An essential oil dilution calculator is a vital tool used to determine the correct amount of essential oil to mix with a carrier oil or other base substance to achieve a desired concentration.
This calculator helps ensure safe and effective use of essential oils, as many oils are too potent to be applied directly to the skin without dilution.
The calculator typically requires inputs such as:
- The desired dilution percentage
- The total amount of the final product
- The type of carrier oil or base
It then outputs the amount of essential oil needed to achieve the desired dilution.
Sample Conversions:
- To create a 2% dilution in 30ml of carrier oil:
- Essential oil needed = 30ml × 2% = 0.6ml (approximately 12 drops)
- For a 5% dilution in 100ml of lotion:
- Essential oil needed = 100ml × 5% = 5ml (approximately 100 drops)
Essential Oil Dilution Calculator
| Desired Dilution | Carrier Oil Amount | Essential Oil Needed | Conversion Equation |
|---|---|---|---|
| 1% | 30ml | 0.3ml (6 drops) | 30ml × 1% = 0.3ml |
| 2% | 50ml | 1ml (20 drops) | 50ml × 2% = 1ml |
| 3% | 100ml | 3ml (60 drops) | 100ml × 3% = 3ml |
| 0.5% | 20ml | 0.1ml (2 drops) | 20ml × 0.5% = 0.1ml |
| 5% | 60ml | 3ml (60 drops) | 60ml × 5% = 3ml |
| 1.5% | 40ml | 0.6ml (12 drops) | 40ml × 1.5% = 0.6ml |
| 4% | 75ml | 3ml (60 drops) | 75ml × 4% = 3ml |

Essential Oil Dilution Calculation Formula
The basic formula for essential oil dilution is:
Amount of Essential Oil = Total Amount × Desired Dilution Percentage
This formula can be expressed in various units, such as milliliters, ounces, or drops.
Examples:
- Creating a 3% dilution in 50ml of carrier oil:
- Amount of Essential Oil = 50ml × 3% = 1.5ml
- Making a 1% dilution in 2 ounces of carrier oil:
- Amount of Essential Oil = 2oz × 1% = 0.02oz (approximately 0.6ml or 12 drops)
- Preparing a 0.5% dilution in 20ml of carrier oil:
- Amount of Essential Oil = 20ml × 0.5% = 0.1ml (approximately 2 drops)
What is Essential Oil Dilution?
Essential Oil Dilution is the process of mixing essential oils with a carrier substance to reduce their concentration. This practice is crucial for several reasons:
- Safety: Many essential oils are highly concentrated and can cause skin irritation, sensitization, or even toxicity if applied undiluted.
- Effectiveness: Dilution doesn’t necessarily reduce the effectiveness of essential oils. In fact, it can enhance absorption and distribution across a larger skin area.
- Economy: Dilution allows for more economical use of expensive essential oils.
- Customization: By diluting oils, you can create personalized blends tailored to specific needs or preferences.
Common carrier substances for dilution include:
- Vegetable oils (e.g., coconut, jojoba, almond)
- Lotions
- Gels
- Butters (e.g., shea butter, cocoa butter)
The appropriate dilution ratio depends on factors such as:
- The specific essential oil being used
- The intended application (e.g., massage, skincare, aromatherapy)
- The age and health status of the user
- The area of the body where it will be applied
What is the ratio for diluting essential oils?
Here are some general guidelines:
- For adults:
- General use: 2-5% dilution
- Face products: 0.5-1% dilution
- Bath and whole-body products: 1-2% dilution
- For children (2-12 years):
- General use: 1-2% dilution
- For infants (0-24 months):
- General use: 0.25-0.5% dilution
- For elderly or those with sensitive skin:
- General use: 1-2% dilution
- For acute situations (short-term use):
- Up to 10% dilution, under professional guidance
Remember, these are general guidelines. Always consult with a qualified aromatherapist or healthcare provider for personalized advice.
How many drops of essential oil for 1% dilution?
To achieve a 1% dilution, you need to add 1 drop of essential oil per 1ml of carrier oil.
- For 10ml of carrier oil: 3 drops of essential oil
- For 30ml (1 oz) of carrier oil: 6 drops of essential oil
- For 100ml of carrier oil: 20 drops of essential oil
However, since measuring tiny amounts can be challenging, it’s often easier to work with larger quantities
How do you calculate essential oil concentration?
To calculate essential oil concentration, use this formula:
Concentration (%) = (Volume of Essential Oil / Total Volume) × 100
For example, if you add 3ml of essential oil to 97ml of carrier oil:
Concentration = (3ml / 100ml) × 100 = 3%
Alternatively, if you know the desired concentration and total volume, you can calculate the amount of essential oil needed:
Volume of Essential Oil = (Desired Concentration × Total Volume) / 100
For instance, to create a 2% concentration in 50ml of product:
Volume of Essential Oil = (2 × 50ml) / 100 = 1ml
How to dilute essential oils with alcohol?
Diluting essential oils with alcohol is common in creating perfumes, room sprays, or cleaning products. Here’s how to do it:
- Choose a suitable alcohol, such as high-proof vodka or pure grain alcohol (ethanol).
- Determine your desired concentration (typically 1-5% for sprays).
- Calculate the amount of essential oil needed using the formula:
Essential Oil (ml) = Total Volume (ml) × Desired Concentration (%)
- Mix the essential oil with the alcohol in a glass container.
- If desired, add distilled water to reduce the alcohol content.
- Shake well before each use, as oil and water don’t mix permanently.
Example: For a 2% concentration in 100ml of spray:
- Essential oil needed: 100ml × 2% = 2ml
- Alcohol: 20-30ml
- Distilled water: Remainder (68-78ml)
