Essential Oil Solubilizers: Creating Effective Water-Based Sprays
Creating aromatic room sprays, linen sprays, and shower spa mists with essential oils presents a common challenge: water and oil don’t naturally mix. Without proper solubilization, essential oils will separate and float to the top of water-based formulations, resulting in uneven distribution, potential irritation when concentrated oil contacts skin, and inconsistent fragrance experience. Solubilizers are specialized ingredients that help essential oils disperse evenly throughout water-based solutions, creating stable and effective aromatic sprays for your home and personal care.
What is a Solubilizer?
A solubilizer is an ingredient that helps disperse oils into water by forming micelles (tiny droplets) that encapsulate the oil molecules, allowing them to distribute evenly throughout the water base. This creates a clear, stable solution without the need for shaking before use.
Common Solubilizer for Essential Oils
Solubol (Traditional Standard)
Composition: Vegetal glycerin, water, soy lecithin, natural extract of coconut, trisodium citrate, ascorbic acid, citric acid, vitamin E acetate, sunflower oil, and rosemary extract
Usage Rate: 4:1 ratio (4 parts Solubol to 1 part essential oil), then diluted at least 20 times with water
Cost:
- 1 fl oz: $17.00
- 4 fl oz: $39.00
5 Cost Effective Alternatives to Solubol include:
- PlantaSol CCG
- Sunflower Solubilizer
- Olive Solubilizer
- Caprol Micro Express
PlantaMulse Liquid
Cost Analysis Based on Usage Rates
For this analysis, let’s calculate the cost to solubilize 5ml (approximately 100 drops) of essential oil, which would be enough for several batches of room spray:
Solubol
- Usage ratio: 4:1 (4 parts Solubol to 1 part essential oil)
- Amount needed for 5ml essential oil: 20ml (0.68 oz)
- Cost using 1 oz size ($17.00/oz): $17.00 × 0.68 oz = $11.56 per 5ml of essential oil
- Cost using 4 oz size ($9.75/oz): $9.75 × 0.68 oz = $6.63 per 5ml of essential oil
Caprol Micro Express (CME)
- Usage rate: 10-15% in final formulation
- For a typical 100ml spray with 5ml essential oil, you would need: 10-15ml CME
- Using the higher end (15ml = 0.51 oz): $1.99 × 0.51 oz = $1.01 per 5ml of essential oil
- Using bulk pricing ($1.15/oz): $1.15 × 0.51 oz = $0.59 per 5ml of essential oil
PlantaSol CCG
- Starting ratio: 1:1 with essential oil, can range up to 10%
- Amount needed for 5ml essential oil (at 1:1 ratio): 5ml (0.17 oz)
- Cost: $2.63 × 0.17 oz = $0.45 per 5ml of essential oil
- At maximum recommended usage (10% in a 100ml spray): 10ml (0.34 oz)
- Cost at maximum usage: $2.63 × 0.34 oz = $0.89 per 5ml of essential oil
Sunflower Solubilizer
- Usage rate: 0.5-6% in final formulation
- For a 100ml spray with 5ml essential oil, you would need: 0.5-6ml
- Using the higher end (6ml = 0.20 oz): $2.30 × 0.20 oz = $0.46 per 5ml of essential oil
Olive Solubilizer
- Usage rate: 0.5-6% in final formulation
- For a 100ml spray with 5ml essential oil, you would need: 0.5-6ml
- Using the higher end (6ml = 0.20 oz): $2.49 × 0.20 oz = $0.50 per 5ml of essential oil
Comparative Cost Ranking (Per 5ml of Essential Oil)
- PlantaSol CCG (1:1 ratio): $0.45
- Sunflower Solubilizer: $0.46
- Olive Solubilizer: $0.50
- Caprol Micro Express (bulk pricing): $0.59
- Caprol Micro Express (small quantity): $1.01
- PlantaSol CCG (at maximum 10% usage): $0.89
- Solubol (4 oz size): $6.63
- Solubol (1 oz size): $11.56
As you can see, when accounting for usage rates, Solubol is significantly more expensive than the alternatives – costing between 13-25 times more than the most economical option (PlantaSol at a 1:1 ratio).
