Using Water-Soluble Calendula Extract in Lotion
Question
I want to use Calendula Extract (Water Soluble) in my lotion formula. How should I mix it, especially with water and essential oils? Can I use it to replace Calendula-infused oil in my current formula which contains oat water, honey, Sweet Almond Oil, E-Wax, Vitamin E Oil, preservative, and essential oil? If so, what is the correct procedure to incorporate it?
Answer
Using Calendula Extract (Water Soluble) in Your Lotion Formula
Based on the information for Calendula Extract (Water Soluble), here's how to use it in your formulation:
Mixing with Water: Calendula Extract (Water Soluble) is designed to be mixed into the water phase of your formulation. The recommended usage rate is typically 1-5% of the total formula weight. You would add it directly to the water portion (like your oat water and honey) and stir to dissolve.
Mixing with Essential Oil: Calendula Extract (Water Soluble) cannot be mixed directly with essential oils. Essential oils are oil-soluble, while this extract is water-soluble. To combine them in a formula like a lotion, you need an emulsifier (like your E-Wax) to create a stable mixture of the water and oil phases.
Substituting for Calendula-Infused Oil in Your Lotion Formula: Yes, you can use Calendula Extract (Water Soluble) in your lotion formula, but you should add it to the water phase, not the oil phase where you would typically add an infused oil. In your specific formula:
- Combine the Calendula Extract (Water Soluble) with the oat water and honey (water phase).
- Combine the Sweet Almond Oil, E-Wax, and Vitamin E Oil (oil phase).
- Heat both phases separately according to your lotion-making process.
- Combine the heated phases and emulsify.
- Add the preservative and essential oils during the cool-down phase, as recommended for those ingredients.
Remember to follow the recommended usage rate of 1-5% for the Calendula Extract (Water Soluble) based on your total formula size.
