Dry Shampoo Aerosol Formulation

Regarding the dry shampoo aerosol formulation using the store's Dry Shampoo Powder, the recommended ratio is indeed 8% powder.

The remaining 92% is Ethyl Alcohol, not just gas. The formulation you prepare before sending it for aerosol filling is a mixture of:

• Dry Shampoo Powder: 8%
• Ethyl Alcohol: 92%

The gas is added separately by the factory during the aerosol filling process. You only need to prepare the liquid/powder mixture according to the 8% powder and 92% alcohol ratio.

If you are using a regular spray bottle (non-aerosol), it might be possible, but as the staff mentioned, you would need to find a spray head with a large enough nozzle to dispense the powder effectively, as the dry shampoo is in powder form.
