) need to be heated to a specific temperature to melt or become miscible before being combined, often involving heating the water phase and oil phase separately to similar temperatures before emulsifying them. Your current serum formula, which appears to be a water-in-silicone or silicone-based serum, does not seem to require heating based on the ingredients listed.
- Purchasing and pickup: Your understanding is correct. You need to place your order online, complete the payment (transfer money), and then inform the company (e.g., by sending the slip). The company will prepare your order after receiving payment, and then you can either pick it up at the company location or have it delivered.
