Question
I am making a body cream using the following ingredients:
- Avocado Oil
- Rose Hip Oil
- Sweet Almond Oil
- Royal Jelly Extract
- Water
- Light Cream Maker
- Vitamin C (L-ascorbyl palmitate)
I have a few questions regarding the formulation process:
- What is the recommended mixing procedure for these ingredients to create a cream?
- How can I achieve a very thick texture for the cream? What percentage of Light Cream Maker is recommended for this, and can I increase the oil content?
- I want to add
Vitamin C (L-ascorbyl palmitate). The instructions mention mixing it with the oil phase at 70°C. Does this mean I need to boil the oil? After adding and dissolving the L-ascorbyl palmitate, should I wait for the oil phase to cool before adding the Light Cream Maker and the water phase?
Answer
Based on the conversation provided, here is a summary of how to make the body cream with your desired ingredients and texture:
Mixing Method:
- Separate your ingredients into an oil phase (Avocado Oil, Rose Hip Oil, Sweet Almond Oil) and a water phase (Royal Jelly Extract, Water).
- Add Light Cream Maker (start with 1-1.5%) to the oil phase and mix well.
- Pour the water phase into the oil phase and mix for about 3-5 minutes until a cream forms.
Achieving a Very Thick Texture:
- To increase the viscosity (make it thicker), you can increase the amount of Light Cream Maker used, for example, to 2-3%.
- To make the cream feel heavier or more occlusive on the skin, you can increase the total amount of oils in your formula, up to a maximum of 40% of the total formula weight.
Adding Vitamin C (L-ascorbyl palmitate):
- Yes, you can add L-ascorbyl palmitate. It is known for its high stability and good efficacy, but it is recommended to avoid sun exposure after using products containing it.
- To incorporate it, you should add it to the oil phase. Gently warm the oil phase to around 60-70°C while stirring continuously (do not boil the oils, as high heat can degrade natural oils).
- Add the L-ascorbyl palmitate to the warmed oil phase and stir until it dissolves completely.
- Remove from heat. You can then add the Light Cream Maker and the water phase while the oil phase is still warm or after it has cooled down. However, if your water phase contains any heat-sensitive active ingredients, it is best to wait for the oil phase to cool before combining the two phases.
