Hair Growth Spray Formulation with Sandal Pentanol

To create a hair growth spray for normal scalp using 5% Sandal Pentanol (Sandalore), you will need a solubilizer to disperse the oil-soluble Sandal Pentanol in a water base.

A suitable solubilizer for this purpose is PEG-40 Hydrogenated Castor Oil. It helps to incorporate oil-based ingredients into water-based formulations, making them suitable for spraying.

Here is a basic formulation guideline:

• Sandal Pentanol: 5%
• PEG-40 Hydrogenated Castor Oil: Start with a ratio of 1:1 up to 3:1 relative to Sandal Pentanol (e.g., 5% to 15%). The exact amount needed will depend on the specific Sandal Pentanol and PEG-40 Hydrogenated Castor Oil used and the desired clarity of the final product. You may need to adjust the ratio to achieve a clear solution.
• Water: Add up to 100% to complete the formula.
• Preservative: Add a suitable preservative at the manufacturer's recommended usage rate to prevent microbial growth.

Mixing Instructions:

1. Combine the Sandal Pentanol and PEG-40 Hydrogenated Castor Oil and mix well until the Sandal Pentanol is fully dissolved in the solubilizer.
2. In a separate container, measure out the water and preservative.
3. Gradually add the Sandal Pentanol/PEG-40 Hydrogenated Castor Oil mixture to the water phase while stirring or mixing continuously until a clear or uniformly dispersed solution is obtained.

Polysorbate 20 is another option for solubilization, but it might result in a slightly turbid solution compared to PEG-40 Hydrogenated Castor Oil when solubilizing oil-based ingredients.
