Optimizing Facial Cream Formula for Normal Skin

Question

I have a facial cream formula for normal skin with the following ingredients and percentages: Perfect-C (Ascorbyl Tetraisopalmitate) 8%, Rose Hip Oil 10%, and Satin Cream Maker 1%.

Could you please advise on the following:

Is the oil percentage (Perfect-C 8%, Rose Hip Oil 10%) appropriate for normal skin?
Is it necessary to include Disodium EDTA if I am using distilled water?
What type of packaging is suitable for this cream?
Can I add essential oils such as Chamomile, Lavender, or Helichrysum? If so, at what percentage, and will they be compatible with Perfect-C?

Here is a review of your facial cream formula based on the feedback:

Formula Recommendations:
- For normal skin, it's recommended to reduce the total oil percentage. Specifically, reduce Perfect-C (Ascorbyl Tetraisopalmitate) to 3-5% (from 8%) and Rose Hip Oil to 5-7% (from 10%). The total oil phase should be around 15-18%.
- Increase the amount of Satin Cream Maker to at least 1.5% (from 1%) to ensure proper emulsification, especially with the oil content in the formula.
Disodium EDTA with Distilled Water:
- Even when using distilled water, it is recommended to include Disodium EDTA for added stability and confidence.
Packaging:
- If you are making the cream for personal trial use, any container is acceptable as it won't be stored for a long period.
- If you plan to produce it for sale, you should carefully consider appropriate packaging to maintain product stability.
Adding Essential Oils:
- You can add essential oils like Chamomile, Lavender, or Helichrysum to the formula for fragrance. They will not cause problems with Perfect-C (Ascorbyl Tetraisopalmitate).
- However, be aware that some essential oils can cause skin irritation. It is recommended to use them at a low concentration (0.1-0.5%).
