Formulation Advice and Hair Tonic Suitability

Here is a suggested mixing procedure for the formula you provided:

1. Water Phase: In a container, add Purified Water and Tetrasodium EDTA. Stir to dissolve.
2. Disperse Hydroxyethyl Cellulose into the water phase while stirring continuously. Heat the mixture to around 70°C and maintain stirring until the Hydroxyethyl Cellulose is fully dissolved and a gel forms.
3. Add Glycerin and Double Hyaluron Liquid to the water phase and stir until well combined.
4. Oil Phase: In a separate container, combine Rice Bran Oil, C12-15 Pareth-12, Pure-Oryzanol, and CoCool (containing Menthol). Gentle warming (around 60-70°C) may be needed to help dissolve the Pure-Oryzanol and CoCool in the oil phase. C12-15 Pareth-12 will act as a solubilizer.
5. Slowly add the oil phase mixture to the water phase while stirring continuously until the mixture is homogeneous.
6. Add Triethanolamine to adjust the pH if necessary and ensure the Hydroxyethyl Cellulose is fully hydrated.
7. Add a suitable preservative (not listed in your formula, but essential for product stability and safety). Mild Preserved Eco is a good option.

Regarding using this formula as a hair tonic for hair growth, while it contains beneficial ingredients like Pure-Oryzanol and Rice Bran Oil, the high concentration of CoCool (Menthol) at 15% might cause significant irritation to the scalp, especially in a leave-on product. Additionally, the inclusion of Hydroxyethyl Cellulose will likely result in a thicker consistency than typically desired for a sprayable hair tonic.

A more suitable approach for a sprayable hair tonic format is the formula suggested by the staff:

• Ethyl Alcohol
• Flora Solve Clear
• Pure-Oryzanol
• Mild Preserved Eco
• Ethoxydiglycol
• Water

This staff formula uses Ethyl Alcohol and Ethoxydiglycol as effective solvents and carriers to deliver active ingredients like Pure-Oryzanol to the scalp in a light, sprayable form. Pure-Oryzanol is known for its potential to help reduce hair loss. Flora Solve Clear helps to solubilize oil-based ingredients or fragrances in the water/alcohol base. Mild Preserved Eco provides preservation.
