Adding Cedar Wood Oil to Water and Geranium Oil to Face Cream
คำถาม
I have two questions regarding adding oils to formulations:
- I want to add Cedar Wood Oil, which is oil-soluble, to a water-based product (100ml water). What intermediate is needed to mix it into the water? Also, how much Cedar Wood Oil should I add to 100ml of water?
- I have finished making a face cream based on a formulation recommended by staff. I don't like the smell and want to add Geranium Oil. Can I add it now to the finished cream? The recommended formulation is:
- Perfect-C TransDerm 10% [บำรุง/whitening]
- Vitamin B3 5% [ช่วยฟื้นฟูผิว]
- Repair Activator™ (Bifida Ferment Lysate) 10%
- Zinc PCA 1% [ลดความมันผิว ปรับสมดุล]
- Rice Vitamin 3% [ลดความมันผิว ปรับสมดุล]
- Pro Polymer 1.5% [สร้างเนื้อเจล/ครีม]
- Water (ส่วนที่เหลือ)
- Phenoxyethanol 0.8% [สารกันเสีย]

How to Add Oils to Your Formulations
Here's how you can incorporate Cedar Wood Oil into a water-based product and add Geranium Oil to your finished face cream:
Adding Cedar Wood Oil to Water
Cedar Wood Oil is an oil-soluble ingredient, meaning it doesn't naturally mix with water. To add it to a water-based product like 100ml of water, you will need a solubilizer such as Flora Solve Clear.
Method:
- Mix the Cedar Wood Oil with Flora Solve Clear first. The typical ratio is 2-5 parts Flora Solve Clear to 1 part essential oil. For many essential oils, a 2:1 or 3:1 ratio is sufficient, but some may require up to 5:1. You will need to test the ratio to ensure the mixture remains clear when added to water.
- Add this mixture of Cedar Wood Oil and Flora Solve Clear to your 100ml of water while stirring.
Recommended Amount:
A typical usage rate for essential oils in water-based products is low, usually between 0.1% and 0.5% of the total formula. For 100ml of water, this would be 0.1ml to 0.5ml of Cedar Wood Oil. Start with a lower amount and increase if needed, keeping in mind the recommended maximum usage for essential oils in your specific product type.
For example, if you use 0.1ml of Cedar Wood Oil, you would mix it with at least 0.2ml of Flora Solve Clear before adding to the water.
Adding Geranium Oil to Your Face Cream
Yes, you can add Geranium Oil to your finished face cream. Since your cream formulation already contains Pro Polymer, which acts as a gel maker and helps emulsify oils, you can add the Geranium Oil directly.
Method:
- Add the Geranium Oil drop by drop to your finished cream.
- Stir the cream thoroughly to ensure the oil is evenly dispersed.
Recommended Amount:
For a face cream, essential oils are typically used at a low concentration, usually between 0.1% and 0.5% of the total cream weight. Start with a small amount (e.g., 0.1%) and add more gradually until you achieve your desired scent strength. Avoid exceeding 0.5% in a face cream to minimize the risk of skin sensitivity.
Your cream formulation includes:
- Perfect-C TransDerm
- Vitamin B3
- Repair Activator
- Zinc PCA
- Rice Vitamin
- Pro Polymer
- Phenoxyethanol
The presence of Pro Polymer in this formulation allows for the direct addition of the Geranium Oil.
